* ARM: pxa: convert to multiplatformArnd Bergmann2022-05-071-70/+0
| | | | | | | | | PXA is now ready to be built into a single kernel with all the other ARMv5 platforms, so change the Kconfig bit to finish it off. The mach/uncompress.h support is the last bit that goes away, getting replaced with the normal DEBUG_LL based approach. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
* ARM: pxa: remove support for MTD_XIPArnd Bergmann2022-05-071-36/+0
| | | | | | | | | | | | | Using MTD-XIP does not work on multiplatform kernels because it requires SoC specific register accesses to be done from low-level flash handling functions in RAM while the rest of the kernel sits in flash. I found no evidence of anyone still actually using this feature, so remove it from PXA to avoid spending a lot of time on actually making it work. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* ARM: pxa: move plat-pxa to drivers/soc/Arnd Bergmann2022-05-071-1/+1
| | | | | | | | | | | | | | There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both of them should ideally not be needed at all, as there are proper subsystems to replace them. OTOH, they are self-contained and can simply be normal SoC drivers, so move them over there to eliminate one more of the plat-* directories.

| | | | | | | | | The sa1111.h header defines some constants using the bitfield macros, but those are only used on sa1100, not on pxa, and the users include the bitfield header through mach/hardware.h. Acked-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
* ARM: pxa: move clk register definitions to driverArnd Bergmann2022-05-072-114/+0
| | | | | | | | | | | | | | | The clock register definitions are now used (almost) exclusively in the clk driver, and that relies on no other mach/*.h header files any more. Remove the dependency on mach/pxa*-regs.h by addressing the registers as offsets from a void __iomem * pointer, which is either passed from a board file, or (for the moment) ioremapped at boot time from a hardcoded address in case of DT (this should be moved into the DT of course).

* cpufreq: pxa3: move clk register access to clk driverArnd Bergmann2022-05-071-5/+0
| | | | | | | | | | | | | | | The driver needs some low-level register access for setting the core and bus frequencies. These registers are owned by the clk driver, so move the low-level access into that driver with a slightly higher-level interface and avoid any machine header file dependencies.

* ASoC: pxa: ac97: use normal MMIO accessorsArnd Bergmann2022-05-071-102/+0
| | | | | | | | | | | | | | To avoid dereferencing hardwired constant pointers from a global header file, change the driver to use devm_platform_ioremap_resource for getting an __iomem pointer, and then using readl/writel on that. Each pointer dereference gets changed by a search&replace, which leads to a few overlong lines, but seems less risky than trying to clean up the code at the same time.

| | | | | | | | | | | | | | | | | The poodle audio driver shows its age by using a custom gpio api for the "locomo" support chip. In a perfect world, this would get converted to use gpiolib and a gpio lookup table.

* ARM/pxa/mfd/power/sound: Switch Tosa to GPIO descriptorsLinus Walleij2022-05-071-18/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tosa device (Sharp SL-6000) has a mishmash driver set-up for the Toshiba TC6393xb MFD that includes a battery charger and touchscreen and has some kind of relationship to the SoC sound driver for the AC97 codec. Other devices define a chip like this but seem only half-implemented, not really handling battery charging etc. This patch switches the Toshiba MFD device to provide GPIO descriptors to the battery charger and SoC codec. As a result some descriptors need to be moved out of the Tosa boardfile and new one added: all SoC GPIO resources to these drivers now comes from the main boardfile, while the MFD provide GPIOs for its portions. As a result we can request one GPIO from our own GPIO chip and drop two hairy callbacks into the board file. This platform badly needs to have its drivers split up and converted to device tree probing to handle this quite complex relationship in an orderly manner. I just do my best in solving the GPIO descriptor part of the puzzle. Please don't ask me to fix everything that is wrong with these driver to todays standards, I am just trying to fix one aspect. I do try to use modern devres resource management and handle deferred probe using new functions where appropriate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mach/hardware.h is included in lots of places, and it provides three different things on pxa: - the cpu_is_pxa* macros - an indirect inclusion of mach/addr-map.h - the __REG() and io_pv2() helper macros Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h headers, then change all the files that use mach/hardware.h to include the exact set of those three headers that they actually need, allowing for further more targeted cleanup. linux/soc/pxa/cpu.h can remain permanently exported and is now in a global location along with similar headers. pxa-regs.h and addr-map.h are only used in a very small number of drivers now and can be moved to arch/arm/mach-pxa/ directly when those drivers are to pass the necessary data as resources.

* License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-0210-0/+10

By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

* ARM: sa1100/pxa: fix MTD_XIP buildArnd Bergmann2017-07-271-3/+7
| | | | | | | | | | | | | | | | | | In commit 3169663ac5902 "ARM: sa11x0/pxa: convert OS timer registers to IOMEM", the definition of the OSCR macro was changed to be an __iomem pointer, but the same register is also used by the XIP code. This patch does the corresponding change here as well. On PXA, the IRQ register definitions were removed even earlier, in commit 5d284e353eb1 ("ARM: pxa: avoid accessing interrupt registers directly"). This patch unfortunately brings some of that back. An earlier version of my patch moved the code into an external function, which could not work for CONFIG_XIP_KERNEL+CONFIG_MTD_XIP, so this restores something close to the original code.

* ARM: pxa: magician: Add support for ADS7846 touchscreenPetr Cvek2017-06-141-0/+1
| | | | | | | | | | | | | | | | | | | This patch adds a support for ADS7846 touchscreen driver. The basic functionality was tested, x_plate_ohms and y_plate_ohms were physically measured. The value pressure_max was empirically set to match the measured range, which is affected by x_plate_ohms and ADS samples. The value of keep_vref_on should be set. A tested model (T-Mobile MDA Compact PM10A) doesn't seem to use Vref pin as the input from an external source. On this model the unset keep_vref_on cause high jitter of measured values. SPI framing pin (gpio_cs) must be used in GPIO mode due to an incompatible autoframing of PXA27x controller and ADS7846 device.

* | usb: gadget: pxa25x_udc: move register definitions from archArnd Bergmann2016-03-041-163/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ixp4xx and pxa25x both use this driver and provide a slightly different set of register definitions for it. Aside from that, the definition in the ixp4xx-regs.h header conflicts with the on in the pxa27x device driver when compile-testing that: In file included from ../drivers/usb/gadget/udc/pxa27x_udc.c:37:0: ../drivers/usb/gadget/udc/pxa27x_udc.h:26:0: warning: "UDCCR" redefined #define UDCCR 0x0000 /* UDC Control Register */ ^ In file included from ../arch/arm/mach-ixp4xx/include/mach/hardware.h:27:0, from ../arch/arm/mach-ixp4xx/include/mach/io.h:18, from ../arch/arm/include/asm/io.h:194, from ../include/linux/io.h:25, from ../include/linux/irq.h:24, from ../drivers/usb/gadget/udc/pxa27x_udc.c:23: ../arch/arm/mach-ixp4xx/include/mach/ixp4xx-regs.h:415:0: note: this is the location of the previous definition #define UDCCR IXP4XX_USB_REG(IXP4XX_USB_BASE_VIRT+0x0000) This addresses both issues by moving all the definitions into the pxa25x_udc driver itself.
