* MIPS: DTS: CI20: Raise VDDCORE voltage to 1.125 voltsPaul Cercueil2023-06-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | Commit 08384e80a70f ("MIPS: DTS: CI20: Fix ACT8600 regulator node names") caused the VDDCORE power supply (regulated by the ACT8600's DCDC1 output) to drop from a voltage of 1.2V configured by the bootloader, to the 1.1V set in the Device Tree. According to the documentation, the VDDCORE supply should be between 0.99V and 1.21V; both values are therefore within the supported range. However, VDDCORE being 1.1V results in the CI20 being very unstable, with corrupted memory, failures to boot, or reboots at random. The reason might be succint drops of the voltage below the minimum required. Raising the minimum voltage to 1.125 volts seems to be enough to address this issue, while still keeping a relatively low core voltage which helps for power consumption and thermals.

* MIPS: DTS: CI20: Enable support for WiFi / BluetoothPaul Cercueil2023-06-091-15/+73
| | | | | | | | | | | | | | | | | | Wire the WiFi/Bluetooth chip properly in the Device Tree. - Provide it with the correct regulators and clocks; - Change the MMC I/O bus to 1.8V which seems to be enough; - Change the MMC I/O bus frequency to 25 MHz as 50 MHz causes errors; - Fix the Bluetooth powerdown GPIO being inverted and add reset GPIO; - Convert host-wakeup-gpios to IRQ. With these changes, the WiFi works properly with the latest firmware provided by linux-firmware. The Bluetooth does not work very well here, as I cannot get my wireless keyboard to pair; but it does detect it, and it does see the key presses when I type the pairing code.

* MIPS: DTS: CI20: Parent MSCMUX clock to MPLLPaul Cercueil2023-06-091-2/+3
| | | | | | | | | This makes it possible to clock the SD cards much higher, as the MPLL is running at 1.2 GHz by default. The previous parent was the EXT clock, which caused the SD cards to be clocked at 24 MHz maximum.

* MIPS: DTS: CI20: Fix ACT8600 regulator node namesPaul Cercueil2023-06-091-19/+8
| | | | | | | | | | | | | | | | | | | The Device Tree was using invalid node names for the ACT8600 regulators. To be fair, it is not the original committer's fault, as the documentation did gives invalid names as well. In theory, the fix should have been to modify the driver to accept the alternative names. However, even though the act8865 driver spits warnings, the kernel seemed to work fine with what is currently supported upstream. For that reason, I think it is okay to just update the DTS. I removed the "regulator-name" too, since they really didn't bring any information. The node names are enough.

| | | | | | | | | | The regulators don't have any "reg" property, and therefore shouldn't use an unit address in their node names. They also don't need to specify the GPIO_ACTIVE_LOW flag, which will be ignored anyway, as they are active-high.

| | | | | | | | | | | | | | | | The reset line is called PWRST#, annotated as "active low" in the binding documentation, and is driven low and then high by the driver to reset the chip. However in device tree for CI20 board it was incorrectly marked as "active high". Fix it. Because (as far as I know) the ci20.dts is always built in the kernel I elected not to also add a quirk to gpiolib to force the polarity there.

* License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add device tree nodes for the NEMC and BCH to the JZ4780 device tree, and make use of them in the Ci20 device tree to add a node for the board's NAND. Note that since the pinctrl driver is not yet upstream, this includes neither pin configuration nor busy/write-protect GPIO pins for the NAND. Use of the NAND relies on the boot loader to have left the pins configured in a usable state, which should be the case when booted from the NAND.
