* ARM: pxa: add the number of DMA requestor linesRobert Jarzmik2016-02-261-1/+1
| | | | | | | | | | | Declare the number of DMA requestor lines per platform : - for pxa25x: 40 requestor lines - for pxa27x: 75 requestor lines - for pxa3xx: 100 requestor lines This information will be used to activate the DMA flow control or not.

* ARM: pxa: fix building without IWMMXTArnd Bergmann2016-02-011-2/+4
| | | | | | | | | | | | | | | | | | | | | | When CONFIG_IWMMXT, the pxa3xx and pxa27x suspend/resume code emits some xscale specific instructions, which are rejected by the assembler, because gcc is built with -march=armv5 -mtune=xscale and passes that option to the assembler: /tmp/cciHumzr.s:553: Error: selected processor does not support ARM mode `mra r2,r3,acc0' /tmp/cciHumzr.s:605: Error: selected processor does not support ARM mode `mar acc0,r2,r3' make[3]: *** [arch/arm/mach-pxa/pxa3xx.o] Error 1 /tmp/cci5MUNu.s:326: Error: selected processor does not support ARM mode `mra r2,r3,acc0' /tmp/cci5MUNu.s:367: Error: selected processor does not support ARM mode `mar acc0,r2,r3' make[3]: *** [arch/arm/mach-pxa/pxa27x.o] Error 1 Overriding with -Wa,-march=xscale no longer works, so instead I'm adding an explict ".arch_extension" directive in all four inline assembly statements, which should work even if they end up in a different order in the assembly output.

* ARM: pxa: fix DFI bus lockups on startupRobert Jarzmik2015-09-131-1/+20
| | | | | | | | | | | | | | | | | After the conversion of pxa architecture to common clock framework, the NAND clock can be disabled on startup if no nand driver claims it. In this case, it happens that if the bootloader used the NAND and set the DFI arbitration bit, the next access to a static memory controller area, such as an ethernet card, the system bus will stall, and the core will be stalled forever. Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit will be enabled the pxa3xx-nand driver on need anyway. The only left requirement is that upon pxa3xx-nand removal, the bit should be cleared before the clock is disabled. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
* rtc: pxa: convert to use shared sa1100 functionsRob Herring2015-09-051-1/+0
| | | | | | | | | | | | | | | | | | | | | | | Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a superset of functionality. Having 2 drivers sharing the same memory resource is not allowed by the driver model if resources are properly declared. This problem was avoided by not adding memory resources to the SA1100 RTC driver, but that prevents clean-up of the SA1100 driver. This commit converts the PXA RTC to use the exported SA1100 RTC functions. Now the sa1100-rtc and pxa-rtc devices are mutually exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

| * ARM: pxa: transition to dmaengine phase 1Robert Jarzmik2015-07-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | In order to slowly transition pxa to dmaengine, the legacy code will now rely on dmaengine to request a channel. This implies that PXA architecture selects DMADEVICES and PXA_DMA, which is not pretty. Yet it enables PXA drivers to be ported one by one, with part of them using dmaengine, and the other part using the legacy code. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
* | ARM: kill off set_irq_flags usageRob Herring2015-07-281-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

| | | | | | | | | | | | | Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files.

* ARM: pxa3xx: provide specific platform_devices for all ssp portsDaniel Mack2014-09-191-7/+7
| | | | | | | | | | | | | | | | Currently, devices for SSP ports 1, 2 and 3 are registered as compatible devices to pxa27x-ssp. While the actual IP core is comparable, there are some subtle differences which users of the SSP ports address by looking at the 'type' field. By registering devices of type 'pxa27x-ssp', this 'type' field is incorrectly set to PXA27x_SSP which confuses the users. To fix this, provide specific ssp port plaform devices which use 'pxa3xx-ssp' as driver name, an instantiate them from pxa3xx.c.

That includes the following changes: - cpu_has_ipr() was converted from an inline function to a static bool variable, so it can be set using the "marvell,intc-priority" property inside the device node of the tree. - IRQ_BASE was converted from a macro to a runtime variable so that it can be initialized dynamically from the DT init code. - irq_base() now uses pxa_irq_base and just adds an offset.

* | ARM: pm: allow suspend finisher to return error codesRussell King2011-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are SoCs where attempting to enter a low power state is ignored, and the CPU continues executing instructions with all state preserved. It is over-complex at that point to disable the MMU just to call the resume path. Instead, allow the suspend finisher to return error codes to abort suspend in this circumstance, where the cpu_suspend internals will then unwind the saved state on the stack. Also omit the tlb flush as no changes to the page tables will have happened. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | ARM: pm: hide 1st and 2nd arguments to cpu_suspend from platform codeRussell King2011-06-241-1/+2
| | | | | | | | | | | | | | | | | | The first and second arguments shouldn't concern platform code, so hide them from each platforms caller. Tested-by: Kevin Hilman <khilman@ti.com> Acked-by: Jean Pihet <j-pihet@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | ARM: pm: pxa: move cpu_suspend into C codeRussell King2011-06-241-2/+11
|/ | | | | | | | We don't need a veneer for cpu_suspend, it can be called directly from C code now. Move it into the PXA CPU suspend functions, along with the accumulator register saving/restoring. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM / PXA: Use struct syscore_ops for "core" power managementRafael J. Wysocki2011-04-241-19/+6
| | | | | | | | | | | | | Replace sysdev classes and struct sys_device objects used for "core" power management by the PXA platform code with struct syscore_ops objects that are simpler. This reduces the code size and the kernel memory footprint. It also is necessary for removing sysdevs entirely from the kernel in the future. Signed-off-by: Rafael J.

* ARM: pxa2xx: reorganize I2C filesSebastian Andrzej Siewior2011-03-211-1/+1
| | | | | | | | | | | | | | | | | This patch moves the platform data definition from arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so it can be accessed from x86 the same way as on ARM. This change should make no functional change to the PXA code. The move is verified by building the following defconfigs: cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig raumfeld_defconfig magician_defconfig mmp2_defconfig pxa168_defconfig pxa910_defconfig Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
