ARM: pxa: convert to multiplatform

2022-05-07T20:56:17+00:00

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

ARM: pxa: remove support for MTD_XIP

2022-05-07T20:56:17+00:00

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

ARM: pxa: move mach/*.h to mach-pxa/

2022-05-07T20:56:17+00:00

None of the headers are included from outside of the mach-pxa directory, so move them all in there. Signed-off-by: Arnd Bergmann

ARM: pxa: move plat-pxa to drivers/soc/

2022-05-07T20:56:16+00:00

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.

ARM: pxa: remove unused mach/bitfield.h

2022-05-07T20:56:16+00:00

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 Signed-off-by: Arnd Bergmann

ARM: pxa: move clk register definitions to driver

2022-05-07T20:55:49+00:00

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 driver

2022-05-07T20:55:49+00:00

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 accessors

2022-05-07T20:55:49+00:00

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.

ARM: pxa: spitz: use gpio descriptors for audio

2022-05-07T20:55:47+00:00

The audio driver should not use a hardwired gpio number from the header. Change it to use a lookup table. Acked-by: Mark Brown Cc: alsa-devel@alsa-project.org Reviewed-by: Linus Walleij Signed-off-by: Arnd Bergmann

ARM: pxa: lubbock: pass udc irqs as resource

2022-05-07T20:55:47+00:00

Lubbock is the only machine that has three IRQs for the UDC. These are currently hardcoded in the driver based on a machine header file. Change this to use platform device resources as we use for the generic IRQ anyway.
