ALSA: pxa2xx: Use guard() for mutex locks

2025-09-01T11:54:27Z

Replace the manual mutex lock/unlock pairs with guard() for code simplification. Only code refactoring, and no behavior change. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250829151335.7342-16-tiwai@suse.de

ARM: pxa: fix missing-prototypes warnings

2023-05-26T11:33:05Z

The PXA platform has a number of configurations that end up with a warning like these when building with W=1: drivers/hwmon/max1111.c:83:5: error: no previous prototype for 'max1111_read_channel' [-Werror=missing-prototypes] arch/arm/mach-pxa/reset.c:86:6: error: no previous prototype for 'pxa_restart' [-Werror=missing-prototypes] arch/arm/mach-pxa/mfp-pxa2xx.c:254:5: error: no previous prototype for 'keypad_set_wake' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa25x.c:70:14: error: no previous prototype for 'pxa25x_get_clk_frequency_khz' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa25x.c:325:12: error: no previous prototype for 'pxa25x_clocks_init' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:74:14: error: no previous prototype for 'pxa27x_get_clk_frequency_khz' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:102:6: error: no previous prototype for 'pxa27x_is_ppll_disabled' [-Werror=missing-prototypes] drivers/clk/pxa/clk-pxa27x.c:470:12: error: no previous prototype for 'pxa27x_clocks_init' [-Werror=missing-prototypes] arch/arm/mach-pxa/pxa27x.c:44:6: error: no previous prototype for 'pxa27x_clear_otgph' [-Werror=missing-prototypes] arch/arm/mach-pxa/pxa27x.c:58:6: error: no previous prototype for 'pxa27x_configure_ac97reset' [-Werror=missing-prototypes] arch/arm/mach-pxa/spitz_pm.c:170:15: error: no previous prototype for 'spitzpm_read_devdata' [-Werror=missing-prototypes] The problem is that there is a declaration for each of these, but it's only seen by the caller and not the callee. Moving these into appropriate header files ensures that both use the same calling conventions and it avoids the warnings.

ALSA: arm: pxa: pxa2xx-ac97-lib: fix return value check of platform_get_irq()

2022-10-29T08:45:27Z

platform_get_irq() returns negative error number on failure, fix the return value check in pxa2xx_ac97_hw_probe() and assign the error code to 'ret'.

ASoC: pxa: ac97: use normal MMIO accessors

2022-05-07T20:55:49Z

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.

Input: touchscreen: use wrapper for pxa2xx ac97 registers

2022-05-07T20:55:48Z

To avoid a dependency on the pxa platform header files with hardcoded registers, change the driver to call a wrapper in the pxa2xx-ac97-lib that encapsulates all the other ac97 stuff.

ARM: pxa: pxa2xx-ac97-lib: use IRQ resource

2022-04-19T19:34:05Z

The pxa2xx-ac97-lib code is the last driver to use mach/irqs.h for PXA. Almost everything already passes the interrupt as a resource, so use it from there. The one exception is the mxm8x10 machine, which apparently has a resource-less device. Replacing it with the correct one enables the driver here as well.

ARM: pxa: move mach/sound.h to linux/platform_data/

ARM: pxa: split up mach/hardware.h

2022-04-19T14:27:05Z

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 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.
