powerpc: Add missing headers

2022-05-08T12:15:40Z

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.

powerpc: Remove asm/prom.h from all files that don't need it

powerpc/83xx/mpc8349emitx: Get rid of of_node assignment

2022-04-20T22:42:47Z

Let GPIO library to assign of_node from the parent device. This allows to move GPIO library and drivers to use fwnode APIs instead of being stuck with OF-only interfaces.

powerpc/83xx: Add __init attribute to eligible functions

2021-12-23T11:33:18Z

Some functions defined in 'arch/powerpc/platforms/83xx' are deserving of an `__init` macro attribute. These functions are only called by other initialization functions and therefore should inherit the attribute. Also, change function declarations in header files to include `__init`.

powerpc/83xx/mpc8349emitx: Drop unused variable

2021-11-15T04:46:45Z

Commit 5d354dc35ebb ("powerpc/83xx/mpc8349emitx: Make mcu_gpiochip_remove() return void") removed the usage of the variable ret, but failed to remove the variable itself, resulting in: arch/powerpc/platforms/83xx/mcu_mpc8349emitx.c: In function ‘mcu_remove’: arch/powerpc/platforms/83xx/mcu_mpc8349emitx.c:189:6: error: unused variable ‘ret’ [-Werror=unused-variable] 189 | int ret; | ^~~ So remove the variable now.

powerpc/83xx/mpc8349emitx: Make mcu_gpiochip_remove() return void

2021-10-27T13:41:29Z

Up to now mcu_gpiochip_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c remove callbacks is ignored anyway.

powerpc: Use simple i2c probe function

2020-09-02T01:00:20Z

The i2c probe functions here don't use the id information provided in their second argument, so the single-parameter i2c probe function ("probe_new") can be used instead. This avoids scanning the identifier tables during probes.
