config PPC_MPC512x
bool "512x-based boards"
depends on 6xx
clk: mpc5xxx: switch to COMMON_CLK, retire PPC_CLOCK the setup before the change was - arch/powerpc/Kconfig had the PPC_CLOCK option, off by default - depending on the PPC_CLOCK option the arch/powerpc/kernel/clock.c file was built, which implements the clk.h API but always returns -ENOSYS unless a platform registers specific callbacks - the MPC52xx platform selected PPC_CLOCK but did not register any callbacks, thus all clk.h API calls keep resulting in -ENOSYS errors (which is OK, all peripheral drivers deal with the situation) - the MPC512x platform selected PPC_CLOCK and registered specific callbacks implemented in arch/powerpc/platforms/512x/clock.c, thus provided real support for the clock API - no other powerpc platform did select PPC_CLOCK the situation after the change is - the MPC512x platform implements the COMMON_CLK interface, and thus the PPC_CLOCK approach in arch/powerpc/platforms/512x/clock.c has become obsolete - the MPC52xx platform still lacks genuine support for the clk.h API while this is not a change against the previous situation (the error code returned from COMMON_CLK stubs differs but every call still results in an error) - with all references gone, the arch/powerpc/kernel/clock.c wrapper and the PPC_CLOCK option have become obsolete, as did the clk_interface.h header file the switch from PPC_CLOCK to COMMON_CLK is done for all platforms within the same commit such that multiplatform kernels (the combination of 512x and 52xx within one executable) keep working Cc: Mike Turquette <mturquette@linaro.org> Cc: Anatolij Gustschin <agust@denx.de> Cc: linux-arm-kernel@lists.infradead.org Cc: linuxppc-dev@lists.ozlabs.org Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>
