ARM: OMAP2+: PRM/CM: Move the stubbed prm and cm functions to prcm.c file and make them __weak
Some prm and cm registers read/write and status functions are built only for some custom OMAP2+ builds and are stubbed in header files for other builds under ifdef statements. But this results in adding new CONFIG_ARCH_OMAPXXX checks when SOCs are added in the future. So move them to a common place for OMAP2+ and make them 'weak' implementations. This way no new ifdefs would be required in the future and also cleans up the existing code. Signed-off-by: R Sricharan <r.sricharan@ti.com> [paul@pwsan.com: unsplit quoted strings; moved PRM functions to mach-omap2/prm_common.c; resolved sparse warnings] Signed-off-by: Paul Walmsley <paul@pwsan.com>
