OMAP4 powerdomains have some inherent differences as compared to OMAP2/3 powerdomains, starting with register offsets being different to clubbing of multiple controls into one register and in some cases splitting of control into multiple registers. There are also new features like lowpowerstatechange bits and features like HW SAR which are no longer present in the older form. Supporting all these in the existing powerdomain framework would mean adding a lot of cpu_is_* checks which makes code unmaintainable going fwd. Hence this RFC series is an attempt to split the existing powerdomain framework into platform independent part (which does error checking, usecounting et al) which can be reused across OMAP's and hook up platform specific functions to do low level programming which varies across OMAP's. The series has a dependency on the following patch series http://marc.info/?l=linux-omap&m=128146137929118&w=2 http://marc.info/?l=linux-omap&m=128464495603506&w=2 This series along with all the dependent series patches can be found here git://gitorious.org/omap-pm/linux.git powerdomain-split Rajendra Nayak (6): OMAP: powerdomain: Move powerdomain.c from mach-omap2 to plat-omap OMAP: powerdomain: Infrastructure to put arch specific code OMAP: powerdomain: Arch specific funcs for state control OMAP: powerdomain: Arch specific funcs for logic control OMAP: powerdomain: Arch specific funcs for mem control OMAP: PRM: split the prm accessor api funcs for omap2/3 and omap4 Santosh Shilimkar (2): omap4: powerdomain: add context_offset field omap4: powerdomain: Add pwrdm_clear_all_prev_pwrst arch/arm/mach-omap2/Makefile | 10 +- arch/arm/mach-omap2/clockdomain.c | 16 +- arch/arm/mach-omap2/control.c | 8 +- arch/arm/mach-omap2/io.c | 5 +- arch/arm/mach-omap2/pm-debug.c | 4 +- arch/arm/mach-omap2/pm24xx.c | 48 ++-- arch/arm/mach-omap2/pm34xx.c | 98 +++--- arch/arm/mach-omap2/powerdomains.c | 111 ++++++ arch/arm/mach-omap2/powerdomains.h | 13 + arch/arm/mach-omap2/powerdomains2xxx.c | 212 ++++++++++++ arch/arm/mach-omap2/powerdomains44xx.c | 177 ++++++++++ arch/arm/mach-omap2/powerdomains44xx.h | 14 + arch/arm/mach-omap2/prcm.c | 123 +++++--- arch/arm/mach-omap2/prm.h | 26 +- arch/arm/plat-omap/Makefile | 6 +- arch/arm/plat-omap/include/plat/powerdomain.h | 24 ++- arch/arm/plat-omap/include/plat/prcm.h | 12 +- arch/arm/{mach-omap2 => plat-omap}/powerdomain.c | 399 ++++++---------------- 18 files changed, 868 insertions(+), 438 deletions(-) create mode 100644 arch/arm/mach-omap2/powerdomains.c create mode 100644 arch/arm/mach-omap2/powerdomains2xxx.c create mode 100644 arch/arm/mach-omap2/powerdomains44xx.c rename arch/arm/{mach-omap2 => plat-omap}/powerdomain.c (70%) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
