Russell, * Dave Gerlach <d-gerlach@xxxxxx> [170328 19:01]: > Most of the PM code needed for am335x and am437x can be moved into a > module under drivers but some core code must remain in mach-omap2 at the > moment. This includes some internal clockdomain APIs and low-level ARM > APIs which are also not exported for use by modules. > > Implement a few functions that handle these low-level platform > operations can be passed to the pm33xx module through the use of > platform data. > > In addition to this, to be able to share data structures between C and > the sleep33xx and sleep43xx assembly code, we can automatically generate > all of the C struct member offsets and sizes as macros by making use of > the ARM asm-offsets file. In the same header that we define our data > structures in we also define all the macros in an inline function and by > adding a call to this in the asm_offsets file all macros are properly > generated and available to the assembly code without cluttering up the > asm-offsets file. > > Signed-off-by: Dave Gerlach <d-gerlach@xxxxxx> > --- > arch/arm/kernel/asm-offsets.c | 2 + > arch/arm/mach-omap2/Kconfig | 1 + > arch/arm/mach-omap2/Makefile | 4 + > arch/arm/mach-omap2/pm.h | 5 + > arch/arm/mach-omap2/pm33xx-core.c | 181 +++++++++++++++++++++++++++++++++++ > include/linux/platform_data/pm33xx.h | 69 +++++++++++++ > 6 files changed, 262 insertions(+) > create mode 100644 arch/arm/mach-omap2/pm33xx-core.c > create mode 100644 include/linux/platform_data/pm33xx.h > > diff --git a/arch/arm/kernel/asm-offsets.c b/arch/arm/kernel/asm-offsets.c > index d728b5660e36..62253e7bfac4 100644 > --- a/arch/arm/kernel/asm-offsets.c > +++ b/arch/arm/kernel/asm-offsets.c > @@ -28,6 +28,7 @@ > #include <asm/vdso_datapage.h> > #include <asm/hardware/cache-l2x0.h> > #include <linux/kbuild.h> > +#include <linux/platform_data/pm33xx.h> > #include <linux/ti-emif-sram.h> > > /* > @@ -187,6 +188,7 @@ int main(void) > #if defined(CONFIG_SOC_AM33XX) || defined(CONFIG_SOC_AM43XX) > BLANK(); > ti_emif_offsets(); > + amx3_pm_asm_offsets(); > #endif > > return 0; Here too can you please check this is OK with you.
