Hi, This is the third version of the patch series for adding basic suspend-resume support for AM33XX, previously submitted by Vaibhav Bedia. This patchset is based on 3.11-rc4 and depends on a forthcoming patchset from Suman Anna that adds mailbox support for the wkup_m3. The patches at [1], [2], and [3] are required for the pm code to properly suspend and resume. The PM code uses the firmware interface and expects the userspace to load the WKUP_M3 binary before the suspend-resume functionality is made available. The binary file (and the source-code for WKUP_M3) can be obtained from the 'next2' branch at [4]. The WKUP_M3 binary can either be loaded post bootup via the sysfs entry './sys/devices/ocp.2/wkup_m3.4/firmware' or it can be included in the kernel image as part of the build process. Suspend to mem is tested on am335x-bone and am335x-evm. More details on AM335x suspend-resume are provided within the commit logs for each patch. Changes in v3: - Moved wkup_m3 code into separate driver - Split up ti_emif header move - Addressed clean-up comments - Removed mailbox patches - v2-v3 Discussion: http://marc.info/?l=linux-arm-kernel&m=135698501821090&w=4 Changes in v2: - Broke patches up to isolate assembly code and build hookup. - Moved control module code to separate module - v1->v2 Discussion: http://lists.infradead.org/pipermail/linux-arm-kernel/2012-November/129508.html Regards, Dave [1] http://marc.info/?l=linux-arm-kernel&m=137303736714638&w=4 [2] http://marc.info/?l=linux-omap&m=137303723114610&w=4 [3] http://marc.info/?l=linux-omap&m=137401384611934&w=4 [4] http://arago-project.org/git/projects/?p=am33x-cm3.git;a=shortlog;h=refs/heads/next2 Dave Gerlach (1): memory: emif: Move EMIF register defines to include/linux/ Vaibhav Bedia (8): ARM: OMAP2+: AM33XX: control: Add some control module registers and APIs ARM: OMAP: DTB: Update IRQ data for WKUP_M3 ARM: OMAP2+: AM33XX: Reserve memory to comply with EMIF spec ARM: OMAP2+: AM33XX: Add assembly code for PM operations ARM: OMAP2+: timer: Add suspend-resume callbacks for clkevent device ARM: OMAP: omap_device: Add APIs to enable and idle hwmods ARM: OMAP2+: AM33XX: Basic suspend resume support ARM: OMAP2+: AM33XX: Hookup AM33XX PM code into OMAP builds arch/arm/boot/dts/am33xx.dtsi | 1 + arch/arm/mach-omap2/Kconfig | 7 +- arch/arm/mach-omap2/Makefile | 2 + arch/arm/mach-omap2/board-generic.c | 3 +- arch/arm/mach-omap2/common.c | 28 ++ arch/arm/mach-omap2/common.h | 14 + arch/arm/mach-omap2/control.c | 57 ++++ arch/arm/mach-omap2/control.h | 54 ++++ arch/arm/mach-omap2/io.c | 6 + arch/arm/mach-omap2/omap_device.c | 8 + arch/arm/mach-omap2/omap_device.h | 2 + arch/arm/mach-omap2/pm.c | 3 +- arch/arm/mach-omap2/pm.h | 5 + arch/arm/mach-omap2/pm33xx.c | 474 +++++++++++++++++++++++++++++ arch/arm/mach-omap2/pm33xx.h | 77 +++++ arch/arm/mach-omap2/sleep33xx.S | 350 ++++++++++++++++++++++ arch/arm/mach-omap2/sram.c | 10 +- arch/arm/mach-omap2/sram.h | 2 + arch/arm/mach-omap2/timer.c | 32 ++ arch/arm/mach-omap2/wkup_m3.c | 183 ++++++++++++ drivers/memory/emif.h | 543 +--------------------------------- include/linux/ti_emif.h | 558 +++++++++++++++++++++++++++++++++++ 22 files changed, 1872 insertions(+), 547 deletions(-) create mode 100644 arch/arm/mach-omap2/pm33xx.c create mode 100644 arch/arm/mach-omap2/pm33xx.h create mode 100644 arch/arm/mach-omap2/sleep33xx.S create mode 100644 arch/arm/mach-omap2/wkup_m3.c create mode 100644 include/linux/ti_emif.h -- 1.7.9.5 -- 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
