This series is continuation of cleanup of OMAP GPIO driver and fixes. The cleanup include getting rid of cpu_is_* checks wherever possible, use of gpio_bank list instead of static array, use of unique platform specific value associated data member to OMAP platforms to avoid cpu_is_* checks. The series also include PM runtime support. Baseline: git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git Branch: wip/gpio-cleanup Test Details: - Compile tested for omap1_defconfig and omap2plus_defconfig. - OMAP1710-H3: Bootup test. - OMAP2430-SDP, OMAP3430-SDP, OMAP4430-SDP: Functional testing. - PM Testing on OMAP3430-SDP: retention, off_mode, system_wide suspend and gpio wakeup. Following patch is required for testing retention and off-mode: https://patchwork.kernel.org/patch/834372/ OMAP: PM: omap_device: fix device power domain callbacks v3: - Avoid use of wkup_set and wkup_clear registers. Instead use wkup_status register for all platforms. This is because on OMAP4 it is recommended not to use them. - Remove duplicate code in omap_gpio_mod_init() for handling the same for 32-bit and 16-bit GPIO bank widths. This is accomplished by having two functions to handle each case while assiging a common function pointer during initialization. - Remove OMAP16xx specific one time initialization from omap_gpio_mod_init(). Move it inside omap16xx_gpio_init(). - Avoid usage of USHRT_MAX to indicate undefined values. Use 0 instead. - In omap_gpio_suspend()/resume() functions remove code that checks if the feature is supported. Instead, assign these functions to struct platform_driver's suspend & resume function pointers for those OMAP platforms whcih support this feature. - Remove 'suspend_support' flag because it is redundant. Instead use wkup_* registers to decode the same information. - Restore context also when we don't know if the context is lost. - Make omap_gpio_save_context() and omap_gpio_restore_context() static. v2: - Do special handling of non-wakeup GPIOs only on OMAP2420. Avoid this handling on OMAP3430. - Isolate cleanups and fixes into separate set of patches. Keep the cleanup first followed by the fixes. - Avoid calling omap_gpio_get_context_loss() directly and instead call it through function pointer in pdata initialized during init. - workaround_enabled flag is not longer needed and is removed. - Call pwrdm_post_transition() before calling omap_gpio_resume_after_idle(). - In omap2_gpio_resume_after_idle() do context restore before handling workaround. - Use PM runtime framework. - Modify register offset names to : wkup_status, wkup_clear, wkup_set. Also use 'base + offset' for readibility in all relevant places. - Remove unwanted messages from commit section like TODO, etc. Charulatha V (15): GPIO: OMAP: Remove dependency on gpio_bank_count GPIO: OMAP2+: Use flag to identify wakeup domain GPIO: OMAP: Make gpio_context part of gpio_bank structure GPIO: OMAP: Fix pwrdm_post_transition call sequence GPIO: OMAP: Handle save/restore ctx in GPIO driver GPIO: OMAP2+: Make non-wakeup GPIO part of pdata GPIO: OMAP: Avoid cpu checks during module ena/disable GPIO: OMAP: Use wkup regs off/suspend support flag GPIO: OMAP: Use level/edge detect reg offsets GPIO: OMAP: Clean set_gpio_triggering function GPIO: OMAP15xx: Use pinctrl offset instead of macro GPIO: OMAP: Use readl in irq_handler for all access GPIO: OMAP: Remove bank->method & METHOD_* macros GPIO: OMAP: Fix bankwidth for OMAP7xx MPUIO GPIO: OMAP: Use PM runtime framework Tarun Kanti DebBarma (5): GPIO: OMAP: Remove hardcoded offsets in ctxt save/restore GPIO: OMAP: Use wkup_status for all SoCs GPIO: OMAP: Clean omap_gpio_mod_init function GPIO: OMAP: optimize suspend and resume functions GPIO: OMAP2+: Clean prepare_for_idle and resume_after_idle arch/arm/mach-omap1/gpio15xx.c | 7 +- arch/arm/mach-omap1/gpio16xx.c | 31 +- arch/arm/mach-omap1/gpio7xx.c | 14 +- arch/arm/mach-omap2/gpio.c | 47 ++- arch/arm/mach-omap2/pm34xx.c | 21 +- arch/arm/plat-omap/include/plat/gpio.h | 31 +- drivers/gpio/gpio-omap.c | 1070 +++++++++++++------------------- 7 files changed, 533 insertions(+), 688 deletions(-) -- 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
