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/torvalds/linux-2.6.git Branch: master Commit: c6a389f Linux 3.1-rc4 Test Details: - Compile tested for omap1_defconfig and omap2plus_defconfig. - OMAP1710-H3: Bootup test pending due to non-availability of setup. As soon as the setup is available I will boot test and intimate. - OMAP2430/SDP, OMAP3430/SDP, OMAP4430/SDP, OMAP4430/Blaze: Functional testing. - PM Testing on OMAP3430-SDP: retention, off_mode, system_wide suspend and gpio wakeup. v6: - Save and restore debounce registers for proper driver operation. - Restore interrupt enable after all configuration to avoid spurious interrupts. - Restore dataout register before oe register. - Restore dataout into dataout_set or dataout based upon the OMAP version. - Change register name from wkup_status to wkup_en. - Remove wrapper around omap_pm_get_dev_context_loss_count(). Use it directly. Also, changed the signature of get_context_loss_count in pdata and bank structure from int to u32. - Use 'context' instead of 'ctx' for clarity wherever it is used. - Merged two patches into one which are related to bank_is_mpuio() modification. - Use shift operator instead of following: + .irqctrl = OMAP_MPUIO_GPIO_INT_EDGE / 2, - Remove redundant check from the following + if (bank_is_mpuio(bank)) { + if (bank->regs->wkup_status) <--- redundant check + mpuio_init(bank); - Change subject of following patch [PATCH v5 15/22] gpio/omap: use readl in irq_handler for all access into [PATCH 14/25] gpio/omap: remove unnecessary bit-masking for read access - Fix multi-line comments in [PATCH v5 20/22] gpio/omap: cleanup prepare_for_idle and resume_after_idle v5: - Reduce runtime callback overhead when *_get/put_sync() called from probe() and *_gpio_request/free(). - Dynamic context save within functions where context is modified instead of saving all context within a common function. - Removed call to mpuio_init() from omap_gpio_mod_init(). Both the functions are called once during initialization in *_gpio_probe(). Call to omap_gpio_mod_init() has been removed from omap_gpio_request() on the first access to gpio bank. One time initialization looks sufficient. - In *_gpio_irq_handler() use *_put_sync_suspend() instead of *_put_sync(). - Removed hardcoding of OMAP16xx sysconfig register value and instead defined an associated constant. - Removed *_get_sync() call from *_gpio_suspend() and *_put_sync() call from *_gpio_resume(). They got wrongly slipped into the code. - Removed following redundant zero allocated initialization from mach-omap2/gpio.c + pdata->regs->irqctrl = 0; + pdata->regs->edgectrl1 = 0; + pdata->regs->edgectrl2 = 0; - Removed following redundant code in gpio-omap.c -#define bank_is_mpuio(bank) ((bank)->method == METHOD_MPUIO) v4: - since all accesses to registers are 4-byte aligned, removing special checks and handling of 16 and 32-bit wide bank registers and instead use 32-bit read/write access consistently. - redundant usage of MOD_REG_BIT has been corrected and replaced with _gpio_rmw(). - omap_gpio_mod_init() function has been simplified further using _gpio_rmw(). - sysconfig register offset specific to omap16xx has been removed along with its usage. - additional logic to skip from suspend/resume: if (!bank->regs->wkup_status || !bank->suspend_wakeup) return 0; if (!bank->regs->wkup_status || !bank->saved_wakeup) return 0; - separated mpuio related changes into a different patch from the patch where wakeup status register related changes are done. - Incorrect replacement of !cpu_class_is_omap2() in gpio_irq_type() corrected: + if (!bank->regs->leveldetect0 && + (type & (IRQ_TYPE_LEVEL_LOW|IRQ_TYPE_LEVEL_HIGH))) return -EINVAL; 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 (10): gpio/omap: remove dependency on gpio_bank_count gpio/omap: 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 context in GPIO driver gpio/omap: make non-wakeup GPIO part of pdata gpio/omap: avoid cpu checks during module ena/disable gpio/omap: use pinctrl offset instead of macro gpio/omap: remove bank->method & METHOD_* macros gpio/omap: fix bankwidth for OMAP7xx MPUIO Nishant Menon (1): gpio/omap: save and restore debounce registers Nishanth Menon (3): gpio/omap: enable irq at the end of all configuration in restore gpio/omap: restore OE only after setting the output level gpio/omap: handle set_dataout reg capable IP on restore Tarun Kanti DebBarma (11): gpio/omap: further cleanup using wkup_en register gpio/omap: use level/edge detect reg offsets gpio/omap: remove hardcoded offsets in context save/restore gpio/omap: cleanup set_gpio_triggering function gpio/omap: cleanup omap_gpio_mod_init function gpio/omap: remove unnecessary bit-masking for read access gpio/omap: use pm-runtime framework gpio/omap: optimize suspend and resume functions gpio/omap: cleanup prepare_for_idle and resume_after_idle gpio/omap: skip operations in runtime callbacks gpio/omap: remove omap_gpio_save_context overhead arch/arm/mach-omap1/gpio15xx.c | 7 +- arch/arm/mach-omap1/gpio16xx.c | 47 ++- arch/arm/mach-omap1/gpio7xx.c | 14 +- arch/arm/mach-omap2/gpio.c | 36 +- arch/arm/mach-omap2/pm34xx.c | 21 +- arch/arm/plat-omap/include/plat/gpio.h | 29 +- drivers/gpio/gpio-omap.c | 1067 +++++++++++++------------------- 7 files changed, 530 insertions(+), 691 deletions(-)
