This patch series makes OMAP2PLUS specific GPIO implemented in HWMOD FW way. This is done by implementing GPIO module in platform device model. This patch series is generated on "origin/pm-wip/hwmods-omap4". This patch series is created on top of the following two patches: - OMAP4: HWMOD: Do omap_hwmod_late_init for OMAP4 - musb: Kill board specific pinmux from driver file http://marc.info/?l=linux-usb&m=127858711304301&w=2 - Revert the following patch: OMAP: bus-level PM: enable use of runtime PM API for suspend/resume http://dev.omapzoom.org/?p=swarch/linux-omap-adv.git;a=commitdiff;h=8041359e18e49bf8a3d41f15894db9e476f3a8fc (or) Remove the locking in the omap_hwmod_for_each* function This patch series is tested on OMAP4430 SDP board and OMAP3430 SDP board. It would be of great help if someone could test the same on OMAP1 and OMAP2 boards.

SoC specific gpio_init needs to be done before machine_init functions access gpio APIs. Hence making SoC specific gpio_init as postcore_initcall. - getting gpio dbck is moved to omap_set_gpio_debounce() instead of doing it in probe v1 series: Some important links to patch v1 series and comments: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg26934.html http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg27860.html http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg28183.html Highlights in v1: - Introduces SoC specific functions at mach-omap layer - Implements GPIO as a platform device - Make gpio an early device and make it implemented in HWMOD FW adapted way for OMAP2PLUS Charulatha V (13): OMAP: GPIO: Modify init() in preparation for platform device implementation OMAP: GPIO: Introduce support for OMAP15xx chip GPIO init OMAP: GPIO: Introduce support for OMAP16xx chip GPIO init OMAP: GPIO: Introduce support for OMAP7xx chip GPIO init OMAP: GPIO: add GPIO hwmods structures for OMAP3 OMAP: GPIO: add GPIO hwmods structures for OMAP242X OMAP: GPIO: add GPIO hwmods structures for OMAP243X OMAP: GPIO: Add gpio dev_attr and correct clks in OMAP4 hwmod struct OMAP: GPIO: Introduce support for OMAP2PLUS chip GPIO init OMAP: GPIO: Implement GPIO as a platform device OMAP: GPIO: Make gpio_context as part of gpio_bank structure OMAP: GPIO: Use dev_pm_ops instead of sys_dev_class OMAP: GPIO: Remove omap_gpio_init() arch/arm/mach-omap1/Makefile | 6 + arch/arm/mach-omap1/board-ams-delta.c | 1 - arch/arm/mach-omap1/board-fsample.c | 1 - arch/arm/mach-omap1/board-h2.c | 1 - arch/arm/mach-omap1/board-h3.c | 1 - arch/arm/mach-omap1/board-htcherald.c | 1 - arch/arm/mach-omap1/board-innovator.c | 1 - arch/arm/mach-omap1/board-nokia770.c | 1 - arch/arm/mach-omap1/board-osk.c | 1 - arch/arm/mach-omap1/board-palmte.c | 1 - arch/arm/mach-omap1/board-palmz71.c | 1 - arch/arm/mach-omap1/board-perseus2.c | 1 - arch/arm/mach-omap1/board-sx1.c | 1 - arch/arm/mach-omap1/board-voiceblue.c | 1 - arch/arm/mach-omap1/clock_data.c | 4 +- arch/arm/mach-omap1/gpio15xx.c | 101 +++ arch/arm/mach-omap1/gpio16xx.c | 208 +++++ arch/arm/mach-omap1/gpio7xx.c | 274 ++++++ arch/arm/mach-omap2/Makefile | 2 +- arch/arm/mach-omap2/board-2430sdp.c | 1 - arch/arm/mach-omap2/board-3430sdp.c | 1 - arch/arm/mach-omap2/board-3630sdp.c | 1 - arch/arm/mach-omap2/board-4430sdp.c | 1 - arch/arm/mach-omap2/board-am3517evm.c | 1 - arch/arm/mach-omap2/board-apollon.c | 1 - arch/arm/mach-omap2/board-cm-t35.c | 1 - arch/arm/mach-omap2/board-devkit8000.c | 1 - arch/arm/mach-omap2/board-h4.c | 1 - arch/arm/mach-omap2/board-igep0020.c | 1 - arch/arm/mach-omap2/board-ldp.c | 1 - arch/arm/mach-omap2/board-n8x0.c | 1 - arch/arm/mach-omap2/board-omap3beagle.c | 1 - arch/arm/mach-omap2/board-omap3evm.c | 1 - arch/arm/mach-omap2/board-omap3pandora.c | 1 - arch/arm/mach-omap2/board-omap3stalker.c | 1 - arch/arm/mach-omap2/board-omap3touchbook.c | 1 - arch/arm/mach-omap2/board-omap4panda.c | 1 - arch/arm/mach-omap2/board-overo.c | 1 - arch/arm/mach-omap2/board-rx51.c | 1 - arch/arm/mach-omap2/board-zoom2.c | 1 - arch/arm/mach-omap2/board-zoom3.c | 1 - arch/arm/mach-omap2/gpio.c | 120 +++ arch/arm/mach-omap2/omap_hwmod_2420_data.c | 234 ++++++ arch/arm/mach-omap2/omap_hwmod_2430_data.c | 290 +++++++ arch/arm/mach-omap2/omap_hwmod_3xxx_data.c | 382 +++++++++ arch/arm/mach-omap2/omap_hwmod_44xx_data.c | 40 +- arch/arm/mach-omap2/pm24xx.c | 4 +- arch/arm/mach-omap2/pm34xx.c | 23 +- arch/arm/plat-omap/gpio.c | 1259 ++++++++++++---------------- arch/arm/plat-omap/include/plat/gpio.h | 29 +- 50 files changed, 2208 insertions(+), 803 deletions(-) create mode 100644 arch/arm/mach-omap1/gpio15xx.c create mode 100644 arch/arm/mach-omap1/gpio16xx.c create mode 100644 arch/arm/mach-omap1/gpio7xx.c create mode 100644 arch/arm/mach-omap2/gpio.c -- 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
