Since the SDIO irq is level triggered, I have to disable the IRQ in the handler otherwise it is called infinitely. Did some other minor changes see below. v8 - rebased on top of Tony Lindgren changes - improved changelog describing the earlier work - improved wakeup irq setup - works on am3730 es platform now - my changes on top: - compile tested with #undef CONFIG_OF - disable wake_irq in handler to prevent infinite loop - fixed typo and added comment about wake-irq v7 - rebase on 3.14.0-rc3-49726-g77e15ec - split omap_hsmmc_pin_init due to regression on omap-3730 platform v6 - rebase on Linux 3.13-rc3 - reformatting debugfs v5 - fix compile error introduced by last minute one line fix v4: - switch to interrupts-extended format - drop ti,swakeup-missing flag convert to comaptible section v3: - removed gpio_irq from platform_data v2: - incorparated changes as suggested by reviewers - simplified workaround for am335x, gpio will now only wake the module from runtime suspend, not handle the sdio irq itself Andreas Fenkart (3): mmc: omap_hsmmc: Enable SDIO interrupt mmc: omap_hsmmc: Pin remux workaround to support SDIO interrupt on AM335x mmc: omap_hsmmc: Extend debugfs for SDIO IRQ, GPIO and pinmux. .../devicetree/bindings/mmc/ti-omap-hsmmc.txt | 50 +++ drivers/mmc/host/omap_hsmmc.c | 337 ++++++++++++++++++-- include/linux/platform_data/mmc-omap.h | 1 + 3 files changed, 363 insertions(+), 25 deletions(-) -- 1.7.10.4
