X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=22b154365fbc096a46d936ec1f462ef8b9bd1f05;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git Merge tag 'renesas-pinctrl-for-linus' of git://git./linux/kernel/git/arm/arm-soc Pull ARM SoC pinctrl changes for Renesas from Olof Johansson: "This is yet another driver change, which is split out just because of its size. As already in 3.9, a lot of changes are going on here, as the shmobile platform gets converted from its own pin control API to the generic drivers/pinctrl subsystem. Based on agreements with Paul Mundt, we are merging the sh-arch-side changes here as well" * tag 'renesas-pinctrl-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (142 commits) ARM: shmobile: r8a7779: Remove INTC function GPIOs ARM: shmobile: r8a7779: Remove LBSC function GPIOs ARM: shmobile: r8a7779: Remove USB function GPIOs ARM: shmobile: r8a7779: Remove HSPI function GPIOs ARM: shmobile: r8a7779: Remove SCIF function GPIOs ARM: shmobile: r8a7779: Remove SDHI and MMCIF function GPIOs ARM: shmobile: r8a7779: Remove DU function GPIOs ARM: shmobile: r8a7779: Remove DU1_DOTCLKOUT1 GPIO ARM: shmobile: r8a7740: Remove SDHI and MMCIF function GPIOs ARM: shmobile: r8a7740: Remove LCD0 and LCD1 function GPIOs ARM: shmobile: sh73a0: Remove IrDA function GPIOs ARM: shmobile: sh73a0: Remove USB function GPIOs ARM: shmobile: sh73a0: Remove BSC function GPIOs ARM: shmobile: sh73a0: Remove KEYSC function GPIOs ARM: shmobile: sh73a0: Remove pull-up function GPIOS ARM: shmobile: sh73a0: Remove FSI function GPIOs ARM: shmobile: sh73a0: Remove I2C function GPIOs ARM: shmobile: sh73a0: Remove SCIFA and SCIFB function GPIOs ARM: shmobile: sh73a0: Remove LCDC and LCDC2 function GPIOs ARM: shmobile: sh7372: Remove SDHI and MMCIF function GPIOs ... --- 22b154365fbc096a46d936ec1f462ef8b9bd1f05 diff --cc drivers/pinctrl/sh-pfc/pfc-sh73a0.c index 6f15c03077a0,cde4387edce1..587f7772abf2 --- a/drivers/pinctrl/sh-pfc/pfc-sh73a0.c +++ b/drivers/pinctrl/sh-pfc/pfc-sh73a0.c @@@ -2733,60 -3849,116 +3849,116 @@@ static const struct pinmux_data_reg pin { }, };
