Hello, This series rework the sunxi pinctrl driver to support the PL and PM pins available on the A31 SoC, which are controlled using the R_PIO block. This series add support for multi pin controller which was previously impossible for several reasons: 1) the pinctrl instance was registering a static instance of the gpio chip, which means, in case you were probing 2 devices, the gpio chip was added twice to the gpiochip list 2) the base pin of the gpio chip was always set to 0, and thus the 2 gpiochip pin numbers were overlapping I still haven't reworked the interrupt part (to handle the "per bank interrupt" instead of the "one interrupt for the whole gpio" chip approach), but this will be part of another series. Best Regards, Boris Changes since v1: - rework the pinctrl driver to support multiple pin controller instances - removed reset and clock gate patches from the series - removed A31 DT modifications from the series (we need to get the PRCM reset and clk drivers before being able to declare the r_pio node, and we're still discussing how this should be implemented) Boris BREZILLON (5): pinctrl: sunxi: add PL and PM pin definitions pinctrl: sunxi: support multiple pin controller pinctrl: sunxi: define A31 R_PIO pin functions pinctrl: sunxi: add reset control support ARM: sunxi: update the default ARCH_NR_GPIO for sunxi arch .../bindings/pinctrl/allwinner,sunxi-pinctrl.txt | 1 + arch/arm/Kconfig | 2 +- drivers/pinctrl/pinctrl-sunxi-pins.h | 74 ++++++++++++++++++++++ drivers/pinctrl/pinctrl-sunxi.c | 40 +++++++----- drivers/pinctrl/pinctrl-sunxi.h | 69 ++++++++++++++++++++ 5 files changed, 169 insertions(+), 17 deletions(-) -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
