pinctrl: st: Fix irqmux handler

2014-07-15T18:55:15Z

st_gpio_irqmux_handler() reads the status register to find out which banks inside the controller have pending IRQs. For each banks having pending IRQs, it calls the corresponding handler. Problem is that current code restricts the number of possible banks inside the controller to ST_GPIO_PINS_PER_BANK. This define represents the number of pins inside a bank, so it shouldn't be used here. On STiH407, PIO_FRONT0 controller has 10 banks, so IRQs pending in the two last banks (PIO18 & PIO19) aren't handled. This patch replace ST_GPIO_PINS_PER_BANK by the number of banks inside the controller.

pinctrl: berlin: fix an error code in berlin_pinctrl_probe()

We are returning success here because PTR_ERR(NULL) is zero. We should be returning -ENODEV. Fixes: 3de68d331c24 ('pinctrl: berlin: add the core pinctrl driver for Marvell Berlin SoCs') Signed-off-by: Dan Carpenter Acked-by: Sebastian Hesselbarth Signed-off-by: Linus Walleij

Merge tag 'pinctrl-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl into next

2014-06-03T18:20:32Z

Pull pin control changes from Linus Walleij: "This is the bulk of pin control changes for the v3.16 development cycle: - Antoine Tenart made the get_group_pins() vtable entry optional. - Antoine also provides an entirely new driver for the Marvell Berlin SoC. This is unrelated to the existing MVEBU hardware driver and warrants its own separate driver. - reflected from the GPIO subsystem there is a number of refactorings to make pin control drivers with gpiochips use the new gpiolib irqchip helpers. The following drivers were converted to use the new infrastructure: * ST Microelectronics STiH416 and friends * The Atmel AT91 * The CSR SiRF (Prima2) * The Qualcomm MSM series - massive improvements in the Qualcomm MSM driver from Bjorn Andersson, Andy Gross and Kumar Gala. Among those new support for the IPQ8064 and MSM8x74 SoC variants. - support for the Freescale i.MX6 SoloX SoC variant. - massive improvements in the Allwinner sunxi driver from Boris Brezillon, Maxime Ripard and Chen-Yu Tsai. - Renesas PFC updates from Laurent Pinchart, Kuninori Morimoto, Wolfram Sang and Magnus Damm. - Cleanups and refactorings of the nVidia Tegra driver from Stepgen Warren. - the Exynos driver now supports the Exynos3250 SoC. - Intel BayTrail updates from Jin Yao, Mika Westerberg. - the MVEBU driver now supports the Orion5x SoC variants, which is part of the effort of getting rid of the old Marvell kludges in arch/arm/mach-orion5x - Rockchip driver updates from Heiko Stuebner. - a ton of cleanups and janitorial patches from Axel Lin. - some minor fixes and improvements here and there" * tag 'pinctrl-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (93 commits) pinctrl: sirf: fix a bad conflict resolution pinctrl: msm: Add more MSM8X74 pin definitions pinctrl: qcom: ipq8064: Fix naming convention pinctrl: msm: Add missing sdc1 and sdc3 groups pinctrl: sirf: switch to using allocated state container pinctrl: Enable "power-source" to be extracted from DT files pinctrl: sunxi: create irq/pin mapping during init pinctrl: pinconf-generic: Use kmemdup instead of kmalloc + memcpy pinctrl: berlin: Use devm_ioremap_resource() pinctrl: sirf: fix typo for GPIO bank number pinctrl: sunxi: depend on RESET_CONTROLLER pinctrl: sunxi: fix pin numbers passed to register offset helpers pinctrl: add pinctrl driver for imx6sx pinctrl/at91: Fix lockup when IRQ on PIOC and PIOD occurs pinctrl: msm: switch to using generic GPIO irqchip helpers pinctrl: sunxi: Fix multiple registration issue pinctrl: sunxi: Fix recursive dependency pinctrl: berlin: add the BG2CD pinctrl driver pinctrl: berlin: add the BG2 pinctrl driver pinctrl: berlin: add the BG2Q pinctrl driver ...

pinctrl: sirf: fix a bad conflict resolution

Commit 294d1351ff47726f0f110b88e816cbafe89512fb "pinctrl: sirf: switch to using allocated state container" caused a build conflict due to a bad conflict resolution when cherry-picking the patch. Fix it up. Cc: Barry Song Signed-off-by: Linus Walleij

pinctrl: msm: Add more MSM8X74 pin definitions

pinctrl: sirf: switch to using allocated state container

2014-05-28T08:42:04Z

This rewrites the SIRF pinctrl driver to allocate a state container for the GPIO chip, just as is done for the pin controller, and use the gpiochip_add_pin_range() to add the range from the gpiochip side rather than adding the range from the pinctrl side. All resulting changes are done in order to pass around a state container rather than refer to a static global object. Acked-by: Barry Song Signed-off-by: Linus Walleij
