pinctrl: exynos: Lock GPIOs as interrupts when used as EINTs

2014-08-21T12:24:29Z

Currently after configuring a GPIO pin as an interrupt related pinmux registers are changed, but there is no protection from calling gpio_direction_*() in a badly written driver, which would cause the same pinmux register to be reconfigured for regular input/output and this disabling interrupt capability of the pin. This patch addresses this issue by moving pinmux reconfiguration to .irq_{request,release}_resources() callback of irq_chip and calling gpio_lock_as_irq() helper to prevent reconfiguration of pin direction. Setting up a GPIO interrupt on Samsung SoCs is a two-step operation - in addition to trigger configuration in a dedicated register, the pinmux must be also reconfigured to GPIO interrupt, which is a different function than normal GPIO input, although I/O-wise they both behave in the same way and gpio_get_value() can be used on a pin configured as IRQ as well. Such design implies subtleties such as gpio_direction_input() not having to fail if a pin is already configured as an interrupt nor change the configuration to normal input. But the FLAG_USED_AS_IRQ set in gpiolib by gpio_lock_as_irq() is only used to check that gpio_direction_output() is not called, it's not used to prevent gpio_direction_input() to be called. So this is not a complete solution for Samsung SoCs but it's definitely a move in the right direction.

pinctrl: pinctrl-at91.c: fix decimal printf format specifiers prefixed with 0x

2014-08-17T14:15:44Z

The prefix suggests the number should be printed in hex, so use the %x specifier to do that. Found by using regex suggested by Joe Perches. Signed-off-by: Hans Wennborg Acked-by: Alexandre Belloni Signed-off-by: Linus Walleij

pinctrl: rockchip: fix rk3288 gpio0 configuration

2014-08-17T14:15:43Z

On rk3288, for gpio bank 0, the registers which configure pull-up, iomux, and drive strength don't implement the enable bits in the upper half of the register, unlike the other gpio configuration registers, and so the kernel must perform a read-modify-write of the register to update a particular gpio in that bank. The current code is actually clobbering the contents of the register, so this fixes it by using regmap_update_bits and masking out only the bits which require updating. In the case of bank0 on rk3288 the upper enable bits will just get ignored, and the other configurations won't get clobbered.

I had made last-minute changes before submitting the patch "sh-pfc: r8a7791: add CAN pin groups"; now I'm seeing that they weren't complete: I had missed update to the pin group names in pin[01]_groups[].

Pull ARM SoC driver changes from Olof Johansson: "A handful of driver-related changes. We've had a bunch of them going in through other branches as well, so it's only a part of what we really have this release. Larger pieces are: - Removal of a now unused PWM driver for atmel [ This includes AVR32 changes that have been appropriately acked ] - Performance counter support for the arm CCN interconnect - OMAP mailbox driver cleanups and consolidation - PCI and SATA PHY drivers for SPEAr 13xx platforms - Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to better model regulators/power" Note: this merge also fixes up the semantic conflict with the new calling convention for devm_phy_create(), see commit f0ed817638b5 ("phy: core: Let node ptr of PHY point to PHY and not of PHY provider") that came in through Greg's USB tree.

Pull ARM SoC device-tree changes from Olof Johansson: "Unlike the board branch, this keeps having large sets of changes for every release, but that's quite expected and is so far working well. Most of this is plumbing for various device bindings and new platforms, but there's also a bit of cleanup and code removal for things that are moved from platform code to DT contents (some OMAP clock code in particular). There's also a pinctrl driver for tegra here (appropriately acked), that's introduced this way to make it more bisectable. I'm happy to say that there were no conflicts at all with this branch this release, which means that changes are flowing through our tree as expected instead of merged through driver maintainers (or at least not done with conflicts). There are several new boards added, and a couple of SoCs. In no particular order: - Rockchip RK3288 SoC support, including DTS for a dev board that they have seeded with some community developers. - Better support for Hardkernel Exynos4-based ODROID boards. - CCF conversions (and dtsi contents) for several Renesas platforms. - Gumstix Pepper (TI AM335x) board support - TI eval board support for AM437x - Allwinner A23 SoC, very similar to existing ones which mostly has resulted in DT changes for support. Also includes support for an Ippo tablet with the chipset. - Allwinner A31 Hummingbird board support, not to be confused with the SolidRun i.MX-based Hummingboard. - Tegra30 Apalis board support" * tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (334 commits) ARM: dts: Enable USB host0 (EHCI) on rk3288-evb ARM: dts: add rk3288 ehci usb devices ARM: dts: Turn on USB host vbus on rk3288-evb ARM: tegra: apalis t30: fix device tree compatible node ARM: tegra: paz00: Fix some indentation inconsistencies ARM: zynq: DT: Clarify Xilinx Zynq platform ARM: dts: rockchip: add watchdog node ARM: dts: rockchip: remove pinctrl setting from radxarock uart2 ARM: dts: Add missing pinctrl for uart0/1 for exynos3250 ARM: dts: Remove duplicate 'interrput-parent' property for exynos3250 ARM: dts: Add TMU dt node to monitor the temperature for exynos3250 ARM: dts: Specify MAX77686 pmic interrupt for exynos5250-smdk5250 ARM: dts: cypress,cyapa trackpad is exynos5250-Snow only ARM: dts: max77686 is exynos5250-snow only ARM: zynq: DT: Remove DMA from board DTs ARM: zynq: DT: Add CAN node ARM: EXYNOS: Add exynos5260 PMU compatible string to DT match table ARM: dts: Add PMU DT node for exynos5260 SoC ARM: EXYNOS: Add support for Exynos5410 PMU ARM: dts: Add PMU to exynos5410 ...
