From Tony Prisk <linux@prisktech.co.nz>: arm: vt8500: Add pinctrl driver for arch-vt8500 This series adds support for the pinctrl/gpio module on all arch-vt8500 supported SoCs. As part of the review process, some tidy up is also done to drivers/of/base.c to remove some code that is being constantly duplicated. Also, a patch for the bcm2835 pinctrl driver is included to take advantage of the new of/base.c code. * tag 'vt8500/pinctrl' of git://server.prisktech.co.nz/git/linuxwmt: (606 commits) pinctrl: bcm2835: make use of of_property_read_u32_index() gpio: vt8500: Remove arch-vt8500 gpio driver arm: vt8500: Remove gpio devicetree nodes arm: dts: vt8500: Update Wondermedia SoC dtsi files for pinctrl driver pinctrl: gpio: vt8500: Add pincontrol driver for arch-vt8500 arm: vt8500: Increase available GPIOs on arch-vt8500 of: Remove duplicated code for validating property and value of: Add support for reading a u32 from a multi-value property.

2013-04-03gpio: Renesas R-Car GPIO driver V3Magnus Damm3-0/+380
This patch is V3 of a GPIO driver for the R-Car series of SoCs from Renesas. This driver is designed to be reusable between multiple SoCs that share the same basic building block, but so far it has only been used on R-Car H1 (r8a7779). Each driver instance handles 32 GPIOs with individually maskable IRQs. The driver operates on a single I/O memory range and the 32 GPIOs are hooked up a single interrupt. In the case of R-Car H1 either external IRQ pins or GPIOs with interrupts can be used for on-board interupts. For external IRQs 4 pins are supported, and in the case of GPIO there are 202 GPIOS as 202 interrupts hooked up via 6 driver instances and to the GIC and the Cortex-A9 Quad. At this point this driver is interfacing as a regular platform device driver. In the future DT support will be submitted as an incremental feature patch.

2013-03-08gpio: mvebu: Add clk support to prevent lockupAndrew Lunn1-0/+7
The kirkwood SoC GPIO cores use the runit clock. Add code to clk_prepare_enable() runit, otherwise there is a danger of locking up the SoC by accessing the GPIO registers when runit clock is not ticking.
