Merge tag 'vt8500/pinctrl' of git://server.prisktech.co.nz/git/linuxwmt into next/drivers
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.
