2013-04-04pinctrl: gpio: vt8500: Add pincontrol driver for arch-vt8500Tony Prisk1-0/+1
This patch adds support for the GPIO/pinmux controller found on the VIA VT8500 and Wondermedia WM8xxx-series SoCs. Each pin within the controller is capable of operating as a GPIO or as an alternate function. The pins are numbered according to their control bank/bit so that if new pins are added, the existing numbering is maintained. All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and WM8850.

2013-01-22ARM: remove redundant 'select GENERIC_GPIO'Shawn Guo1-1/+0
In drivers/gpio/Kcong, ARCH_REQUIRE_GPIOLIB selects GPIOLIB which in turn selects GENERIC_GPIO. So GENERIC_GPIO will be selected automatically for those platforms that select ARCH_REQUIRE_GPIOLIB. Remove the redundant 'select GENERIC_GPIO' for platforms that already select ARCH_REQUIRE_GPIOLIB at either mach or plat level.

2013-01-15timer: vt8500: Convert vt8500 to use CLKSRC_OFTony Prisk1-0/+1
This patch converts arch-vt8500 to make use of CLKSRC_OF. Doing so removes the need for include/linux/vt8500_timer.h as vt8500_timer_init no longer needs to be visible outside vt8500_timer.c Signed-off-by: Tony Prisk <linux@prisktech.co.nz> Reviewed-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Olof Johansson <olof@lixom.net>

2011-01-25ARM: 6597/1: Add basic architecture support for VIA/WonderMedia 85xx SoC'sAlexey Charkov1-0/+73
This adds support for the family of Systems-on-Chip produced initially by VIA and now its subsidiary WonderMedia that have recently become widespread in lower-end Chinese ARM-based tablets and netbooks. Support is included for both VT8500 and WM8505, selectable by a configuration switch at kernel build time. Included are basic machine initialization files, register and interrupt definitions, support for the on-chip interrupt controller, high-precision OS timer, GPIO lines, necessary macros for early debug, pulse-width-modulated outputs control, as well as platform device configurations for the specific drivers implemented elsewhere.
