* dm: gpio: introduce 74x164 driverPeng Fan2016-05-171-0/+8
| | | | | | | | | | | | | | | | | | | | Introduce driver to support "fairchild,74hc595" devices. 1. Take linux drivers/drivers/gpio/gpio-74x164.c as reference. 2. Following the naming used in Linux driver with gen_7x164 as the prefix. 3. Enable CONFIG_DM_74X164 to use this driver. 4. Follow Documentation/devicetree/bindings/gpio/gpio-74x164.txt to add device nodes 5. Tested on i.MX6 UltraLite with 74LV595 using gpio command and oscillograph.

* dm: gpio: pca953x: introduce driver model support for pca953xPeng Fan2016-05-171-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new driver that supports driver model for pca953x. The pca953x chips are used as I2C I/O expanders. This driver is designed to support the following chips: " 4 bits: pca9536, pca9537 8 bits: max7310, max7315, pca6107, pca9534, pca9538, pca9554, pca9556, pca9557, pca9574, tca6408, xra1202 16 bits: max7312, max7313, pca9535, pca9539, pca9555, pca9575, tca6416 24 bits: tca6424 40 bits: pca9505, pca9698 " But for now this driver only supports max 24 bits and pca953x compatible chips. pca957x compatible chips are not supported now. These can be addressed when we need to add such support for the different chips. This driver has been tested on i.MX6 SoloX Sabreauto board with max7310 i2c expander using gpio command as following: =>gpio status -a Bank gpio@30_: gpio@30_0: input: 1 [ ] => dm tree: i2c [ ] | | `-- i2c@021a8000 gpio [ ] | | |-- gpio@30 gpio [ ] | | `-- gpio@32 Signed-off-by: Peng Fan <van.freenix@gmail.com> Cc: Simon Glass <sjg@chromium.org> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Wenyou Yang <wenyou.yang@atmel.com> Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Cc: Purna Chandra Mandal <purna.mandal@microchip.com> Cc: Thomas Chou <thomas@wytron.com.tw> Cc: Bhuvanchandra DV <bhuvanchandra.dv@toradex.com> Cc: Andrea Scian <andrea.scian@dave.eu> Cc: Michal Simek <michal.simek@xilinx.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@nxp.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Michal Simek <michal.simek@xilinx.com> #on ZynqMP zcu102

* gpio: Add DM GPIO driver for Marvell MVEBUStefan Roese2016-03-241-0/+7
| | | | | | | | | | | | | | | | | | This patch adds a DM GPIO driver for the Marvell MVEBU SoCs. There are other non-DM drivers that might be used on these platforms. But this patch creates a new DM driver. Which will be used by all Armada XP/38x boards. Other MVEBU SoC (Kirkwood / Orion) may follow once they support DM as well.
