dm: gpio: Add methods for open drain setting

2016-06-04T05:13:52Z

Certain GPIO devices have the capability to switch their GPIOs into open-drain mode, that is, instead of actively driving the output (Push-pull output), the pin is connected to the collector (for a NPN transistor) or the drain (for a MOSFET) of a transistor, respectively. The pin then either forms an open circuit or a connection to ground, depending on the state of the transistor. This patch adds functions to the GPIO uclass to switch GPIOs to open-drain mode on devices that support it. Signed-off-by: Mario Six Reviewed-by: Simon Glass Reviewed-by: York Sun

dm: gpio: Add driver for MPC85XX GPIO controller

2016-06-04T05:13:24Z

This patch adds a driver for the built-in GPIO controller of the MPC85XX SoC (probably supporting other PowerQUICC III SoCs as well). Each GPIO bank is identified by its own entry in the device tree, i.e. gpio-controller@fc00 { #gpio-cells = <2>; compatible = "fsl,pq3-gpio"; reg = <0xfc00 0x100> } By default, each bank is assumed to have 32 GPIOs, but the ngpios setting is honored, so the number of GPIOs for each bank in configurable to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of the P1022 SoC). The usual functions of GPIO drivers (setting input/output mode and output value setting) are supported. The driver has been tested on MPC85XX, but it is likely that other PowerQUICC III devices will work as well. Signed-off-by: Mario Six Reviewed-by: Simon Glass Reviewed-by: York Sun

The MXS certainly does not support any sort of networking in GPIO code, remove the netdev.h header. Signed-off-by: Marek Vasut Cc: Tom Rini Cc: Simon Glass Reviewed-by: Simon Glass

gpio: add Tegra186 GPIO driver

2016-05-31T16:54:24Z

Tegra186's GPIO controller register layout is significantly different from previous chips, so add a new driver for it. In fact, there are two different GPIO controllers in Tegra186 that share a similar register layout, but very different port mapping. This driver covers both. The DT binding is already present in the Linux kernel (in linux-next via the Tegra tree so far). Signed-off-by: Stephen Warren Reviewed-by: Simon Glass # v1 Signed-off-by: Tom Warren

ARM: tegra: convert CONFIG_TEGRA_GPIO to Kconfig

2016-05-31T16:53:57Z

Future chips will contain different GPIO HW. This change will enable future SoC support to select the appropriate GPIO driver for their HW, in a future-looking fashion, using Kconfig. TEGRA_GPIO is not simply selected by TEGRA_COMMON (even though all current Tegra chips used this GPIO HW) to simplify the later addition of support for Tegra SoCs that use different GPIO HW.
