dt-bindings: gpio: aspeed: Update documentation with ast2600 controllers

2019-09-10T17:29:57+00:00

The ast2600 is a new generation of SoC from ASPEED. Similarly to the ast2400 and ast2500, it has a GPIO controller for it's 3.3V GPIO pins. Additionally, it has a GPIO controller for 36 1.8V GPIO pins. We use the ngpio property to differentiate between these controllers.

dt-bindings: gpio: document the new pull-up/pull-down flags

2019-02-13T08:07:43+00:00

This commit extends the flags that can be used in GPIO specifiers to indicate if a pull-up resistor or pull-down resistor should be enabled. While some pinctrl DT bindings already offer the capability of configuring pull-up/pull-down resistors at the pin level, a number of simple GPIO controllers don't have any pinmuxing capability, and therefore do not rely on the pinctrl DT bindings. Such simple GPIO controllers however sometimes allow to configure pull-up and pull-down resistors on a per-pin basis, and whether such resistors should be enabled or not is a highly board-specific HW characteristic. By using two additional bits of the GPIO flag specifier, we can easily allow the Device Tree to describe which GPIOs should have their pull-up or pull-down resistors enabled. Even though the two options are mutually exclusive, we still need two bits to encode at least three states: no pull-up/pull-down, pull-up, pull-down.
