Documentation: gpio: guidelines for bindings

2014-10-30T15:41:47Z

Now that ACPI supports named GPIO properties, either through ACPI 5.1 or the per-driver ACPI GPIO mappings, we can be more narrow about the way GPIOs should be specified in Device Tree bindings. This patch updates the GPIO DT bindings documentation to highlight the following rules for new GPIO bindings: - All new bindings must have a meaningful name (e.g. the "gpios" property must not be used) - The only suffix allowed is "-gpios", no matter the number of descriptors in the property - GPIOs can only be grouped under the same property when they serve the same purpose, a case that should remain exceptional (e.g. bit-banged data lines).

Documentation: dts: add bindings for Vybrid GPIO/PORT module

2014-10-24T12:22:27Z

The Vybrid SoC device tree (vf610.dtsi) used this bindings since its initial commit in May 2013. However, a proper gpiolib driver was missing so far. With the addition of the gpiolib driver, the bindings proved to be useful and complete, hence a good time to add the documentation.

gpio: syscon: reuse for keystone 2 socs

2014-09-16T21:42:16Z

On Keystone SOCs, ARM host can send interrupts to DSP cores using the DSP GPIO controller IP. Each DSP GPIO controller provides 28 IRQ signals for each DSP core. This is one of the component used by the IPC mechanism used on Keystone SOCs. Keystone 2 DSP GPIO controller has specific features: - each GPIO can be configured only as output pin; - setting GPIO value to 1 causes IRQ generation on target DSP core; - reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still pending. This patch updates gpio-syscon driver to be reused by Keystone 2 SoCs, because the Keystone 2 DSP GPIO controller is controlled through Syscon devices and, as requested by Linus Walleij, such kind of GPIO controllers should be integrated with drivers/gpio/gpio-syscon.c driver.
