From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxx> Hi Linus W, This series of patches add interrupt controller support to ST pinctrl driver. ST pin controller GPIO bank can have one of the two possible types of interrupt-wirings. First type is via irqmux, single interrupt is used by multiple gpio banks. This reduces number of interrupts numbers required by pin controller. All these gpio banks belong to a single pin controller. Second type has a dedicated interrupt per gpio bank. Interrupt number usage is very high in this case. This patch adds support to both these wirings. Also, ST pin controller hardware only supports level triggered interrupts. However for drivers like gpio keypad requires edge trigger interrupt support, so one of the patch adds edge trigger interrupt support in software by using the existing level trigger support in hardware. Patch 01: Is a minor typo fix. Patch 02: Adds level interrupt support to pin controller. Patch 03: Adds software edge trigger support. Patch 04,05 : Updates STiH415, STiH416 dts files for interrupt support. As Patch-01 only has a typo fix I did not move it out of this series. Comments? Thanks, srini Srinivas Kandagatla (5): pinctrl: st: Fix a typo in probe pinctrl: st: Add Interrupt support. pinctrl: st: Add software edge trigger interrupt support.
