This patch series contains patches which fixes wrong APIs usage in atomic context on RT-kernel. The final goal is to make TI OMAP GPIO driver compatible with -RT kernel as much as possible.
Patch 1: required to be compatible with -RT kernel, because PM runtime's irq_safe mode is incompatible with -RT. Patch 2: This patch converts TI OMAP GPIO driver to use generic irq handler instead of chained IRQ handler. This way OMAP GPIO driver will be compatible with RT-kernel where it will be forced thread IRQ handler while in non-RT kernel it still will be executed in HW IRQ context. Boot, basic gpio functionality tested on: dra7-evm, BeagleBone(white), am43xx-gpevm, am437x-sk Manually tested on dra7-evm including suspend/resume and wakeup.
