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.
