Tony Lindgren ec0daae685 gpio: omap: Add level wakeup handling for omap4 based SoCs ... I noticed that unlike omap2 and 3 based SoCs, omap4 based SoCs keep the GPIO clocks enabled for GPIO level interrupts with wakeup enabled. This blocks deeper idle states as the whole domain will stay busy. The GPIO functional clock seems to stay enabled if the wakeup register is enabled and a level interrupt is triggered. In that case the only way to have the GPIO module idle is to reset it. It is possible this has gone unnoticed with OSWR (Open SWitch Retention) and off mode during idle resetting GPIO context most GPIO instances in the earlier Android trees for example. Looks like the way to deal with this is to have omap4 based SoCs only set wake for the duration of idle for level interrupts, and clear level registers for the idle. With level interrupts we can do this as the level interrupt from device will be still there on resume. I've taken the long path to fixing this to avoid yet more hard to read code. I've set up a quirks flag, and a struct for function pointers so we can use these to clean up other quirk handling easier in the later patches. The current level quirk handling is moved to the new functions.
