7 years agoregulator: max77663: Add safe voltage scaling step
Min-wuk Lee [Fri, 4 Nov 2011 07:46:24 +0000]
regulator: max77663: Add safe voltage scaling step

The MAX77663 PMU has under-shooting issue when voltage down scaling
on SD power rails until revision 3. So if revision is less than rev3,
set safe_down_uV for stable down scaling.

Colin Cross [Wed, 24 Aug 2011 00:43:54 +0000]
ARM: tegra: sleep: flush tlbs when exiting wfi

tegra_sleep_wfi disables coherency to prepare for possibly
resetting the cpu.  If an interrupt is received, it exits
wfi and re-enables coherency, but it was not flushing the
tlbs or the branch predictor array, which could have been
updated by broadcast tlb operations that were ignored.
Flush the tlbs and branch predictor array when exiting.
