[PATCH 1/1] ARM: OMAP2+: Fix omap3 off idle power consumption creeping up

2015-04-21 Thread Tony Lindgren
If we use a combination of VMODE and I2C4 for retention modes, eventually the off idle power consumption will creep up by about 23mW, even during off mode with I2C4 always staying enabled. Looks like the only way to fix the extra power consumption is to disable I2C4 usage by setting SEL_VMODE for
