Subject: regulator: Fix the logic of tps65910_get_mode
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=585993932ccc44ab6a8c6dc590a2f3d6b2facb41;p=linux-beck.git

regulator: Fix the logic of tps65910_get_mode

We actually clear LDO_ST_ON_BIT for standby mode in tps65910_set_mode.
Fix the logic in tps65910_get_mode.

Supply state (EEPROM bits):
ST[1:0] = 00 : Off
ST[1:0] = 01 : On high power (ACTIVE)
ST[1:0] = 10 : Off
ST[1:0] = 11 : On low power (SLEEP)
