Subject: regulator: rk8xx: Return correct voltage for switchout converters
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=bb657ffdd688dc08073734a402914ec0a8492d53;p=u-boot.git

regulator: rk8xx: Return correct voltage for switchout converters

The voltage value for switchout converters is always reported as 0 uV.
When the switch is enabled, it's voltage is same as input supply.

Fix this by implementing get_value for switchout converters.
