Subject: [PATCH 13/54] ARM: dts: rockchip: Add dvs-gpios to
|
||
|
|
rk3288-veyron-jerry
|
||
|
|
|
||
|
|
When the rk3288-jerry device tree was first submitted we left out the
|
||
|
|
dvs-gpios because I pointed out that the property "dvs-gpios" wasn't
|
||
|
|
yet supported upstream [1]. Soon after that the property was added in
|
||
|
|
commit bad47ad2eef3 ("regulator: rk808: fixed the overshoot when
|
||
|
|
adjust voltage"). ...but we forgot to go back and add the property to
|
||
|
|
the jerry device tree file. Let's do so now.
|
||
|
|
|
||
|
|
NOTE: without this patch, jerry is likely still stable (thanks to the
|
||
|
|
fallback of making many small jumps in the rk808 regulator code) but
|
||
|
|
it'll take quite a bit longer to make voltage transitions.
