Subject: rockchip: rk3399-puma: Restore correct VDD_LOG supply.
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=1621afc84f8a109cfdb98c9e370c355289e07870;p=u-boot.git

rockchip: rk3399-puma: Restore correct VDD_LOG supply.

A commit from last year re-imported the DTS files form the upstream kernel.
By doing so the VDD_LOG regulator in the board's DTS was dropped.
Let's restore this, but move it into the u-boot overlay to prevent this
issue in the future.
