Subject: dt-bindings: clock: qcom: Allow VDD_GFX supply to GX
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e60b95d2b68724baaacc5f7d91cfc3060811a1c1;p=linux.git

dt-bindings: clock: qcom: Allow VDD_GFX supply to GX

In some designs the SoC's VDD_GFX pads are supplied by an external
regulator, rather than a power-domain. Allow this to be described in the
GPU clock controller binding.
