Subject: dt-bindings: pinctrl: mediatek: deprecate custom drive strength property
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=000602e6d9b0fe3d441234d28c8a7297fd783727;p=linux.git

dt-bindings: pinctrl: mediatek: deprecate custom drive strength property

Deprecate mediatek,drive-strength-adv which shall not exist, that was an
unnecessary property that leaked upstream from downstream kernels and
there's no reason to use it.

The generic property drive-strength-microamp should be used instead.
