Subject: arm64: dts: qcom: glymur-crd: Enable keyboard, trackpad and touchscreen
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e6bf559f7eb92858795b7aaecf67ad98dbb43a49;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: qcom: glymur-crd: Enable keyboard, trackpad and touchscreen

On CRD, the keyboard, trackpad and touchscreen are connected over I2C
and all share a 3.3V regulator.

So describe the regulator and each input device along with their
pinctrl states.
