Subject: arm64: dts: qcom: milos-fairphone-fp6: Add Hall Effect sensor
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9fc67d20c9a6c6d6fe2f859672ead18898d4c45a;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: qcom: milos-fairphone-fp6: Add Hall Effect sensor

Add a node for the Hall Effect sensor, used to detect whether the Flip
Cover is closed or not.

The sensor is powered through vreg_l10b, so let's put a
regulator-always-on on that to make sure the sensor gets power.
