X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7a53133ac4b5b26924146bc1b044594894ccc400;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: qcom: sm7225-fairphone-fp4: Enable CCI pull-up

Enable vreg_l6p, which is the voltage source for the pull-up resistor of
the CCI busses.

This ensures that I2C communication works as expected.
