Enable Display Subsystem with Novatek NT36672E Panel on qcm6490 idp platform. Signed-off-by: Ritesh Kumar <quic_riteshk@quicinc.com> --- v2: Fixed review comments from Dmitry and Konrad - moved pinctrl-names after pinctrl-0 property. - removed gpu disablement change after validating gpu. Rebased the patch - rebased the patch to resolve conflicts. v3: Fixed review comments from Dmitry - renamed panel supply to regulator-lcd-disp-bias. - moved backlight as per sort order. --- arch/arm64/boot/dts/qcom/qcm6490-idp.dts | 92 ++++++++++++++++++++++++ 1 file changed, 92 insertions(+)
