The string defined in > dtschema is 'melfas,mip4_ts', which implies that it's a MIP4 *touchscreen* > by MELFAS. I see that there are 2 dts(i) files which use the compatible "melfas,mip4_ts", as discovered from a simple grep in arch/. They are: - arm64/qcom/msm8916-lg-m216.dts - arm64/mediatek/mt8173-elm-hana.dtsi Is it possible to change all references of the compatible to something more generic, such as "melfas,mip4"?
