It seems that all omap3 boards using this are pretty much wired the same way. > So I have nothing against having common files, but shouldn't this be > named something more specific?

Yeah let's use omap3-panel-sharp-ls037v7dw01.dtsi. Looking at the legacy board files that should cover quite a few of them. I guess it might also work on 2430sdp, but let's assume omap3 for now. > > +/ { > > + aliases { > > + display0 = &lcd0; > > + }; > > + > > + backlight0: backlight { > > + compatible = "gpio-backlight"; > > + }; > > + > > + /* 3.3V GPIO controlled regulator for LCD_ENVDD */ > > + lcd_3v3: regulator-lcd-3v3 { > > + compatible = "regulator-fixed"; > > + regulator-name = "lcd_3v3"; > > + regulator-min-microvolt = <3300000>; > > + regulator-max-microvolt = <3300000>; > > + startup-delay-us = <70000>; > > + regulator-always-on; > > Why always-on? Oops, yeah that should not be there. The GPIO is board specific.
