OK, we will change the node name to ethdr like in dts like this: ethdr0: ethdr@1c114000 { ... }
Is "ethdr" a generic name? Is it an abbreviation of "EnergyTrace™ High Dynamic Range"? If yes, it also looks specific to Texas Instruments...
Best regards, Krzysztof
That's mediatek-drm, and this refers to the HDR block in the display IP...
Though, I have no idea of what "ET" stands for in "ETHDR", so, it would be definitely nice if MediaTek can write the meaning in the description, like
description: ETHDR (E??? T??? High Dynamic Range) is designed for HDR video and ...blah

Hello Krzysztof and Angelo,
"ET" is actually meaningless. ET is one of mediatek departments and it's where the engine from. Therefore, I think we will add description like this:
ETHDR (ET High Dynamic Range) is a MediaTek internal HDR engine and designed for HDR video...
