You need custom binding anyway. Hi Krzysztof, I really don't understand the reason behind having a custom binding for such device. It even doesn't have a driver and purely rely on generic syscon regmap to work. I can see devices like mediatek,mt8365-syscfg being described by simple binding have a similar nature, they all describe a register bank and with serval sub nodes to describe devices being instanced under that register block. What makes img,boston-platform-regs special here? Thanks - Jiaxun > > Best regards, > Krzysztof -- - Jiaxun
