Why? Its seems that the switch to regmap APIs is not very necessary, as ioremap/writel/readl are simple enough and easier to use. Isn't that this just introduce an intermediate layer? It's okay for display bridges/panels that behind I2C bus or SPI bus. But then, why drm/msm still haven't be converted to use the regmap APIs ? Just a few questions, has no opinions to your patch. -- Best regards, Sui
