The HDMI driver is written with readl/writel I/O to the registers. However, to support the A31 variant, which has a different layout for the DDC registers, it was recommended to use regfields to have a cleaner implementation. To use regfields, we need to create an underlying regmap. This patch only adds the regmap. It does not convert the existing driver accesses to use regmap. Signed-off-by: Chen-Yu Tsai <redacted>
