2021-02-09drm/vc4: hdmi: Fix up CEC registersDom Cobley
The commit 311e305fdb4e ("drm/vc4: hdmi: Implement a register layout abstraction") forgot one CEC register, and made a copy and paste mistake for another one. Fix those mistakes.

The alternative is to move them into the source file that uses then, but they are large and intrusive, so that strategy is being avoided.

2020-09-11drm/vc4: Update type of reg parameter in vc4_hdmi_{read,write}Nathan Chancellor
Clang warns 100+ times in the vc4 driver along the lines of: drivers/gpu/drm/vc4/vc4_hdmi_phy.c:518:13: warning: implicit conversion from enumeration type 'enum vc4_hdmi_field' to different enumeration type 'enum vc4_hdmi_regs' [-Wenum-conversion] HDMI_WRITE(HDMI_TX_PHY_POWERDOWN_CTL, ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~ The HDMI_READ and HDMI_WRITE macros pass in enumerators of type vc4_hdmi_field but vc4_hdmi_write and vc4_hdmi_read expect a enumerator of type vc4_hdmi_regs, causing a warning for every instance of this. Update the parameter type so there is no more mismatch.

2020-09-07drm/vc4: hdmi: Implement a register layout abstractionMaxime Ripard
The HDMI controllers found in the BCM2711 have most of the registers reorganized in multiple registers areas and at different offsets than previously found. The logic however remains pretty much the same, so it doesn't really make sense to create a whole new driver and we should share the code as much as possible. Let's implement some indirection to wrap around a register and depending on the variant will lookup the associated register on that particular variant.
