This patch-set add support for ADV7535 part in ADV7511 driver.
ADV7535 and ADV7533 are pin to pin compatible parts but ADV7535
support TMDS clock upto 148.5Mhz and resolutions up to 1080p@60Hz.
---
Changes in v3:
- remove CONFIG_DRM_I2C_ADV7533 from Kconfig. Now driver support
all chip versions
- create macros for v1p2 config registers
- remove dummy functions from header

ADV7535 is a part compatible with ADV7533 but it supports 1080p@60hz and
v1p2 supply is fixed to 1.8V

ADV7535 is a DSI to HDMI bridge chip like ADV7533 but it allows
1080p@60Hz. v1p2 is fixed to 1.8V on ADV7535 but on ADV7533 can be 1.2V
or 1.8V and is configurable in a register.

In patch adding support for adv7535 you modifies adv7533 path. It looks
suspicious, maybe it would be better to extract it to separate patch.
Anyway this change requires tests from adv7533 users.
Beside this the patch looks OK.
