[PATCH v4 0/3] drm: bridge: adv7511: Add support for ADV7535

[Bogdan Togorean]

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 v4:
 - get out ADV7533 v1p2 voltage selection of this patch set
 - removal CONFIG_DRM_I2C_ADV7533 from Kconfig moved to new commit

[PATCH v4 2/3] drm: bridge: adv7511: Add support for ADV7535

[Bogdan Togorean]

ADV7535 is a DSI to HDMI bridge chip like ADV7533 but it allows
1080p@60Hz. v1p2 is fixed to 1.8V on ADV7535.
