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.

2.22.0
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.

Although they're equivalent, I would use
ARRAY_SIZE(adv7533_supply_names) instead of adv7511->num_supplies to
make the code easier to read (otherwise one has to check where
num_supplies is set to validate this function call).

You should align "v1p2" left, with adv7533_supply_names.
I wonder if you couldn't simply hardcode the index, with a comment above
the adv7533_supply_names array to mention that the order of the entries
shall not be modified without updating the locations that hardcode
indices.

Shouldn't you explicitly clear bit 7 when reg_v1p2_uV is not 1200000 ?
Or is there a guarantee it gets reset after a reboot ?

As noted by Neil, I think this config option should be renamed (possibly
to CONFIG_DRM_I2C_ADV753X) and its description updated.

I'll rename the config option as Laurent also suggested to
CONFIG_DRM_I2C_ADV753X and update its description.

Ok, my intention was to have robust code but as you said a comment
before the supply names array is enough.

It is guaranteed that it starts cleared to be safe for the chip if the
voltage is 1.8V.

Ack. Will rename to CONFIG_DRM_I2C_ADV753X and update decription.
