Changes in v5:
- Adapt clock bit ratio when TMDS is over 340M
- Used sized integers for register read/writes
- Removed useless comments
- Shortened function names
- Link to v4: https://lore.kernel.org/r/20220919-v4-0-bdc21e1307e9@baylibre.com

Changes in v4:
- Dedicated series for HDMI phy support (without the drm/ related
  changes)
- Removed useless variable initializations in phy driver
- Link to v3: https://lore.kernel.org/r/20220919-v3-0-a803f2660127@baylibre.com

Changes in v3:
- phy: Grouped register and bit definition together to add clarity
- dt-bindings: Addressed comments
- Link to v2: https://lore.kernel.org/r/20220919-v2-0-8419dcf4f09d@baylibre.com

Changes in v2:
- Removed syscon requirement from the hdmi node
- Use as much as possible bit FIELD_PREP/FIELD_GET macros across all the
  patches
- Make cec optional dynamically instead of hardcoded with a flag
- Renamed hdmi variants to v1 (legacy) and v2 (mt8195) while waiting for
  a better name
- Rework hdmi v2 code to use a connector (same as v1)
- Remove "magic" 0x43 addr special handling in hdmi ddc code
- Link to v1: https://lore.kernel.org/r/20220919-v1-0-4844816c9808@baylibre.com

Please disregard this, as I meant to send v6 and not a new v5...
link to the actual v6 is here:

Sorry for spamming your inboxes,
