[PATCH v2 0/2] drm/bridge: lt9211: Add drive-strength-microamp DT property

[Boerge Struempfel]

The LT9211 LVDS TX output driver current is currently hardcoded to
0x8 (~25 uA). Some board layouts require a different drive strength
to meet signal integrity requirements.

This series adds support for the standard 'drive-strength-microamp'
DT property, allowing board DTs to select one of sixteen discrete
current levels between 12 uA and 36 uA. The default preserves the
existing behaviour.

Changes in v2:
- Use u8 instead of u32 for the lookup table array (values fit in u8)
- Warn when drive-strength-microamp exists in DT but is malformed
