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