Signed-off-by: Sankeerth Billakanti <quic_sbillaka@quicinc.com>
---

Changes in v5:
- Change the order of patches
- Remove the backlight nodes
- Remove the bias setting
- Fix compilation issue
- Model VREG_EDP_BP for backlight power

Changes in v4:
- Create new patch for name changes
- Remove output-low

Changes in v3:
- Sort the nodes alphabetically
- Use - instead of _ as node names
- Place the backlight and panel nodes under root
- Change the name of edp_out to mdss_edp_out
- Change the names of regulator nodes
- Delete unused properties in the board file


Changes in v2:
- Sort node references alphabetically
- Improve readability
- Move the pwm pinctrl to pwm node
- Move the regulators to root
- Define backlight power
- Remove dummy regulator node
- Cleanup pinctrl definitions
