… support Enable the Shikra MDSS display subsystem on the Qualcomm Shikra IQS EVK board and add the Lontium LT9611UXD DSI-to-HDMI bridge node. The LT9611UXD is connected via I2C (bus 4, address 0x41), powered by a GPIO-controlled 3.3V regulator (PM8150 GPIO4) and an always-on 1.8V rail. Reset is on GPIO76 and interrupt on GPIO85. The bridge receives DSI output from MDSS and drives an HDMI-A connector, with the link wired as: DPU -> DSI0 -> LT9611UXD -> HDMI.
