…ors and pinctrl Rename lt9611-specific regulator and pinctrl labels to more generic names to decouple them from the bridge chip: - vreg_lt9611_vcc -> vreg_disp_3p3 - vreg_lt9611_vdd removed (vdd now sourced from pm8150_s4) - hdmi_reg_en -> lcd_bias_en - lt9611_irq_pin -> bridge_irq_pin - lt9611_rst_pin -> bridge_rst_pin - Add hdmi_connector label to hdmi-connector node Signed-off-by: Mohit Dsor <mohit.dsor@oss.qualcomm.com>
Added DSI-HDMI overlays: - shikra-cqm-evk-hdmi: CQM EVK with LT9611UXD HDMI bridge overlay - shikra-cqs-evk-hdmi: CQS EVK with LT9611UXD HDMI bridge overlay Signed-off-by: Mohit Dsor <mohit.dsor@oss.qualcomm.com>
Added DSI DLC panel support: - shikra-iqs-evk-dlc-panel: IQS EVK with DLC panel overlay Signed-off-by: Mohit Dsor <mohit.dsor@oss.qualcomm.com>
Shikra IQS EVKs can optionally be fitted with an AUO G133HAN01 LVDS panel driven through a TI SN65DSI84 DSI-to-LVDS bridge on i2c3. Add a devicetree overlay that describes the SN65DSI84 bridge and the AUO G133HAN01 panel, and disable HDMI.

Add LT9611UXD DSI-to-HDMI bridge support for the Shikra IQS EVK board
and introduce DT overlay infrastructure for HDMI and panel configurations.
The LT9611UXD bridge 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 DSI0 and drives an HDMI-A connector.
Changes:
Add LT9611UXD HDMI bridge node, MDSS display enable, regulators and
pinctrl for Shikra IQS EVK
Rename HDMI bridge regulators and pinctrl to generic names
(vreg_disp_3p3, bridge_irq_pin, bridge_rst_pin)
Add DT overlay files and Makefile entries for shikra-cqm-evk-hdmi,
shikra-cqs-evk-hdmi and shikra-iqs-evk-dlc-panel
Tested-on: Shikra IQS EVK with LT9611UXD HDMI bridge
