This series adds display support for the Qualcomm Shikra platform.
It introduces the Qualcomm Shikra MDSS display subsystem support
at the SoC level, and enables display on the Qualcomm Shikra CQS
EVK and CQM EVK boards with the required DSI panel nodes.

Changes in v3:
- Drop redundant vph_pwr fixed-regulator node (Krzysztof Kozlowski)
- Remove vin-supply = <&vph_pwr> from lcd_bias node (Krzysztof
Kozlowski).
- Add the new line between the last property and the following
subnodes in mdss block(Konrad).
- Link to v2: https://patch.msgid.link/20260706-shikra-dt-changes-v2-0-56fcd1659ea4@oss.qualcomm.com
Changes in v2:
- Replace QCM2290-specific RPM power domain identifiers with generic
RPMPD_VDDCX/VDDMX macros in Shikra display and DSI nodes.
- Add missing blank line before status = "okay" in &mdss_dsi0 node(Dmitry).
- Split avdd-supply and avee-supply into separate regulators vreg_disp_p
and vreg_disp_n instead of sharing the same lcd_bias regulator(Dmitry).
- Sort tlmm pin state entries by pin number: gpio3, gpio86, gpio91,
gpio151 (Dmitry).
- Add vph_pwr as an always-on fixed regulator representing the main
board power supply, used as vin-supply for lcd_bias.
- Droped the 5th patch "Shikra LT9611UXD support". NAK by Dmitry. Once
the hdmi-dsi driver is fixed then we will post DT changes.
