This patch series adds support for the ITE IT61620 MIPI DSI to HDMI
bridge chip.
The IT61620 is an I2C-controlled bridge that receives MIPI DSI input
and outputs HDMI signals. A single-port MIPI DSI input is converted to
an HDMI 1.4 output. This series introduces:
- A device tree binding YAML file describing the hardware
- A new DRM bridge driver implementing the basic functionality
- A MAINTAINERS entry for the driver

Changes in v2:
- Call the sha1() library function instead of using the crypto_shash
"sha1" in patch 2.
- Rewrite it61620_hdmi_ddc_wait() with readx_poll_timeout() in patch 2. [Pin-yen]
- Rewrite it61620_hdmi_hdcp_wait_ksv_list() with readx_poll_timeout() in
patch 2.
- Replace interrupts-extended with interrupts in patch 1. [Rob]
- Replace dsi-lanes with the standard property data-lanes from the graph
binding. [Rob]
- Replace "#/$defs/port-base" with "#/properties/port" in patch 1. [Rob]
- Drop unused labels and "hdmi" for the node name. [Rob]
- Drop status in patch 1. [Rob]
- Link to v1: https://lore.kernel.org/r/20250714-it61620-0714-v1-0-3761...
