Subject: [PATCH v2 0/3] Add ITE IT61620 MIPI DSI to HDMI bridge driver

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

- 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-v1-0-3761164d0b98@ite.com.tw
