Sun Apr 20 10:36:29 PDT 2025
Add Retronix R-Car V4H Sparrow Hawk board based on Renesas R-Car V4H ES3.0
(R8A779G3) SoC. This is a single-board computer with single gigabit ethernet,
DSI-to-eDP bridge, DSI and two CSI2 interfaces, audio codec, two CANFD ports,
micro SD card slot, USB PD supply, USB 3.0 ports, M.2 Key-M slot for NVMe SSD,
debug UART and JTAG.

V2: - Add TB from Morimoto-san
- Enable pwm-fan and set PWM to full by default, to achieve maximum
cooling effect unless configured otherwise. The blower fan is user
supplied device, hence this default.
- Add arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk-fan-pwm.dtso
to demonstrate user supplied blower fan configuration.
- Add TB from Niklas
- Rename pins{_,-}mdio, pins{_,-}mii, scif{_,-}clk, sd{_,-}uhs
- Add serial1 = &hscif1; and serial2 = &hscif3
- Rename {Renesas,Retronix} R-Car V4H Sparrow Hawk in commit message
and update R-Car V4H ES3.0 to Renesas R-Car V4H ES3.0
V3: - Remove Renesas 9FGV0441 PCIe clock generator node from I2C bus,
remove clk-x8 clock node used by the PCIe clock generator, use
pcie0_clkref and pcie1_clkref to describe 100 MHz clock supplied
to both the PCIe controller and bus for now. The 9FGV0441 can and
does operate autonomously without any configuration. The 9FGV0441
description will be added in a separate follow up patch, once it
is clear how to describe separate controller and bus clock in DT.
