R-Car V4H actually has two SCIF_CLK pins. The second pin provides the SCIF_CLK signal for HSCIF2 and SCIF4. Fixes: a4c31c56 ("arm64: dts: renesas: r8a779g0: Add SCIF nodes") Fixes: 39d9dfc6 ("arm64: dts: renesas: r8a779g0: Add remaining HSCIF nodes") Signed-off-by:

The White Hawk Single board is a single-board integration of the Renesas White Hawk CPU and Breakout board stack, based on the R-Car V4H ES2.0 (R8A779G2) SoC. For now, the only visible differences compared to the board stack are: - The SoC is an updated version of R-Car V4H (R8A779G0), - The serial console uses an FT2232H instead of a CP2102 USB-UART bridge, with CTS/RTS wired.

The White Hawk CSI/DSI and RAVB/Ethernet(1000Base-T1) sub boards are not specific to R-Car V4H. Hence rename their DTS file names to drop the "r8a779g0-" prefix, and remove any references to R-Car V4H. Signed-off-by:

According to Table 8.1, "Summary of Module Power, Reset condition and Clock assignment" of the R-Mobile APE6 Hardware Manual Rev. 0.7, the parent clock of the thermal sensor clock is the Common Peripheral (CP) clock, which runs at 13 MHz (main clock / 2). As the R-Car Thermal driver does not use the clock rate, this change has no functional impact. Signed-off-by:

Add the Common Peripheral (CP) clock, which is driven by the main clock / 2 during normal system operation, but may be driven by EXTALR during early system boot, when SYSCLK_EN is still low. As the latter is irrelevant to Linux, just model it as a fixed clock driven from main_div2_clk. Switch all users of main_div2_clk that are documented to be clocked by the CP clock to cp_clk, to better reflect the actual clock topology. Signed-off-by:

External clocks should be defined as zero-Hz clocks in the SoC .dtsi, and overridden in the board .dts when present. Correct the clock rate of extal1 from 25 to 26 MHz, to match the crystal oscillator present on the APE6-EVM board.
