arm64: dts: renesas: rcar: Add boot phase tags

2025-02-21T15:23:01+00:00

bootph-all as phase tag was added to dt-schema (dtschema/schemas/bootph.yaml) to describe various node usage during boot phases with DT. Add bootph-all for all nodes that are used in the bootloader on Renesas R-Car SoCs. All SoC require CPG clock and its input clock, RST Reset, PFC pin control and PRR ID register access during all stages of the boot process, those are marked using bootph-all property, and so is the SoC bus node which contains these IP. Each board console UART is also marked as bootph-all to make it available in all stages of the boot process.

arm64: dts: renesas: white-hawk-cpu-common: Add pin control for DSI-eDP IRQ

2024-11-03T11:27:45+00:00

When the DSI to eDP bridge was added, pin control for the IRQ pin was left out, because the pin controller did not support INTC-EX pins yet. Commit 10544ec1b3436037 ("pinctrl: renesas: r8a779g0: Add INTC-EX pins, groups, and function") added support for these pins, so add the missing pin control description.

arm64: dts: renesas: rcar-gen4: Switch PCIe to reset-gpios

Commit 42694f9f6407a933 ("dt-bindings: PCI: add snps,dw-pcie.yaml") deprecated the "reset-gpio" property in favor of "reset-gpios". Hence replace the "reset-gpio" property by "reset-gpios" in PCIe device nodes.

arm64: dts: renesas: r8a779g0: Use MDIO node for all AVB devices

2024-05-28T07:32:21+00:00

Switch from defining the PHY inside the AVB node itself and create a dedicated MDIO node for AVB0, the only AVB describing a PHY. This is needed as adding PHYs to AVB1 and AVB2 will require setting MDIO bus parameters and thus requires a dedicated node.
