Hi,
Series adds a PCIe driver for the Renesas RZ/G3S SoC.
It is split as follows:
- patches 1-2/6: add PCIe support for the RZ/G3S SoC
- patches 3-6/6: add device tree support and defconfig flag
Please provide your feedback.
Merge strategy, if any:
- patches 1-2/6 can go through the PCI tree
- patches 3-6/6 can go through the Renesas tree
Thank you,
Claudiu Beznea
Changes in v8:
- in patch 2/6 corrected typo, used proper variable for IRQ in
debug message
Changes in v7:
- rebased on top of v6.18-rc1
Changes in v6:
- addressed review comments on DT bindings and driver code
- per-patch changes are described in each individual patch
Changes in v5:
- dropped patch
"arm64: dts: renesas: rzg3s-smarc-som: Update dma-ranges for PCIe"
and introduced patch
"arm64: dts: renesas: rzg3s-smarc-som: Add PCIe reference clock"
- addressed review comments
- per-patch changes are described in each individual patch
Changes in v4:
- dropped v3 patches:
- "clk: renesas: r9a08g045: Add clocks and resets support for PCIe"
- "soc: renesas: rz-sysc: Add syscon/regmap support"
as they are already integrated
- dropped v3 patch "PCI: of_property: Restore the arguments of the
next level parent" as it is not needed anymore in this version due
port being added in device tree
- addressed review comments
- per-patch changes are described in each individual patch
Changes in v3:
- added patch "PCI: of_property: Restore the arguments of the next level parent"
to fix the legacy interrupt request
- addressed review comments
- per-patch changes are described in each individual patch
Changes in v2:
- dropped "of/irq: Export of_irq_count()" as it is not needed anymore
in this version
- added "arm64: dts: renesas: rzg3s-smarc-som: Update dma-ranges for PCIe"
to reflect the board specific memory constraints
- addressed review comments
- updated patch "soc: renesas: rz-sysc: Add syscon/regmap support"
- per-patch changes are described in each individual patch
