Hi,
Series adds a PCIe driver for the Renesas RZ/G3S SoC.
It is split as follows:
- patch 1/9: updates the max register offset for RZ/G3S SYSC;
this is necessary as the PCIe need to setup the
SYSC for proper functioning
- patch 2/9: adds clocks and resets support for the PCIe IP
- patch 3/9: fix the legacy interrupt request failure
- patches 4-5/9: add PCIe support for the RZ/G3S SoC
- patches 6-9/9: add device tree support and defconfig flag
Please provide your feedback.
Merge strategy, if any:
- patches 1-2,6-9/9 can go through the Renesas tree
- patches 3-5/9 can go through the PCI tree
Thank you,
Claudiu Beznea
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
