[PATCH 0/8] PCI: rzg3s-host: Add PCIe driver for Renesas RZ/G3S SoC

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj at bp.renesas.com>

Hi,

Series adds a PCIe driver for the Renesas RZ/G3S SoC.
It is split as follows:
- patch 1/8:		updates the max register offset for RZ/G3S SYSC;
			this is necessary as the PCIe need to setup the
			SYSC for proper functioning
- patch 2/8:		adds clock, reset and power domain support for
			the PCIe IP
- patch 3/8:		exports of_irq_count() symbol; this is used by the
			proposed driver to get the number of INTx interrupts
- patches 4-5/8:	add PCIe support for the RZ/G3S SoC
- patches 6-8/8:	add device tree support

Please provide your feedback.

Merge strategy, if any:
- patches 1-2,6-8/8 can go through the Renesas tree
- patches 4-5/8 can go through the PCI tree; these depends on patch 3/8,
  proper sync will be needed b/w PCI tree and Rob's tree

Thank you,
Claudiu Beznea
