[PATCH v4 0/5] RK3588 PCIe2 support

[Sebastian Reichel]

Hi,

This adds PCIe v2 support for RK3588. The series has been tested with
the onboard RTL8125 network card on Rockchip RK3588 EVB1 (&pcie2x1l1)
and Radxa Rock 5B (&pcie2x1l2).

Changes since v3:
 * https://lore.kernel.org/all/20230717172651.64324-1-sebastian.reichel@xxxxxxxxxxxxx/
 * Remove unneeded quotes in patch 1 (msi handling)
 * Update patch description of patch 2 (interrupt names) adding information
   about Rockchip specific parts

Changes since v2:
 * https://lore.kernel.org/all/20230713171851.73052-1-sebastian.reichel@xxxxxxxxxxxxx/
 * Removed num-ib-windows/num-ob-windows/num-viewport from DT
 * Added patch making 'msi' irq optional, if 'msi-map' property is available
 * Updated binding according two discussion with Serge Semin, I provided two
   options by adding one extra patch that should be squashed into the main
   one or dropped depending on preferences from DT binding  maintainers.
 * Collected Reviewed-by/Tested-by from Jagan Teki

Changes since v1:
 * https://lore.kernel.org/all/20230616170022.76107-1-sebastian.reichel@xxxxxxxxxxxxx/
 * Dropped patch adding 'RK3588' (queued by Rob)
 * Updated patch adding legacy-interrupt-controller according to comments
   from Rob and Serge
    - added missing additionalProperties: false
    - added all properties to new required property
    - removed useless quotes around interrupt-controller
    - added Rob's Reviewed-by
 * Updated patch adding the missing RK356x/RK3588 interrupt names, so that it
   provides more details about the interrupts
 * Updated the DT patch according to the comment from Jonas Karlman, so that
   the addresses are in 32 bit address space starting at 0x40000000
