Subject: [PATCH v4 0/2] Add Rockchip RK3588 GIC ITS support

Hi,

This adds GIC ITS support to Rockchip RK3588, which is affected
by an integration issue effectively breaking shareability support.
PCIe2 support will follow in its own series.

Changelog:
 * Changes since PATCHv3
  - https://lore.kernel.org/lkml/20230417214035.101190-1-sebastian.reichel@collabora.com/
  - Add RB from AngeloGioacchino Del Regno
  - Update patch description
  - Update Kconfig description
  - rename flags from BROKEN_SHAREABILITY to FORCE_NON_SHAREABLE
 * Changes since PATCHv2
  - https://lore.kernel.org/lkml/20230417150038.51698-1-sebastian.reichel@collabora.com/
  - apply changes requested by Marc Zyngier
 * PATCHv1
  - https://lore.kernel.org/lkml/20230227151847.207922-1-lucas.tanure@collabora.com/
  - uses of_dma_is_coherent() instead of providing errata info from kernel
 * RFCv1
  - https://lore.kernel.org/lkml/20230310080518.78054-1-lucas.tanure@collabora.com/
  - uses 0x0201743b IIDR for quirk detection and misses errata #

Greetings,

-- Sebastian
