The icicle kit reference design's v2022.09 release,made some changes to the memory map - including adding the ability to read the fabric clock controllers via the system controller bus & making the PCI controller work with upstream Linux. While the PCI was not working in the v2022.03 design, so nothing is broken there in terms of backwards compatibility, the fabric clocks used in the v2022.03 design were chosen by the individual run of the synthesis tool. In the v2022.09 reference design, the clocks are fixed to use the "north west" fabric Clock Conditioning Circuitry. Make use of a new compatible to denote that this is not backwards compatible. Signed-off-by: Conor Dooley <conor.dooley@microchip.com> --- Krzysztof: you acked this patch in another series, but I moved it here and reworked the patch contents to make the relationship between the compatibles clearer. Since it is basically a new patch just with the same intent, I dropped your ack. --- .../devicetree/bindings/riscv/microchip.yaml | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-)
