Drop the #address/size-cells down to 1 if you're against having 0x0s.

Maybe in other cases, I've never seen it for reg. The dts coding style examples even have 0x0s in them. For other properties, sure this might be the "new" way of doing it but not for reg, probably in part because it makes it difficult to see if the number matches the number of cells in #address/size-cells.

Like the existing AXE-1-16M integration, BXS-4-64 uses the single clock integration in the TI k3-j721s2. Signed-off-by: Matt Coster <matt.coster@imgtec.com> --- .../devicetree/bindings/gpu/img,powervr-rogue.yaml | 45 ++++++++++++++++++++++ 1 file changed, 45 insertions(+)
