Add the i3c controller devices to the ast2600 g6 common dts. We add all 6 busses to the common g6 definition, but leave disabled through the status property, to be enabled per-platform. Suggested-by: Jeremy Kerr <jk@codeconstruct.com.au> Signed-off-by: Dawid Glazik <dawid.glazik@linux.intel.com> --- v4: - removed i3c aliases - renamed i3c-global node name to generic: syscon v3: - add i3c aliases - rebase on top of latest tree and solve conflicts - as agreed with Jeremy off-list, he said I can take authorship of this going forward v2: - use inline bus representation, without the i3c: label --- arch/arm/boot/dts/aspeed/aspeed-g6.dtsi | 91 +++++++++++++++++++++++++ 1 file changed, 91 insertions(+)
