| |
Add the microchip,sama7d65-i3c-hci compatible string to the MIPI I3C HCI binding. The Microchip SAMA7D65 I3C controller is based on the MIPI HCI specification but requires two clocks, so add a conditional constraint when this compatible is present.
Signed-off-by: Manikandan Muralidharan <manikandan.m@microchip.com> --- Changes in v5: - drop min/maxItems around clock - use else clause - cosmetic fixes
Changes in v4: - Define and describe the clock in the top-level properties --- .../devicetree/bindings/i3c/mipi-i3c-hci.yaml | 27 ++++++++++++++++--- 1 file changed, 23 insertions(+), 4 deletions(-)
