On RK3588 a total of 4 clocks is required to access the OHCI registers. EHCI already supports 4 clocks. Changes since PATCHv2: * https://lore.kernel.org/all/20230404145350.45388-1-sebastian.reichel@collabora.com/ * Added Krzysztof's Ack to the EHCI binding update * Changed OHCI binding update according to Krzysztof's feedback Changes since PATCHv1: * https://lore.kernel.org/all/20230331163148.5863-1-sebastian.reichel@collabora.com/ * changed cover-letter subject * Add Alan's Acked-by to the driver patch increasing the clock count * Update bindings, adding rockchip,rk3588-ohci and rockchip,rk3588-ehci compatibles -- Sebastian Sebastian Reichel (3): dt-bindings: usb: Add RK3588 OHCI dt-bindings: usb: Add RK3588 EHCI usb: host: ohci-platform: increase max clock number to 4 .../devicetree/bindings/usb/generic-ehci.yaml | 1 + .../devicetree/bindings/usb/generic-ohci.yaml | 18 +++++++++++++++++- drivers/usb/host/ohci-platform.c | 2 +- 3 files changed, 19 insertions(+), 2 deletions(-) Reviewed-by: Rob Herring
