Subject: [PATCH v3 0/3] RK3588 USB3 host controller support
Hi,
This adds RK3588 USB3 host controller support. The same DT binding
will be used for the two dual-role controllers, which are also DWC3
based, but using a different PHY and don't need the extra UTMI/PIPE
clocks.
The series has been tested with Radxa Rock 5B, which uses the controller
for the upper USB3 port. The patch enabling &combphy2_psu and &usbhost3_0
for this board will be send separately once this series has been merged.
Changes since PATCHv2:
* https://lore.kernel.org/all/20230720173643.69553-1-sebastian.reichel@collabora.com/
* update binding, so that "utmi" and "pipe" clocks may only be used on RK3588;
at the same time do not allow "grf_clk" for RK3568, which does not have a GRF
clock for USB3.
Changes since PATCHv1:
* https://lore.kernel.org/all/20230719174015.68153-1-sebastian.reichel@collabora.com/
* use same compatible for USB3 host and drd controllers (Krzysztof Kozlowski)
* do not update reset-names (Krzysztof Kozlowski)
- note: I dropped reset-names property, since there is only one reset line
anyways. Binding could stay the same, since the reset-names property is
optional
* use "ref_clk", "suspend_clk" and "bus_clk" instead of "ref", "suspend" and "bus",
so that they are the same as in RK3568 (Krzysztof Kozlowski)
* rename handle name to "usb_host2_xhci" (Michael Riesch)
* use RK356x style DWC3 binding instead of DWC3399 style
- required adding an extra patch, so that the DWC3 core supports enabling
the UTMI/PIPE clocks
