Subject: [PATCH v5 0/3] generic-ohci/ehci: add RK3588 support

Hi,

This increases the max. allowed clocks for generic-ohci from 3 to 4.
On RK3588 a total of 4 clocks is required to access the OHCI registers.
EHCI already supports 4 clocks.

Changes since PATCHv4:
 * https://lore.kernel.org/linux-usb/20230413173150.71387-1-sebastian.reichel@collabora.com/
 * Rebase to v6.4-rc1
 * Re-add minItems for rockchip,rk3588-ohci = false

Changes since PATCHv3:
 * https://lore.kernel.org/all/20230406135552.23980-1-sebastian.reichel@collabora.com/
 * Fix the PATCH version in the patchset subjects :)
 * Collect Rob Herrings's Reviewed-by
 * Drop maxItems = 4 from rockchip,rk3588-ohci = true branch (4 is the default value)
 * Drop minItems = 1 from rockchip,rk3588-ohci = false branch (1 is the default value)

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
