Subject: [PATCH 01/10] clk: rockchip: rk3588: make gate linked clocks ignore
 unused

RK3588 has a couple of hardware blocks called Native Interface Unit
(NIU) that gate the clocks to devices behind them. Effectively this
means that some clocks require two parent clocks being enabled.
Downstream implemented this by using a separate clock driver
("clk-link") for them, which enables the second clock using PM
framework.

In the upstream kernel we are currently missing support for the second
parent. The information about it is in the GATE_LINK() macro as
linkname, but that is not used. Thus the second parent clock is not
properly enabled. So far this did not really matter, since these clocks
are mostly required for the more advanced IP blocks, that are not yet
supported upstream. As this is about to change we need a fix. There
are three options available:

1. Properly implement support for having two parent clocks in the
   clock framework.
2. Mark the affected clocks CLK_IGNORE_UNUSED, so that they are not
   disabled. This wastes some power, but keeps the hack contained
   within the clock driver. Going from this to the first solution
   is easy once that has been implemented.
3. Enabling the extra clock in the consumer driver. This leaks some
   implementation details into DT.

This patch implements the second option as an intermediate solution
until the first one is available. I used an alias for CLK_IS_CRITICAL,
so that it's easy to see which clocks are not really critical once
the clock framework supports a better way to implement this.

Subject: [PATCH 02/10] soc: rockchip: power-domain: add rk3588 mem module
 support

On RK3588 it's also possible to power down the memory used by the
particular power domains via PMU_MEM_PWR_GATE_SFTCON. This adds
support for this feature.

Subject: [PATCH 10/10] arm64: dts: rockchip: rk3588-rock5b: add USB2

Enable USB2 (EHCI and OCHI mode) support for the Radxa ROCK 5 Model B.
This adds USB support on the M.2 Key E, both USB2 ports and USB2 mode
for the upper USB3 port (the one further away from the PCB).

The lower USB3 (closer to the PCB) and the USB-C ports use the RK3588
USB TypeC host controller, which is not yet supported upstream.
