The dwc2 interrupt handler is quite slow. On rk3288 with a few things

In commit 94dfd7edfd5c ("USB: HCD: support giveback of URB in tasklet

Let's take advantage of this in dwc2.
This speeds up the dwc2 interrupt handler considerably.

So I told the ppc people this many years ago, and I guess I'll tell
you guys too: 16kB pages are not actually
All other host controllers who want aligned buffers for DMA do it a
certain way. Let's do that too instead of working behind the USB core's
back. This makes our interrupt handler not take forever and also rips
out a lot of code, simplifying things a bunch.
This also has the side effect of
Previously we needed to set the max_transfer_size to explicitly be 65535
because the old driver would detect that our hardware could support much
bigger transfers and then would try to do them. This wouldn't work
since the DMA alignment code couldn't support it.

Add the #clock-cells properties for the usbphy nodes as they
provide the pll-clocks now.

Veyron devices try to always set the source for usbphy480m to the usbphy0
that is the phy connected to the otg controller, because the firmware-
default is usbphy1, the ehci-controller connected to the internal camera
that might get turned off way easier to save power.
In the mainline kernel we
The USB phys on Rockchip SoCs contain their own internal PLLs to create
the 480MHz needed. Additionally this PLL output is also fed back into the
core clock-controller as possible source for clocks like the GPU or others.
Until now this was modelled incorrectly with a "virtual" factor clock in
This introduces a common struct that holds data belonging to
the umbrella device that contains all the phys and that we
want to use later.

The otgphy clocks really only drive the phy blocks. These in turn
contain plls that then generate the 480m clocks the clock controller
uses to supply some other clocks like uart0, gpu or the video-codec.
So fix this structure to actually respect that hirarchy and removed
that usb480m fixed-rate
Patches 1-7 fix a long-standing issue with the clock-tree of Rockchip SoCs
namely our ignorance of the usbphy-internal pll that creates the needed
480MHz but is also a supply-clock back to the core clock-controller in
Rockchip SoCs.
Till now that was worked around using a virtual clock in the cru
Most newer Rockchip SoCs provide the possibility to use a usb-phy
as passthrough for the debug uart (uart2), making it possible to
for example get console output without needing to open the device.
This patch adds an early_initcall to enable this functionality
conditionally via the commandline
Currently the phy driver only gets the optional clock reference but
never puts it again, neither during error handling nor on remove.
Fix that by moving the clk_put to a devm-action that gets called at
the right time when all other devm actions are done.

This unclutters the loop in probe a lot and makes current (and future)
error handling easier to read.

So, if maintainer is okay I'm also okay with those and you may take my tag.
