The mvneta hardware appears to lock up in various random ways when
repeatedly switching speeds between 1G and 2.5G, which involves
reprogramming the COMPHY. It is not entirely clear why this happens,
but best guess is that reprogramming the COMPHY glitches mvneta clocks
causing the hardware to fail. It seems that rebooting resolves the
failure, but not down/up cycling the interface alone.
Various other approaches have been tried, such as trying to cleanly
power down the COMPHY and then take it back through the power up
initialisation, but this does not seem to help.
It was finally noticed that u-boot's last step when configuring a
COMPHY for "SGMII" mode was to poke at a register described as
"GBE_CONFIGURATION_REG", which is undocumented in any external
documentation. All that we have is the fact that u-boot sets a bit
corresponding to the "SGMII" lane at the end of COMPHY initialisation.
Experimentation shows that if we clear this bit prior to changing the
speed, and then set it afterwards, mvneta does not suffer this problem
on the SolidRun Clearfog when switching speeds between 1G and 2.5G.
This problem was found while script-testing phylink.
This fix also requires the corresponding change to DT to be effective.

speeds".

If CONFIG_DEBUG_SHIRQ was enabled, r8a77951-salvator-xs could boot
correctly. If we appended "earlycon keep_bootcon" to the kernel
command like, we could get kernel log like below.

This means free_irq() calls the interrupt handler while PM runtime
is not getting if DEBUG_SHIRQ is enabled and rcar_gen3_phy_usb2_probe()
failed. To fix the issue, move the irq registration place to
rcar_gen3_phy_usb2_init() which is ready to handle the interrupts.
Note that after the commit 549b6b55b0 ("phy: renesas: rcar-gen3-usb2:
enable/disable independent irqs") which is merged into v5.2, since this
driver creates multiple phy instances, needs to check whether one of
phy instances is initialized. However, if we backport this patch to v5.1
or less, we don't need to check it because such kernel have single

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

Rather busy cycle. We have a total 99 non-merge commits going into v5.8
merge window. The majority of the changes are in dwc3 this around (31.7%
of all changes). It's composed mostly Thinh's recent updates to get dwc3
to behave correctly with stream transfers. We have also have Roger's for
Keystone platforms and Neil's updates for the meson glue layer.
Apart from those, we have the usual set of non-critical fixes, new
device IDs, spelling fixes all over the place.

The registers which are managed by the meson-gxl-usb3 PHY driver are
actually "USB control" registers (which are "glue" registers which
manage OTG detection and routing of the OTG capable port between the
DWC2 peripheral-only controller and the DWC3 host-only controller).
Drop the meson-gxl-usb3 PHY driver now that the dwc3-meson-g12a-usb
driver supports the USB control registers on GXL and GXM SoCs (these
were previously managed by the meson-gxl-usb3 PHY driver).
