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 and also disables the corresponding
usb controller in the devicetree.Currently only data for the rk3288 is provided, but at least the
rk3188 and arm64 rk3368 also provide this functionality and will be
enabled later.On a spliced usb cable the signals are tx on white wire(D+) and
rx on green wire(D-).The one caveat is that currently the reconfiguration of the phy
happens as early_initcall, as the code depends on the unflattened
devicetree being available. Everything is fine if only a regular
console is active as the console-replay will happen after the
reconfiguation. But with earlycon active output up to smp-init
currently will get lost.The phy is an optional property for the connected dwc2 controller,
so we still provide the phy device but fail all phy-ops with -EBUSY
to make sure the dwc2 does not try to transmit anything on the
repurposed phy.Signed-off-by: Heiko Stuebner

If we reload phy-twl4030-usb, we get a warning about unbalanced
pm_runtime_enable. Let's fix the issue and also fix idling of the
device on unload before we attempt to shut it down.If we don't properly idle the PHY before shutting it down on removal,
the twl4030 ends up consuming about 62mW of extra power compared to
running idle with the module loaded.Cc: stable@vger.kernel.org

…linux-phy into usb-next
Kishon writes:
phy: for 4.5
*) new PHY driver for hi6220 usb and rcar gen3 usb2
*) deprecate phy-omap-control driver. phy-omap-control driver was added
when there was no proper infrastructure for doing control module
initialization. The phy-omap-control driver is not an 'actual' PHY
driver and it was just a hack to do PHY related control module
initialization. Now with SYSCON framework in the kernel, control
module setttings can be done using APIs provided by syscon.
*) usbphy-internal pll creates the needed 480MHz and is also a
supply-clock back to the core clock-controller in Rockchip SoCs.
This is now modeled as a real clock.
*) calibrate mt65xx usb3 PHY for better eye diagram and receiver
sensitivity.
*) Miscellaneous cleanups.Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

usb: patches for v4.5
A ton of improvements to dwc2 have been made. The
driver should be a lot more stable on v4.5 then ever
before.Our good old dwc3 got a few cleanups and misc fixes
and also added support to Xilinx's integration of
this IP.Yoshihiro Shimoda gives us support for a new USB3
peripheral controller from Renesas.Other than these, the usual misc fixes all over the

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
the clock controller. The one big caveat is that if we turn off the usb phy
via the siddq signal, all analog components get turned off, including the
PLLs. It is therefore possible that a source clock gets disabled without
the clock driver ever knowing, possibly making the system hang.Therefore register the phy-plls as real clocks that the clock driver can
then reference again normally, making the clock hirarchy finally reflect
the actual hardware.The phy-ops get converted to simply turning that new clock on and off
which in turn controls the siddq signal of the phy.Through this the driver gains handling for platform-specific data, to
handle the phy->clock name association.Signed-off-by: Heiko Stuebner

To use the channel 0 of R-Car gen3 as periperal mode, This patch changes
