63bd0f1922 phy: rockchip-usb: add usb-uart setup for rk3188
The rk3188 also supports bringing the uart2 out through
the usb dm+dp pins, so add the necessary setup for it.

rk3066 does not seem to support usb-uart functionality and this
particular phy was only used on older Rockchip socs, so this leaves
room for a bit of cleanup as well, as there most likely won't be new
additions in the driver.

6c7103aa02 phy: phy-twl4030-usb: fix denied runtime access
When runtime is not enabled, pm_runtime_get_sync() returns -EACCESS,
the counter will be incremented but the resume callback not called,
so enumeration and charging will not start properly.
To avoid that happen, disable irq on suspend and recheck on resume.

Practically this happens when the device is woken up from suspend by
plugging in usb.

8dde0008ff phy: renesas: rcar-gen3-usb2: Check a property to use otg pins
Since All R-Car Gen3 SoCs have dedicated otg pins actually but
some boards don't use the otg pins (e.g. R-Car D3 Draak and R-Car E3
Ebisu), the driver should not choose SoC model base by using
rcar_gen3_phy_usb2_match_table's data. So, this patch checks a
"renesas,no-otg-pins" property to set the "uses_otg_pins".

Note that since r8a77995-draak.dts and r8a77990-ebisu.dts don't have
'dr_mode = "otg";' for now, if we apply this patch, no behavior
changes (the value of "uses_otg_pins" is false).

fdf37e1a1f phy: qcom-qmp: Enable pipe_clk before PHY initialization
QMP PHY for USB/PCIE requires pipe_clk for locking of
retime buffers at the pipe interface. Driver checks for
PHY_STATUS without enabling pipe_clk due to which
phy_init() fails with initialization timeout.
Though pipe_clk is output from PHY (after PLL is programmed
during initialization sequence) to GCC clock_ctl and then fed
back to PHY but for PHY_STATUS register to reflect successful
initialization pipe_clk from GCC must be present.
Since, clock driver now ignores status_check for pipe_clk on
clk_enable/disable, driver can safely enable/disable pipe_clk
from phy_init/exit.

f7f50b2a7b phy: mapphone-mdm6600: Add runtime PM support for n_gsm on USB suspend
We can suspend the mdm6600 over USB via sysfs and then mdm6600 enters
a low-power idle mode. In the low-power mode, mdm6600 radio and n_gsm
uart are functional but we need to use USB mode0 GPIO pin to send a
wake-up pulse to the modem to talk with it over n_gsm.

As the GPIO mode0 line is dual purposed and and also needed by the
USB PHY driver to boot mdm6600 into the correct USB mode, let's also
manage the wake-up GPIO in the USB PHY driver. For the USB PHY idle,
there does not anything specific we need to do for runtime PM after
getting the PHY configured. The PHY framework already idles the USB
PHY when not in use separately from the mdm6600 state.

It seems that it takes about 100 - 200ms for mdm6600 to wake up from
the low-power idle mode. And then mdm6600 stays awake about 1.2s until
it needs to be kicked again. The mdm6600 status GPIO pins don't seem
to change state when mdm6600 changes between normal and idle mode.

Let's manage the mdm6600 mode with runtime PM. If phy-mapphone-mdm6600
sysfs entry for power/control is set to "on", we keep mdm6600 out of
idle by kicking the GPIO line. If the entry is set to "auto" we let
mdm6600 enter low-power state.

The ATH79 USB phy is very simple, it only have a reset. On some SoC a
second reset is used to force the phy in suspend mode regardless of the
USB controller status.

This driver is added to the qualcom directory as atheros is now part
of qualcom and newer SoC of this familly are marketed under the
qualcom name.

167569343f ARM: SoC platform updates for 4.17
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.
