This is likely that checking 'phy->hsic_clk' instead of 'phy->clk' is
expected here.

Use the new of_usb_get_dr_mode_by_phy() function to get the dr_mode
from the musb controller node instead of assuming that having an id_det
gpio means otg mode, and not having one means host mode.
Implement peripheral-only mode by adding a sun4i_usb_phy0_get_id_det
helper which looks at the dr_mode, always registering our extcon and
always monitoring vbus.
If dr_mode is not specified in the dts, do not register phy0 as we then
do not know how to treat it. This is actually a good thing as this means
we will not be registering phy0 on devices where the otg controller is
not enabled in the devicetree.

Two times out of 2000 reboots I ran into the error message
"rockchip_emmc_phy_power: dllrdy timeout". Presumably there is some
corner case where the DLL just takes a little longer to timeout. Let's
give it even more time to handle these corner cases.

It's possible that there are some reasons to turn the PHY on while the
clock is 0. In this case we just won't wait for the DLL to lock.
This is a bit of a stopgap until we figure out exactly when we're
supposed to wait for the DLL to lock and when we're supposed to power
cycle the PHY.
Note: this patch should help with suspend/resume where the system will
try to turn the PHY back on when the clock is 0.

The "phyctrl_frqsel" is described in the Arasan datasheet [1] as "the
frequency range of DLL operation". Although the Rockchip variant of
this PHY has different ranges than the reference Arasan PHY it appears
as if the functionality is similar. We should set this phyctrl field
properly.
Note: as per Rockchip engineers, apparently the "phyctrl_frqsel" is
actually only useful in HS200 / HS400 modes even though the DLL itself
it used for some purposes in all modes. See the discussion in the
earlier change in this series: ("mmc: sdhci-of-arasan: Always power the
PHY off/on when clock changes"). In any case, it shouldn't hurt to set
this always.
Note that this change should allow boards to run at HS200 / HS400 speed
modes while running at 100 MHz or 150 MHz. In fact, running HS400 at
150 MHz (giving 300 MB/s) is the main motivation of this series, since
performance is still good but signal integrity problems are less
prevelant at 150 MHz.

Previous PHY code waited a fixed amount of time for the DLL to lock at
power on time. Unfortunately, the time for the DLL to lock is actually
a bit more dynamic and can be longer if the card clock is slower.
Instead of waiting a fixed 30 us, let's now dynamically wait until the
lock bit gets set. We'll wait up to 10 ms which should be OK even if
the card clock is at the super slow 100 kHz.
On its own, this change makes the PHY power on code a little more
robust. Before this change the PHY was relying on the eMMC code to make
sure the PHY was only powered on when the card clock was set to at least
50 MHz before, though this reliance wasn't documented anywhere.
This change will be even more useful in future changes where we actually
need to be able to wait for a DLL lock at slower clock speeds.

The output tap delay controls helps maintain the hold requirements for
eMMC. The exact value is dependent on the SoC and other factors, though
it isn't really an exact science. But the default of 0 is not very good,
as it doesn't give the eMMC much hold time, so let's bump up to 4
(approx 90 degree phase?). If we need to configure this any further
(e.g., based on board or speed factors), we may need to consider a
device tree representation.

According to the databook, 10.2us is the max time for dll to be ready to
work. However in testing, some chips need 20us for dll to be ready. This
patch adds some extra margin for dllrdy to be ready, fixing our
-ETIMEDOUT issues.

This patch fixes an issue that the extcon_set_cable_state_() is possible
to cause "BUG: scheduling while atomic" because this driver calls
extcon_set_cable_state_() in the interrupt handler and mutex_lock()
is possible to be called by like the following call trace.

If devm_add_action() fails we are explicitly calling the cleanup to free
the resources allocated. Lets use the helper devm_add_action_or_reset()
and return directly in case of error, as we know that the cleanup function
has been already called by the helper if there was any error.

The usb-phy is fully enclosed in the general register files (GRF).
Therefore as seen from the device-tree it shouldn't be a separate
platform-device but instead a sub-device of the GRF - using the
simply-mfd mechanism.
As the usb-phy is part of the kernel for some releases now, we keep
the old (and now deprecated) binding for compatibility purposes.

The initial use for this is for PHYs that have a mode related to USB OTG.
There are several SoCs (e.g. TI OMAP and DA8xx) that have a mode setting
in the USB PHY to override OTG VBUS and ID signals.
Of course, the enum can be expaned in the future to include modes for
other types of PHYs as well.

The interrupt 0 is not a valid interrupt number. In the event where the
retrieval of the vbus-det gpio would return null, the gpiod_to_irq
callback would return 0, while the current code makes the assumption
that it is a valid interrupt, and would go on calling request_irq.
Obviously, this would fail, preventing the driver from probing properly,
while the vbus and id gpios are optional.

This patch fixes an issue that the driver is possible to cause
unexpected repeat interrupts if a board condition is wrong
(e.g. even if the ID pin is as function, a board supplies the VBUS.)
The reason why unexpected repeat interrupts happen is:
1) The driver changed the mode to function if it detected the ID pin
is high and the VBUS is high.
2) After the driver changed function mode, it disabled the "VBUS control"
feature. Then, the VBUS signal will be low.
3) Since the VBUS change interruption happened, the driver checked
the ID pin and VBUS.
4) Since VBUS was low, the driver changed the mode to host and enabled
the "VBUS control" feature. Then the VBUS signal will be high.
5) Since the VBUS change interruption happened, the driver did 1) above.
So, this patch modified the condition in rcar_gen3_device_recognition()
to check the ID pin only.
Fixes: 1114e2d (phy: rcar-gen3-usb2: change the mode to OTG on the combined channel)

instead of defining all functions as static inlines,
let's move them to udc-core and export them with
EXPORT_SYMBOL_GPL, that way we can make sure that
only GPL drivers will use them.
As a side effect, it'll be nicer to add tracepoints
to the gadget API.
While at that, also fix Kconfig dependencies to
avoid randconfig build failures.

If bootloader has set a wrong DPLL then we must trash those values
and re-program it anyways. This fixes USB3 devices not being enumerated
on beagle-x15 if usb was started in u-boot.
We don't re-program SATA DPLL if it is locked as it was causing
SATA failures if device was hotpluged after boot.

A rework of the exynos-mipi-video driver caused a warning
about the new __set_phy_state function potentially accessing
a variable before its initialization:
drivers/phy/phy-exynos-mipi-video.c: In function '__set_phy_state':
drivers/phy/phy-exynos-mipi-video.c:238:13: error: 'val' may be used uninitialized in this function [-Werror=maybe-uninitialized]
return val & data->resetn_val;
~~~~^~~~~~~~~~~~~~~~~~
drivers/phy/phy-exynos-mipi-video.c:235:6: note: 'val' was declared here
u32 val;
The failure scenario here is the offset passed into a the
stub regmap_read() function that does not modify its output,
however regmap_read() can also fail for other reasons, so
adding error handling (in this case, returning zero from
is_running) seems the best solution.
Note that this warning showed up with the ARM s5pv210_defconfig,
indicating that we most likely want to either enable CONFIG_REGMAP
in that defconfig as well, or disable the phy-exynos-mipi-video
driver.

At least on n900 we have phy-twl4030-usb only generating cable
interrupts, and then have a separate USB PHY.
In order for musb to know the real cable status, we need to
clear any cached state until musb is ready. Otherwise the cable
status interrupts will get just ignored if the status does
not change from the initial state.
To do this, let's add a return value to musb_mailbox(), and
reset cached linkstat to MUSB_UNKNOWN on error. Sorry to cause
a bit of churn here, I should have added that already last time
patching musb_mailbox().
