usb-storage: make use of srb local variable
Commit
8b52291a0743 ("usb-storage: fix deadlock involving host lock
and scsi_done") added a local variable to usb_stor_control_thread() in
the usb-storage driver. This local variable holds the value of
us->srb, for use after the host lock has been released.
But as long as we have the value in a local variable, we may as well
use it instead of dereferencing the us pointer all over the place.
This patch makes no functional change; it just makes the code a little
shorter and a little neater.

1. Split out extcon header file for consumer and provider device
: The extcon has two type of extcon devices as following.
- 'extcon provider deivce' adds new extcon device and detect
the state/properties of external connector. Also, it notifies the
state/properties to the extcon consumer device.
- 'extcon consumer device' gets the change state/properties
from extcon provider device.
Prior to that, include/linux/extcon.h contains all exported API
for both provider and consumer device driver. To clarify the meaning
of header file and to remove the wrong use-case on consumer device.
- include/linux/extcon-provider.h includes API for the provider device driver.
- include/linux/extcon.h includes the API for the consumer device driver.
2. Support the SmartDock accessory on extcon-max77843.c device driver
- Support the SmartDock accessory which detects following connectors
at the same time.
: USB host throught USB hub for mouse, keyboard and so on.
: MHL connector for video output.
: Charger connector for battery charging.
- It tested with Unitek Y-2165 MHL+OTG Hub Smart Phone Dock.
3. Fix the minor issue of extcon driver
- Delete the unneeded initialization in extcon-max14577.
- Make extcon_info static const in order to fix the warning.

The dwc2 driver got a few improvements to how we handle gadget state

setup, the sysfs /sys/class/udc/
f72c0000.usb/state file would
report "configured" no matter the state of the OTG port.
This patch adds a call so that we report to the UDC layer when
the gadget device is disconnected.
This patch does depend on the previous patch ("usb: dwc2:

And the usb devices connected are basically hung at this point.
It seems like if we're in host mode, we probably shouldn't run
the dwc2_hostg_ep_disable logic, so this patch returns an error
in that case.
With this patch (along with the previous patch in this set), we avoid
the mismatched interrupts and connected usb devices continue to function.
I'm not sure if some other solution would be better here, but this seems
to work, so I wanted to send it out for input on what the right approach
should be.

usb: dwc2: Improve gadget state disconnection handling
In the earlier commit
dad3f793f20f ("usb: dwc2: Make sure we
disconnect the gadget state"), I was trying to fix up the
fact that we somehow weren't disconnecting the gadget state,
so that when the OTG port was plugged in the second time we
would get warnings about the state tracking being wrong.
(This seems to be due to a quirk of the HiKey board where
we do not ever get any otg interrupts, particularly the session
end detected signal. Instead we only see status change
interrupt.)
The fix there was somewhat simple, as it just made sure to
call dwc2_hsotg_disconnect() before we connected things up
in OTG mode, ensuring the state handling didn't throw errors.
But in looking at a different issue I was seeing with UDC
state handling, I realized that it would be much better
to call dwc2_hsotg_disconnect when we get the state change
signal moving to host mode.
Thus, this patch removes the earlier disconnect call I added
and moves it (and the needed locking) to the host mode
transition.

USB: Force disconnect Huawei 4G modem during suspend
When going into S3 suspend, the Acer TravelMate P648-M and P648-G3
laptops immediately wake up 3-4 seconds later for no obvious reason.
Unbinding the integrated Huawei 4G LTE modem before suspend avoids
the issue, even though we are not using the modem at all (checked
from rescue.target/runlevel1). The problem also occurs when the option
and cdc-ether modem drivers aren't loaded; it reproduces just with the
base usb driver. Under Windows the system can suspend fine.
Seeking a better fix, we've tried a lot of things, including:
- Check that the device's power/wakeup is disabled
- Check that remote wakeup is off at the USB level
- All the quirks in drivers/usb/core/quirks.c e.g. USB_QUIRK_RESET_RESUME,
USB_QUIRK_RESET, USB_QUIRK_IGNORE_REMOTE_WAKEUP, USB_QUIRK_NO_LPM.
but none of that makes any difference.
There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.
Introduce a quirk to disable the port during suspend when the modem is
detected.
The modem from the P648-G3 model is:

drivers: phy: add calibrate method
Some quirky UDCs (like dwc3 on Exynos) need to have their phys calibrated e.g.
for using super speed. This patch adds a new phy_calibrate() method.
When the calibration should be used is dependent on actual chip.
In case of dwc3 on Exynos the calibration must happen after usb_add_hcd()
(while in host mode), because certain phy parameters like Tx LOS levels
and boost levels need to be calibrated further post initialization of xHCI
controller, to get SuperSpeed operations working. But an hcd must be
prepared first in order to pass it to usb_add_hcd(), so, in particular, dwc3
registers must be available first, and in order for the latter to happen
the phys must be initialized. This poses a chicken and egg problem if
the calibration were to be performed in phy_init(). To break the circular
dependency a separate method is added which can be called at a desired
moment after phy intialization.

PCI: dra7xx: Create functional dependency between PCIe and PHY
PCI core access configuration space registers in resume_noirq callbacks.
In the case of dra7xx, PIPE3 PHY connected to PCIe controller has to be
enabled before accessing configuration space registers. Since
PIPE3 PHY is enabled by only configuring control module registers, no
aborts has been observed so far (though during noirq stage, interface
clock of PIPE3 PHY is not enabled).
With new TRM updates, PIPE3 PHY has to be initialized (PIPE3 PHY
registers has to be accessed) as well which requires the interface
clock of PIPE3 PHY to be enabled. The interface clock of PIPE3 PHY is
derived from OCP2SCP and hence PCIe PHY is modeled as a child of
OCP2SCP. Since pm_runtime is not enabled during noirq stage,
pm_runtime_get_sync done in phy_init doesn't enable
OCP2SCP clocks resulting in abort when PIPE3 PHY registers are
accessed.
Create a function dependency between PCIe and PHY here to make
sure PCIe is suspended before PCIe PHY/OCP2SCP and resumed after
PCIe PHY/OCP2SCP.

phy: rockchip-typec: Avoid magic numbers + add delays in aux calib
NOTE: nothing is known to be fixed by this change, but it does enforce
some delays that are documented to be necessary. Possibly this could
fix some corner cases.
The function tcphy_dp_aux_calibration(), like most of the functions in
the type C PHY, is mostly undocumented and filled with mysterious,
hardcoded numbers.
Let's attempt to try to document some of these numbers and clean the
function up a little bit. Here's the actual cleanup that happened
here:
1. All magic numbers were replaced with bit definitions.
2. For registers that we modify multiple times I now keep track of the
value of the register rather than randomly doing a
read/modify/write or just hardcoding a new number based on knowing
what the old number was.
3. Delay 10 ms (vs 1 ms) after writing the calibration code. No idea
if this is important but it matches the example in the docs.
4. Whenever setting a "delayed" version of a signal always put an
explicit delay in the code. No known problems were seen without
this delay but it seems wise to have it. Whenever a delay of "at
least 100 ns" was specified I used a delay of 1 us.
5. Added comments to some of the bits of code.
6. Removed duplicate setting of TX_ANA_CTRL_REG_5 (to 0)
7. Moved setting of TX_ANA_CTRL_REG_3 to the same place it was in the
sample code. Note that TX_ANA_CTRL_REG_3 ought to be initted to 0
(and elsewhere we assume that we just got a reset), but it seems
fine to be explicit.
8. Treats the calibration code as a 7-bit two's complement number.
This isn't strictly required, but seems slightly cleaner. The docs
say "treat this as a two's complement number, but it should never
be negative". If we ever read the "adjustment" codes as documented
then perhaps the two's complement bit will matter more.
There are still a few weird / mysterious things around aux init and
this doesn't attempt to fix all of them. Mostly it's aimed at doing
changes that should be _very_ safe and add a lot of clarity. Things
specifically not done:
A) Resolve the fact that some registers are read/modify/write and
others are explicitly initted to a value. We always call
tcphy_dp_aux_calibration() right after resetting the PHY so it's
probably not critical, but it's a little weird that the code is
inconsistent.
B) Fully resolve the documented init sequence with the current one.
We still have a few mystery steps and we also leave out turning on
TXDA_DRV_LDO_BG_FB_EN and TXDA_DRV_LDO_BG_REF_EN, which is in the
sample code.
C) Clean things up to read all the bits of the calibration code. This
will hopefully come in a followup change.
This also doesn't attempt to document any of the other parts of the
PHY--just the aux init which is all I got docs for.
