Workaround introduced for i.MX53 in be9cae2479f48 ("usb: chipidea:
imx: Fix ULPI on imx53") seems to be applicable in case of i.MX51 as
well. Running latest kernel on ZII RDU1 Board (imx51-zii-rdu1.dts)
exhibits a kernel frozen on PORTSC access and applying the workaround
resolves the issue.

The USB Host Controller driver 'ohci-at91.c' reads a Special Function
Register - OHCI Interrupt Configuration Register (AT91_SFR_OHCIICR)
for bits SUSPEND_A/B/C. These bits are defined in sama5d2 alone, so
sfr register mapping is done with compatible string "atmel,sama5d2-sfr".
This gives a kernel warning 'failed to find sfr node' with non sama5d2
cpus which is removed here, thus leaving it up to having a proper DTS.

It's amazing that this driver ever worked, but now that x86 doesn't
allow USB data to be sent off of the stack, it really does not work at
all. Fix this up by properly allocating the data for the small
"commands" that get sent to the device off of the stack.
We do this for one command by having a whole urb just for ack messages,
as they can be submitted in interrupt context, so we can not use
usb_bulk_msg(). But the poweron command can sleep (and does), so use
usb_bulk_msg() for that transfer.

USB-serial updates for v4.18-rc1
Here are the USB-serial updates for 4.18-rc1, including:
- support for hardware-assisted XON/XOFF output flow control for pl2303
- fix for a long-standing IXON/IXOFF mixup in ftdi_sio
- blacklist of two apparently unused dwm-158 modem interfaces that
confused some user space daemon (option)

Included are also various clean ups.

Now we have a proper implementation for the power irq handling and this
quirk is not needed anymore. In fact, it is causing card detection delays
on apq8096 platforms and the following error is displayed:
sdhci_msm 74a4900.sdhci: mmc0: pwr_irq for req: (4) timed out
The quirk is forcing the controller to retain 1.8V signalling on the slot
even when a new card is inserted, which is not correct. The proper behavior
would be to reset the controller in order to start with 3.3V signaling.

SoC have internal I/O buses that can't be proved for devices. The
devices on the buses can be accessed directly without additinal
configuration required. This type of bus is represented as
"simple-bus". In some platforms, we name "soc" with "simple-bus"
attribute and many devices are hooked under it described in DT
(device tree).
In commit bf74ad5bc417 ("Hold the device's parent's lock during
probe and remove") to solve USB subsystem lock sequence since
USB device's characteristic. Thus "soc" needs to be locked
whenever a device and driver's probing happen under "soc" bus.
During this period, an async driver tries to probe a device which
is under the "soc" bus would be blocked until previous driver
finish the probing and release "soc" lock. And the next probing
under the "soc" bus need to wait for async finish. Because of
that, driver's async probe for init time improvement will be
shadowed.
Since many devices don't have USB devices' characteristic, they
actually don't need parent's lock. Thus, we introduce a lock flag
in bus_type struct and driver core would lock the parent lock base
on the flag. For USB, we set this flag in usb_bus_type to keep
original lock behavior in driver core.
Async probe could have more benefit after this patch.

It is seen that just enabling the TSC module triggers a HW_PEN IRQ
without any interaction with touchscreen by user. This results in first
suspend/resume sequence to fail as system immediately wakes up from
suspend as soon as HW_PEN IRQ is enabled in suspend handler due to the
pending IRQ. Therefore clear all IRQs at probe and also in suspend

Nothing prevents I2C clients to access I2C while Tegra's driver is being
suspended, this results in -EBUSY error returned to the clients and that
may have unfortunate consequences. In particular this causes problems
for the TPS6586x MFD driver which emits hundreds of "failed to read
interrupt status" error messages on resume from suspend. This happens if
TPS6586X is used to wake system from suspend by the expired RTC alarm
timer because TPS6586X is an I2C device driver and its IRQ handler reads
the status register while Tegra's I2C driver is suspended, i.e. just after
kernel enabled IRQ's during of resume-from-suspend process.
Note that the removed tegra_i2c_resume() invoked tegra_i2c_init() which
performs HW reset. That seems was also not entirely correct because moving
tegra_i2c_resume to an earlier stage of resume-from-suspend process causes
I2C transfer to fail in the case of TPS6586X. It is fine to remove the
HW-reinitialization for now because it should be only needed in a case of
using lowest power-mode during suspend, which upstream kernel doesn't
support.

PLL0 on davinci/da850-type device needs to be registered early in boot
because it is needed for clocksource/clockevent. Change the driver
to use CLK_OF_DECLARE for this special case.

This modifies the TI Davinci PLL clock driver to allow for the case
when dev == NULL. On some (most) SoCs that use this driver, the PLL
clock needs to be registered during early boot because it is used
for clocksource/clkevent and there will be no platform device available.

Fix parent of EMAC and voice codec PSC clocks. Documentation is clear
on EMAC clock parent, but its not fully clear on parent of voice codec
clock. The implementation chosen is matches arch/arm/mach-davinci/dm365.c.
Add a comment explaining this for posterity.
There is only one power domain on DM365. Fix the power domain of voice
codec and vpss dac modules.
While at it, add a comment explaining how the parent of vpss dac clock was
derived. Note that this patch does not touch the parent of vpss dac clock.

The clkdev lookups for the ASP0/1 devices on TI DM355 were declared, but
not assigned to any LPSC. This assigns the clkdev lookups to the

This fixes the parent clock names of the SYSCLKn clocks for the DM355
SoC in the TI DaVinici PLL clock driver.
It appears that this name just didn't get updated to the correct name
like the other SoCs during the driver's development.

This removes pll2_sysclk2 from the TI DM355 clock driver. This SoC
doesn't have such a clock. Also, SYSCLK_ALWAYS_ENABLED is transferred
to pll2_sysclk1 since it drives the DDR and doesn't have another
mechanism to keep it on.

To enable XIP it is executed both normal and error cases.
This call can be moved after the for loop as same with erase chip.

Currently the functions use to check both chip ready and good.
But the chip ready is not enough to check the operation status.
So change this to check the chip good instead of this.
About the retry functions to make sure the error handling remain it.

For the word write functions it is retried for error.
But it is not implemented to retry for the erase functions.
To make sure for the erase functions change to retry as same.
This is needed to prevent the flash erase error caused only once.
It was caused by the error case of chip_good() in the do_erase_oneblock().
Also it was confirmed on the MACRONIX flash device MX29GL512FHT2I-11G.
But the error issue behavior is not able to reproduce at this moment.
The flash controller is parallel Flash interface integrated on BCM53003.

For the word write it is checked if the chip has the correct value.
But it is not checked for the write buffer as only checked if ready.
To make sure for the write buffer change to check the value.
It is enough as this patch is only checking the last written word.
Since it is described by data sheets to check the operation status.

Driver switches vif sta_state into QTNF_STA_CONNECTING when cfg80211
core initiates connect procedure. Further this state is changed either
to QTNF_STA_CONNECTED or to QTNF_STA_DISCONNECTED by BSS_JOIN and
BSS_LEAVE events from firmware. However it is possible that no such
events will be sent by firmware, e.g. if EAPOL timed out.
In this case vif sta_mode will remain in QTNF_STA_CONNECTING state and
all subsequent connection attempts will fail with -EBUSY error code.
Fix this by perfroming STA state transition from QTNF_STA_CONNECTING
to QTNF_STA_DISCONNECTED in cfg80211 disconnect callback.
No need to rely upon firmware events in this case.
