spi: qcom: geni: handle timeout for gpi mode
We missed adding handle_err for gpi mode, so add a new function
spi_geni_handle_err() which would call handle_fifo_timeout() or newly
added handle_gpi_timeout() based on mode

7560ee032b ALSA: seq: virmidi: Add a drain operation
If a driver does not supply a drain operation for outputs, a default code
path will execute msleep(50). Especially for a virtual midi device
this severely limmits the throughput.

This implementation for the virtual midi driver simply flushes the output
workqueue.

93a770b7e1 serial: core: Keep mctrl register state and cached copy in sync
struct uart_port contains a cached copy of the Modem Control signals.
It is used to skip register writes in uart_update_mctrl() if the new
signal state equals the old signal state.  It also avoids a register
read to obtain the current state of output signals.

When a uart_port is registered, uart_configure_port() changes signal
state but neglects to keep the cached copy in sync.  That may cause
a subsequent register write to be incorrectly skipped.  Fix it before
it trips somebody up.

This behavior has been present ever since the serial core was introduced
in 2002:
https://git.kernel.org/history/history/c/33c0d1b0c3eb

So far it was never an issue because the cached copy is initialized to 0
by kzalloc() and when uart_configure_port() is executed, at most DTR has
been set by uart_set_options() or sunsu_console_setup().  Therefore,
a stable designation seems unnecessary.

9a135f16d2 serial: stm32: rework TX DMA state condition
TX DMA state condition is handled by tx_dma_busy boolean.
This boolean is set when dma descriptor is requested and reset when dma
channel is stopped (dma_terminate).

In stm32_usart_serial_remove(), stm32_usart_stop_tx() and
stm32_usart_transmit_chars_dma() fallback error case, DMA channel is
stopped but tx_dma_busy is not handled.

Rework the driver by using two new functions to solve this issue:
- stm32_usart_tx_dma_started return true if DMA TX have a descriptor.
- stm32_usart_tx_dma_enabled return true if DMAT bit is set.

stm32_usart_tx_dma_started uses tx_dma_busy flag to prevent dual DMA
transaction at the same time. This flag is set when a DMA transaction
begins and is unset when dmaengine_terminate_async function is called.
A new DMA transaction cannot be created if this flag is set.

Create a new function "stm32_usart_tx_dma_terminate" to be sure the flag
is unset after each call of dmaengine_terminate_async.

49a80424e3 serial: pl011: Drop redundant DTR/RTS preservation on close/open
Commit d8d8ffa477 ("amba-pl011: do not disable RTS during shutdown")
amended the PL011 serial driver to leave DTR/RTS polarity untouched on
tty close.  That change made sense.

But the commit also added code to save DTR/RTS state to an internal
variable on tty close and restore it on tty open.  That part of the
commit makes less sense:  The driver has no ->pm() callback, so the uart
remains powered after tty close and automatically preserves register
state, including DTR/RTS.

Saving and restoring registers isn't the job of the ->startup() and
->shutdown() callbacks anyway.  Rather, it should happen in ->pm().

Additionally, after pl011_startup() restores the state, the serial core
overrides it in uart_port_dtr_rts() if a baud rate has been set:

tty_port_open()
  uart_port_activate()
    uart_startup()
      uart_port_startup()
        pl011_startup()       # restores DTR/RTS from uap->old_cr
  tty_port_block_til_ready()
    tty_port_raise_dtr_rts    # if (C_BAUD(tty))
      uart_dtr_rts()
        uart_port_dtr_rts()   # raises DTR/RTS

The serial core also overrides DTR/RTS on tty close in uart_shutdown()
if C_HUPCL(tty) is set.  So a user-defined DTR/RTS polarity won't
survive a close/open cycle anyway, unless the user has set the baud rate
to zero and disabled hupcl on the tty.

Bottom line is, the code to save and restore DTR/RTS has no effect.
Remove it.

e368cc656f serial: pl011: Drop CR register reset on set_termios
pl011_set_termios() briefly resets the CR register to zero, thereby
glitching DTR/RTS signals.  With rs485 this may result in the bus being
occupied for no reason.

Where does this register write originate from?

The PL011 driver was forked from the PL010 driver in 2004:
https://git.kernel.org/history/history/c/157c0342e591

Until this commit, the PL010 driver's IRQ handler ambauart_int()
modified the CR register without holding the port spinlock.

ambauart_set_termios() also modified that register.  To prevent
concurrent read-modify-writes by the IRQ handler and to prevent
transmission while changing baudrate, ambauart_set_termios() had to
disable interrupts.  On the PL010, that is achieved by writing zero to
the CR register.

However, on the PL011, interrupts are disabled in the IMSC register,
not in the CR register.

Additionally, the commit amended both the PL010 and PL011 driver to
acquire the port spinlock in the IRQ handler, obviating the need to
disable interrupts in ->set_termios().

So the CR register write is obsolete for two reasons.  Drop it.

truncate it into a uint32_t leading to incorrect calculated values.

Switch back to keeping the base value in struct snd_uac_chip which fits
easily into an int, meaning that the division can be done in two steps
with the divisor fitting safely into a uint32_t on both steps.

92ef98a4ca usb: dwc2: gadget: initialize max_speed from params
DWC2 may be paired with a full-speed PHY which is not capable of
high-speed operation.  Report this correctly to the gadget core by
setting max_speed from the core parameters.

Prior to commit 5324bad66f ("usb: dwc2: gadget: implement
udc_set_speed()") this didn't cause the hardware to be configured
incorrectly, although the speed may have been reported incorrectly.  But
after that commit params.speed is updated based on a value passed in by
the gadget core which may set it to a faster speed than is supported by
the hardware.  Initialising the max_speed parameter ensures the speed
passed to dwc2_gadget_set_speed() will be one supported by the hardware.

Fixes: 5324bad66f ("usb: dwc2: gadget: implement udc_set_speed()")

regulator: qcom_smd: Align probe function with rpmh-regulator
The RPMh regulator driver is much newer and gets more attention, which in
consequence makes it do a few things better. Update qcom_smd-regulator's
probe function to mimic what rpmh-regulator does to address a couple of
issues:

- Probe defer now works correctly, before it used to, well,
  kinda just die.. This fixes reliable probing on (at least) PM8994,
  because Linux apparently cannot deal with supply map dependencies yet..

- Regulator data is now matched more sanely: regulator data is matched
  against each individual regulator node name and throwing an -EINVAL if
  data is missing, instead of just assuming everything is fine and
  iterating over all subsequent array members.

- status = "disabled" will now work for disabling individual regulators in
  DT. Previously it didn't seem to do much if anything at all.

According to RM, the clock divider range is from 1 to 8, clock
prescaling ratio may be any power of 2 from 1 to 128.
So the supported divider is not all the value between

Create table for the supported divder and add function to
check the clock divider is available by comparing with
the table.
