The interrupt clear flag register is a "write 1 to clear" register.
So, only writing ones allows to clear flags:
- Replace buggy stm32_clr_bits() by a simple write to clear error flags
- Replace useless read/modify/write stm32_set_bits() routine by a
simple write to clear TC (transfer complete) flag.

PL011's ->flush_buffer() implementation releases and reacquires the port
lock. Due to a race condition here, data can end up being added to the
circular buffer but neither being discarded nor being sent out. This
leads to, for example, tcdrain(2) waiting indefinitely.
Process A Process B
uart_flush_buffer()
- acquire lock
- circ_clear
- pl011_flush_buffer()
-- release lock
-- dmaengine_terminate_all()
uart_write()
- acquire lock
- add chars to circ buffer
- start_tx()
-- start DMA
- release lock
-- acquire lock
-- turn off DMA
-- release lock
// Data in circ buffer but DMA is off
According to the comment in the code, the releasing of the lock around
dmaengine_terminate_all() is to avoid a deadlock with the DMA engine
callback. However, since the time this code was written, the DMA engine
API documentation seems to have been clarified to say that
dmaengine_terminate_all() (in the identically implemented but
differently named dmaengine_terminate_async() variant) does not wait for
any running complete callback to be completed and can even be called
from a complete callback. So there is no possibility of deadlock if the
DMA engine driver implements this API correctly.
So we should be able to just remove this release and reacquire of the
lock to prevent the aforementioned race condition.

Per Documentation/DMA-API-HOWTO.txt,
To unmap a scatterlist, just call:
dma_unmap_sg(dev, sglist, nents, direction);
.. note::
The 'nents' argument to the dma_unmap_sg call must be
the _same_ one you passed into the dma_map_sg call,
it should _NOT_ be the 'count' value _returned_ from the
dma_map_sg call.
However in the driver, priv->nent is directly assigned with value
returned from dma_map_sg, and dma_unmap_sg use priv->nent for unmap,
this breaks the API usage.
So introduce a new entry orig_nent to remember 'nents'.

hci_qca interfaces to the wcn3990 via a uart_dm on the msm8998 mtp and
Lenovo Miix 630 laptop. As part of initializing the wcn3990, hci_qca
disables flow, configures the uart baudrate, and then reenables flow - at
which point an event is expected to be received over the uart from the
wcn3990. It is observed that this event comes after the baudrate change
but before hci_qca re-enables flow. This is unexpected, and is a result of
msm_reset() being broken.
According to the uart_dm hardware documentation, it is recommended that
automatic hardware flow control be enabled by setting RX_RDY_CTL. Auto
hw flow control will manage RFR based on the configured watermark. When
there is space to receive data, the hw will assert RFR. When the watermark
is hit, the hw will de-assert RFR.
The hardware documentation indicates that RFR can me manually managed via
CR when RX_RDY_CTL is not set. SET_RFR asserts RFR, and RESET_RFR
de-asserts RFR.
msm_reset() is broken because after resetting the hardware, it
unconditionally asserts RFR via SET_RFR. This enables flow regardless of
the current configuration, and would undo a previous flow disable
operation. It should instead de-assert RFR via RESET_RFR to block flow
until the hardware is reconfigured. msm_serial should rely on the client
to specify that flow should be enabled, either via mctrl() or the termios
structure, and only assert RFR in response to those triggers.

Currently flow control is not working due to lpuart32_set_mctrl that is
clearing TXCTSE bit in all cases. This bit gets earlier setup by
lpuart32_set_termios.
As I read in Documentation set_mctrl is also not meant for hardware
flow control rather than gpio setting and clearing a RTS signal.
Therefore I guess it is safe to remove the whole code in
lpuart32_set_mctrl.
