* changes:
  mhi: core: provide an API to retrieve device failure reason
  ARM: dts: msm: add a name to the mhi controller node
  mhi: cntrl: qcom: add support to retrieve device failure reason
  mhi: core: add support for retrieving device failure reason

When device asserts, the subsystem failure reason from device
can be read via an external API using the name of the MHI
controller.

Add a name to the MHI controller node for identification
purposes so that any external API can attempt to get some
information.

If a serial console write occurred while a UART transmit command was
waiting for a done signal then no further data would be sent until
something new kicked the system into gear. If there is already data
waiting in the circular buffer we must re-enable the tx watermark so we
receive the expected interrupts.

Disable M_TX_FIFO_WATERMARK_EN after we've sent all data for a given
transaction so we don't continue to receive a flurry of free space
interrupts while waiting for the M_CMD_DONE notification. Re-enable the
watermark when establishing the next transaction.

Also clear the watermark interrupt after filling the FIFO so we do not
receive notification again prior to actually having free space.

Before commit a1fee899 ("tty: serial: qcom_geni_serial: Fix
softlock") the size of TX transfers was limited to the TX FIFO size,
and wrap arounds of the UART circular buffer were split into two
transfers. With the commit wrap around are allowed within a transfer.
The TX FIFO of the geni serial port uses a word size of 4 bytes. In
case of a circular buffer wrap within a transfer the driver currently
may write an incomplete word to the FIFO, with some bytes containing
data from the circular buffer and others being zero. Since the
transfer isn't completed yet the zero bytes are sent as if they were
actual data.

Handle wrap arounds of the TX buffer properly and ensure that words
written to the TX FIFO always contain valid data (unless the transfer
is completed).

Transfers were being divided into device FIFO sized (64 byte max)
operations which would poll for completion within a spin_lock_irqsave /
spin_unlock_irqrestore block. This both made things slow by waiting for
the FIFO to completely drain before adding further data and would also
result in softlocks on large transmissions.

This patch allows larger transfers with continuous FIFO additions as
space becomes available and removes polling from the interrupt handler.

In mdss_dsi_cmd_write, a failure in copying the cmds to
'string_buf' can cause an early return. In this case,
the 'pcmds->string_buf' won't be pointing to a valid
buffer. This can lead to use-after-free and memory leak.
To avoid this, assign the newly allocated buffer to
'pcmds->string_buf' after returning from krealloc call.
