msm: kgsl: generate descriptive names for kgsl-timeline

Generate names for kgsl-timelines using the following format:
<device>-<thread name>(<tid>)-<proc name>(<pid>)-<context id>

This makes it possible to identify the context of a timeline in the
sync dump, which makes it much easier to identify which context has
a GPU timeout.

msm: rotator: Add proper checks for enabling Fast YUV

For rotator version 2.0 and above, there is support for fast
YUV which gives better rotator performance. However, there are
few constraints related to height under which fast YUV cannot be
enabled when 90 degree rotation is enabled. Make sure
to add proper checks before enabling fast YUV.

msm_serial_hs: Improve UART Shutdown path

For uart port close operation, serial core calls msm_hs_stop_rx_locked()
which sends discard flush request to ADM driver after changing rx.flush
state machine from FLUSH_NONE to FLUSH_STOP value. Next serial core
calls msm_hs_shutdown()and it waits for discard flush completion with
rx.flush state machine to be set as FLUSH_SHUTDOWN to complete uart
port close operation. With this approach, transfer termination is not
known by UART Core which may still allow UART core to make CRCI request
with ADM Core if new data is being received from remote uart. Hence
invoke Force RxStale from msm_hs_stop_rx_locked() which informs UART
core to terminate current Rx transfer and do not make any new CRCI
request with ADM core for any new incoming data. On receiving RxStale
interrupt, it sends discard flush request to ADM driver to terminate
transfer with ADM hardware.

This new programming sequence is required to get both UART and ADM
hardwares in-sync for termination of transfer.

msm_serial_hs: Fixing issue during UART shutdown

During UART port close in msm_hs_shutdown(), flag is_shutdown is
set as true and then UART interrupt is disabled and UART irq line
is freed. This is causing corner case in which even if uart shutdown
is in progress, UART interrupt can come as the UART interrupt is not
disabled and UART irq line not freed at this point. As flag
is_shutdown is set as true in msm_hs_shutdown() and then if UART
interrupt comes, it is hitting BUG_ON in UART Interrupt handler
msm_hs_isr(). To fix this issue, disable the UART irq and free
the UART irq line at the beginning of the msm_hs_shutdown() and
then set the flag is_shutdown.

In msm_hs_shutdown, disabling UART Interrupt and setting flag
is_shutdown is done with uart spinlock acquired. There is a
possibility that on other core, msm_hs_isr() might need to wait
for the same uart spinlock and later when msm_hs_isr() is executed
BUG_ON is hit. As by this time all UART Interrupt is disabled,
hence removing the BUG_ON and instead keep prints to notify the
same.

msm_serial_hs: Use RFR GPIO to communicate remote uart

CTS and RFR GPIOs are used for hardware flow control between
two uarts. RFR GPIO provides current status of uart receiver
to remote uart and based on this remote uart sends data.
Hence use this functionality to prevent remote uart to send
data when port is being opened, baud rate change operation
is in progress and port is being closed.

This change also set UART_DM_MR2 (Bit: 8 and 9) before
configuring connected UART GPIOs to prevent RX_BREAK character
and any character having PARTIY or FRAMING error which can be
generated due to configuration of those GPIOs. Allows those
character once port is opened successfuly.

This change also zeroed uart rx software buffer which would
help to see how many bytes copied by ADM from received data
with UART RX FIFO to this memory. This would be useful if
there is any Rx Stall issue is seen.
