During initalization of wcn3990, we observed UART is reading some
stray bytes on the Rx line. This is logging Frame reassembly errors
on the serial console. This could be because of tristate of Tx line
of wcn3990 during boot up.
[ 176.929612] Bluetooth: hci_qca.c:qca_recv() hci0: Frame reassembly
This patch will help to stop frame reassembly errors while changing
the baudrate. This is because host send a change baudrate request
command to the chip with 115200 bps, Whereas chip will change their
UART clocks to the enable for new baudrate and sends the response
for the change request command
wcn3990 requires a power pulse to turn ON/OFF along with
regulators. Sometimes we are observing the power pulses are sent
out with some time delay, due to queuing these commands. This is
causing synchronization issues with chip, which intern delay the
chip setup or may end up with communication iss
During hci down we observed IBS sleep commands are queued in the Tx
buffer and hci_uart_write_work is sending data to the chip which is
not required as the chip is powered off. This patch will disable IBS
and flush the Tx buffer before we turn off the chip.

The below issues are found in the recent testing.
1. Observed device is not going into off state or not responding.
As wcn3990 require a power pulses to turn on the irrespctive of
igniting regulators, it was observed that power on or power off
pulses are not in sync with respective to
Latest qualcomm chips are not sending an command complete event for
every firmware packet sent to chip. They only respond with a vendor
specific event for the last firmware packet. This optimization will
decrease the BT ON time. Due to this we are seeing a timeout error
message logs on the console
This patch will update the baudrate change request wait time from
300 ms to 100 ms. When host sends the change baudrate request to
the controller, controller sets its clock and wait until the
clocks settle down. Here the Wait time is required for both
host and controller to be on sync.

In probe_gdrom(), the buffer pointed by 'gd.cd_info' is allocated through
kzalloc() and is used to hold the information of the gdrom device. To
register and unregister the device, the pointer 'gd.cd_info' is passed to
the functions register_cdrom() and unregister_cdrom(), respectively.

Currently, we check whether the hctx type is supported every time
in hot path. Actually, this is not necessary, we could save the
default hctx into ctx->hctxs if the type is not supported when
map swqueues and use it directly with ctx->hctxs[type].
We also needn't check whether the poll is enabled
Hi Jens
These two patches are small optimization for accessing the queue mapping
in hot path. It saves the queue mapping results into blk_mq_ctx directly,
then we needn't do the complicated bounce on queue_hw_ctx[] map[] and
mq_map[].

blk-mq: save queue mapping result into ctx
Currelty, the queue mapping result is saved in a two-dimensional
array. In hot path, to get a hctx, we need do following,
q->queue_hw_ctx[q->tag_set->map[type].mq_map[cpu]]
This looks not efficient. Actually, we could save the queue mapping
result into ctx directly with different hctx type, lik

I think you do this because ovl-2l and ovl share the same driver and the

Hi Linus,
Daniel collected a couple of pulls after I want on holidays, back for
a couple of days, so may as well send them out.
This has exynos and etnaviv work for 4.21.
exynos:
- plane alpha and blending configurability
etnaviv:
- mostly cleanups in prep for new features.

MP2 controllers have two separate busses, so may accommodate up to two I2C
adapters. Those adapters are listed in the ACPI namespace with the

DMA for more than 32 bytes transf
