ESAI can call ASRC for sample rate convert if the input sample rate
is not support.
1 ESAI will decide whether to use ASRC for sample rate convert in
imx-cs42888.c. If ASRC is need, the asrc_enable will be set.
2 In imx-pcm-dma-mx2.c, according to the value of asrc_enable, the
dma driver would decide whether to alloc another p2p dma channel to
support MEMORY-->ASRC_INPUT-->ASRC_OUTPUT-->ESAI_TX_FIFO route.
3 The code support 2 channel,24/32 bit audio file playback.

The issue is hard to reproduce in normal envrionment. And
the reproduce rate is about 40% when doing VTE auto test.
while the driver did report being busy when the link is down
or no transmission buffers are available, it did not stop the
queue, causing instant retries. furthermore, transmission being
triggered with link down was caused by unconditional queue
wakes, especially on timeouts.
Now, wake queue only if link is up and transmission buffers
are available, and dont forget to wake queue when link has
been adjusted. next, add stop queue notification upon driver
induced transmission problems, so network stack has a chance
to handle the situation.

Declaring strings in assembler source involves a certain amount of

Encapsulating this boilerplate in a macro should help to avoid some

SYSRQ is very useful for kernel debug thus enable it by default.
SYSRQ support serial port, we can send the command via minicom:
CTRL A + F (send BRK) + T: to dump the task information

imx_rxint -> spin_lock_irqsave(&sport->port.lock, flags);
And then it will call the following functions:
uart_handle_sysrq_char -> handle_sysrq -> printk ->
__call_console_write_drivers -> imx_console_write ->
Here the imx_console_write function will call:
spin_lock_irqsave(&sport->port.lock, flags);
The A-A deadlock happens. We need spin_unlock before handle sysrq char
and spin_lock again after it.

The imx UART hardware controller can identify BREAK character and the
imx_set_termios() can accept BRKINT set by users, but current existing
imx_rxint() can't pass BREAK character and TTY_BREAK to the tty layer
as other serial drivers do (8250.c omap_serial.c).
Here add code to handle BREAK character and pass it to tty layer.
To detect error occurrence, i use URXD_ERR to replace (URXD_OVRRUN |
URXD_FRMERR | ...) because any kind of error occurs, URXD_ERR will
always be set to 1.
I put the URXD_BRK to the first place to check since when BREAK error
occurs, not only URXD_BRK is set to 1, but also URXD_PRERR and
URXD_FRMERR are all set to 1. This arrangement can filter out fake
parity and frame errors when BREAK error occurs.

- Built in gadget device driver, plug in USB cable with no response,
the reason is USB VBUS wakeup is not enable after OTG switch,make
sure pdata->port_enables is 1 even if the pdata is otg device pdata.
-Without modprobe or built in gadget device driver,after plug out
the USB otg cable,will output "wait otg vbus change timeout!".The
reason is we get error otgsc data after USB enter low power mode.

commit 73736e0387ba0e6d2b703407b4d26168d31516a7 upstream.
Zhihua Che reported a possible memleak in slub allocator on
CONFIG_PREEMPT=y builds.
It is possible current thread migrates right before disabling irqs in
__slab_alloc(). We must check again c->freelist, and perform a normal
allocation instead of scratching c->freelist.
Many thanks to Zhihua Che for spotting this bug, introduced in 2.6.39
V2: Its also possible an IRQ freed one (or several) object(s) and
populated c->freelist, so its not a CONFIG_PREEMPT only problem.
