We found this bug occurs again on mx6 when running
CTS with ADB over USB. The system will hang without
any log, and screen a little mess.
It's proved to be a known USB IP issue: USB controller
may access a wrong address for the dTD and then hang.
Re enable this workaround to avoid any system unstability.

The current SDMA use the new DMA tranfer direction. But the UART still
uses the old. This cause the RX failed.
So use the new DMA transfer direction for UART.

- the root cause of this issue is during resume process, USB clock
is not turned on for this USB charger case so that the second
suspend is processed without USB clock, it cause system hang
- in udc resume process, at this situation, we should exit low
power mode to enable the b session valid intrrupt to close the
usb clock when detach from usb charger

This patch includes some of the clk enable/disable changes from rev2
Check the version of the HDMI IP to determine whether the fifo
threshold needs to be high. The i.Mx6dl version of the HDMI doesn't
need the workaround. All other parts of the workaround are used
for both parts for code simplicity.
----------------------------------------------------------
For i.Mxq, set the Threshold of audio fifo as: FIFO depth - 2 (fixed
and independent of the number of channels actually used).
Use unspecified length ahb bursts (using fixed INCRx will make the
audio dma fail).
Additionally and in order to get it working on all conditions it will
be necessary to run the following sw steps at startup of video and audio
(or when video changes or audio changes):
1-Configure AUD_N1 and AUD_CTS1 registers with final value and let the
AUD_N2, AUD_N3, AUD_CTS2 and AUD_CTS3 to 0s.
2-Configure start and end addresses of audio DMA registers.
3-Start DMA operation
4-Configure the AUD_CTS2 and AUD_CTS3 with the final value.
5-Configure the AUD_N2 and AUD_N3 with final value.

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.

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.

This patch changes IPUv3 fb probe function logic to
unblank the primary fb only by default so that the
secondary fb using IPU DP BG channel won't be unblanked
when system boot-ups. This avoids the HDMI fb(as the
secondary fb using IPU DP BG channel) is unblanked
accidentally without plugging in HDMI cable.

Subject: [PATCH 1/1] mmc: sdhci-esdhc-imx: Enable ADMA2
Eanble the ADMA2 mode for freescale esdhc imx driver, tested on MX25
3DS board, MX51 BBG board and MX53 LOCO board.
This patch is only used to enable the ADMA2 for MX51/53 platforms.
MX25/35 can't support the ADMA2 mode, set BROKEN_ADMA quirk on
MX25/35 platforms.
The ADMA mode supported or not can be distinguished by bit 20 of
the Capability Register (offset 0x40) in the FSL eSDHC module.
