In chipidea IP RTL, there is a very limited design for siTD, the detail
like below:
There is no Max Packet Size at siTD, so it uses one constant for both
Max Packet Size for packet and the packet size for the last transaction
when considering schedule.
If the ttctrl.ttha does not match against Hub Address field in siTD,
this constant is 188 bytes, else this constant is 1023 bytes.If the ttctrl.ttha is non-zero value, RTL will use 188 as this constant,
so it will lose the data if the packet size is larger than 188 bytes, eg,
if we playback a wav which format is 48khz, 16 bits, 2 channels, the
packet size will be 192bytes, but the controller will only send 188 bytes
for this packet, the noise will be heared using USB audio card.
The use case is single transaction, but higher frame rate.If the ttctr.ttha is zero value, we can send 1023 bytes within one
transaction, but the controller will not accept the coming tranaction
if it considers the schedule time is less than 1023 bytes. So the
limitation is we can't schedule as many as transactions within frame.
If the total bytes is already 256 bytes for previous transactions within
frame, it can't accept another transaction. The use case is multiple
transactions, but less frame rate.Signed-off-by: Peter Chen

If this property is not set, the max packet size is 1023 bytes, and if
the total of packet size for pervious transactions are more than 256 bytes,
it can't accept any transactions within this frame. The use case is single
transaction, but higher frame rate.If this property is set, the max packet size is 188 bytes, it can handle
more transactions than above case, it can accept transactions until it
considers the left room size within frame is less than 188 bytes, software
needs to make sure it does not send more than 90%
maximum_periodic_data_per_frame. The use case is multiple transactions, but
less frame rate.Signed-off-by: Peter Chen

This reverts commit e765bfb73ff7.
In the most of cases, we only use one transaction per frame and the
frame rate may be high, If the platforms want to support multiple
transactions but less frame rate cases like [1] and [2], it can set
"non-zero-ttctrl-ttha" at dts.[1] http://www.spinics.net/lists/linux-usb/msg123125.html

CMA region is a must to avoid the multile memory mapping
for the DMAed memory and also benifit the large continious
phisical memory allocation.The default value is depend on the target system design and
user cases definition. This is not suitable to put this into
the soc.dtsi, thus we put it into the board DTS.customer can override the value by changing cma size in DTS file.
Again, customer need set the CMA size correctly according to the
target system. The incorrectly CMA size can cause Linux kernel fail
to boot up.CMA disabled or CMA size set to zero is also not allowed.Signed-off-by: Jason Liu

add lpsr mode state for flexcan pins
Signed-off-by: Dong Aisheng
(cherry picked from commit 535699f47fbd7fb22a435ca2047560ee20687392) -
For MX7D LPSR mode, the controller will lost power and got the
configuration state lost after system resume back.
So we need to set pinctrl state again and re-start chip to do
re-configuration after resume.For wakeup case, we also need re-configure the chip in case the state
got lost. For interface is not up before suspend case, we don't need
re-configure as it will be configured by user later by interface up.Signed-off-by: Dong Aisheng

When playback mono wav with record in background, there will be some
nosie in the right dac channel. It seems that the ADC data has been
routed to the dac channel.The cs42888 have 8 dac channels, it's appropriate to mute the unused
dac channels, and the noise will disappear.Steps to reproduce this issue:

Do sanity check before calling mmc_force_remove.
BCM WiFi driver will call wifi_card_detect(false) if probe fails
due to no card exists on board.This is needed for Android BSP since Android has builtin WiFi drver
and some boards may not have WiFi cards pluged.
Then the kernel dump likes follows may appear.

MMC core pm_notify will re-detect card after system suspend/resume,
regardless of post-cd claim.
Since in current MMC implement, non-removeable card only detects once,
this will break post card detect which happens next.

With igore pm notify feature, MMC core will not re-detect card
after system suspend/resume. This is needed for some special cards
like Broadcom WiFi which can't work propertly on card re-detect
after system resume.Signed-off-by: Dong Aisheng

The root cause of these failures is related with a hardware
ERRATA (onComp2 flop power-up value is 1 instead of 0).
Preview patch c086763024a8117beaa8ea27ee88eaeafd03ef3e in issue
track #1105 is not a fully fix, here implement a DummyDraw to
workaround the hardware ERRATA.Signed-off-by: Richard Liu

Before entering LPSR mode, as GPC was set to STOP/DSM mode already,
the wfi loop after LPSR mode would cause system enter STOP/DSM mode
first, then SNVS will force PMIC_ON_REQ to low, as SNVS needs IPG
clock to be on before entering SNVS/LPSR mode, so we have to disable
STOP/DSM mode to make sure IPG clock is on before SNVS actually enters
LPSR mode.Signed-off-by: Anson Huang

In the lpddr3-arm2-m4 dts, the I2C1 is disabled, so PMIC is disabled,
the cpufreq is not support. As thermal driver is depended on cpufreq
driver, if cpufreq is not support, the tempmon device can be disabled.Signed-off-by: Bai Ping
