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

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

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

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.

In .mdio_bus_phy_may_suspend(), there check netdev is NULL to judge to set
phy to suspend status.netdev is NULL has three cases:
- phy is not found
- phy is found, match to general phy driver
- phy is found, match to specifical phy driverCase 1: phy is not found, cannot communicate by MDIO bus.
Case 2: phy is found:
if phy dev driver probe/bind err, netdev is not __open__ status,
mdio bus is unregistered.
if phy is detached, phy had entered suspended status.
Case 3: phy is found, phy is detached, phy had entered suspended status.So, in here, it shouldn't set phy to suspend by calling mdio bus.
In i.MX6UL evk/arm2 board, if down the ethx interface and do suspend/resume,
system will hang. Because after ethx down all clocks are gated off, for general
phy driver, unbind the phy device, for specifical phy driver, no unbind the
device, and the original driver call mdio bus to set phy to suspend during
system suspend, so system will hang since there have mdio register access.
The patch can fix it.Signed-off-by: Fugang Duan

bcmdhd can't support removing host during suspend and
driver crash when detect card after resume due to no response

It looks bcmdhd has a special requirement to enumerate card

So implement post-cd feature to allow driver to detect card
as it wants, then we add back non-removable capability
to avoid MMC core to redetect card after resume.root@imx6qdlsolo:~# echo standby > /sys/power/state

Current driver do not clear the tuning related register setting,
this will impact the timing and let the card inserted later meet
CRC error.Take the DDR50 card as example, if plug out an SDR104 card and
then plug in this DDR50 card, we will meet the following error log:mmc2: new ultra high speed DDR50 SDHC card at address aaaa

After we put gadget disconnect and connect in id switch handling,
update power lost work accordingly.Acked-by: Peter Chen
Signed-off-by: Li Jun -
During system sleep, if we switch otg role from gadget to host, and host
vbus is directly controlled by ID signal, we will lose vbus drop event
after resume because the vbus is on both at system suspend and resume, so
we will miss gadget disconnect handling before start host role. This patch
is to fix it by adding gadget disconnect for this case.Acked-by: Peter Chen
