On i.MX6UL EVK board, we use a external GPIO DC regulator to control
the VDD_ARM_SOC_IN voltage, if default voltage is 1.4V when the system
is bootup. Per design team, when the highest setpoint freq is not
bigger than 528MHz, we can decrease this regulator voltage to 1.3V.
On i.MX6UL TO1.1, we add a 700MHz setpoint. When the highest setpoint
freq is 700MHz, the DC regulator should be at 1.4V to to cover the IR
drop.Signed-off-by: Bai Ping

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

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

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

Change SLV_DLY_TARGET to IC recommended value 0x7(4/1 cycle)
according to spec.
The old value 0x1 is not robust and may fail in some critical
circumstance.Signed-off-by: Dong Aisheng

When enable DDR, the clock factor definition is changed.
e.g. original 200Mhz will be changed to 100Mhz if set MIX_CTRL_DDREN bit.
So we need to update the clock setting for strobe dll to lock
the correct clock rate.Additionally we also need disable the clock before locking strobe dll.

Enable HW auto retuning when set SDHCI_CTRL_EXEC_TUNING and clear it

If HW supports SDHCI_TUNING_MODE_3 which is auto retuning, we won't
retune during runtime suspend and resume, instead we use Re-tuning
Request signaled via SDHCI_INT_RETUNE interrupt to do retuning and
hw auto retuning during data transfer to guarantee the signal sample
window correction.This can avoid a mass of repeatly retuning during small file system
data access and improve the performance.Signed-off-by: Dong Aisheng

We see CRCs with SLV_DLY_TARGET of 7 during driver runtime suspend/resume

It's caused by Broadcom WiFi driver will keep handling SDIO irq even after
the driver is already suspended.
This weird behavior will block the MMC host suspend during its irq
synchronize operation in free_irq(), then the system suspend is blocked
too and hanged.Add SDHCI_QUIRK2_SDIO_IRQ_THREAD for BCM WiFi to use kernel thread
to process sdio interrupts which won't block system suspend and process
freeze operation.Signed-off-by: Dong Aisheng

SDIO cards may need clock to send the card interrupt to host.
Thus, we get runtime pm when sdio irq is enabled to prevent the clock
resource is released and put it when sdio irq is disabled.This patch can allow sdio irq disable (mmc_signal_sdio_irq()) to be
called in interrupt context due to sdhci_runtime_pm_put() is atomic
safe.Signed-off-by: Dong Aisheng
