vbus power routine can be different based on platform. If vbus power
sequence is provided using platform data(pdata), disconnect of OTG cable
doesn't turn off the VBUS related regulators and required other
interfaces. This issue is seen as vbus_is_on variable remains always zero
for pdata based vbus routine, and msm_hsusb_vbus_power(motg, 0) doesn't
invoke the required vbus power routine. Hence update the vbus_is_on
variable based on return value of pdata based vbus routine. With this
change, it is mandatory that pdata based vbus routine should return the
success/failure result.

Moving regulators and gpio to board file
GPIO and regulators are usually different for OEM projects.
This will give them the flexibility to support multiple

BAM DMUX driver gives the data to the USB in work context and USB
is once again scheduling work for sending the data to the host.
This change avoid's the double work queue scheduling for the data
received from BAM DMUX, which might reduce the cpu usage and improve
the throughputs.

Till now, we are communicating only the amount of the current that
should be drawn by the PMIC for charging from the OTG driver through
power supply class driver. With this change, we notify the type of the
charger connected as well, so that userspace can benefit for dispalying
the charger type in the UI.

During the SDCC DMA transfer, if DMA transfer time is
long enough to do IDLE power collapse then system may
go into IDLE power collapse and once SDCC DMA transfer
is completed, system wakes up from Idle Power Collapse
due to SDCC DMA interrupt. But delay for waking up
from Idle Power collapse could be as large as 5 ms which
really degrades the overall read & write throughputs
for SD/eMMC/SDIO cards.
For example, following are the performance numbers with
eMMC card on MSM8960 platform with and without Idle Power
Collapse.
Idle Power collapse enabled:
LMDD Read throughput = ~14 MB/s
LMDD Write throughput = ~6 MB/s
Idle Power Collapse disabled:
LMDD Read throughput = ~25 MB/s
LMDD Write throughput = ~8 MB/s
So this change votes against the Idle power collapse by registering
with PM QOS about it's acceptable DMA latency when SDCC transfer is
active. This latency value is one more than the latency of SWFI
which means system can go into SWFI but not in any of the other
low power modes (including Idle power collapse).

When a non requested interrupt triggers, the genirq ends up calling
mask or mask_ack callback. This callback is expected to mask that
interrupt so it doesn't trigger us further.
There is a bug in the pm8xxx-irq driver where config[] entry for an
unrequested irq remains empty. So the mask or the mask_ack callback
ends up masking 0th interrupt.
Fix the mask and mask_ack callback to check if config[] is empty, if
so fill it in right then and mask the irq.
