Commit 06e8935feb ("optimized SDIO IRQ handling for single irq")
introduced some spurious calls to SDIO function interrupt handlers,
such as when the SDIO IRQ thread is started, or the safety check
performed upon a system resume. Let's add a flag to perform the
optimization only when a real interrupt is signaled by the host
driver and we know there is no point confirming it.

Currently performance numbers are captured for each SDCC
transfers unconditionally which may add the overhead and
could reduce the SDCC read/write throughput numbers.
This change adds additional control for enabling/disabling the
capturing of performance numbers at runtime. We already have sysfs
entry named "perf" for msm sdcc devices. Currently setting this
entry to 0 clears the performance statistics. But now we are
changing the definition of this entry as mentioned below:
Disable performance capturing and clear the performance statistics:
"echo 0 > /sys/devices/platform/msm_sdcc.<n>/perf"
Enable performance capturing:
"echo 1 > /sys/devices/platform/msm_sdcc.<n>/perf"

MMC core reads SEC_COUNT information from EXT_CSD register and assumes
that the card supports sector access mode. Some eMMC cards (<=2GB) do not
support this mode even though they have SEC_COUNT value defined, causing
failure while populating extended partitions. Sector/Byte access mode
information is stored in OCR register. Hence, read OCR bit 30 and then
confirm it with SEC_COUNT value to know whether the card supports sector
access mode or byte access mode.

Part of commit d44455a0b838b1d691e63913f0b159552ac01803 introduced
a regression affecting resume behavior in that the controller's system
resume callback is being followed by an immediate runtime suspend; if
the system resume was caused by an OTG event, there would be a pending
runtime resume in the state machine function, which might fail due to
this race, causing the PHY to be unnecessarily reset.
This patch limits the actual hardware resumes to happen only when needed.
If a possible wakeup event such as VBUS or ID interrupt occurs while
in system suspend, don't allow runtime resume to execute in the wakeup
handler but rather defer the resuming to the system resume callback.
Also by incrementing the PM runtime usage counter within the system
resume, it may help prevent the premature runtime suspend from happening
immediately afterward. Otherwise, if there is no such OTG event, and
the controller is not a suspended host, do nothing.
If the bus is instead runtime suspended (and not system suspended) when
a wakeup event occurs, then normal runtime resume will bring the
hardware out of low power mode.

Drivers need to specify their bandwidth requirements to
bus-scaling driver to get guaranteed bandwidth on fabrics.
USB hardware uses a single buffer to transfer data across the
bus. As a result USB performance is highly dependent on system
fabric frequency as USB controller continuously sends NAKs on
the USB BUS unless complete buffer is filled/drained to the memory.
Hence, request for high bus bandwidth as long as USB cable is
connected to improve USB throughput.

Synopsis 28nm PHY has two different circuits for detecting changes on
ID line. ID_DIG is designed for detecting ID_float vs ID_gnd. ID_ACA
is designed for detecting RID_A, RID_B, RID_C states. These are mutually
exclusive and enabling both circuits has undefined behavior. Enable
ID_ACA upon VBUS high or ID_gnd events to detect further ACA states.
ACA ID_GND threshold range is overlapped with OTG ID_FLOAT threshold range.
Hence PHY ID_DIG circuit can not be used for detecting ACA ID_GND. Use
PMIC ID circuit for detecting both OTG and ACA ID_GND.
Link controller can not generate PHY_ALT interrupt in host mode. But the
corresponding PHY register reflects the actual ID state. Hence implement
polling to read PHY register to detect ID_GND --> ID_A, ID_A --> ID_B
transitions. That means low power mode can not be allowed in host mode.
Also disallow suspending the device attached on the root hub. Otherwise
PHY is put into suspend state automatically upon setting SUSP bit in PORTSC
register.
Link controller can not generate asynchronous interrupt for ID_ACA changes
in low power mode. Hence disallow low power mode in ID_B and ID_C states.
USB_MSM_ACA is not selected by default. If it selected, ACA states can be
detected and low power mode is not allowed in host mode. Writing "enable"
to <debugfs>/msm_otg/aca enables ACA irrespective of USB_MSM_ACA selection.
This is meant for debugging only.
