This is an initial driver for the new QPIC based NAND controller(NANDc)
that is introduced in MDM9x25. This driver has been leveraged from the
current driver msm_nand.c and is modified for the new hardware changes
in QPIC NANDc. Addition of SPS/BAM support is one of the major
hardware changes in new controller. It also supports only BCH ECC and
based on the device capabilities either 4 bit or 8 bit BCH ECC will
be used. This driver is based on the device tree architecture.

In mmc_wait_for_req_done() function, change the call wait_for_completion()
to wait_for_compltion_io(). This change makes the kernel account for
wait time as I/O wait and through another configuration, this io wait
is treated as busy which makes the acpu clock to scale up.

We see a kernel panic when we reboot with recovery mode
from the UI. Though kernel prepares to stop the other
cores(cpu_relax), but in some race condition mpdecision kicks
in to wake up(CPU_UP_PREPARE) the other core, before we go
ahead for issuing pcom command from core-0 for restart and this
causes a BUG in stop machine code.
So to resolve this before we issue a PCOM_RESET_CHIP command from
core-0, we must ensure that IRQ and FIQ is disabled and also
map the user pages to 1:1 mapping so as to not have unpredictable
MMU errors or kernel panics.
Moving the code put of pm2.c as this code is more restart specific and
not related to power management code.

The peripheral registrations are stored in a table
on apps processor. During SSR, these need to be deleted
and fresh ones are recorded after SSR completes. Currently
this clean up function is called from interrupt context.
This cleanup function works on a shared table, which is
protected by mutexes. Using this mutex in interrupt function
causes bug with spinlocks and generates warnings. Moving this
cleanup to work queue resolves the issue.
However, there might be race condition with this move. A new
registration might come in, while the clean up is still going on
OR yet to begin. Adding a bit mask which tracks the peripheral
undergoing SSR. if new registration is received from this processor
before clean up is completed, the registration packet is dropped.
Also, an error message is printed in kernel to notify of the drop.

The QPNP VADC driver supports the User Bank Peripheral of
the voltage ADC(VADC).
VADC is a 15 bit ADC that measures signals through the
Main analog multiplexer (AMUX) and PREMUX. The driver
arbitrates the request to issue ADC read requests.
VADC driver includes support for the conversion sequencer.
The conversion sequencer is a HW triggered signal to start
ADC measurement on trigger events for PA ON,
camera flash and TX threshold.
The AMUX supports external pull-ups simultaneously. Clients
can select the appropriate AMUX input channel to measure the
ADC for the intended pull up configuration.

bam_dmux_log() takes a formatted string and a variable argument list
similar to printf() and creates printf() style output to a private kfifo
log. This change fixes a particular invocation of bam_dmux_log() which has
an invalid variable argument list for the formatted string used. Depending
on system timing, this invocation could succeed as expected, or it could
cause a null pointer exception.
To prevent further issues, add the __printf() function attribute so that
the gcc compiler will check at compile time the arguments to bam_dmux_log()
for proper number and types according to printf() usage.
