commit a89b94b53371bbfa582787c2fa3378000ea4263d upstream.
We're currently emulating the vbus and id interrupts in the OTGSC
read API, but we also need to make sure that if we're handling
the events with extcon that we don't enable the interrupts for
those events in the hardware. Therefore, properly emulate this
register if we're using extcon, but don't enable the interrupts.
This allows me to get my cable connect/disconnect working
properly without getting spurious interrupts on my device that
uses an extcon for these two events.

commit f60f8ccd54e03c1afafb2b20ceb029a0eaf7a134 upstream.
With the id and vbus detection done via extcon we need to make
sure we poll the status of OTGSC properly by considering what the
extcon is saying, and not just what the register is saying. Let's
move this hw_wait_reg() function to the only place it's used and
simplify it for polling the OTGSC register. Then we can make
certain we only use the hw_read_otgsc() API to read OTGSC, which
will make sure we properly handle extcon events.

commit 68abfb8015832ddf728b911769659468efaf8bd9 upstream.
Caching the fault register after a single I2C read may not keep an accurate
value.
Fix by doing two reads in irq_handle_thread() and using the cached value
elsewhere. If a safety timer fault later clears itself, we apparently don't get
an interrupt (INT), however other interrupts would refresh the register cache.
From the data sheet: "When a fault occurs, the charger device sends out INT
and keeps the fault state in REG09 until the host reads the fault register.
Before the host reads REG09 and all the faults are cleared, the charger
device would not send any INT upon new faults. In order to read the
current fault status, the host has to read REG09 two times consecutively.
The 1st reads fault register status from the last read [1] and the 2nd reads
the current fault register status."
[1] presumably a typo; should be "last fault"

Currently the opal_exit tracepoint usually shows the opcode as 0:
<idle>-0 [047] d.h. 635.654292: opal_entry: opcode=63

kopald-1209 [019] d... 636.420959: opal_exit: opcode=0 retval=0
This is because we incorrectly load the opcode into r0 before calling
__trace_opal_exit(), whereas it expects the opcode in r3 (first function
parameter). In fact we are leaving the retval in r3, so opcode and
retval will always show the same value.
Instead load the opcode into r3, resulting in:
<idle>-0 [040] d.h. 636.618625: opal_entry: opcode=63

commit 5008efc83bf85b647aa1cbc44718b1675bbb7444 upstream.
The PJ4 inline asm sequence to write to cp15 cannot be built in Thumb-2
mode, due to the way it performs arithmetic on the program counter, so it
is built in ARM mode instead. However, building C files in ARM mode under
CONFIG_THUMB2_KERNEL is problematic, since the instrumentation performed
by subsystems like ftrace does not expect having to deal with interworking
branches.
Since the sequence in question is simply a poor man's ISB instruction,
let's use a straight 'isb' instead when building in Thumb2 mode. Thumb2
implies V7, so 'isb' should always be supported in that case.

KERNEL_TEXT_RDONLY is similar to DEBUG_RODATA, but it relies on
4k pages to be made, whereas DEBUG_RODATA can work with or
without 4k pages. Let's move the depends on statement from
FORCE_PAGES to KERNEL_TEXT_RDONLY to accurately reflect the real
dependency here. This fixes a warning where we have FORCE_PAGES
enabled but DEBUG_RODATA is also enabled at the same time because
the latter is "default y" now and the depends on for FORCE_PAGES
can't be satisfied. In fact, it's OK for FORCE_PAGES to be
enabled at the same time as DEBUG_RODATA, it's really there to
prevent KERNEL_TEXT_RDONLY being enabled at the same time as
DEBUG_RODATA. Move the depends on to make things clearer.

As reported by kernelci, we get a harmless warning in this driver
when CONFIG_PM is disabled:
net/rfkill/core.c:810:12: warning: 'rfkill_resume' defined but not used [-Wunused-function]
net/rfkill/core.c:800:12: warning: 'rfkill_suspend' defined but not used [-Wunused-function]
This marks the functions as __maybe_unused to remove the #ifdef, and uses
a conditional reference to the pm operations instead, which will work
in any combination.
The patch is needed for both android-common-4.9 and 4.4.

When the USB_ID line is pulled low for a very short time there is a
possibility that the SW misses rising edge(removal) event. This may
lead to the state where charger is stuck in the boost-mode forever.
Fix this my adding a SW based glitch logic which checks for the
USB_ID after a SW debounce time and then notifies its presence/removal to
the USB driver.

Current implementation of SPMI arbiter dispatches interrupt based on the
Arbiter's accumulator status, in some cases the accumulator status may
remain zero and the interrupt remains un-handled. Add logic to dispatch
interrupts based Arbiter's IRQ status if the accumulator status is zero.

In case of emmc5.0 cards where HS400 mode and CMD5(awake) partial
init is enabled -> mmc_partial_init is broken and gives below errors.
Fix this by adding calibration logic in case of HS400 mode.
NOTE: In HS400 mode tuning is only performed once during bootup (in
HS200 mode).
Post to that it is always DLL calibration which is performed (in
system/runtime resume).
So even for below issue since timing is already changed using
cached_ios, then do the calibration using ->execute_tuning.

For a BADD 3.0 device, the Data Endpoint wMaxPacketSize
of an Alt Setting must be one of the values mentioned in
the specifications. Similarly, the unit IDs of the source
units of any entity is prescribed by the specs. Add
support for checking the error(default) branches in the
relevant switch cases and accordingly handle them.

Protect polling interval update event in the governor
with mutex lock.
This will avoid parallel execution of update interval event
on different cores, resulting in memory poison overwritten.

There could be clocks where the clock operations of set_rate_and_parent
would be defined to take care of setting rate and updating parent.
Move the vdd voting logic to ensure the vdd levels are voted prior to
updating rate and parent.

and lrbp->cmd is explicitly dereferenced without
checking NULL. Fix them by initializing cmd_id with
an initial value 0 and checking NULL for lrbp->cmd.
