This patch adds requesting of the clocks supplied on MCLK1, MCLK2 pins,
gating of the 32k clock is added to the arizona_clk32k_enable(),
arizona_clk32k_disable() helpers.
It's a temporary change until the CODEC's clock controller gets exposed
through the clk API and is helpful for board configurations where the
MCLK clocks are not provided by always on oscillators.

The X-Powers AXP806 is a new PMIC that is paired with Allwinner's A80
SoC, along with a master AXP809 PMIC.
This PMIC has a new register layout, and supports some functions not
seen in other X-Powers PMICs, such as master-slave mode, or having
multiple AXP806 PMICs on the same bus with address space extension,
or supporting both I2C and RSB mode. I2C has not been tested.
This patch adds support for the interrupts of the PMIC. A regulator
sub-device is enabled, but actual regulator support will come in a
later patch.

The X-Powers AXP806 PMIC has a new set of buck and LDO regulators, and
also a switch. The buck regulators support teaming into multi-phase
groups, with A+B, A+B+C, D+E groupings.
Some registers controlling DCDC converter work settings are at different
offsets. Deal with them as well.
Add support for this new variant.

Newer revisions of the ChromeOS EC add more events besides the keyboard
ones. So handle interrupts in the MFD driver and let consumers register
for notifications for the events they might care.
To keep backward compatibility, if the EC doesn't support MKBP event, we
fall back to the old MKBP key matrix host command.

Pull libnvdimm fixes from Dan Williams:
- Fix for the nd_blk (NVDIMM Block Window Aperture) driver.
A spec clarification requires the driver to mask off reserved bits in
status register. This is tagged for -stable back to the v4.2 kernel.
- Fix for a kernel crash in the nvdimm unit tests when module loading
is interrupted with SIGTERM. Tagged for -stable since validation
efforts external to Intel use the unit tests for qualifying
backports.
- Add a new 'size' sysfs attribute for the BTT (NVDIMM Block
Translation Table) driver to make it symmetric with the other
namespace personality drivers (PFN and DAX) that provide a size
attribute for indicating how much namespace capacity is lost to
metadata.
The BTT change arrived at the start of the merge window and has
appeared in a -next release. It can technically wait for 4.9, but it
is small, fixes asymmetry in the libnvdimm-sysfs interface, and
something I would have squeezed into the v4.8 pull request had it
arrived a few days earlier.

When nvme_delete_queue fails in the first pass of the
nvme_disable_io_queues() loop, we return early, failing to suspend all
of the IO queues. Later, on the nvme_pci_disable path, this causes us
to disable MSI without actually having freed all the IRQs, which
triggers the BUG_ON in free_msi_irqs(), as show below.
This patch refactors nvme_disable_io_queues to suspend all queues before
start submitting delete queue commands. This way, we ensure that we
have at least returned every IRQ before continuing with the removal
path.

According to UEFI 2.6 section 7.5.3, the capsule should be in contiguous
virtual memory and firmware may consume the capsule immediately. To
correctly implement this functionality, the kernel driver needs to vmap
the entire capsule at the time it is made available to firmware.
The virtual allocation of the capsule update has been changed from kmap,
which was only allocating the first page of the update, to vmap, and
allocates the entire data payload.

Original patch: https://lkml.org/lkml/2016/8/4/32
If riocm_ch_alloc() fails then we end up dereferencing the error
pointer.
The problem is that we're not unwinding in the reverse order from how we
allocate things so it gets confusing. I've changed this around so now
"ch" is NULL when we are done with it after we call riocm_put_channel().
That way we can check if it's NULL and avoid calling riocm_put_channel()
on it twice.
I renamed err_nodev to err_put_new_ch so that it better reflects what
the goto does.
Then because we had flipping things around, it means we don't neeed to
initialize the pointers to NULL and we can remove an if statement and
pull things in an indent level.

The particularities of this variant are:
- GPIO_XXX_LSB and GPIO_XXX_MSB memory locations are inverted compared
to other variants.
- There is no Edge detection, Rising Edge and Falling Edge registers.
- IRQ flags are cleared when read, no need to write in Status register.

This update allows to use registers map as following :
regs[reg_index + offset] instead of
regs[reg_index] + offset
This makes code clearer and will facilitate the addition of STMPE1600
on which LSB and MSB registers are respectively located at addr and addr + 1.
Despite for all others STMPE variant, LSB and MSB registers are respectively
located in reverse order at addr + 1 and addr.
For variant which have 3 registers's bank, we use LSB,CSB and MSB indexes
which contains respectively LSB (or LOW), CSB (or MID) and MSB (or HIGH)
register addresses (STMPE1801/STMPE24xx).
For variant which have 2 registers's bank, we use LSB and CSB indexes only.
In this case the CSB index contains the MSB regs address (STMPE 1601).

In order to prepare the ground to STMPE1600,
as STMPE1600's SYS_CTRL register has the same layout as
STMPE801 variant, unify STMPExxx_REG_SYS_CTRL_RESET/INT_EN/INT_HI
bit masks to more generic STMPE_SYS_CTRL_RESET/INT_EN/INT_HI

By cross-checking STMPE 610/801/811/1601/2401/2403 datasheets,
it appears that edge detection and rising/falling edge detection
is not supported by all STMPE variant:
GPIO GPIO
Edge detection rising/falling
edge detection
610 | X | X |
801 | | |
811 | X | X |
1600 | | |
1601 | X | X |
1801 | | X |
2401 | X | X |
2403 | X | X |
Rework stmpe_dbg_show_one() and stmpe_gpio_irq to correctly
take these cases into account.

Reset was only implemented for STMPE1801 variant despite
all variant have a SOFT_RESET bit.
For STMPE2401/2403/801/1601/1801 SOFT_RESET bit is bit 7
of SYS_CTRL register.
For STMPE610/811 (which have the same variant id) SOFT_RESET
bit is bit 1 of SYS_CTRL register.

As STMPE1801/1601/24xx has a SYS_CTRL register and
STMPE1601/2403 has even a SYS_CTRL2 register, add
STMPE_IDX_SYS_CTRL/2 and update driver code accordingly
This update prepares the ground for not yet supported STMPE1600
which share similar REG_SYS_CTRL register.

Patch 19a469a58720 ("drivers/perf: arm-pmu: Handle per-interrupt
affinity mask") added support for partitionned PPI setups, but
inadvertently broke setups using SPIs without the "interrupt-affinity"
property (which is the case for UP platforms).
This patch restore the broken functionnality by testing whether the
interrupt is percpu or not instead of relying on the using_spi flag
that really means "SPI *and* interrupt-affinity property".
