MT6351 is a new power management IC and it is used for mt6797 SoCs. To define
mt6351_regs for pmic register mapping and pmic_mt6351 for
accessing register.

mt6797 is a highly integrated SoCs, it uses mt6351 for power management.
This patch adds pwrap driver to access mt6351. Pwrap of mt6797 support
dynamic priority meichanism, sequence monitor and starvation mechanism
to make transaction more reliable.
A big change from V4 to V5 is we remove INT1 interrupt declaration since
it is only for debug purpose. The PWRAP_RDDMY, RESET and DCM can use legacy
setting, it is backwards compatible. The new caps flag declaration is not
needed, just remove it.

Add a reset line to enable USB3 core implemented in UniPhier SoCs.
This reuses only the reset operations in reset-simple, because
the reset-simple doesn't handle any SoC-dependent clocks and resets.
This reset line is included in the USB3 glue layer, and it's necessary
to enable clocks and deassert resets of the layer before using this
reset line.

This pull request contains Broadcom ARM/ARM64/MIPS SoCs drivers changes
for 4.19, please pull the following:
- Doug updates the low-level suspend/resume code for ARM SoCs to support
the latest rev B3.0 memory controllers found on newer chips with an
appropriate match structure to perform the correct entry sequencing
- Florian updates the Device Tree binding document for these memory
controllers to list all possible compatible strings that exist given
the supported memory controllers.
- Stefan adds the GET_THROTTLED firmware property value that is required
for the Rasperry Pi voltage monitoring driver and updates the
Raspberry Pi firmware driver accordingly to register such a device
using the HWMON subsystem. Finally he adds support for reporting under
voltage conditions using a specialized HWMON driver.

Instead of checking the return value of platform_get_resource(), we can
use devm_ioremap_resource() which has the NULL pointer check and the
memory region requesting. devm_ioremap_resource is designed to replace
calls to devm_request_mem_region followed by devm_ioremap, so let's use
the same.

This introduces support for the SRAM C1 section, that is controlled by
the system controller. This SRAM area can be muxed either to the CPU
or the Video Engine, that needs this area to store various tables (e.g.
the Huffman VLD decoding tables).
This only supports devices with the same layout as the A10 (which also
includes the A13, A20, A33 and other SoCs).

Following-up on the introduction of a new binding for the A64, this
introduces a system-control binding for the A10 as a replacement of
the sram-controller binding.
This change is motivated by consistency with the Allwinner literature,
that mentions system control over SRAM controller. Moreover, the system
control block is sometimes used for more than SRAM (e.g. for muxing
related to the ethernet PHY).

The Reset Controller should be registered in the end of probe, otherwise
Memory Controller device goes away if IRQ requesting fails and the Reset
Controller stays registered. To avoid having to unwind the MC probing in
a case of SMMU probe failure, let's simply print the error message without
failing the MC probe. This allows us to just move the Reset Controller
registering before the SMMU registration, reducing code churning. Also
let's not fail MC probe in a case of Reset Controller registration failure
as it doesn't prevent the MC driver to work.

In the quest to remove all stack VLA usage from the kernel[1], this
removes the VLA in favor of a maximum size and adds a sanity check.
Existing callers of the firmware interface never need more than 24
bytes (struct gpio_set_config). This chooses 32 just to stay ahead
of future growth.

Pull selinux fix from Paul Moore:
"One fairly straightforward patch to fix a longstanding issue where a
process could stall while accessing files in selinuxfs and block
everyone else due to a held mutex.
The patch passes all our tests and looks to apply cleanly to your
current tree"

selinux: move user accesses in selinuxfs out of locked regions

Pull block fixes from Jens Axboe:
"Small set of fixes for this series. Mostly just minor fixes, the only
oddball in here is the sg change.
The sg change came out of the stall fix for NVMe, where we added a
mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
sort-of ruins that, since we'd need to account for that. That's
actually a generic problem, since lots of drivers need to allocate SG
lists. So this just removes support for CONFIG_SG_DEBUG, which I added
back in 2007 and to my knowledge it was never useful.
Anyway, outside of that, this pull contains:
- clone of request with special payload fix (Bart)
- drbd discard handling fix (Bart)
- SATA blk-mq stall fix (me)
- chunk size fix (Keith)
- double free nvme rdma fix (Sagi)"
* tag 'for-linus-20180629' of git://git.kernel.dk/linux-block:
sg: remove ->sg_magic member
drbd: Fix drbd_request_prepare() discard handling
blk-mq: don't queue more if we get a busy return
block: Fix cloning of requests with a special payload
nvme-rdma: fix possible double free of controller async event buffer
block: Fix transfer when chunk sectors exceeds max
