Pull x86 platform driver updates from Andy Shevchenko:
- The USB Power Delivery discrete components now can be enumerated by
i2c-multi-instantiate driver via several resources under single ACPI
device node (ACPI ID is INT3515).
- Touchscreen support is added for the Mediacom Flexbook Edge 11.
- Mellanox driver got fixed due to updates in their firmware.
- The power management stub driver for AtomISP v2 is fixed in order to
support Intel Baytrail SoCs where same quirk is needed for S0ix to
work.
- Special key handling has been fixed for Favorites hotkey on Thinkpad,
and Screen LOCK on ASUS.
- Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been
updated to support this.
- Few cleanups related to debugfs have been made in Intel IPS and Intel
PMC drivers. Besides that Intel PMC has been extended to show more
detailed information about Latency Tolerance

The two different assignments for pkt_len are actually the same and
so the if statement is redundant and can be removed. Masking a u8
return value from inb() with 0xFF is also redundant and can also be
emoved.
Similarly, the two different outb calls are identical as the mask
of 0xff on the second outb is redundant since a u8 is being written,
so the if statement is also redundant and can be also removed.
Detected by CoverityScan, CID#1475639 ("Identical code for different
branches")
V2: Remove the if statement for the outb calls, thanks to David
Miller for spotting this.

After some investigation I figured out that recently added cleanup code
tries to call VLAN filtering de-initialization function which exist only
for newer hardware. Corresponding function pointer is not
set (== 0) for older hardware, namely these chips:
#define CHIP_NUM_57710 0x164e
#define CHIP_NUM_57711 0x164f
#define CHIP_NUM_57711E 0x1650
And I have one of those in my test system:
Broadcom Inc. and subsidiaries NetXtreme II BCM57711E 10-Gigabit PCIe [14e4:1650]
Function bnx2x_init_vlan_mac_fp_objs() from
drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.h decides whether to
initialize relevant pointers in bnx2x_sp_objs.vlan_obj or not.
This regression was introduced after v4.20-rc7, and still exists in v4.20
release.

i.MX PWM module's ipg_clk_s is for PWM register access, on most of i.MX
SoCs, this ipg_clk_s is from system ipg clock or perclk which is always
enabled, but on i.MX7D, the ipg_clk_s is from PWM1_CLK_ROOT which is
controlled by CCGR132, that means the CCGR132 MUST be enabled first
before accessing PWM registers on i.MX7D. This patch adds ipg clock
operation to make sure register access successfully on i.MX7D and it
fixes Linux kernel boot up hang during PWM driver probe.

This reverts commit 6d11023c345e369bcb9d5a68b271764e362c1f6e.
It causes issues with Guenter's test systems and since there seems to
not be any agreement about _why_ this is a problem, but reverting it
fixes things, let's revert until the root cause is found.

This converts the MTX-1 driver to grab a GPIO descriptor
associated with the device instead of using a resource with
a global GPIO number. Augment the driver and the boardfile.

Remove dead code related to internal IV generators, which are no longer
used since they've been replaced with the "seqiv" and "echainiv"
templates. The removed code includes:
- The "givcipher" (GIVCIPHER) algorithm type. No algorithms are
registered with this type anymore, so it's unneeded.
- The "const char *geniv" member of aead_alg, ablkcipher_alg, and
blkcipher_alg. A few algorithms still set this, but it isn't used
anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG.
Just hardcode "<default>" or "<none>" in those cases.
- The 'skcipher_givcrypt_request' structure, which is never used.

Pull SCSI fixes from James Bottomley:
"This is two simple target fixes and one discard related I/O starvation
problem in sd.
The discard problem occurs because the discard page doesn't have a
mempool backing so if the allocation fails due to memory pressure, we
then lose the forward progress we require if the writeout is on the
same device. The fix is to back it with a mempool"

The security implementation is too chatty. For example, the common case
is that security is not enabled / setup, and booting a qemu
configuration currently yields:
nvdimm nmem0: request_key() found no key
nvdimm nmem0: failed to unlock dimm: -126
nvdimm nmem1: request_key() found no key
nvdimm nmem1: failed to unlock dimm: -126
Convert all security related log messages to debug level.

The PM816 module is a versatile PMIC with many diverse functions
integrated, including, a watchdog.
This watchdog is subcomponent of the PON (Power On) peripheral,
in the same way as pwrkey/resin buttons.
It works with two timers (2-stages), the first one generates an
IRQ to the main SoC (APQ8016/MSM8916), the second one performs
the reset.
This driver expects the following device hierarchy:
[pm8916]->[pm8916-pon]->[pm8916-wdt]
It uses the pm8916 regmap to access PM8916 registers.
