commit b906c056b6023c390f18347169071193fda57dde upstream.

Multiplying the Memory Controller clock rate by the tick count results
in an integer overflow and in result the truncated tick value is being
programmed into hardware, such that the GR3D memory client performance is
reduced by two times.

Pull more ARM SoC updates from Olof Johansson:
 "A few updates that we merged late but are low risk for regressions for
  other platforms (and a few other straggling patches):

   - I mis-tagged the 'drivers' branch, and missed 3 patches. Merged in
     here. They're for a driver for the PL353 SRAM controller and a
     build fix for the qualcomm scm driver.

   - A new platform, RDA Micro RDA8810PL (Cortex-A5 w/ integrated
     Vivante GPU, 256MB RAM, Wifi). This includes some acked
     platform-specific drivers (serial, etc). This also include DTs for
     two boards with this SoC, OrangePi 2G and OrangePi i86.

   - i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K
     video playback offload). This is the first i.MX 64-bit SoC.

   - Some minor updates to Samsung boards (adding a few peripherals in
     DTs).

   - Small rework for SMP bootup on STi platforms.

   - A couple of TEE driver fixes.

   - A couple of new config options (bcm2835 thermal, Uniphier MDMAC)
     enabled in defconfigs"

Pull Devicetree updates from Rob Herring:
 "The biggest highlight here is the start of using json-schema for DT
  bindings. Being able to validate bindings has been discussed for years
  with little progress.

   - Initial support for DT bindings using json-schema language. This is
     the start of converting DT bindings from free-form text to a
     structured format.

   - Reworking of initrd address initialization. This moves to using the
     phys address instead of virt addr in the DT parsing code. This
     rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
     rebuilding of lots of files.

   - Fix stale phandle entries in phandle cache

   - DT overlay validation improvements. This exposed several memory
     leak bugs which have been fixed.

   - Use node name and device_type helper functions in DT code

   - Last remaining conversions to using %pOFn printk specifier instead
     of device_node.name directly

   - Create new common RTC binding doc and move all trivial RTC devices
     out of trivial-devices.txt.

   - New bindings for Freescale MAG3110 magnetometer, Cadence Sierra
     PHY, and Xen shared memory

Before things go out of hand, make it possible to pass
flags when requesting "own" descriptors from a gpio_chip.
This is necessary if the chip wants to request a GPIO with
active low semantics, for example.
