The CG8 field of the CCM CCGR3 register is the 'mipi_core_cfg' gate clock,
according to the i.MX6q/sdl reference manuals. This clock is actually the
gate for several clocks, including the ipg clock's output. The MIPI DSI host
controller embedded in the i.MX6q/sdl SoCs takes the ipg clock as the pclk -
the APB clock signal . In order to gate/ungate the ipg clock, this patch adds
a new shared clock gate named as "mipi_ipg".

Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

Pull ARM SoC platform changes from Olof Johansson:
"New and updated SoC support. Also included are some cleanups where
the platform maintainers hadn't separated cleanups from new developent

Some of the larger things worth pointing out:
- A large set of changes from Alexandre Belloni and Nicolas Ferre
preparing at91 platforms for multiplatform and cleaning up quite a
bit in the process.
- Removal of CSR's "Marco" SoC platform that never made it out to the
market. We love seeing these since it means the vendor published
support before product was out, which is exactly what we want!
New platforms this release are:
- Conexant Digicolor (CX92755 SoC)
- Hisilicon HiP01 SoC
- CSR/sirf Atlas7 SoC
- ST STiH418 SoC
- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling
changes as cleanups vs new development -- which is a good sign that
we've come quite far on the cleanup effort. So over time we might
start combining the cleanup and new-development branches more"
