[RESEND,v6,0/8] MediaTek Helio X10 MT6795 - Clock drivers

Message

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This (very big) series introduces system clock, multimedia clock drivers
(including resets) for this SoC.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.

  dt-bindings: mediatek: Document MT6795 system controllers bindings
  dt-bindings: clock: Add MediaTek Helio X10 MT6795 clock bindings
  dt-bindings: reset: Add bindings for MT6795 Helio X10 reset
    controllers
  dt-bindings: clock: mediatek: Add clock driver bindings for MT6795
  clk: mediatek: clk-apmixed: Remove unneeded __init annotation
  clk: mediatek: Export required symbols to compile clk drivers as
    module
  clk: mediatek: clk-apmixed: Add helper function to unregister
    ref2usb_tx
  clk: mediatek: Add MediaTek Helio X10 MT6795 clock drivers

I've queued this series up here [1] and will send a pull request to
the clock maintainer later this week.
