[PATCH v2 0/4] MSM8998 Multimedia Clock Controller

[Jeffrey Hugo]

The multimedia clock controller (mmcc) is the main clock controller for
the multimedia subsystem and is required to enable things like display and
camera.

Based upon the "Rewrite clk parent handling" series [1] to simplify handling
of the external clocks that feed into the MMCC.

Assumes the "orphan probe defer" change [2] so that exposing XO via the RPM is
safe for the UART in case of late probe per review comments.

Assumes the common clk_hw registration is in place from "Make common clk_hw
registrations" [3]

v2:
-Rebased on the "Rewrite clk parent handling" series and updated to the clk init
mechanisms introduced there.
-Marked XO clk as CLK_IGNORE_UNUSED to avoid the concern about the XO going away
"incorrectly" during late init
-Corrected the name of the XO clock to "xo"
-Dropped the fake XO clock in GCC to prevent a namespace conflict
-Fully enumerated the external clocks (DSI PLLs, etc) in the DT binding
-Cleaned up the weird newlines in the added DT node
-Added DT header file to msm8998 DT for future clients
