Subject: [PATCH v8 0/4] MSM8998 Multimedia Clock Controller

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

v8:
-drop dts changes from series per Stephen's request
-fix the mislabeled mmcc example
-drop Stephen as maintainer of the mmcc binding

v7:
-port to gcc.yaml.  Drop reviewed-by for DT changes as they got completely
rewritten
-drop "clk: qcom: smd: Add XO clock for MSM8998".  Will need to find another
solution and this is not blocking right now
-convert mmcc to yaml
-drop errant clk.h include
-use blank entries in the DT when no clock is available

v6:
-drop clk_get from mmcc clock provider

v5:
-handle the case where gcc uses rpmcc for xo, but the link is not specified in dt
-have gcc select rpmcc

v4:
-fix makefile to use correct config item
-pick up tags
-fix ordering of clocks and clock-names in dt
-drop MODULE_ALIAS
-wait for xo in mmcc since that was found to be useful in some debug configs

v3:
-Rebase onto linux-next to get the final version of the clk parent rewrite
series
-Moved the bindings header to the bindings patch per Rob
-Made xo manditory for GCC to work around the lack of clk orphan probe defer
to avoid the uart console glitch

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

Jeffrey Hugo (4):
  dt-bindings: clock: Document external clocks for MSM8998 gcc
  dt-bindings: clock: Convert qcom,mmcc to DT schema
  dt-bindings: clock: Add support for the MSM8998 mmcc
  clk: qcom: Add MSM8998 Multimedia Clock Controller (MMCC) driver
