Subject: [PATCH v4 0/2] Global Clock Controller driver for MSM8976/56

This is the Global Clock Controller (GCC) driver for MSM8956, MSM8976
and APQ variants and it has been tested on two Sony phones featuring the
Qualcomm MSM8956 SoC.

In addition to GCC this driver is also responsible for providing MDSS
and GFX3D clocks which reside in the same register space.

SoMainline is dedicated to getting their long-awaited msm8976 support,
including the Xperia X, X Compact and if feasible also the Xperia Touch
projector (APQ8056) slowly but steadily upstreamed.

Changes since v3:
- Set the enable_mask of gcc_apss_ahb_clk and gcc_apss_axi_clk to BIT 14
  and 13 respectively instead of overlapping gcc_crypto_ahb_clk's BIT 0.

Changes since v2:
- Rebased on v5.14;
- Various minor cleanups (lowercase hex, const where appropriate,
  removal of unused enum constants);
- Fixed XOR confusion in probe;
- All remnants of global clock name dependencies are removed, all
  inter-driver dependencies must be fully specified in DT;
- Added proper dt-bindings yaml validation, listing the required clocks;
- Moved dt-bindings header to the dt-bindings patch.

Changes since v1:
- Rebased onto linux-next 20191015
- Fixed platform driver name (qcom,gcc-8976 => gcc-msm8976)
- Splitted changes to dt-bindings to a separate commit
