[Patch v6 00/10] Qualcomm SCM Rework

From: Andy Gross

The following set of patches does a bit of rework on the existing
Qualcomm SCM firmware. The first couple of patches deals with turning
the current SCM into a platform driver. The next couple are cleanups
that make adding the 64 support a little easier. I added in a patch to
convert the scm-32 to use DMA streaming APIs.

I took Kumar's 64 bit support patch and modified it to use the arm_smccc
calls. This simplified things quite a bit.

Lastly, there are a few DT patches to add the firmware node for a couple of the
supported platforms.

Changes from v5:
* Added SCM DT nodes for APQ8064 and MSM8974
* Make core clk optional in probe
* Update commit messages to describe some of the changes in more detail
* Put back some of the SCM64 helper functions
* Fix other miscellaneous review comments

Changes from v4:
* Fix Documentation error
* Fix misc review comments

Changes from v3:
* Added compatibles for the specific platforms requiring one clock.
* All other platforms will use the generic binding that requires 3 clocks.

Changes from v2:
* Added use of streaming DMA APIs for scm-32.
* Changed DT binding to simplify compats.
* Removed Kconfig.platform change that selected QCOM_SCM for ARM64
* Fixed misc comments
* Changed init function to populate the device differently.
* Fixed missing of_node_put

Changes from v1:
* Changed binding to reflect proper firmware node usage
* Added arch_initcall to populate the firmware device, if present
* Fixed various review comments
* Removed extraneous includes from SCM 64 file.
