Subject: [Patch v4 0/8] Qualcomm SCM Rework
Date: Wed, 11 May 2016 09:15:50 -0500 [thread overview]
Message-ID: <1462976158-26016-1-git-send-email-andy.gross@linaro.org> (raw)
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 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.
