Subject: [PATCH v4 0/8] qcom: Add support for TSENS driver
Date: Fri,  9 Oct 2015 15:11:02 +0530	[thread overview]
Message-ID: <1444383670-32693-1-git-send-email-rnayak@codeaurora.org> (raw)

Patches 1/8 to 4/8 will need to go via the thermal tree/Eduardo.
Patches 5/8 to 8/8 will need to go via qcom-msm tree/Andy.

Eduardo, can you please take a look at the patches and let me
know if you see any issues.

Current set of patches apply on 4.3-rc4. Need to pull in clk-next
(for a dependent patch) to be able to test on ifc6410 board.

Changes since v3:
* Dropped 'clk: qcom: create virtual child device for TSENS' which
is picked up by Stephen
* Updated GCC bindings with optional TSENS properties

Changes since v2:
* Minor review fixes from Stephen/Punit and rebase on 4.3-rc4

Changes since v1:
* Created virtual tsens device from gcc driver for 8960,
with DT having a single node for gcc and tsens
* Minor fixes with rebasing on 4.3-rc1

Changes since RFC:
* Added support for 8916 and 8084
* Based off the latest nvmem framework patches [1]
* Minor review fixes for comments mostly from Lina

This is an attempt to have a single TSENS driver for
the different versions of the TSENS IP that exist, on
different qcom msm/apq SoCs'
Support is added for msm8916, msm8960 and msm8974 families.

A lot of the work is based of original code from Stephen Boyd
and Siddartha Mohanadoss. I have also picked some of what
Narendran Rajan did in his attempt to upstream the support
for 8960 family. I could not keep the original authorship on
any of the patches because I ended up moving the code around
quite a bit in an effort to have a single driver for the
various devices. I would be glad to change the authorship
for any of the patches if needed.
