Cover letter [RFC 0/7] qcom: Add support for tsens driver

Quoted 3 lines · Rajendra Nayak

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.

Thanks, I think the design looks good. Will take a look at the patches.

Support is added for msm8916, msm8960 and msm8974 families. Based on top of the latest eeprom framework patches [1]
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.
