Subject: [PATCH v3 00/30] IIO-based thermal sensor driver for Allwinner H3 and A83T SoC

Allwiner H3 and A83T SoCs have a thermal sensor, which is a large refactored
version of the old Allwinner "GPADC" (although it have already only
thermal part left in A33).

This patch tried to add support for the sensor in H3 and A83T based on

This Patchtseries was in the beginning based on Icenowy Zengs v4 patchseries [1]. Since we decided to merge the mfd driver into the GPADC this changed. So only one patch could be reused.

Patches that adds support for H5, A64, A80 and H6 SoCs are allready prepared,
and will be upstreamed if this patchseries is applied and the testing is done.

Sorry for delaying this.


changes since v2:
	* mfd driver is now merged into the gpadc driver
	* complete rework

changes since v1:
	* collecting all acks 
	* rewording commits/fix typos
	* move code in place where it is used
	* fix naming conventions of defines
	* clarify commits
	* update documentation to cover the new nvmem calibraion
	* change nvmem calibration
