Subject: [PATCH v5 0/5] Add LVTS support for mt8192

From: Bernhard Rosenkränzer <bero@...libre.com>

Add full LVTS support (MCU thermal domain + AP thermal domain) to MediaTek MT8192 SoC.
Also, add Suspend and Resume support to LVTS Driver (all SoCs),
and update the documentation that describes the Calibration Data Offsets.

v5 changes are a lot smaller than originally assumed -- commit
185673ca71d3f7e9c7d62ee5084348e084352e56 fixed the issue I
was originally planning to work around in this patchset,
so what remains for v5 is noirq and cosmetics.

Changelog:
   v5 :
        - Suspend/Resume in noirq stage
	- Reorder chipset specific functions
        - Rebased :
            base-commit: 4d5ab2376ec576af173e5eac3887ed0b51bd8566

   v4 :
        - Shrink the lvts_ap thermal sensor I/O range to 0xc00 to make
          room for SVS support, pointed out by
          AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>

    v3 :
        - Rebased :
            base-commit: 6a3d37b4d885129561e1cef361216f00472f7d2e
        - Fix issues in v2 pointed out by Nícolas F. R. A. Prado <nfraprado@...labora.com>:
          Use filtered mode to make sure threshold interrupts are triggered,
          protocol documentation, cosmetics
        - I (bero@...libre.com) will be taking care of this patchset
          from now on, since Balsam has left BayLibre. Thanks for
          getting it almost ready, Balsam!

    v2 :
        - Based on top of thermal/linux-next :
            base-commit: 7ac82227ee046f8234471de4c12a40b8c2d3ddcc
        - Squash "add thermal zones and thermal nodes" and
            "add temperature mitigation threshold" commits together to form
            "arm64: dts: mediatek: mt8192: Add thermal nodes and thermal zones" commit.
        - Add Suspend and Resume support to LVTS Driver.
        - Update Calibration Data documentation.
        - Fix calibration data offsets for mt8192
            (Thanks to "Chen-Yu Tsai" and "Nícolas F. R. A. Prado").
