[PATCH v3 00/13] QorIQ TMU multi-sensor and HWMON support

From: Andrey Smirnov
Date: Mon Apr 01 2019 - 00:14:51 EST


Everyone:

This series contains patches adding support for HWMON integration, bug
fixes and general improvements (hopefully) for TMU driver I made while
working on it on i.MX8MQ.

Feedback is welcome!

Thanks,
Andrey Smirnov

Changes since [v2]

- Patches rebased on v5.1-rc1

Changes since [v1]

- Rebased on "linus" branch of
git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git
that included latest chagnes adding multi-sensors support

- Dropped

thermal: qoriq: Add support for multiple thremal sites
thermal: qoriq: Be more strict when parsing
thermal: qoriq: Simplify error handling in qoriq_tmu_get_sensor_id()

since they are no longer relevant

- Added

thermal: qoriq: Don't store struct thermal_zone_device reference
thermal: qoriq: Add local struct qoriq_sensor pointer
thermal: qoriq: Embed per-sensor data into struct qoriq_tmu_data
thermal: qoriq: Pass data to qoriq_tmu_register_tmu_zone() directly

to simplify latest codebase

- Changed "thermal: qoriq: Do not report invalid temperature
reading" to use regmap_read_poll_timeout() to make sure that
tmu_get_temp() waits for fist sample to be ready before
reporting it. This case is triggered on my setup if
qoriq_thermal is compiled as a module

[v1] lore.kernel.org/lkml/20190218191141.3729-1-andrew.smirnov@xxxxxxxxx
[v2] lore.kernel.org/lkml/20190222200508.26325-1-andrew.smirnov@xxxxxxxxx
