Subject: [PATCH v2 00/19] iio: adc: at91-sama5d2_adc: add support for temperature sensor
Date: Tue, 28 Jun 2022 18:16:12 +0300 [thread overview]
Message-ID: <20220628151631.3116454-1-claudiu.beznea@microchip.com> (raw)
Hi,
The following series add support for temperature sensor available on
SAMA7G5.
Temperature sensor available on SAMA7G5 provides 2 outputs VTEMP and VBG.
VTEMP is proportional to the absolute temperature voltage and VBG is a
quasi-temperature independent voltage. Both are necessary in computing
the temperature (for better accuracy). Also, for better accuracy the
following settings were imposed when measusing the temperature:
oversampling rate of 256, sampling frequency of 10MHz, a startup time of
512 ticks, MR.tracktim=0xf, EMR.trackx=0x3.
For computing the temperature measured by ADC calibration data is
necessary. This is provided via OTP memory available on SAMA7G5.
Patches 1/19-4/19 provides some fixes.
Patches 5/19-16/19 prepares for the addition of temperature sensor
support.
Patch 17/16 adds the temperature sensor support.
Along with temperature sensor support I took the chance and added
runtime PM support in this series, too (handled in patch 19/19).
The rest of patches in this series are minor cleanups.
Thank you,
Claudiu Beznea
Changes in v2:
- addressed review comments
- with this, new patches were intruced in this series: 2/19, 4/19,
8/19, 9,19
- runtime pm support has been adapted to work also when CONFIG_PM
is not enabled
- collected tags
