[RFC PATCH 0/3] Add Sensirion STS30 temperature sensor driver

From: Maxwell Doose

Hi all,

This patch adds support for the Sensirion STS30 family of temperature
sensor drivers. It currently supports single-shot non-clock stretched
readings as well as the entirety of the STS30 family.

I'm sending this as an RFC patch as I unfortunately do not have the
hardware right now. I have compile-tested it successfully and have done
a tad bit of testing on QEMU, with it properly registering with no
errors reported in dmesg. Unfortunately due to the way I had compiled
the kernel used to test the driver it did not expose the I2C bus to
userspace properly and I was not able to retrieve values from the
driver, but I can continue more testing over the next few days and am
happy to answer any questions anyone may have. Additionally, regarding
dmesg logs, I neglected to save them while in my testing, but as stated
previously, I can continue more testing over the next couple of days.
