Hello Amit and Thara,

Could you please take a look at this patch series when you have some
time?  It hasn't received any feedback yet after being sent out on
1/24/2023.

According to the MAINTAINERS files, you are the maintainers for all
files in the drivers/thermal/qcom/ directory:

QUALCOMM TSENS THERMAL DRIVER
M:	Amit Kucheria <amitk@...nel.org>
M:	Thara Gopinath <thara.gopinath@...il.com>
L:	linux-pm@...r.kernel.org
L:	linux-arm-msm@...r.kernel.org
S:	Maintained
F:	Documentation/devicetree/bindings/thermal/qcom-tsens.yaml
F:	drivers/thermal/qcom/

Can you please check if this entry needs to be updated?  The
drivers/thermal/qcom directory now contains the qcom-tsens driver as
well as three other independent QCOM thermal drivers:
qcom-spmi-temp-alarm, qcom-spmi-adc-tm5, and lmh.

Thanks,
David
