Re: [PATCH 5.10.y-cip 26/29] thermal/drivers: Add TSU driver for RZ/G2L

From: Biju Das <biju.das.jz@...>

commit 673c68bd48390dad01f7d17670de3e33b60860ac upstream.

The RZ/G2L SoC incorporates a thermal sensor unit (TSU) that measures the
temperature inside the LSI.

The thermal sensor in this unit measures temperatures in the range from
−40 degree Celsius to 125 degree Celsius with an accuracy of ±3°C. The
TSU repeats measurement at 20 microseconds intervals and automatically
updates the results of measurement.

The TSU has no interrupts as well as no external pins.

This patch adds Thermal Sensor Unit(TSU) driver for RZ/G2L SoC.
+ /* TSU repeats measurement at 20 microseconds intervals and
+ * ts_code_ave = (ts_code[0] + ⋯ + ts_code[7]) / 8
+ */
+ /* The temperature Tj is calculated by the formula
+ * Tj = (dsensor − calib1) * 165/ (calib0 − calib1) − 40
+ * where calib0 and calib1 are the caliberation values.
+ */
I'd avoid using non-ASCII characters where possible. ... is not that
much longer, and that symbol should really be -.

Also comments should start with /* on separate line, but that's really
