2019-02-05thermal: broadcom: Add Stingray thermal driverPramod Kumar
Stingray SoC has six temperature sensor and those are configured, controlled and accessed to read temperature and update in DDR memory using m0 firmware. All six sensors has been given 4 bytes of memory in DDR to write temperature in millivolts. This thermal driver read temperature values from DDR because no direct access to sensors. Like this all temparature sensors are monitored and trips at critical temperature. If driver can't handle thermal runaways because of any unknown reason, then firmware in m0 Processor will handle.

2018-06-05thermal: bcm2835: Stop using printk format %pCrGeert Uytterhoeven
Printk format "%pCr" will be removed soon, as clk_get_rate() must not be called in atomic context. Replace it by printing the variable that already holds the clock rate. Note that calling clk_get_rate() is safe here, as the code runs in task context.

2017-10-31thermal: add brcmstb AVS TMON driverBrian Norris
The AVS TMON core provides temperature readings, a pair of configurable high- and low-temperature threshold interrupts, and an emergency over-temperature chip reset. The driver utilizes the first two to provide temperature readings and high-temperature notifications to applications. The over-temperature reset is not exposed to applications; this reset threshold is critical to the system and should be set with care within the bootloader. Applications may choose to utilize the notification mechanism, the temperature reading mechanism (e.g., through polling), or both.
