2019-04-20thermal: bcm2835: Fix crash in bcm2835_thermal_debugfsPhil Elwell1-5/+4
[ Upstream commit 35122495a8c6683e863acf7b05a7036b2be64c7a ] "cat /sys/kernel/debug/bcm2835_thermal/regset" causes a NULL pointer dereference in bcm2835_thermal_debugfs. The driver makes use of the implementation details of the thermal framework to retrieve a pointer to its private data from a struct thermal_zone_device, and gets it wrong - leading to the crash. Instead, store its private data as the drvdata and retrieve the thermal_zone_device pointer from it.

2019-02-12thermal: bcm2835: enable hwmon explicitlyMatthias Brugger1-0/+11
[ Upstream commit d56c19d07e0bc3ceff366a49b7d7a2440c967b1b ] By defaul of-based thermal driver do not enable hwmon. This patch does this explicitly, so that the temperature can be read through the common hwmon sysfs.

2018-07-03thermal: bcm2835: Stop using printk format %pCrGeert Uytterhoeven1-2/+2
commit bd2a07f71a1e2e198f8a30cb551d9defe422d83d upstream. 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.

2017-08-11thermal: bcm2835: constify thermal_zone_of_device_ops structuresJulia Lawall1-1/+1
The thermal_zone_of_device_ops structure is only passed as the fourth argument to thermal_zone_of_sensor_register, which is declared as const. Thus the thermal_zone_of_device_ops structure itself can be const. Done with the help of Coccinelle.

2017-07-01thermal: bcm2835: fix an error code in probe()Dan Carpenter1-1/+0
This causes a static checker because we're passing a valid pointer to PTR_ERR(). "err" is already the correct error code, so we can just delete this line.

2017-04-07thermal: broadcom: add Northstar thermal driverRafał Miłecki3-0/+114
Northstar is a SoC family commonly used in home routers. This commit adds a driver for checking CPU temperature. As Northstar Plus seems to also have this IP block this new symbol gets ARCH_BCM_IPROC dependency.
