thermal/drivers/brcmstb_thermal: Use max to simplify brcmstb_get_temp

2026-04-02T17:23:54+00:00

Use max() to simplify brcmstb_get_temp() and improve its readability. Since avs_tmon_code_to_temp() returns an int, change the data type of the local variable 't' from long to int. No functional changes. Signed-off-by: Thorsten Blum Signed-off-by: Daniel Lezcano Reviewed-by: Florian Fainelli Link: https://patch.msgid.link/20260402165616.895305-3-thorsten.blum@linux.dev

thermal/drivers/bcm2835: Use %pC instead of %pCn

BCM74110 uses a different process node compared to previous chips that requires a different equation, account for that. Signed-off-by: Florian Fainelli Link: https://lore.kernel.org/r/20250116193842.758788-3-florian.fainelli@broadcom.com Signed-off-by: Daniel Lezcano

thermal: Switch back to struct platform_driver::remove()

2024-11-13T15:17:57+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/thermal to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way make a few whitespace changes to make indention consistent.

thermal/drivers/brcmstb_thermal: Simplify with dev_err_probe()

2024-09-02T11:09:49+00:00

dev_err_probe() is used to log an error message during the probe process of a device. It can simplify the error path and unify a message template. Using this helper is totally fine even if err is known to never be -EPROBE_DEFER. The benefit compared to a normal dev_err() is the standardized format of the error code, it being emitted symbolically and the fact that the error code is returned which allows more compact error paths.

thermal/drivers/broadcom: Fix race between removal and clock disable

2024-07-15T11:31:40+00:00

During the probe, driver enables clocks necessary to access registers (in get_temp()) and then registers thermal zone with managed-resources (devm) interface. Removal of device is not done in reversed order, because: 1. Clock will be disabled in driver remove() callback - thermal zone is still registered and accessible to users, 2. devm interface will unregister thermal zone. This leaves short window between (1) and (2) for accessing the get_temp() callback with disabled clock. Fix this by enabling clock also via devm-interface, so entire cleanup path will be in proper, reversed order.
