2022-04-20thermal: int340x: Increase bitmap sizeSrinivas Pandruvada1-1/+1
commit 668f69a5f863b877bc3ae129efe9a80b6f055141 upstream. The number of policies are 10, so can't be supported by the bitmap size of u8. Even though there are no platfoms with these many policies, but for correctness increase to u32.

2019-04-20thermal/int340x_thermal: fix mode settingMatthew Garrett1-4/+3
[ Upstream commit 396ee4d0cd52c13b3f6421b8d324d65da5e7e409 ] int3400 only pushes the UUID into the firmware when the mode is flipped to "enable". The current code only exposes the mode flag if the firmware supports the PASSIVE_1 UUID, which not all machines do. Remove the restriction.

2015-08-03thermal: consistently use int for temperaturesSascha Hauer1-1/+1
The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

2015-02-28thermal: int340x_thermal: Ignore missing _ART, _TRT tablesSrinivas Pandruvada1-6/+4
It is possible that _ART/_TRT tables are missing or have errors. Ignore those failures, as INT3400 thermal zone is still required for _OSC or mode switch. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

2014-12-09thermal/int3400: export uuidsSrinivas Pandruvada1-2/+78
INT3400 currently supports only one policy, which can't be changed. This change exports all available policies (uuids) to user space and allow this to be changed. It introduces an attribute group uuids in INT3400 platform driver. There are two attributes exposed: - available_uuids - current_uuid User space can set current_uuid via this interface to one of the available uuids. The uuid change is communicated to firmware, only when the current zone mode is changed to "enabled". So the ideal sequence should be - set INT3400 zone mode to "disabled" - change current_uuid - set INT3400 zone mode to "enabled" Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
