This patch extends the of-thermal.c to provide information about number of available trip points.
Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> --- Changes for v3: - Exporting of_thermal_get_ntrips symbol as a GPL - Fix build error when CONFIG_THERMAL_OF is disabled
Changes for v2: - Provide detailed (doxygen like) description of the of_thermal_get_ntrips() method - Check for data pointer not being NULL --- drivers/thermal/of-thermal.c | 21 +++++++++++++++++++++ drivers/thermal/thermal_core.h | 5 +++++ 2 files changed, 26 insertions(+)
