Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal
Pull thermal SoC management fixes from Eduardo Valentin: - fixes to TI SoC driver, Broadcom, qoriq - small sparse warning fix on thermal core * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal: thermal: broadcom: ns-thermal: default on iProc SoCs ti-soc-thermal: Fix a typo in a comment line ti-soc-thermal: Delete error messages for failed memory allocations in ti_bandgap_build() ti-soc-thermal: Use devm_kcalloc() in ti_bandgap_build() thermal: core: make thermal_emergency_poweroff static thermal: qoriq: remove useless call for of_thermal_get_trip_points()

- Northstar is a family of SoCs that includes e.g. BCM4708, BCM47081,
- BCM4709 and BCM47094. It contains DMU (Device Management Unit) block
- with a thermal sensor that allows checking CPU temperature. This
- driver provides support for it.
