Adding support for TI bandgap temperature sensor.
Also add dt support for bandgap sensor in spl.
v4:
1. Added configs enabled by default in dra7xx and am57xx SOCs
2. Split config enabling in a separate commit
v3:
Missed adding Reviewed-by in v2.
Faiz Abbas (3):
thermal: ti-bandgap: Add support for temperature sensor
ARM: dts: OMAP5+: Add support for bandgap sensor in SPL
arm: Kconfig: Add thermal config options for dra7xx and am57xx
