[PATCH v2 21/34] ARM: tegra: apalis_t30: add i2c-thermtrip

From: Marcel Ziswiler
Date: Fri Aug 31 2018 - 12:40:50 EST


From: Marcel Ziswiler <marcel.ziswiler@xxxxxxxxxxx>

Add i2c-thermtrip which would set the DEV_OFF bit in the DCDC control
register of the TPS65911 PMIC.

Signed-off-by: Marcel Ziswiler <marcel.ziswiler@xxxxxxxxxxx>

Changes in v2:
- When running some more tests I realized that the reg-addr should
really be 0x3f. Fix this.
