Subject: ENGR00170520: MX6-Enable WAIT mode by default.
X-Git-Tag: v3.0.35-fsl~1735
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ee13ed6c8a2ba5ac0f4e46fa620018f10cdc571b;p=karo-tx-linux.git

ENGR00170520: MX6-Enable WAIT mode by default.

WAIT mode is enabled by default with this commit.
Adding "enable_wait_mode=off" to the command line will
prevent the system from entering WAIT mode.
