[PATCH v2 1/2] soc: mediatek: introduce a CAPS flag for scp_domain_data
sean.wang at mediatek.com

Mon Apr 23 01:36:21 PDT 2018
From: Sean Wang <sean.wang at mediatek.com>
Instead of adding more and more fields to scp_domain_data which get
checked in the code flow, add a caps field used for an indication the
characteristics for each SCP domain.
At present, type u8 for the caps field is selected which can satisfy the
current situation and doesn't take up extra space against type bool
previously used.
