[PATCH 1/2] reset: Add DesignWare IP support to simple reset

From: Gustavo Pimentel
Date: Mon May 13 2019 - 11:43:19 EST


The reset-simple driver can be now used on DesignWare IPs by
default by selecting the following compatible strings:
- snps,dw-high-reset for active high resets inputs
- snps,dw-low-reset for active low resets inputs
