From a4887813c3a9481ab87c8a71ab1de50b975cc823 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Mon, 25 Dec 2017 14:37:09 +0800 Subject: regmap: Add one flag to indicate if a hwlock should be used Since the hwlock id 0 is valid for hardware spinlock core, but now id 0 is treated as one invalid value for regmap. Thus we should add one extra flag for regmap config to indicate if a hardware spinlock should be used, then id 0 can be valid for regmap to request.
