Subject: [PATCH RFC 2/9] OPP: Export a number of helpers to prevent code duplication
Date: Thu, 28 Mar 2019 20:58:15 +0530
Message-ID: <20190328152822.532-3-sibis@codeaurora.org> (raw)
In-Reply-To: <20190328152822.532-1-sibis@codeaurora.org>

Export 'dev_pm_opp_find_opp_of_np' and 'of_parse_required_nodes'
as it will be used by passive governor to parse and auto-populate
mapping specified using the required-opps property.
