Subject: [PATCH 13/13] twl4030_charger: assume a 'charger' can supply maximum current.
Date: Thu, 30 Jul 2015 10:11:25 +1000 [thread overview]
Message-ID: <20150730001124.4012.1604.stgit@noble> (raw)
In-Reply-To: <20150730001113.4012.18086.stgit@noble>
If it cannot, we will stop pulling more current when voltage drops.
