Subject: [PATCH v5 04/18] thermal: sun8i: get ths sensor number from device compatible
Date: Sat, 10 Aug 2019 05:28:15 +0000 [thread overview]
Message-ID: <20190810052829.6032-5-tiny.windzz@gmail.com> (raw)
In-Reply-To: <20190810052829.6032-1-tiny.windzz@gmail.com>
For different socs, the number of ths sensors is different.
So we need to do some work in order to support more soc.
