Subject: [PATCH v5 05/18] thermal: sun8i: rework for sun8i_ths_get_temp()
Date: Sat, 10 Aug 2019 05:28:16 +0000
Message-ID: <20190810052829.6032-6-tiny.windzz@gmail.com> (raw)
In-Reply-To: <20190810052829.6032-1-tiny.windzz@gmail.com>

For different socs, the way they get and calculate the
temperature is roughly the same. So get the difference
from device compatible.

Difference point:
  1) temperature calculation formula parameters
  2) ths data register start address
