Subject: [PATCH 2/7] iio: adc: sun4i-gpadc: introduce temp_data in gpadc_data
Date: Fri,  3 May 2019 03:28:08 -0400	[thread overview]
Message-ID: <20190503072813.2719-3-tiny.windzz@gmail.com> (raw)
In-Reply-To: <20190503072813.2719-1-tiny.windzz@gmail.com>

For some SOCs, the temperature data register start address may be
different, so introduce temp_data in gpadc_data.

Also modify read temperature to support multiple sensor.
