From 4c21bbb475c16be9ec878e8753d5e8373f9b9d59 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Heiko=20St=C3=BCbner?= Date: Mon, 15 Sep 2014 22:47:00 +0100 Subject: iio: adc: rockchip_saradc: add support for rk3066-tsadc variant Older Rockchip SoCs, at least the rk3066, used a slightly modified saradc for temperature measurements. This so called tsadc does not contain any active parts like temperature interrupts and only supports polling the current temperature. The returned voltage can then be converted by a suitable thermal driver to and actual temperature and used for thermal handling.
