From mboxrd@z Thu Jan 1 00:00:00 1970 From: zajec5@gmail.com (=?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?=) Date: Fri, 14 Apr 2017 23:42:28 +0200 Subject: [PATCH] ARM: dts: BCM5301X: Add CPU thermal sensor and zone Message-ID: <20170414214228.32521-1-zajec5@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Rafa? Mi?ecki This uses CPU thermal sensor available on every Northstar chipset to monitor temperature. We don't have any cooling or throttling so only a critical trip was added. Signed-off-by: Rafa?
