From ab43e984049008ecfca7cba7a9d7666da4916d2e Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Thu, 6 Dec 2018 01:42:34 +0000 Subject: [PATCH] ARM: dts: imx6qdl-sabresd: add light sensor support Add isl29023 light sensor support on i2c3 bus, the light sensor's power is controlled by a fixed regulator, since the isl29023 driver and most of other sensors on same board like mag3110 and mma8451 do NOT support regulator operation currently, they are all controlled by this regulator, so this patch also adds the fixed regulator support and make it always on.
