From: Anson Huang Date: Sat, 22 Feb 2020 00:08:48 +0000 (+0800) Subject: dt-bindings: fsl: scu: add thermal binding X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7dc6ffbd79c22b3a8433290a692c57e1917575a4;p=linux.git dt-bindings: fsl: scu: add thermal binding NXP i.MX8QXP is an ARMv8 SoC with a Cortex-M4 core inside as system controller, the system controller is in charge of system power, clock and thermal sensors etc. management, Linux kernel has to communicate with system controller via MU (message unit) IPC to get temperature from thermal sensors, this patch adds binding doc for i.MX system controller thermal driver.
