Subject: [PATCH V5 3/5] arm64: dts: imx8mm: Add system counter node
Date: Wed, 10 Jul 2019 14:30:54 +0800 [thread overview]
Message-ID: <20190710063056.35689-3-Anson.Huang@nxp.com> (raw)
In-Reply-To: <20190710063056.35689-1-Anson.Huang@nxp.com>
From: Anson Huang <Anson.Huang@nxp.com>
Add i.MX8MM system counter node to enable timer-imx-sysctr
broadcast timer driver.
Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
---
Changes since V4:
- update the clock info using fixed clock node;
- correct the reg range;
- update the interrupt number as the system counter driver ONLY uses 1 irq now.
