Subject: [PATCH v5 1/5] ARM: dts: NSP: Add common bindings for MX64/MX65
Date: Fri,  6 Aug 2021 21:44:32 +0100	[thread overview]
Message-ID: <20210806204446.2981299-2-mnhagan88@gmail.com> (raw)
In-Reply-To: <20210806204446.2981299-1-mnhagan88@gmail.com>

These bindings are required for all Meraki MX64/MX65 devices. These
common bindings include memory (2GB), PWM LEDs, AMAC, I2C (AT24), NAND
partitions, EHCI, OHCI and pinctrl.
