Subject: [PATCH 5/5] arm: dts: imx8mp-venice-gw71xx: add TPM device
Date: Mon,  5 Feb 2024 11:08:58 -0800	[thread overview]
Message-ID: <20240205190858.3076363-6-tharvey@gateworks.com> (raw)
In-Reply-To: <20240205190858.3076363-1-tharvey@gateworks.com>

Add the TPM device found on the GW71xx revision E PCB.

This hangs off of SPI2, uses gpio1_10 as a CS and gpio1_11 as RST#.

Signed-off-by: Tim Harvey <tharvey@gateworks.com>
