Subject: arm: dts: imx8mm-venice-gw72xx: add TPM device
X-Git-Url: http://git.dujemihanovic.xyz/html/static/gitweb.css?a=commitdiff_plain;h=b1c40d069206dac25a2124b613229eab54594abb;p=u-boot.git

arm: dts: imx8mm-venice-gw72xx: add TPM device

Add the TPM device found on the GW72xx revision F PCB.

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