Subject: arm: dts: imx8mp-venice-gw73xx: add TPM device
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=a7d54d3de87d84479a0fd349a2ce7ef8740e9b20;p=u-boot.git

arm: dts: imx8mp-venice-gw73xx: add TPM device

Add the TPM device found on the GW73xx revision F PCB.

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