Subject: arm: dts: imx8mp-venice-gw72xx: add TPM device
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=c0689191f1205289ec5f422a9e707fa466907f69;p=u-boot.git

arm: dts: imx8mp-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#.
