Subject: arm: dts: imx8m*-venice-gw72xx: add TPM device
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=77dd945b2ca3a19c0327d3666dd35eba772b7abd;p=u-boot.git

arm: dts: imx8m*-venice-gw72xx: add TPM device

The GW71xx baseboard has a TPM that defined in the upstream dt however
we need to ensure the GPIO reset line is de-asserted which we do in boot
firmware with a gpio hog.
