[v1] net: fec: Add stop mode support on i.MX8DX/i.MX8QP

[PATCH v1] net: fec: Add stop mode support on i.MX8DX/i.MX8QP

Posted by Francesco Dolcini 1 month, 2 weeks ago

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add additional machines that requires communication to the SC firmware
to set the GPR bit required for stop mode support.

NXP i.MX8DX (fsl,imx8dx) is a low end version of i.MX8QXP (fsl,imx8qxp),
while NXP i.MX8QP (fsl,imx8qp) is a low end version of i.MX8QM
(fsl,imx8qp).

Whoops. I missed the destination branch, this is for net-next, sorry.
