This is a note to let you know that I've just added the patch titled arm64: dts: marvell: armada-37xx: move firmware node to generic dtsi file to the 5.13-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm64-dts-marvell-armada-37xx-move-firmware-node-to-.patch and it can be found in the queue-5.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 1cdfe25582052f80237822599c17bbe9eeff986a Author: Pali Rohár <pali@xxxxxxxxxx> Date: Thu May 20 13:38:44 2021 +0200 arm64: dts: marvell: armada-37xx: move firmware node to generic dtsi file [ Upstream commit 3a52a48973b355b3aac5add92ef50650ae37c2bd ] Move the turris-mox-rwtm firmware node from Turris MOX' device tree into the generic armada-37xx.dtsi file and use the generic compatible string 'marvell,armada-3700-rwtm-firmware' instead of the current one. Turris MOX DTS file contains also old compatible string for backward compatibility. The Turris MOX rWTM firmware can be used on any Armada 37xx device, giving them access to the rWTM hardware random number generator, which is otherwise unavailable. This change allows Linux to load the turris-mox-rwtm.ko module on these boards. Tested on ESPRESSObin v5 with both default Marvell WTMI firmware and CZ.NIC's firmware. With default WTMI firmware the turris-mox-rwtm fails to probe, while with CZ.NIC's firmware it registers the HW random number generator.
