The IXP4xx is well supported upstream and can readily be supported with kernel v6.6. To simplify things after the DTS directory was renamed, switch to v6.6 only. Bring in some outstanding patches. Tested on the Gateworks GW2348-4. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Subject: [PATCH] ARM: dts: ixp4xx: Add USRobotics USR8200 device tree
|
|
|
|
This is a USRobotics NAS/Firewall/router that has been supported
|
|
by OpenWrt in the past. It had dedicated users so let's get it
|
|
properly supported.
|
|
|
|
Some debugging and fixing was provided by Howard Harte.
