in recent kernel versions there are warnings about incorrect MTU size
like these:
eth0: mtu greater than device maximum
mtk_soc_eth 1b100000.ethernet eth0: error -22 setting MTU to include DSA overhead
Fixes: bfcb813203e6 ("net: dsa: configure the MTU for switch ports")
Fixes: 72579e14a1d3 ("net: dsa: don't fail to probe if we couldn't set the MTU")
Fixes: 7a4c53bee332 ("net: report invalid mtu value via netlink extack")

v3->v4
- fix commit-message (hyphernations,capitalisation) as suggested by Russell
- add Signed-off-by Landen
- dropped wrong signed-off from rene (because previous v1/2 was from him)

This Patch-Series adds missing Patches/Bugfixes to get hdmi working
on BPI-R2
v3->v4:
- fix removed const in "add ddp routing for mt7623"
- change subjects to "drm/mediatek:..."
- add documentation for mt7623-* compatibles
- dropped redundant display_components node (mmsys compatible)
- add reviewd-by collected in v3
v2->v3:
- use own mmsys-routing for mt7623 instead of code getting different
routing from dts
- remove ddp routing bls -> dpi from bpir2/rfb dts
- updated some commit-Messages as suggested by CK Hu
v1->v2:
- using get_possible_crtc API instead of hardcoded
- drop unused dts-nodes
- refine commit-messages as far as i can :)
"config component output by device node port" is needed to fix a WARN_ON()
"fix boot up for 720 and 480 but 1080" fixes flickering,
which may cause also some resolutions not working on some TFT (had some pr>
Frank Wunderlich (2):
dt-bindings: mediatek: add mt7623 display-nodes
drm/mediatek: add ddp routing for mt7623
Jitao Shi (1):
drm/mediatek: dpi/dsi: change the getting possible_crtc way
Ryder Lee (1):
arm: dts: mt7623: add display subsystem related device nodes
Stu Hsieh (1):
drm/mediatek: Add get_possible_crtc API for dpi, dsi
chunhui dai (1):
