| Series | [1/2] arm: dts: mt7623: move more display-related nodes to mt7623n.dtsi | expand |
Hi, as i made a mistake in cover-letter, it is not assigned to the series. to show its content, i send it here as comment (instead of resending the whole series): based on series from David Woodhouse [1] i moved more display-nodes out of mt7623.dtsi to new mt7623n.dtsi and changed last part from my series [2] to add these nodes to this new dtsi the depency of dtsi-dtsi-dts is already done for mt7623a, so i guess it's a good way to use it for mt7623n too. this first set is an RFC if all nodes are in right order and if it is wanted to move them out as i have no technical document about mt7623a/n which describes which parts are available on both or only on one of them added MTK DRM Maintainer CK Hu, Ryder Lee and Sean Wang, maybe they can give me some advice how to proceed further here [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=329209 [2] https://patchwork.kernel.org/patch/11700699/

I would like to see all device in mt7623.dtsi because of its name. If you move some device to platform dtsi, we would trace all platform dtsi to find out how many device in mt7623. One day a new platform enable different devices, you would reorganize all these platform dtsi? Regards, Chun-Kuang.

Or you could have a >better explain for it. As i have documentation for mt7623 and there were no further comments on old series (https://patchwork.kernel.org/patch/10903303/) i guess i cannot fix this. I only know it is needed to get clear image on my 1280x1024 display with this Patch I adressed Ryder and Bibby directly maybe they can help here >I could apply other patches first. I guess i need to fix order in dtsi first...afair any hdmi node creates an serial device moved the others +1. So maybe nodes need to be added after uartx (or at least the one if i found out which). regards Frank

This is mt7623a and mt7623n dtsi for the two different SoCs, and platforms then just include mt7623a.dtsi or mt7623n.dtsi as appropriate for the SoC they are using. If you really want *all* the nodes for both MT7623A and MT7623N chips in a single mt7623.dtsi but disabled, could we still have mt7623a.dtsi and mt7623n.dtsi for the chips, enabling the nodes that are only-for-A or only-for-N, so that each platform doesn't have to do that for itself? Although putting those nodes that exist only in one chip or the other directly into the mt7623[an].dtsi still seems to make more sense to me.

Sorry I does not notice that mt7623a and mt7623n are different SoC. Because they are different SoC, I think the first step is to upstream mt7623a.dtsi and mt7623n.dtsi independently. That means in each dtsi, it include all devices of its SoC. After both dtsi is upsteamed, we could find out what is the common part, then we create a common dtsi these two SoC, for example mt7623a_mt7623n_common.dtsi. (Maybe there is a SoC's name is exactly 'mt7623', so I prefer mt7623.dtsi is reserved for that SoC, and mt7623_common.dtsi is not preferred because I don't know there are how many mt7623 family SoC and mt7623_common.dtsi should be use for all mt7623 family) Regards, Chun-Kuang.

Mt7623a uses mt7623.dtsi as common part. These 2 soc are released 5 years ago...and only these 2 from that family). https://www.mediatek.com/news-events/press-releases/mediatek-launches-the-mt7623-and-mt7683-multi-standard-iot-gateways-with-high-speed-wlan-to-lan-to-drive-the-secure-smart-home So from my current pov the best way (to no more delay my hdmi series) is to move display related stuff in new mt7623n.dtsi and keep mt7623.dtsi as common. So we can avoid touching mt7623a.dtsi for now (can be done later if really needed). regards Frank

I see all three (now I added U7623) MT7623A platforms add the built-in Ethernet switch for themselves, so I'll probably move that to mt7623a.dtsi on top of the series that we're already using. But that can come later.
