2023-04-02soc: mediatek: mtk-mmsys: Split out MT8173 mmsys DDP routing tableAngeloGioacchino Del Regno
MT2701, MT2712 and MT8173 were relying on a "default" DDP I/O routing table, describing all of the possible connections between display block components: while this is definitely working it's suboptimal for the actual routing description, as we may be enabling outputs and inputs that are not needed, possibly impacting on actual DDP performance other than slightly prolonging boot times by having to parse a table that is bigger than needed. Seen that all of the other supported SoCs have got their own table and seen that a comment in mtk-mmsys.h explicitly mentions that the wanted way is to have one table per SoC, create a new routing table that is specifically tailored to MT8173 and, while at it, remove mentions to said SoC from the comment in mtk-mmsys.h.

2023-01-25soc: mediatek: mmsys: add mmsys for support 64 reset bitsNancy.Lin
Add mmsys for support 64 reset bits. It is a preparation for MT8195 vdosys1 HW reset. MT8195 vdosys1 has more than 32 reset bits. 1. Add the number of reset bits in mmsys private data 2. move the whole "reset register code section" behind the "get mmsys->data" code section for getting the num_resets in mmsys->data.

2022-11-21Revert "soc: mediatek: add mtk-mmsys support for mt8195 vdosys0"Jason-JH.Lin
This reverts commit b804923b7ccb9c9629703364e927b48cd02a9254. Due to the compatible changing of mt8195 from "mediatek,mt8195-mmsys" to "mediatek,mt8195-vdosys0", we have to revert this patch and send a new patch with the new compatible.

There are different software reset registers for difference MTK SoCs. Therefore, we add a new variable "sw0_rst_offset" to control it.

Among other features the mmsys driver should implement a reset controller to be able to reset different bits from their space.

2021-08-06soc: mediatek: mmsys: Fix missing UFOE component in mt8173 table routingEnric Balletbo i Serra
The UFOE (data compression engine) component needs to be enabled to have the imgtec gpu driver working. If we don't enable it we see a black screen. Looks like when we switched to use and array for setting the routing registers in commit 440147639ac7 ("soc: mediatek: mmsys: Use an array for setting the routing registers") we missed to add this component in the new routing table, it was present before that commit, so fix it by adding this component in the mt8173 routing table.

2021-08-04soc: mmsys: mediatek: add mask to mmsys routesCK Hu
SOUT has many bits and need to be cleared before set new value. Write only could do the clear, but for MOUT, it clears bits that should not be cleared. So use a mask to reset only the needed bits. this fixes HDMI issues on MT7623/BPI-R2 since 5.13 Fixes: 440147639ac7 ("soc: mediatek: mmsys: Use an array for setting the routing registers") Signed-off-by: Frank Wunderlich <frank-w@public-files.de> Signed-off-by: CK Hu <ck.hu@mediatek.com> Reviewed-by: Chun-Kuang Hu <chunkuang.hu@kernel.org> Reviewed-by: Hsin-Yi Wang <hsinyi@chromium.org> Link: https://lore.kernel.org/r/20210729070549.5514-1-linux@fw-web.de Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>
2021-03-30soc: mediatek: mmsys: Use an array for setting the routing registersCK Hu
Actually, setting the registers for routing, use multiple 'if-else' for different routes, but this code would be more and more complicated while we support more and more SoCs. Change that and use a table per SoC so the code will be more portable and clear.
