Yes, there is another MTK SoC mt8192 that supports LVTS, I was asked in v10 of the series to remove the unimplemented SoC. It will be added later with the driver that supports it. just let me know if you still want to add mt8192 bindings in the next version without the driver. (LVTS support for mt8192 will be sent in a different series). > > Best regards, > Krzysztof >

The binding should be complete, if that's possible, so if you had mt8192 already there, it could stay. Anyway it's fine then. Best regards, Krzysztof

Anyway it's fine then. OK, I will put back mt8192 dt-bindings. this is the link to the v10 patch "https://patchwork.kernel.org/project/linux-pm/patch/20230112152855.216072-3-bchihi@baylibre.com/", it will be the same in next version (v13) of series. it would be great if you review it in advance, so I could take into account the new changes if needed. is it possible to resend this patch under v13, to simplify the review and avoid breaking the series again? > > Best regards, > Krzysztof > Best regards, Balsam
