Didn't quite understand. The patch adds the compatible string for Exynos7870 DECON in documentation.

Although I don't understand why DTS for this piece of hardware would come in different pace, considering you cannot test it without DTS. You have there DTS, so it should be sent. But even without the DTS for DECON, the problem is earlier - lack of basic support for this device. There is nothing for this chip. This means it cannot be tested and is trickier to verify. That's not the usual upstreaming way we expect, especially that you did not provide rationale for such way. Best regards, Krzysztof

Hi, may I ask for reason that you don't submit dts? I am asking because I wonder if there is an issue related to DPP. https://lore.kernel.org/linux-samsung-soc/2e4d3d180f535e57d9cb98e7bac1d14b51ffc5d4.camel@gmail.com/#t Best regards, kwang. > > > > > Best regards, > > Krzysztof

It's not that I don't want, I have nowhere to submit it to yet. As pointed out by Krzysztof, support for exynos7870 doesn't exist in upstream. I'll get back to this after I get that finished. > I am asking because I wonder if there is an issue related to DPP. Exynos7870 doesn't have DPP blocks as far as I could tell.
