Hi, Thanks for the patch but can you please re-send the patch in plain text format? Please refer to this article for more details. https://subspace.kernel.org/etiquette.html On 01/03/2024 01:52, Brock.Zheng wrote: > On TI-AM335x，my FPGA under GPMC local-bus can not work on 6.x kernel. > > GPMC <--> FPGA <--> sub-devices.... > > I found that the platform sub-devices is in wrongly organized > hierarchy.

Are you sure you transliterated/translated your name correctly? Also, please provide Fixes tag (see submitting patches document). Your patch confused my mailer. It looks like HTML, but it seems it is not. Maybe because of Content-Disposition: inline? Why do you have it? Best regards, Krzysztof

I see no html there and Content-Type: text/plain; charset=gb2312 So what do you consider not "plain" in that email? Regards, Andreas

Hi, all
Sorry for the wrong mail Content-Type. My Neomutt is not configured correctly.
Updated info here:
On TI-AM335x，my FPGA under GPMC local-bus can not work on 6.x kernel.
GPMC <--> FPGA <--> sub-devices....
I found that the platform sub-devices are in wrongly organized
hierarchy. The grandchildren are now under the GPMC device directly,
not under it's father(FPGA).

Apply this patch yourself and check the result - is this what you want in commit msg? Best regards, Krzysztof
