NAK.
Err :(, please give me a chance to explain
Test your code against the bindings you send.
I can guarantee to you that I test may code more than twice. The code
used to testing is listed at link [1].
I wrote - test against the bindings. I don't believe that it was tested.
Please paste the output of the testing (dtbs_check).
I *do* run the test against the bindings and the test result say nothing.
I reset my modify today made, then re-run the test again.
I'm telling the truth: the test result say nothing. I paste the log at
below:
make -j$(nproc) ARCH=loongarch

I remember, if there anything wrong, rob's test robot will complain.
let's wait and witness.
This patchset mainly used to illustrate how we made the driver in [1]
usable on our SoC platform.
It's the same
patchset. You basically send something which the same moment is incorrect.
Loongson display controller IP has been integrated in both Loongson
North Bridge chipset(ls7a1000 and ls7a2000) and Loongson SoCs(ls2k1000
and ls2k2000 etc), it even has been included in Loongson BMC(ls2k0500 bmc)
products.
I don't understand how your reply here is relevant to incorrect bindings
or incorrect DTS according to bindings.
Ok, now I know that you refer to the bindings.
I'm a newbie at DT bindings, but i will correct all of the problem you
mentioned.
It takes a few time, thanks for your valuable advice.
Best regards,
Krzysztof
