Re: [linux-sunxi] [PATCH v3 06/16] drm/sun4i: Release exclusive clock lock when disabling TCON

Hi, I've debugged this further and it seems that the code has incorrect assumptions. See docs for mode_set_nofb. https://elixir.bootlin.com/linux/v4.16-rc4/source/include/drm/drm_modeset_helper_vtables.h#L209 I've added traces to a few functions that call clk_.*exclusive.*() functions, and I

Re: [linux-sunxi] Re: DRM fb issue - Kernel 4.15.7

Ok, will test Ondřej and your branch. This can take some time, I think this weekend I can build and test both. But this raised some questions: a) How is this going to help you guys fix the stable 4.15.y ? b) I applied the significant changes on DRM and sun4i (that i think would fix) on my 4.15
