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

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