This is caused by the dtsi for sun4i / sun5i / sun7i based boards now listing pll3, without pll3 being added to the clocks list for the simplefb nodes. For sun5i-r8 this does not happen because it lists the de_be and tcon_ch#_clk in the framebuffer node's clocks which will in turn keep ppl3 (and pll5) alive. With this commit: https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git/commit/?h=sunxi/for-next&id=eadc0660c2bca3a2a6d2c15fe04bc2aaa2709cef This is also fixed for A13 based devices, but it still is a problem for A10s, hence this patch, which sits on top of the commit I just linked too. Note that we've the same problem in 4.7-rc1 for A10 / A20, this is fixed by these 2 commits: https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git/commit/?id=5a7f2310cc847a73852e70bc720a61ca9bf986a6 https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git/commit/?id=c79255ca4d7b67cce4eac4dd532e097ce49f3679 This also means that we must send all 3 linked commits + the patch I'm sending now to 4.7 as fixes, to avoid regressing in 4.7.
