Hi, if you won't be able to reduce SPL size, you can cherry pick some commits from this branch: https://github.com/megous/linux/commits/ths-4.14 to get working SY8106A suppport on PC2. regards, o. > cheers! > > > > -- > > You received this message because you are subscribed to the Google Groups > "linux-sunxi" group. > > To unsubscribe from this group and stop receiving emails from it, send an > email to linux-sunxi+unsubscr...@googlegroups.com. > > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
