I met the same issue. Maybe you can try modify PUNIT_SEMAPHORE from 0x7 to 0x10E in i2c-designware-baytrail.c. 0x7 is for baytrail and 0x10E is for CHT. This modification can solve the problem of initialization timeout, but in the transmission of data will crash. My hardware use CHT CPU and X-Power PMIC. I want to know if you're going to have the same problem. The kernel isn't compiled by me but from kernel.ubuntu.com/~kernel-ppa/mainline/ My hardware is Wintel Pro CX-W8 TV Box: http://www.sunchip-tech.com/prod_view.aspx?TypeId=50001&Id=86&FId=t3:50001:3 Wintel Pro CX-W8 TV Box uses the Intel Z8300 as CPU. It is the same as my hardware. As far as I know, this problem exists in all the hardware using CHT CPU. On Wintel Pro W8 PRO changing PUNIT_SEMAPHORE to 0x10E makes kernel stuck on loading There really are 2 problems here: 1) On Cherrytrail the punit has the pmic i2c bus access semaphore at a different address (0x10e) 2) iosf_mbi also needs to be bound for things to work. The mainline kernel currently only has iosf_mbi support in pci mode not for acpi mode. So for some people just fixing 1. is enough, but not for everyone. This is currently being discussed in bug 155241, where good progress is being made (patches are attached for both issues), so I'm marking this one as a dup of bug 155241. *** This bug has been marked as a duplicate of bug 155241 *** |
