IPQ6018 issues

Fri May 7 03:38:24 PDT 2021

Hi,

I could not previously reply to my inquiry as for whatever reason I
did not receive the message to my email.

I have managed to get the ath11k mostly working on IPQ6018, the issue
was in the APPS PLL and the resets in the GCC driver
were not fully working and some were incorrect.

So, after backporting all of the downstream 5.4 changes to clock
drivers ath11k mostly works, however, if cold-boot calibration is
enabled it will then trigger the remoteproc WDT and crash and hang the
board as well.

However, I have not been able to get the radio working in 80 or 160MHz
mode, only 20MHz.

Trying 80Mhz will simply fail like this log:
