IPQ807x: No regulatory rules available in the event info

Wed Oct 21 11:51:07 EDT 2020

Hi,

I've just tried QC_IMAGE_VERSION_STRING=WLAN.HK.2.4.0.1.r1-00026-
QCAHKSWPL_SILICONZ-2 on IPQ8074. The board.bin I am loading *has the 
regulatory domain information* included. This worked fine in the past but now 
I get following when I am trying to change the regulatory from US to CA (or 
DE):

    ath11k c000000.wifi1: No regulatory rules available in the event info
    ath11k c000000.wifi1: failed to extract regulatory info from received event

The data which is send down to the device via WMI_SET_INIT_COUNTRY_CMDID is:

    00000000: 0c 00 87 02 02 00 00 00 00 00 00 00 43 41 00 00

Interestingly, this works fine with QC_IMAGE_VERSION_STRING=WLAN.HK.
2.1.0.1-01228-QCAHKSWPL_SILICONZ-1

The skb->data I get in ath11k_pull_reg_chan_list_update_ev is with WLAN.HK.
2.4.0.1.r1-00026-QCAHKSWPL_SILICONZ-2 (fails) is:

    00000000: 38 00 61 02 01 00 00 00 01 00 00 00 43 41 00 00
    00000010: 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

    00000030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 12 00

and with WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1 (works):

    00000000: 38 00 61 02 00 00 00 00 00 00 00 00 43 41 00 00

    00000090: 0c 00 60 02 67 16 cb 16 50 00 1e 06 00 00 00 00

But on bootup (when the US gets "automatically" set), I get with WLAN.HK.
2.4.0.1.r1-00026-QCAHKSWPL_SILICONZ-2 (which usually fails otherwise):

* WLAN.HK.2.4.0.1.r1-00026-QCAHKSWPL_SILICONZ-2: fails

A board.bin is attached which causes the problem. It is just the 
bus=ahb,qmi-chip-id=0,qmi-board-id=255.bin (from IPQ8074/hw2.0/board-2.bin) 
with the REGULATORY_DB_SECTION.regDbFlag set to 1 and the regdb included.

Kind regards,
	Sven
