Subject: [PATCH] brcmfmac: handle FWHALT mailbox indication
|
|
|
|
The firmware uses a mailbox to communicate to the host what is going
|
|
on. In the driver we validate the bit received. Various people seen
|
|
the following message:
|
|
|
|
brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012
|
|
|
|
Bit 4 is cause of this message, but this actually indicates the firmware
|
|
has halted. Handle this bit by giving a more meaningful error message.
