Subject: [PATCH] brcmfmac: add dedicated debug level for firmware
|
||
|
console logging
|
||
|
|
||
|
Both PCIe and SDIO devices have the possibility to log the firmware
|
||
|
console output in kernel log. For PCIe it is logged when PCIE debug
|
||
|
level is enabled. For SDIO it is logged when user specifies a non-zero
|
||
|
console interval through debugfs. This patch tries to make it a
|
||
|
bit more consistent. The firmware console output is only logged when
|
||
|
FWCON debug level is enabled.
