Subject: [PATCH] ath11k: Add module param to specific caldata file location
|
|
|
|
Add support to specify caldata file load path dynamically
|
|
through module param.
|
|
|
|
ex :
|
|
|
|
insmod ./ath11k.ko ath11k_caldata_bin_path="ath11k"
|
|
|
|
Sample output with dbg print:
|
|
|
|
ath11k_qmi_load_caldata : PATH is ath11k/caldata.bin
|
|
ath11k c000000.wifi: qmi caldata downloaded: type: 2
|
