This patch series adds debug enhancements for mwifiex driver.
Patch series includes patches to dump SDIO function registers/scratch
registers upon FW crash, histogram support, adapter structure dump,
TDLS peer information via debugfs.
Also a patch to control auto deepsleep via module load parameter is added.
Avinash Patil (1):
mwifiex: module parameter for deep sleep configuration
Xinming Hu (7):
mwifiex: report tdls peers in debugfs
mwifiex: add bcn_rcv_cnt and bcn_miss_cnt in getlog debugfs
mwifiex: add rx histogram statistics support
mwifiex: move pm_wakeup_card_complete definition to usb.c
mwifiex: move debug_data dump function to common utililty file
mwifiex: save driver information to file when firmware dump
mwifiex: save sdio register values before firmware dump

This patch adds module parameter for auto deepsleep configuration.
By default, module_param is 0 and auto deep sleep is enabled.
If mwifiex driver is loaded with disable_auto_ds=1, deep sleep
configuration would not be downloaded to FW and FW would not enter
deepsleep upon initializing.

mwifiex_debug_info also need be save to file when firmware dump happens.
Move its dump implementation function to commmon utilility file, thus it
can be reused in firmware dump function.
