Teemu Paasikivi 760d969f9e wl1271: Removed wl1271_spi.h and made some functions static
Removed wl1271_spi.h header as there's no more need to access functions
declared there outside of wl1271_spi.c. Also made those SPI access
functions static.

Juuso Oikarinen d8c42c0c28 wl1271: Fix PSM entry
Currently the PSM entry function assumes successful operation, and enables
ELP, BET and beacon filtering right away. This is bad, because the PSM
entry may fail due to environmental issues, which will cause the ELP, BET and
beacon filtering to be illegally enabled (because FW remains in active state.)

Fix this by enabling ELP, BET and beacon filtering only after successful entry,
and by ensuring the firmware is in active mode after the failure.

Juuso Oikarinen 71449f8d70 wl1271: Change booleans in struct wl1271 into a flags bitmask
For cleaner implementation, change the bunch of booleans in the struct wl1271
structure into a flags bitmask.

Juuso Oikarinen 11f70f9715 wl1271: Implement beacon early termination support
Add support to enable beacon early termination in the firmware. Early
Beacon termination is a feature which allows the radio to be turned off
after TIM IE to save power.

Juuso Oikarinen 7462141787 wl1271: Remove outdated SPI functions
With the change to the new firmware, there was a change to firmware memory
partitioning. Along with that change, the translation of all partitions was
unified, and separate functions for reg and mem access became unnecessary.

Cleanup the unnecessary functions.

Juuso Oikarinen 37b70a8185 wl1271: Implement delayed entry into ELP
Implement delayed entry into ELP. This will promote the following:
 - Less redundant sleep/wake cycles (better perf)
 - Avoids known firmware issues with going to ELP too fast after an
   operation

Luciano Coelho f5fc0f86b0 wl1271: add wl1271 driver files
This driver supports the wl1271 chipset from Texas Instruments based on the
WiLink(tm) 6.0 mobile platform.  Support for wl1273 should be relatively easy
to add.  This chipset is designed for embedded devices, with good powersaving
capabilities.  The wl1271 chipset is the successor of wl1251 and supports the
802.11b/g/n standards, but currently this driver supports only b/g.

More information about this chipset can be found here:
