052a625a85 wl12xx: add support for fixed address in wl12xx_spi_read 
In the wl1271 implementation, we need to read memory from the register
partition using fixed addresses.  This change adds the possibility to request
fixed address when calling wl12xx_spi_read() or wl12xx_spi_reg_read().

a336e26664 wl12xx: add wl12xx_spi_reg_read() and wl12xx_spi_reg_write() functions 
In some cases we need to read more than 32 bits from the register area.
These functions were added to support that, like the existing
wl12xx_spi_mem_read() and wl12xx_spi_mem_write() already do for large blocks
in the memory area.

2f01a1f588 wl12xx: add driver 
wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:
