29d904c452 wl1251: rename reg.h to wl1251_reg.h 
Now that wl1271 doesn't use reg.h anymore, it can be renamed to
wl1251_reg.h.

0e71bb084a wl1251: remove wl1251_ops 
Now wl1271 is splitted to separate files, no need to use wl1251_ops anymore.
So remove struct wl1251_chip and wl1251_ops.c.

b5ed9c1b6f wl1251: make irq handling interface specific 
In SDIO, the host driver requests the IRQ and invokes a callback to the
card driver.  This differs from SPI, so the relevant code needs to be
interface-specific.  This patch pushes the irq code down into _spi.c
and _sdio.c, and adds enable/disable callbacks.

This fixes the following warning:

08d9f57251 wl1251: introduce wl1251_if_operations struct 
Introduce an ops struct with read, write, and reset functions to
abstract away the details of the wl1251 bus interface.  Doing this
will allow SDIO to coexist with SPI by supplying its own I/O
routines.

0764de64c8 wl1251: separate bus i/o code into io.c 
In order to eventually support wl1251 spi and sdio interfaces, move
the register and memory transfer functions to a common file.  Also
rename wl1251_spi_mem_{read,write} to indicate its common usage.
We still use spi_read internally until SDIO interface is introduced
so nothing functional should change here.
