On wl128x based devices, when TX packets are aggregated, each packet
size must be aligned to the SDIO block size, and sent using block mode
transfers.

The block size is set to 256 bytes, which is less than the maximum
possible byte transfer. Thus, if two small packets (< 256 bytes) are
aggregated, the aggregation buffer size would be 512, and will be sent
using byte mode transfers. This can have undesired side effects.

Fix this by setting the MMC_QUIRK_BLKSZ_FOR_BYTE_MODE mmc card quirk.
For 127x chips this has no effect, as the block size is set to 512
bytes.

Boot sequence support FREF clock and TCXO clock.
WL128x has two clocks input - TCXO and FREF.
TCXO is the main clock of the device, while FREF is used to sync
between the GPS and the cellular modem.
Auto-detection checks where TCXO is 32.736MHz or 16.368MHz, in that
case the FREF will be used as the WLAN/BT main clock.

[Use clock enumeration as defined in linux/wl12xx.h; remove
unnecessary else block in wl128x_switch_fref; remove unnecessary
change in main.c; remove some unnecessary debug prints and comments;

Take care of FW & NVS with the auto-detection between wl127x and
wl128x.

[Moved some common code outside if statements and added notes about
NVS structure assumptions; Fixed a bug when checking the nvs size: if
the size was incorrect, the local nvs variable was set to NULL, it
should be wl->nvs instead. -- Luca]

Definitions to support wl128x:
  - New FW file name
  - Chip ID
  - New PLL Configuration Algorithm macros that will be used at wl128x
    boot stage
  - Rename NVS macro name: wl127x and wl128x are using the same NVS
    file name. However, the ini parameters between them are
    different. The driver will validate the correct NVS size in
    wl1271_boot_upload_nvs().

[Cleaned up some of the definitions. -- Luca]

Change some file names and Kconfig settings so that this new module matches
the new way of using wl12xx instead of wl1271.

Also fix SDIO power enabling and disabling to match the latest way of doing
it.

This module enables individually generating RX and TX traffic
over the SDIO bus on which the WL1271 chipset is connected.
This is required to perform RF interference testing.

The module takes 2 module parameters 'rx' and 'tx'.

To generate RX traffic:
	modprobe wl1271_sdio_test rx=1
To generate TX traffic:
	modprobe wl1271_sdio_test tx=1

To generate both RX & TX traffic, set both rx and tx to 1.

You can change the testing configuration at runtime by changing
the rx & tx values at /sys/modules/wl1271_sdio_test/

To stop testing simply unload the module.
