[Letux-kernel] [PATCH 0/9] OpenPandora: make wl1251 connected to mmc3 sdio port of OpenPandora work again

Here we have a set of scattered patches to make the OpenPandora WiFi work again.

v4.7 did break the pdata-quirks which made the mmc3 interface
fail completely, because some code now assumes device tree
based instantiation.

Fixes: 81eef6ca9201 ("mmc: omap_hsmmc: Use dma_request_chan() for requesting DMA channel")

v4.11 did break the sdio qirks for wl1251 which made the driver no longer
load, although the device was found as an sdio client.

Fixes: 884f38607897 ("mmc: core: move some sdio IDs out of quirks file")

To solve these issues:
* we convert mmc3 and wl1251 initialization from pdata-quirks
  to device tree
* we make the wl1251 driver read properties from device tree
* we fix the mmc core vendor ids and quirks
* we fix the wl1251 (and wl1271) driver to use only vendor ids
  from header file instead of (potentially conflicting) local
  definitions
