Subject: [PATCH v3 00/12] OpenPandora: make wl1251 connected to mmc3 sdio port of OpenPandora work again


* add a revisit note for special wl1251 handling code because it should
  be solved more generic in mmc core - suggested by Ulf Hansson <ulf.hansson@...aro.org>
* remove init_card callback from platform_data/hsmmc-omap.h - suggested by Ulf Hansson <ulf.hansson@...aro.org>
* remove obstructive always-on for vwlan regulator - suggested by Ulf Hansson <ulf.hansson@...aro.org>
* rename DT node - suggested by Rob Herring <robh@...nel.org>
* fix ARM: dts: subject prefix - suggested by Tony Lindgren <tony@...mide.com>
* also remove omap2_hsmmc_info and obc-y line in Makefile - suggested by Tony Lindgren <tony@...mide.com>

PATCH V2 2019-10-19 20:41:47:
* added acked-by for wl1251 patches - Kalle Valo <kvalo@...eaurora.org>
* really removed old pdata-quirks code (not through #if 0)
* splited out a partial revert of
	efdfeb079cc3b ("regulator: fixed: Convert to use GPIO descriptor only")
  because that was introduced after v4.19 and stops the removal of
  the pdata-quirks patch from cleanly applying to v4.9, v4.14, v4.19
  - reported by Sasha Levin <sashal@...nel.org>
* added a new patch to remove old omap hsmmc since pdata quirks
  were last user - suggested by Tony Lindgren <tony@...mide.com>

PATCH V1 2019-10-18 22:25:39:
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
