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

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

[H. Nikolaus Schaller]

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

[H. Nikolaus Schaller]

The standard method for sdio devices connected to
an sdio interface is to define them as a child node

[PATCH 3/9] DTS: ARM: pandora-common: define wl1251 as child node of mmc3

[H. Nikolaus Schaller]

Since v4.7 the dma initialization requires that there is a
device tree property for "rx" and "tx" channels which is
not provided by the pdata-quirks initialization.

By conversion of the mmc3 setup to device tree this will
finally allows to remove the OpenPandora wlan specific omap3
data-quirks.

[PATCH 3/9] DTS: ARM: pandora-common: define wl1251 as child node of mmc3

[H. Nikolaus Schaller]

Since v4.7 the dma initialization requires that there is a
device tree property for "rx" and "tx" channels which is
not provided by the pdata-quirks initialization.

By conversion of the mmc3 setup to device tree this will
finally allows to remove the OpenPandora wlan specific omap3
data-quirks.

[PATCH 4/9] mmc: host: omap_hsmmc: add code for special init of wl1251 to get rid of pandora_wl1251_init_card

[H. Nikolaus Schaller]

Pandora_wl1251_init_card was used to do special pdata based
setup of the sdio mmc interface. This does no longer work with
v4.7 and later. A fix requires a device tree based mmc3 setup.

Therefore we move the special setup to omap_hsmmc.c instead
of calling some pdata supplied init_card function.

The new code checks for a DT child node compatible to wl1251
so it will not affect other MMC3 use cases.

[PATCH 6/9] mmc: sdio: fix wl1251 vendor id

[H. Nikolaus Schaller]

v4.11-rc1 did introduce a patch series that rearranged the
sdio quirks into a header file. Unfortunately this did forget
to handle SDIO_VENDOR_ID_TI differently between wl1251 and
wl1271 with the result that although the wl1251 was found on
the sdio bus, the firmware did not load any more and there was
no interface registration.

This patch defines separate constants to be used by sdio quirks
and drivers.

[PATCH 7/9] mmc: core: fix wl1251 sdio quirks

[H. Nikolaus Schaller]

wl1251 and wl1271 have different vendor id and device id.
So we need to handle both with sdio quirks.

I didn't get patches 3-7 so I don't know what they have, but what's the
plan how these should be applied? Normally wl1251 patches go via
wireless-drivers-next but are you planning something else?

oh sorry. I don't know why.

Here they are all: https://patchwork.kernel.org/cover/11199599/

Well, I have no plan for that except that all should end up fixed in mainline
and stable.

The issue is that multiple subsystems are involved (net/wireless, mmc and arm/omap)
and all patches should be ideally be applied in combination.

BR and thanks,

Ok, I then assume someone else is going to handle these, wl1251 rarely
has any changes so the chance of conflicts is small anyway, and I'll
drop the wl1251 patches from my patchwork.
