[PATCH v2 2/6] mmc: core: allow to match the device tree to apply quirks

[H. Nikolaus Schaller]

From: Jérôme Pouiller <jerome.pouiller@silabs.com>

MMC subsystem provides a way to apply quirks when a device match some
properties (VID, PID, etc...) Unfortunately, some SDIO devices do not
comply with the SDIO specification and does not provide reliable VID/PID
(eg. Silabs WF200).

So, the drivers for these devices rely on device tree to identify the
device.

This patch allows the MMC to also rely on the device tree to apply a
quirk.

[PATCH v2 3/6] mmc: core: provide macro and table to match the device tree to apply quirks

[H. Nikolaus Schaller]

This (initially empty) table allows to match quirks early based
on .compatible of the child node of some mmc/sdio interface.

This allows to add quirks based on device tree instead of having
card specific code in the host ops.

A new macro SDIO_FIXUP_COMPATIBLE makes the definition readable.

And we call mmc_fixup_device(sdio_card_init_methods) just after
where host->ops->init_card() can be optionally called.

[PATCH v2 4/6] mmc: core: Fixup storing of OCR for MMC_QUIRK_NONSTD_SDIO

[H. Nikolaus Schaller]

From: Ulf Hansson <ulf.hansson@linaro.org>

The mmc core takes a specific path to support initializing of a
non-standard SDIO card. This is triggered by looking for the card-quirk,
MMC_QUIRK_NONSTD_SDIO.

In mmc_sdio_init_card() this gets rather messy, as it causes the code to
bail out earlier, compared to the usual path. This leads to that the OCR
doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has
been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by
assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.

To make the behaviour consistent, let's instead rely on the core to save
the OCR in card->ocr during initialization.

[PATCH v2 5/6] mmc: core: transplant ti,wl1251 quirks from to be retired omap_hsmmc

[H. Nikolaus Schaller]

The TiWi WL1251 WiFi chip needs special setup of the sdio
interface before it can be probed.

So far, this is done in omap_hsmmc_init_card() in omap_hsmmc.c
which makes it useable only if connected to omap devices
which use the omap_hsmmc. The OpenPandora is the most promient
example.

There are plans to switch to a newer sdhci-omap driver and
retire omap_hsmmc. Hence this quirk must be reworked or moved
somewhere else. Ideally to some location that is not dependent
on the specific SoC mmc host driver.

This is achieved by the new mmc_fixup_device() option introduced
by ("mmc: allow to match the device tree to apply quirks") to match
through device tree compatible string.

This quirk will be called early right after where host->ops->init_card()
and thus omap_hsmmc_init_card() was previously called.

Note that we do not need to transplant

	card->ocr = 0x80;

because we rely on ("mmc: core: Fixup storing of OCR for MMC_QUIRK_NONSTD_SDIO").

Replaces: commit f6498b922e57 ("mmc: host: omap_hsmmc: add code for special init of wl1251 to get rid of pandora_wl1251_init_card")
Requires: commit ("mmc: core: transplant ti,wl1251 quirks from to be retired omap_hsmmc")

After moving the wl1251 quirks from omap_hsmmc_init_card() to wl1251_quirk()
and sdio_card_init_methods[] we can remove omap_hsmmc_init_card() completely.

This also removes the specialization on the combination of omap_hsmmc and wl1251.
