a04184ce77 mmc: sdhci-of-at91: fix memleak on clk_get failure 
sdhci_alloc_host() does its work not using managed infrastructure, so
needs explicit free on error path. Add it where needed.

There is an official update for eSDHC tuning erratum A-008171.
This patch is to implement the changes,
- Affect all revisions of SoC.
- Changes for tuning window checking.
- Hardware hits a new condition that tuning succeeds although
  the eSDHC might not have tuned properly for type2 SoCs
  (soc_tuning_erratum_type2[] array in driver). So check
  tuning window after tuning succeeds.

2253ed4b36 mmc: mmci: Support any block sizes for ux500v2 and qcom variant 
For the ux500v2 variant of the PL18x block, any block sizes
are supported. This is necessary to support some SDIO
transfers. This also affects the QCOM MMCI variant and the
ST micro variant.

For Ux500 an additional quirk only allowing DMA on blocks
that are a power of two is needed. This might be a bug in
the DMA engine (DMA40) or the MMCI or in the interconnect,
but the most likely is the MMCI, as transfers of these
sizes work fine for other devices using the same DMA
engine. DMA works fine also with SDIO as long as the
blocksize is a power of 2.

This patch has proven necessary for enabling SDIO for WLAN on
PostmarketOS-based Ux500 platforms.

What we managed to test in practice is Broadcom WiFi over
SDIO on the Ux500 based Samsung GT-I8190 and GT-S7710.
This WiFi chip, BCM4334 works fine after the patch.

Before this patch:

brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4334-sdio
	  for chip BCM4334/3
mmci-pl18x 80118000.sdi1_per2: unsupported block size (60 bytes)
brcmfmac: brcmf_sdiod_ramrw: membytes transfer failed
brcmfmac: brcmf_sdio_download_code_file: error -22 on writing
	  434236 membytes at 0x00000000
brcmfmac: brcmf_sdio_download_firmware: dongle image file download
	  failed

After this patch:

brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4334/3 wl0:
	  Nov 21 2012 00:21:28 version 6.10.58.813 (B2) FWID 01-0

Bringing up networks, discovering networks with "iw dev wlan0 scan"
and connecting works fine from this point.

This patch is inspired by Ulf Hansson's patch
http://www.spinics.net/lists/linux-mmc/msg12160.html

As the DMA engines on these platforms may now get block sizes
they were not used to before, make sure to also respect if
the DMA engine says "no" to a transfer.

Make a drive-by fix for datactrl_blocksz, misspelled.

Command queuing has been reported broken on some systems based on Intel
GLK. A separate patch disables command queuing in some cases.

This patch adds a quirk for broken command queuing, which enables users
with problems to disable command queuing using sdhci module parameters for
quirks.

bedf9fc01f mmc: sdhci: Workaround broken command queuing on Intel GLK 
Command queuing has been reported broken on some Lenovo systems based on
Intel GLK. This is likely a BIOS issue, so disable command queuing for
Intel GLK if the BIOS vendor string is "LENOVO".

fe0acab448 mmc: sdhci-of-esdhc: fix P2020 errata handling 
Two previous patches introduced below quirks for P2020 platforms.
- SDHCI_QUIRK_RESET_AFTER_REQUEST
- SDHCI_QUIRK_BROKEN_TIMEOUT_VAL

The patches made a mistake to add them in quirks2 of sdhci_host
structure, while they were defined for quirks.
	host->quirks2 |= SDHCI_QUIRK_RESET_AFTER_REQUEST;
	host->quirks2 |= SDHCI_QUIRK_BROKEN_TIMEOUT_VAL;

This patch is to fix them.
	host->quirks |= SDHCI_QUIRK_RESET_AFTER_REQUEST;
	host->quirks |= SDHCI_QUIRK_BROKEN_TIMEOUT_VAL;

Fixes: 05cb6b2a66 ("mmc: sdhci-of-esdhc: add erratum eSDHC-A001 and A-008358 support")
Fixes: a46e427125 ("mmc: sdhci-of-esdhc: add erratum eSDHC5 support")

ee157abebc mmc: mmci: add threaded irq to abort DPSM of non-functional state 
The stm32_sdmmc variant has build-in support for datatimeout for R1B
requests. If a corresponding IRQ is raised, this triggers the DPSM to stay
busy and remains in a non-functional state. Only a reset can bring it back
to a functional state.

Because a reset must be issued from non-atomic context, let's defer this to
be managed from a threaded IRQ handler. Besides the reset, the threaded
handler also calls mmc_request_done(), to finally complete the request.

0f7c815d83 mmc: core: Rework cd-gpio handling 
There are a few places around the code that invert inverted and possibly
inverted CD line. That's really confusing. Squash them all into one place
in mmc_gpiod_request_cd(). MMC_CAP2_CD_ACTIVE_HIGH is used analogously to
WP line: in GPIO mode it is used only at probe time to switch polarity, for
native mode it is left as is.

9073d10b09 mmc: core: Rework wp-gpio handling 
Use MMC_CAP2_RO_ACTIVE_HIGH flag as indicator if GPIO line is to be
inverted compared to DT/platform-specified polarity. The flag is not used
after init in GPIO mode anyway. No functional changes intended.
