mmc: mmc: correct the logic for setting HS400ES signal voltage

2017-08-16T20:43:17+00:00

commit 92ddd95919466de5d34f3cb43635da9a7f9ab814 upstream.

Change the default err value to -EINVAL, make sure the card only
has type EXT_CSD_CARD_TYPE_HS400_1_8V also do the signal voltage
setting when select hs400es mode.

Fixes: commit 1720d3545b77 ("mmc: core: switch to 1V8 or 1V2 for hs400es mode")

mmc: core: Use device_property_read instead of of_property_read

2017-08-11T15:49:31+00:00

commit 73a47a9bb3e2c4a9c553c72456e63ab991b1a4d9 upstream.

Using the device_property interfaces allows mmc drivers to work
on platforms which run on either device tree or ACPI.

mmc: core: Fix access to HS400-ES devices

2017-08-11T15:49:29+00:00

commit 773dc118756b1f38766063e90e582016be868f09 upstream.

HS400-ES devices fail to initialize with the following error messages.

mmc1: power class selection to bus width 8 ddr 0 failed
mmc1: error -110 whilst initialising MMC card

This was seen on Samsung Chromebook Plus. Code analysis points to
commit 3d4ef329757c ("mmc: core: fix multi-bit bus width without
high-speed mode"), which attempts to set the bus width for all but
HS200 devices unconditionally. However, for HS400-ES, the bus width
is already selected.

mmc: sdhci-of-at91: force card detect value for non removable devices

2017-08-11T15:49:28+00:00

commit 7a1e3f143176e8ebdb2f5a9b3b47abc18b879d90 upstream.

When the device is non removable, the card detect signal is often used
for another purpose i.e. muxed to another SoC peripheral or used as a
GPIO. It could lead to wrong behaviors depending the default value of
this signal if not muxed to the SDHCI controller.

mmc: sdhci-iproc: suppress spurious interrupt with Multiblock read

2017-06-07T10:07:47+00:00

commit f5f968f2371ccdebb8a365487649673c9af68d09 upstream.

The stingray SDHCI hardware supports ACMD12 and automatically
issues after multi block transfer completed.

If ACMD12 in SDHCI is disabled, spurious tx done interrupts are seen
on multi block read command with below error message:

Got data interrupt 0x00000002 even though no data
operation was in progress.

This patch uses SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 to enable
ACM12 support in SDHCI hardware and suppress spurious interrupt.

Revert "mmc: sdhci-msm: Enable few quirks"

2017-05-03T15:36:34+00:00

This reverts commit d84be51d1c1d3fa148a3abdeeb1455690df59e63 which is
commit a0e3142869d29688de6f77be31aa7a401a4a88f1 upstream.

It causes problems and would need other patches backported to resolve
it, and it shouldn't have been applied to 4.9-stable.

mmc: sdhci-esdhc-imx: increase the pad I/O drive strength for DDR50 card

2017-04-27T07:10:38+00:00

commit 9f327845358d3dd0d8a5a7a5436b0aa5c432e757 upstream.

Currently for DDR50 card, it need tuning in default. We meet tuning fail
issue for DDR50 card and some data CRC error when DDR50 sd card works.

This is because the default pad I/O drive strength can't make sure DDR50
card work stable. So increase the pad I/O drive strength for DDR50 card,
and use pins_100mhz.

This fixes DDR50 card support for IMX since DDR50 tuning was enabled from
commit 9faac7b95ea4 ("mmc: sdhci: enable tuning for DDR50")

mmc: sdhci-of-esdhc: remove default broken-cd for ARM

2017-04-12T10:41:22+00:00

[ Upstream commit e9acc77dd046b22c7ebf70e35f68968978445f8b ]

Initially all QorIQ platforms were PowerPC architecture and they didn't
support card detection except several platforms. The driver added the
quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION as default and this made broken-cd
property in dts node didn't work. Now QorIQ platform turns to ARM
architecture and most of them could support card detection. However it's
a large number of dts trees that need to be fixed with broken-cd if we
remove the default SDHCI_QUIRK_BROKEN_CARD_DETECTION in driver. And the
users don't want to see this. So this patch is to remove this default
quirk just for ARM and keep it for PowerPC.(Note, QorIQ PowerPC platform
only has big-endian eSDHC while QorIQ ARM platform has big-endian or
little-endian eSDHC) This makes broken-cd property work again for ARM.
