mmc: mediatek: Fixed bug where clock frequency could be set wrong

2017-12-20T09:07:23+00:00

[ Upstream commit 40ceda09c8c84694c2ca6b00bcc6dc71e8e62d96 ]

This patch can fix two issues:

Issue 1:
In previous code, div may be overflow when setting clock frequency
as f_min. We can use DIV_ROUND_UP to fix this boundary related
issue.

Issue 2:
In previous code, we can not set the correct clock frequency when
div equals 0xff.

mmc: sdhci-msm: fix issue with power irq

2017-12-09T21:01:48+00:00

[ Upstream commit c7ccee224d2d551f712752c4a16947f6529d6506 ]

SDCC controller reset (SW_RST) during probe may trigger power irq if
previous status of PWRCTL was either BUS_ON or IO_HIGH_V. So before we
enable the power irq interrupt in GIC (by registering the interrupt
handler), we need to ensure that any pending power irq interrupt status
is acknowledged otherwise power irq interrupt handler would be fired
prematurely.

mmc: s3cmci: include linux/interrupt.h for tasklet_struct

2017-11-08T09:08:33+00:00

[ Upstream commit e1c6ec26b853e9062f0b3daaf695c546d0702953 ]

I got this new build error on today's linux-next

drivers/mmc/host/s3cmci.h:69:24: error: field 'pio_tasklet' has incomplete type
  struct tasklet_struct pio_tasklet;
drivers/mmc/host/s3cmci.c: In function 's3cmci_enable_irq':
drivers/mmc/host/s3cmci.c:390:4: error: implicit declaration of function 'enable_irq';did you mean 'enable_imask'? [-Werror=implicit-function-declaration]

While I haven't found out why this happened now and not earlier, the
solution is obvious, we should include the header that defines
the structure.

mmc: dw_mmc: Use device_property_read instead of of_property_read

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

commit 852ff5fea9eb6a9799f1881d6df2cd69a9e6eed5 upstream.

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

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.
