This patch defines a quirk for tuning work
around for some sdhci host controller. It sets
both SDHCI_CTRL_EXEC_TUNING and SDHCI_CTRL_TUNED_CLK
for tuning.
It is a preparation and will be used by Fujitsu
SDHCI controller f_sdh30 driver.

This patch adds manual resume for some embedded platforms with rootfs
stored in SD card. It references CONFIG_MMC_BLOCK_DEFERRED_RESUME in
kernel 3.10. It lets host controller driver to manually handle resume

There are some UHS-1 SD memory cards sometimes cannot be detected correctly,
e.g., Transcend 600x SDXC 64GB UHS-1 memory card.
During Signal Voltage Switch Procedure, failure to switch is indicated
by the card holding DAT[3:0] low
Hi,
We are adding support for a new Fujitsu sdhci IP.
These patches are against v3.16-rc1 mainline since nothing in
mmc-next at this moment.
These patches are tested on 3.16-rc1 integration tree.
We welcome any comment and advice about how to make any
improvements or better align them with upstr
I have the same question too.
I think we can't get a patch from Linux stable, which isn't accepted
by community.
I used a hard way to get a relative patch which i want by copy source
code from URL and recompile...
Best Regards,
Hsinhsiang

Hi Yuvaraj.
This patch looks like similar Jaehoon's.
Is it resending?
Anyway, I added some comments below.

All Exynos4 SoC based boards have SDHCI controller and mostly
use SD mounted filesystem. Hence it makes sense to default it
to yes on Exynos4 platform. While at it also fix a couple of
typos in the help text.

A standard compliant SDHCI can itself supply VDD at 1.8, 3.0, or 3.3v.
Several vendors ignore this and instead rely upon external regulators
to supply VDD. While the external regulators typically can supply one
of the standard SDHCI voltage levels, there is no real reason for this
to be a hard req
