eee20f8132 STiH410: Add STi SDHCI driver
Add SDHCI host controller found on STMicroelectronics SoCs

On some ST SoCs, i.e. STiH407/STiH410, the MMC devices can live
inside a dedicated flashSS sub-system that provides an extend subset
of registers that can be used to configure the Arasan MMC/SD Host
Controller.

This means, that the SDHCI Arasan Controller can be configured to be
eMMC4.5 or 4.3 spec compliant.

W/o these settings the SDHCI will configure and use the MMC/SD
controller with limited features e.g. PIO mode, no DMA, no HS etc.

On the OMAP36xx/37xx the CONTROL_WKUP_CTRL register has
a field (bit 6) named GPIO_IO_PWRDNZ.  If 0, the IO buffers which
are related to GPIO_126, 127 and 129 are disabled. Some boards may
need this for MMC. After the PBIAS is configured, this bit should

02ad33aa3a mmc: mmc-uclass: use the fixed devnum with alias node
If there are alias nodes as "mmc", use the devnum as alias index
number.
This patch is for fixing a problem of Exynos4 series.
Problem is the below thing.

Current legacy mode:
EXYNOS DWMMC: 0, SAMSUNG SDHCI: 1

After using DM:
SAMSUNG SDHCI: 0, EXYNOS DWMMC: 1

Dev index is swapped.
Then u-boot can't find the kernel image..because it is already set to 0 as mmcdev.
If change from legacy to DM, also needs to touch all exynos4 config file.
For using simply, just supporting the fixed devnum with alias node is better than it.

Usage:
alaise {
	....
	mmc0 = &sdhci2; /* eMMC */
	mmc1 = &sdhci1; /* SD */
	...
}

54925327fa mmc: move CONFIG_GENERIC_MMC to Kconfig
Now, CONFIG_GENERIC_MMC seems equivalent to CONFIG_MMC.

Let's create an entry for "config GENERIC_MMC" with "default MMC",
then convert all macro defines in headers to Kconfig.  Almost all
of the defines will go away.

I see only two exceptions:
  configs/blanche_defconfig
  configs/sandbox_noblk_defconfig

They define CONFIG_GENERIC_MMC, but not CONFIG_MMC.  Something
might be wrong with these two boards, so should be checked later.

Anyway, this is the output of the moveconfig tool.

This commit was created as follows:

[1] create a config entry in drivers/mmc/Kconfig

[2] tools/moveconfig.py -r HEAD GENERIC_MMC

This patch completely clears the SDHCI_CLOCK_CONTROL register before the

SDHCI_CLOCK_CARD_EN and SDHCI_CLOCK_INT_EN. Without this change, some

error message on the Xenon SDHCI controller used on the Marvell Armada
3700 and 7k/8k ARM64 SoCs.

The Linux SDHCI core driver also writes 0 to this register before
the new value is configured. So this patch simplifies the driver a bit
and brings the U-Boot driver more in-line with the Linux one.

6d0e34bf4e mmc: sdhci: Distinguish between base clock and maximum peripheral frequency
The sdhci controller assumes that the base clock frequency is fully supported by
the peripheral and doesn't support hardware limitations. The Linux kernel
distinguishes between base clock (max_clk) of the host controller and maximum
frequency (f_max) of the card interface. Use the same differentiation and allow
the platform to constrain the peripheral interface.

bf9c4d1464 mmc: sdhci: fix NULL pointer access when host->ops is not set
Until recently, sdhci_ops was used only for overriding IO accessors.
(so, host->ops was not set by any drivers except bcm2835_sdhci.c)

Now, we have more optional callbacks, get_cd, set_control_reg, and
set_clock.  However, the code

    if (host->ops->get_cd)
            host->ops->get_cd(host);

... expects host->ops is set for all drivers.

Commit 5e96217f04 ("mmc: pic32_sdhci: move the code to
pic32_sdhci.c") and commit 62226b6863 ("mmc: sdhci: move the
callback function into sdhci_ops") added sdhci_ops for pic32_sdhci.c
and s5p_sdhci.c, but the other drivers still do not (need not) set
host->ops because all callbacks in sdhci_ops are optional.

host->ops must be checked to avoid the system crash caused by NULL
pointer access.

9c720c815b mmc: uniphier-sd: fix Kconfig dependency
Some MMC drivers describe operations with the DM_MMC_OPS form, but
there are still several drivers with older implementation.  We can
not compile drivers from different groups at the same time because
the core framework is shared with #ifdef CONFIG_DM_MMC_OPS.

Every driver should have "depends on DM_MMC_OPS" (or !DM_MMC_OPS)
explicitly to express which framework it is based on.  This will
avoid enabling drivers with incompatible interface at the same time.
It is incorrect to make a driver "select DM_MMC_OPS".

While we are here, add "depends on OF_CONTROL" as well because this
driver can be configured only by Device Tree.

So the buswidth mode selection leaves a matter in each SoC drivers.

On the contrary to this, hardware supports 8bit mode, but host doesn't
support it. then controller has to disable the MMC_MODE_8BIT.
(Host can check whether 8bit mode is supported or not, since V3.0)

3d3a74cc8c mmc: move MMC_SDHCI_IO_ACCESSORS to Kconfig
This is a user-unconfigurable option that is selected by the
drivers that need to overwrite SDHCI IO memory accessors.
(BCM2835 SDHCI seems the only driver that needs to do so.)

45a68fe267 mmc: move some SDHCI related options to Kconfig
While I moved the options, I also renamed them so that they are all
prefixed with MMC_SDHCI_.

This commit was created in the following steps.

[1] Rename with the following command
find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '
s/CONFIG_MMC_SDMA/CONFIG_MMC_SDHCI_SDMA/g
s/CONFIG_BCM2835_SDHCI/CONFIG_MMC_SDHCI_BCM2835/g
s/CONFIG_KONA_SDHCI/CONFIG_MMC_SDHCI_KONA/g
s/CONFIG_MV_SDHCI/CONFIG_MMC_SDHCI_MV/g
s/CONFIG_S5P_SDHCI/CONFIG_MMC_SDHCI_S5P/g
s/CONFIG_SPEAR_SDHCI/CONFIG_MMC_SDHCI_SPEAR/g
'

[2] create the Kconfig entries in drivers/mmc/Kconfig

[3] Move the options by the following command
tools/moveconfig.py -y MMC_SDHCI_SDMA MMC_SDHCI_BCM2835 \
MMC_SDHCI_KONA MMC_SDHCI_MV MMC_SDHCI_S5P MMC_SDHCI_SPEAR

[4] Sort drivers/mmc/Makefile for readability

e1ce61fbba mmc: move CONFIG_SDHCI to Kconfig, renaming to CONFIG_MMC_SDHCI
Move CONFIG_SDHCI to Kconfig and rename it to CONFIG_MMC_SDHCI.
My motivation for the rename is, ultimately, to make all the MMC
options prefixed with MMC_ and SDHCI options with MMC_SDHCI_,
like Linux.

This commit was created as follows:

[1] Rename the config option with the following command:
find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e 's/CONFIG_SDHCI/CONFIG_MMC_SDHCI/g'

[2] create the entry for MMC_SDHCI in drivers/mmc/Kconfig

[3] run "tools/moveconfig.py -y MMC_SDHCI"

[4] add "depends on MMC_SDHCI" to existing SDHCI driver entries

e298c46ac3 mmc: make MMC driver entries dependent on MMC
Currently, CONFIG_MMC is not related to any other options by
"depends on" or "select".  One of big advantages of using Kconfig
is automatic dependency tracking, but the current state is lacking
it.  As the first step, make the existing MMC driver entries depend
on MMC.

This commit was created by the following steps:

[1] Run the following script:

--------------------8<--------------------
rm -f tmp.txt

for d in $(find . -path './configs/*_defconfig')
do
        if grep -q -e 'CONFIG_MSM_SDHCI=y' $d ||
           grep -q -e 'CONFIG_ATMEL_SDHCI=y' $d ||
           grep -q -e 'CONFIG_ROCKCHIP_DWMMC=y' $d ||
           grep -q -e 'CONFIG_SH_SDHI=y' $d ||
           grep -q -e 'CONFIG_PIC32_SDHCI=y' $d ||
           grep -q -e 'CONFIG_ZYNQ_SDHCI=y' $d ||
           grep -q -e 'CONFIG_ROCKCHIP_SDHCI=y' $d ||
           grep -q -e 'CONFIG_MMC_UNIPHIER=y' $d ||
           grep -q -e 'CONFIG_SANDBOX_MMC=y' $d
        then
                echo CONFIG_MMC=y >> $d
                echo ${d#./configs/} >> tmp.txt
        fi
done

tools/moveconfig.py -y -s -d tmp.txt
rm tmp.txt
--------------------8<--------------------

[2] surround MMC driver entries with "if MMC" and "endif"
