b6a0427554 Revert "mmc: fsl_esdhc: fix sd/mmc ddr mode clock setting issue"
This reverts commit 72a89e0da5, which
causes the imx53 HSC to hang as the eMMC is not working properly anymore.

The exact error message:
MMC write: dev # 0, block # 2, count 927 ... mmc write failed
0 blocks written: ERROR

imx53 is not using the DDR mode.

Debugging of pre_div and div generation showed that those values are
generated in a way, which is not matching the ones from working setup.

As the original patch was performing code refactoring, let's revert this
change, so all imx53 boards would work again.

37cb626da2 mmc: sdhci: Add Support for ADMA2
The Standard Host Controller Interface (SDHCI) specification version
3.00 adds support for Advanced DMA (ADMA) for both 64 and 32 bit widths
of DMA. ADMA2 uses a table of descriptors for aggregating DMA requests.
This significantly improves read and write throughput.

Add Support for the same.

bdb5df1a06 mmc: dw_mmc: Round up descriptor end to nearest multiple of cacheline size
The driver currently calculates the end address of cache flush operation
for the DMA descriptors by adding cacheline size to the start address of
the last DMA descriptor. This is not safe, as the cacheline size may be,
in some unlikely cases, smaller than the DMA descriptor size. Replace the
addition with roundup() applied on the end address of the last DMA
descriptor to round it up to the nearest cacheline size multiple.

The bounce_buffer_start() can return -ENOMEM in case memory allocation

the possibly unaligned input address, and the cache maintenance operations
were not applied to this address. This could cause subtle problems. Add

4e16f0a67d mmc: dw_mmc: Calculate timeout from transfer length
The current 4-minute data transfer timeout is misleading and broken.
Instead of such a long wait, calculate the timeout duration based on
the length of the data transfer. The current formula is the transfer
length in bits, divided by a multiplication of bus frequency in Hz,
bus width, DDR mode and converted the mSec. The value is bounded from
the bottom to 1000 mSec.

c406a47431 mmc: stm32_sdmmc2: Fix r1b timeout issue
On response type r1b, if DTIME is not defined or too short,
the Datatimeout and DPSM flag occurs. Like the DPSM is
activated all next data transfer will be frozen.
To avoid this freeze:
    -The driver must define a DTIME on all r1b response type.
    -DTIME of SDMMC must be defined for alls stop transmission
     (for read and write request) even if MMC_RSP_BUSY is not set.
    -If busy timeout occur, an abort request must be sent to
     reinitialize the DPSM.

5cf12031a4 mmc: correct the HS400 initialization process
After the commit b9a2a0e2e9 ("mmc: Add support for downgrading
HS200/HS400 to HS mode"), it add a parameter in mmc_set_card_speed()
which indicates that the HS200/HS400 to HS downgrade is happening.

During the HS400 initialization, first select to HS200, and config
the related clock rate, then downgrade to HS mode. So here also need
to config the downgrade value to be true for two reasons. First,
make sure in the function mmc_set_card_speed(), after switch to HS
mode, first config the clock rate, then read the EXT_CSD, avoid
receiving data of EXT_CSD in HS mode at 200MHz. Second, after issue
the MMC_CMD_SWITCH command, it need to wait a bit then switch bus
properties.

Test on i.MX8QM MEK board, some Micron eMMC will stuck in transfer
mode in this case, and USDHC will never get data transfer complete
status, cause the uboot hang.

Errata i929 in certain OMAP5/DRA7XX/AM57XX silicon revisions
(SPRZ426D - November 2014 - Revised February 2018 [1]) mentions
unexpected tuning pattern errors. A small failure band may be present
in the tuning range which may be missed by the current algorithm.
Furthermore, the failure bands vary with temperature leading to
different optimum tuning values for different temperatures.

As suggested in the related Application Report (SPRACA9B - October 2017
- Revised July 2018 [2]), tuning should be done in two stages.
In stage 1, assign the optimum ratio in the maximum pass window for the
current temperature. In stage 2, if the chosen value is close to the
small failure band, move away from it in the appropriate direction.

6892550c4a mmc: Do not poll using CMD13 when changing timing
When using CMD6 to switch eMMC card timing from HS200/HS400 to HS/legacy,
do not poll for the completion status using CMD13, but rather wait 50mS.

Once the card receives the CMD6 and starts executing it, the bus is in
undefined state until both the card finishes executing the command and
until the controller switches the bus to matching timing configuration.
During this time, it is not possible to transport any commands or data
across the bus, which includes the CMD13.

cbbe69483e mmc: tmio: renesas: Add 1uS delay after DMA completion on older IPs
The internal DMAC asserts DMA transfer end bit too early on older
version of the TMIO IPs which use bit 17 for DTRAEND. Add 1uS
delay after the completion of DMA transfer and before invalidating
the cache to let the DMAC fully complete the transfer. Otherwise,
it could happen that the last few bytes of a transferred data are
not available.

A test case to trigger this behavior is the following command, ran
on the U-Boot command line, with Sandisk 16 GiB UHS-I card inserted
into SDHI slot 0 and with first partition being of type FAT:
=> while true ; do mmc rescan ; fstype mmc 0:1 ; done

992bcf4f27 mmc: tmio: Make DMA transfer end bit configurable
Different versions of the SDHI core use either bit 17 or bit 20 for the
DTRAEND indication, which can differ even between SoC revisions. Make
the DTRAEND bit position part of the driver private data, so that the
probe function can set this accordingly. Set this to 20 on Socionext
SoCs and either 17 or 20 on Renesas SoCs, depending on the SoC.

4233698dd3 mmc: sunxi: Honour non-removable property in DT
If a board DT describes a cd-gpios property, but also marks the storage
as non-removable, we must ignore the GPIO (as Linux does).

Teach the DM_MMC part of the Allwinner MMC driver about the
non-removable DT property, to fix DM_MMC access on the SoPine and
Pine64-LTS board.

c57572eb5a mmc: sunxi: Add DM clk and reset support
Now that we have the gate clocks and the reset gates in our new
Allwinner clock driver, let's make use of them in the MMC driver, when
DM_MMC is defined.
We treat the reset device as optional now, as the older SoCs don't
implement it.
