afdce76863 mmc: am654_sdhci: Add the quirk to set TESTCD bit
The ARASAN MMC controller on Keystone 3 class of devices need the SDCD
line to be connected for proper functioning.

In cases where this can't be connected, add a quirk to force the
controller into test mode and set the TESTCD bit. Use the flag
"ti,fails-without-test-cd", to implement this above quirk when required.

Additionally, this quirk also avoids waiting for the controller debounce
time.

This commit is similar to linux kernel commit c7666240ec76
("drivers: mmc: sdhci_am654: Add the quirk to set TESTCD bit").

475aa8345a Merge patch series "mediatek: cumulative trivial fix for OF_UPSTREAM support"
Christian Marangi <ansuelsmth@gmail.com> says:

This is an initial series that have all the initial trivial
fixes required for usage of OF_UPSTREAM for the mediatek SoC

This also contains the pcie-gen3 driver and the required tphy
support driver to make it work.

Subsequent series will follow with conversion of the mtk-clk
to permit usage of OF_UPSTREAM and upstream clk ID.

MT7981, MT7986 and MT7988 migration to upstream clock ID
is complete and working on MT7623.

Currently the sdhci_am654 driver only supports one tuning
algorithm which should be used only when DLL is enabled. The
ITAPDLY is selected from the largest passing window and the

The new tuning algorithm should be used when the delay chain

window and the buffer is not viewed as a circular buffer.

This implementation is based off of the following paper: [1].

Also add support for multiple failing windows.

The commit 2cc6cde647e2 ("mmc: rockchip_sdhci: Limit number of blocks

read to fix a Data End Bit Error on RK3568 and RK3588. This had a side
affect of significant slowing down reading FIT from eMMC.

After the commit 6de9d7b2f13c ("rockchip: rk35xx: Enable eMMC HS200 mode

longer necessary and at HS200+ a Data End Bit Error is no longer
happening using PIO mode.

Change this limitation to allow reading more than 4 blocks with a single
CMD18 command in PIO mode at HS200+ speed, keep using the 4 blocks
limitation when loadig FIT from eMMC at lower speed than HS200.

1776213dad mmc: arm_pl180: Limit data transfer to U16_MAX
Currently fetching files bigger that cause a data transfer greater than
U16_MAX fails.

The reason is that the specification defines the datalength register
as a 16 bit wide register, but in u-boot it is used as if it is an
32 bit register. Therefore values greater than U16_MAX cause an
infinite loop inside u-boot. U-boot expects to get more data from
interface/hardware then it will ever get and therefore inifintely waits
for more data that will never come.

5359cd1135 mmc: Support 32-bit only ADMA on 64-bit platforms
Some arm64 platforms may include SDIO host controllers that
only support 32-bit ADMA. While the Linux kernel detects which
size is supported and adjusts the descriptor size used dynamically,
the previous u-boot implementation statically selected between the
two depending on whether DMA_ADDR_T_64BIT was defined. Because the
static selection is already in place and effective for most platforms,
this patch logically separates "64 bit addresses are used for DMA on
this platform" and "64 bit addresses are used by the SDIO host
controller for ADMA" in order to support the small number of platforms
where these statements are not equivalent.

Using 32 bits is opt-in and existing 64 bit platforms should be
unaffected by this change.

The above is a port of Linux kernel commit 54552e4948cbf

In addition, allow drivers to allocate their own ADMA descriptor
tables if additional space is required.

Finally, fix the assignment of adma_addr to fix compiler warning
on 64-bit platforms that still use 32-bit DMA addressing.

SCC settings itself in execute_tuning callback.

When renesas_sdhi_execute_tuning() is called by the MMC core code, a loop
which consists of renesas_sdhi_prepare_tuning(), mmc_send_tuning() and
renesas_sdhi_compare_scc_data() iterates over each SCC tuning tap.

The renesas_sdhi_prepare_tuning() configures the SCC tuning tap number into
hardware, mmc_send_tuning() triggers transfer of tuning block which depends
on the bus mode for which the bus is currently being tuned, this information
is supplied by the MMC core code, and finally renesas_sdhi_compare_scc_data()
tests the received tuning block for validity.

Because renesas_sdhi_prepare_tuning() configures the SCC tuning tap into
the hardware to fit the tuning operation, mmc_send_tuning() which triggers
command transfer using renesas_sdhi_send_cmd() must not manipulate with
the SCC in any way. Currently renesas_sdhi_send_cmd() does unconditionally
call renesas_sdhi_check_scc_error(), which may adjust the SCC tuning tap
position by writing RENESAS_SDHI_SCC_TAPSET, which would overwrite the
required tuning configuration set by renesas_sdhi_prepare_tuning() and
disrupt the tuning operation.

Fix this by skipping the renesas_sdhi_check_scc_error() call in case the
MMC subsystem is in tuning state. This way, the SCC settings are left
unmodified by command transfer during tuning operation.

12859c2219 mmc: renesas-sdhi: Stop transmission in case tuning block transfer fails
The current code uses the state of tuning block received by SCC to
determine whether or not to send transmission stop command. This is
not correct. Use the state of tuning block transfer to determine
whether or not to send transmission stop command instead, because
the transmission stop command has to be sent in case the tuning
block transfer failed.

This requires two changes, separate variable to store and check the
state of tuning block received by SCC, and another separate variable
to store and check return value from transmission stop command.

60649a8d6c mmc: tmio: Check INFO1 for completion during DMA transfer
In case a CRC error occurs during DMA transfer, the transfer completion
flag is not set in TMIO_SD_DMA_INFO1 and the transfer would eventually
time out. The timeout could be very long in case the transfer consists
of a large amount of blocks, the base timeout is 10 seconds and every
block adds 100 us more.

In case a CRC error does occur, a completion flag is set in a different
register, TMIO_SD_INFO1. Use this other completion flag to detect DMA
transfer ended and stop waiting for TMIO_SD_DMA_INFO1 completion flag.
This reduces the lengthy timeout in case of an error. The unconditional
check of TMIO_SD_DMA_INFO2 register for DMA related errors must not be
skipped in any case to actually recognize the DMA error and report it.

ee6cee125a mmc: arm_pl180_mmci: Rely on DM
The PL180/MMCI driver is implied to use CONFIG_DM and the ARM
defconfigs such as configs/vexpress_ca9x4_defconfig will get it
as well.

With a simple oneline to default to not being the v2 variant,
the original ARM MMCI variant works fine with the driver as well.
The IP version actually needs to be read out from a register on
the ARM versions, but we will simply assume we are running on the
original hardware if arm,primecell-periphid is not explicitly
specified in the device tree.

Drop the !CONFIG_DM code and depend on DM_MMC.

Tested on the Versatile Express CA9x4 board.
