During test campaign, and especially after several unbind/bind sequences,
it has been seen that the SD-card on SDMMC1 thread could freeze.
The freeze always appear on a CMD23 following a CMD19.
Checking SDMMC internal registers shows that the tuning command (CMD19)
has failed.
The freeze is then due to the delay block involved in the tuning sequence.
To correct this, clear the delay block register DLYB_CR register after

It's seems prone to problems by allowing card detect and its corresponding
mmc_rescan() work to run, during platform shutdown. For example, we may end
up turning off the power while initializing a card, which potentially could
damage it.
To avoid this scenario, let's add ->shutdown_pre() callback for the mmc host
class device and then turn of the card detect from there.

In mmc_send_op_cond(), loops are continuously performed at the same
interval of 10 ms. However the behaviour is not good for some eMMC
which can be out from a busy state earlier than 10 ms if normal.
Rather than fixing about the interval time in mmc_send_op_cond(),
let's instead convert into using the common __mmc_poll_for_busy().
The reason for adjusting the interval time is that it is important
to reduce the eMMC initialization time, especially in devices that
use eMMC as rootfs.

The TiWi WL1251 WiFi chip needs special setup of the sdio
interface before it can be probed.
So far, this is done in omap_hsmmc_init_card() in omap_hsmmc.c
which makes it useable only if connected to omap devices
which use the omap_hsmmc. The OpenPandora is the most promient
example.
There are plans to switch to a newer sdhci-omap driver and
retire omap_hsmmc. Hence this quirk must be reworked or moved
somewhere else. Ideally to some location that is not dependent
on the specific SoC mmc host driver.
This is achieved by the new mmc_fixup_device() option introduced
by ("mmc: allow to match the device tree to apply quirks") to match
through device tree compatible string.
This quirk will be called early right after where host->ops->init_card()
and thus omap_hsmmc_init_card() was previously called.
Note that we do not need to transplant
card->ocr = 0x80;
because we rely on ("mmc: core: Fixup storing of OCR for MMC_QUIRK_NONSTD_SDIO").

The mmc core takes a specific path to support initializing of a
non-standard SDIO card. This is triggered by looking for the card-quirk,
MMC_QUIRK_NONSTD_SDIO.
In mmc_sdio_init_card() this gets rather messy, as it causes the code to
bail out earlier, compared to the usual path. This leads to that the OCR
doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has
been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by
assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.
To make the behaviour consistent, let's instead rely on the core to save
the OCR in card->ocr during initialization.

dev_t. In fact except for the ioctl method drivers never even see
partitions in normal operation.
So remove the GENHD_FL_EXT_DEVT and allow extra partitions for all
block devices that do support partitions, and require those that
do not support partitions to explicit disallow them using
GENHD_FL_NO_PART.

This manually reverts 07b652cdbec3 ("mmc: card: Don't show eMMC RPMB and
BOOT areas in /proc/partitions"). Based on the commit description that
change was purely cosmetic. mmc is the last driver that sets this
flag and thus prevents it from being removed.

The GENHD_FL_NO_PART_SCAN controls more than just partitions canning,
so rename it to GENHD_FL_NO_PART.

Commit 5fa6863ba692 ("spi: Check we have a spi_device_id for each DT
compatible") added a test to check that every SPI driver has a
spi_device_id for each DT compatiable string defined by the driver
and warns if the spi_device_id is missing. The spi_device_id is
missing for the MMC SPI driver and the following warning is now seen.
WARNING KERN SPI driver mmc_spi has no spi_device_id for mmc-spi-slot
Fix this by adding the necessary spi_device_id.

Like the individual CCU drivers, it can be beneficial for memory
consumption of cross-platform configurations to only load the CCU core
on the relevant platform. For example, a generic arm64 kernel sees the
following improvement when building the CCU core and drivers as modules:
before:
text data bss dec hex filename
13882360 5251670 360800 19494830 12977ae vmlinux
after:
text data bss dec hex filename
13734787 5086442 360800 19182029 124b1cd vmlinux
So the result is a 390KB total reduction in kernel image size.
The one early clock provider (sun5i) requires the core to be built in.
Now that loading the MMC driver will trigger loading the CCU core, the
MMC timing mode functions do not need a compile-time fallback.
