Let a vendor driver supply the maximum descriptor size that it
can operate on. ADMA descriptor table would be allocated using this
supplied size.
If any SD Host controller is of version prior to v4.10 spec
but supports 16byte descriptor, this change allows them to supply
correct descriptor size for ADMA table allocation.
Also let a vendor driver update the descriptor size by overriding
sdhc_host->desc_size if it has to operates on a different descriptor
sizes in different conditions.

Some standard SD host controllers can support both external dma
controllers as well as ADMA/SDMA in which the SD host controller
acts as DMA master. TI's omap controller is the case as an example.
Currently the generic SDHCI code supports ADMA/SDMA integrated in
the host controller but does not have any support for external DMA
controllers implemented using dmaengine, meaning that custom code is
needed for any systems that use an external DMA controller with SDHCI.
Fixes by Faiz Abbas <faiz_abbas@ti.com>:
1. Map scatterlists before dmaengine_prep_slave_sg()
2. Use dma_async() functions inside of the send_command() path and call
terminate_sync() in non-atomic context in case of an error.

Nowadays sdhci prevents runtime suspend when SDIO IRQs are enabled.
However, some variants such as sdhci-esdhc-imx's, tries to allow runtime
suspend while having the SDIO IRQs enabled, but without supporting remote
wakeups. This support is a bit questionable, especially if the host device
have a PM domain attached that can be power gated, but more importantly,
the code have also become redundant (which was not the case when it was
introduced).
Rather than keeping the redundant code around, let's drop it and leave this
to be revisited later on.

The SD host controller specification defines 3 types software reset:
software reset for data line, software reset for command line and software
reset for all. Software reset for all means this reset affects the entire
Host controller except for the card detection circuit.
In sdhci_runtime_resume_host() we always do a software "reset for all",
which causes the Spreadtrum variant controller to work abnormally after
resuming. To fix the problem, let's do a software reset for the data and
the command part, rather than "for all".
However, as sdhci_runtime_resume() is a common sdhci function and we don't
want to change the behaviour for other variants, let's introduce a new
in-parameter for it. This enables the caller to decide if a "reset for all"
shall be done or not.

As per the Host Controller Standard Specification Version 4.20,
limitation of tuning iteration count is removed as PLL locking
time can be longer than UHS-1 tuning due to larger PVT fluctuation
and it will result in increase of tuning iteration to complete the
tuning.
This patch creates sdhci_host member tuning_loop_count to allow
hosts to specify maximum tuning iterations and also updates
execute_tuning to use this specified maximum tuning iteration count.
Default tuning_loop_count is set to same as existing loop count of
MAX_TUNING_LOOP which is 40 iterations.

Below are the supported DMA types in Host Control1 Register
with Version 4 enable
b'00 - SDMA
b'01 - Not Used
b'10 - ADMA2
b'11 - ADMA2 or ADMA3
ADMA3 uses Command Descriptor to issue an SD command.
A multi-block data transfer is performed by using a pair of CMD
descriptor and ADMA2 descriptor.
ADMA3 performs multiple of multi-block data transfer by using
Integrated Descriptor which is more suitable for Command Queuing
to fetch both Command and Transfer descriptors.

As SD Host Controller Specification v4.10 documents:
Host Controller Version 4.10 defines this "Auto CMD Auto Select" mode.
Selection of Auto CMD depends on setting of CMD23 Enable in the Host
Control 2 register which indicates whether card supports CMD23. If CMD23
Enable =1, Auto CMD23 is used and if CMD23 Enable =0, Auto CMD12 is
used. In case of Version 4.10 or later, use of Auto CMD Auto Select is
recommended rather than use of Auto CMD12 Enable or Auto CMD23
Enable.

when using 32-bit block count, 16-bit block count register need

The bounce buffer is gone from the MMC core, and now we found out
that there are some (crippled) i.MX boards out there that have broken
ADMA (cannot do scatter-gather), and also broken PIO so they must
use SDMA. Closer examination shows a less significant slowdown
also on SDMA-only capable Laptop hosts.
SDMA sets down the number of segments to one, so that each segment
gets turned into a singular request that ping-pongs to the block
layer before the next request/segment is issued.
Apparently it happens a lot that the block layer send requests
that include a lot of physically discontiguous segments. My guess
is that this phenomenon is coming from the file system.
These devices that cannot handle scatterlists in hardware can see
major benefits from a DMA-contiguous bounce buffer.
This patch accumulates those fragmented scatterlists in a physically
contiguous bounce buffer so that we can issue bigger DMA data chunks
to/from the card.
When tested with a PCI-integrated host (1217:8221) that
only supports SDMA:
0b:00.0 SD Host controller: O2 Micro, Inc. OZ600FJ0/OZ900FJ0/OZ600FJS
SD/MMC Card Reader Controller (rev 05)
This patch gave ~1Mbyte/s improved throughput on large reads and
writes when testing using iozone than without the patch.
dmesg:
sdhci-pci 0000:0b:00.0: SDHCI controller found [1217:8221] (rev 5)
mmc0 bounce up to 128 segments into one, max segment size 65536 bytes
mmc0: SDHCI controller on PCI [0000:0b:00.0] using DMA
On the i.MX SDHCI controllers on the crippled i.MX 25 and i.MX 35
the patch restores the performance to what it was before we removed
the bounce buffers.

Currently the get_timeout_clock callback doesn't clearly
have a statement that it needs the variant drivers to return
the timeout clock rate in kHz if the SDHCI_TIMEOUT_CLK_UNIT
isn't present, otherwise the variant drivers should return it
in MHz. It's also very likely that further variant drivers which
are going to use this callback will be confused by this situation.
Given the fact that moderm sdhci variant hosts are very prone to get
the timeout clock from common clock framework (actually the only three
users did that), it's more natural to return the value in Hz and we
make an explicit comment there. Then we put the unit conversion inside
the sdhci core. Thus will improve the code and prevent further misuses.
