While performing R/W access in PIO mode, the common SDHCI driver checks
the buffer ready status once per whole block processing. That is, after
getting an appropriate interrupt, or checking an appropriate status bit,
the driver makes buffer accesses for the whole block size (e.g. 128 reads
for 512 bytes block). This is done in accordance with SD Host Controller
Specification.
At the same time, the Ultra Secured Digital Host Controller (uSDHC), used
in i.MX6 (and, probably, earlier i.MX series too), uses a separate
Watermark Levels register, controlling the amount of data or space
available when raising status bit or interrupt. For default watermark
setting of 16 words, the controller expects (and guarantees) no more
than 16 buffer accesses after raising buffer ready status bit and
generating an appropriate interrupt. If the driver tries to access the
whole block size, it will get incorrect data at the end, and a new
interrupt will appear later, when the driver already doesn't expect it.
This happens sometimes, more likely on low frequencies, e.g. when
reading EXT_CSD at MMC card initialization phase
(which makes that initialization fail).
Such behavior of i.MX uSDHC seems to be non-compliant
to SDHCI Specification, but this is the way it works now.
In order not to rewrite the SDHCI driver PIO mode access logic,
the IMX specific driver can just set the watermark level to default
block size (128 words or 512 bytes), so that the controller behavior
will be consistent to generic specification. This patch does this
for PIO mode accesses only, restoring default values for DMA accesses
to avoid any possible side effects from performance point of view.

The PADs for SD card are dual-voltage that support 3v/1.8v. Those PADs
have a control signal (io_pad_pwr_switch/mode18 ) that indicates
whether the PAD works in 3v or 1.8v.
SDHC core on msm platforms should have IO_PAD_PWR_SWITCH bit set/unset
based on actual voltage used for IO lines. So when power irq is
triggered for io high or io low, the driver should check the voltages
supported and set the pad accordingly.

Currently, the code block inside the for loop will never execute more than
once, because the function returns immediately after the first iteration,
hence the execution of the code at the second iteration is structurally
dead and, code at line 281: return 0; is never reached.
Fix this by checking _ret_ before return.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.

So far, even if our card was not in use, we didn't shut down our MMC
controller, which meant that it was still active and clocking the bus.
While this obviously means that we could save some power there, it also
creates issues when it comes to EMC control since we'll have a perfect peak
at the card clock rate.
Let's implement runtime_pm with autosuspend so that we will shut down the
controller when it's not been in use for quite some time.

Cadence sent out an errata report to their customers of this IP.
This errata is not so severe, but the tune request should be sent
twice to avoid the potential issue.
Quote from the report:
Problem Summary
---------------
The IP6116 SD/eMMC PHY design has a timing issue on receive data path.
This issue may lead to an incorrect values of read/write pointers of
the synchronization FIFO. Such a situation can happen at the SDR104
and HS200 tuning procedure when the PHY is requested to change a phase
of sampling clock when moving to the next tuning iteration.
Workarounds
-----------
The following are valid workarounds to resolve the issue:
1. In eMMC mode, software sends tune request twice instead of once at
each iteration. This means that the clock phase is not changed on
the second request so there is no potential for clock instability.
2. In SD mode, software must not use the hardware tuning and instead
perform an almost identical procedure to eMMC, using the HRS34 Tune
Force register.

Add support for the JZ4780 MMC controller to the jz47xx_mmc driver. There
are a few minor differences from the 4740 to the 4780 that need to be
handled, but otherwise the controllers behave the same. The IREG and IMASK
registers are expanded to 32 bits. Additionally, some error conditions are
now reported in both STATUS and IREG. Writing IREG before reading STATUS
causes the bits in STATUS to be cleared, so STATUS must be read first to
ensure we see and report error conditions correctly.

The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
(kernel Oops) or a security flaw (overwriting memory beyond the
stack). Also, in general, as code evolves it is easy to lose track of
how big a VLA can get. Thus, we can end up having runtime failures
that are hard to debug. As part of the directive[1] to remove all VLAs
from the kernel, and build with -Wvla.
Currently driver is using a VLA declared using the number of descriptors. This
array is used to store integer values and is later used as an argument to
`gpiod_set_array_value_cansleep()` This can be avoided by using
`kmalloc_array()` to allocate memory for the array of integer values. Memory is
free'd before return from function.
>From the code it appears that it is safe to sleep so we can use GFP_KERNEL
(based _cansleep() suffix of function `gpiod_set_array_value_cansleep()`.
It can be expected that this patch will result in a small increase in overhead
due to the use of `kmalloc_array()`

On SD 2.00 cards we get lots of these messages:
"mmc0: Got data interrupt 0x00000002 even though no data operation was in progress"
By applying the SDHCI_QUIRK2_STOP_WITH_TC quirk, the messages no longer happen.
A single card claiming to be SD 3.00 compliant also generates the interrupts,
but since the card's manfacturing date is 2002 mar, it's unlikely to really be
SD 3.00. This card is a 8GB SanDisk 'SU08G' 8.0 (SDHC class 4).
This has been reported on Xilinx devices that also use the Arasan IP.
See https://patchwork.kernel.org/patch/8062871/
This has been tested on the Renesas RZ/ND-DB board with the RZ/N1 SoC. The
Arasan IP in this device is version 1.39a and uses a max SD clock of 50MHz and

Pull driver core fixes from Greg Kroah-Hartman:
"Here are some small driver core and firmware fixes for 4.17-rc3
There's a kobject WARN() removal to make syzkaller a lot happier about
some "normal" error paths that it keeps hitting, which should reduce
the number of false-positives we have been getting recently.
There's also some fimware test and documentation fixes, and the
coredump() function signature change that needed to happen after -rc1
before drivers started to take advantage of it.
All of these have been in linux-next with no reported issues"

"Here are a number of USB driver fixes for reported problems for
4.17-rc3.
