[ Upstream commit ef86cb2059a14b4024c7320999ee58e938873032 ]
This patch fixes a kernel panic for qla2xxx Target core
Module driver introduced by a fix in the qla2xxx initiator code.
Commit ef86cb2 ("qla2xxx: Mark port lost when we receive an RSCN for it.")
introduced the regression for qla2xxx Target driver.

When we open a device file descriptor, we currently have the
following:
vfio_group_get_device_fd()
mutex_lock(&group->device_lock);
open()
...
if (ret)
release()
If we hit that error case, we call the backend driver release path,
which for vfio-pci looks like this:
vfio_pci_release()
vfio_pci_disable()
vfio_pci_try_bus_reset()
vfio_pci_get_devs()
vfio_device_get_from_dev()
vfio_group_get_device()
mutex_lock(&group->device_lock);
Whoops, we've stumbled back onto group.device_lock and created a
deadlock. There's a low likelihood of ever seeing this play out, but
obviously it needs to be fixed. To do that we can use a reference to
the vfio_device for vfio_group_get_device_fd() rather than holding the
lock. There was a loop in this function, theoretically allowing
multiple devices with the same name, but in practice we don't expect
such a thing to happen and the code is already aborting from the loop
with break on any sort of error rather than continuing and only
parsing the first match anyway, so the loop was effectively unused
already.

T3 HW only supports 32 bit MRs. If the system uses 64 bit memory
addresses, then a registered 32 bit MR will wrap and write to the
wrong memory when used with addresses > 4GB. To prevent this,
simply fail to allocate an MR on 64 bit machines (other means
of registering memory are still available and software can still
work, we just don't allow this means of memory registration).

DMA transfers must be greater than the watermark level size. spi_imx->rx_wml
and spi_imx->tx_wml contain the watermark level in 32bit words whereas struct
spi_transfer contains the transfer len in bytes. Fix the check if DMA is
possible for a transfer accordingly. This fixes transfers with sizes between

Device tree provides option to specify the max freqency with property
"max-frequency" in dts and common parse function mmc_of_parse() will
parse it and use this value to set host->f_max to tell the MMC core
the maxinum frequency the host works.
However, current sdhci driver will finally overwrite this value with
host->max_clk regardless of the max-frequency property.
This patch makes sure not overwrite the max-frequency set from device
tree and do basic sanity check.

This is an incremental fix of commit
e62bd351b("mmc: sdhci-esdhc-imx: Do not break platform data boards").
After commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()"),
we do not need to run the check of boarddata->wp_type/cd_type/max_bus_width
again for dt platform since those are already handled by mmc_of_parse().
Current code only exclude the checking of wp_type for dt platform which
does not make sense.
This patch moves all non dt probe code into one function.
Besides, since we only support SD3.0/eMMC HS200 for dt platform, the
support_vsel checking and ultra high speed pinctrl state are also merged
into sdhci_esdhc_imx_probe_dt.
Then we have two separately probe function for dt and non dt type.
This can make the driver probe more clearly.

Current card detect probe process is that when driver finds a valid
ESDHC_CD_GPIO, it will clear the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION
which is set by default for all esdhc/usdhc controllers.
Then host driver will know there's a valid card detect function.
Commit 8d86e4fcccf6 ("mmc: sdhci-esdhc-imx: Call mmc_of_parse()")
breaks GPIO CD function for dt platform that it will return directly
when find ESDHC_CD_GPIO for dt platform which result in the later wrongly
to keep SDHCI_QUIRK_BROKEN_CARD_DETECTION for all dt platforms.
Then MMC_CAP_NEEDS_POLL will be used instead even there's a valid
GPIO card detect.
This patch adds back this function and follows the original approach to
clear the quirk if find an valid CD GPIO for dt platforms.
