One of Renesas SDHI chip needs workaround to use it, and, we can judge
it based on chip version. This patch adds very quick-hack workaround
method, since we still don't know how many chips need workaround in
the future.

The accessibility checking method to the higher register was added by
69d1fe18e92afb (mmc: tmio: only access registers above 0xff, if available)
But, it doesn't care 32bit register. It is impossible to calculate it
from the resource size, since there is 16/32 bit register IP (e.g. VERSION
is located on 0xe2 if 16bit register, but it is located on 0x1c4 if 32bit
register).
This patch adds new TMIO_MMC_HAVE_HIGH_REG flags, tmio_mmc driver has it,
and sh_mobile_sdhi doesn't have it today.

.bus_shift is used to 16/32bit register access offset calculation on
tmio driver. tmio_mmc_xxx is used from Toshiba/Renesas now, but this
bus_shift value depends on HW IP. This patch moves .bus_shift to
tmio_mmc_data member and sets it on each driver.

Current tmio driver tries to use default ocr_avail if 1) it couldn't
find regulator and 2) if platform data doesn't have ocr_mask.
But, there is no guarantee that regulator driver probe is faster than
TMIO driver probe. TMIO driver will not use regulator in such case.
By this patch, TMIO driver returns -EPROBE_DEFER if it couldn't find
regulator and if platform doesn't have ocr_mask. Because, there is a
possibility that regulator has not been probed, but the user expects it.
This patch changes tmio_mmc_host_probe() behavior, but there is no user
who has conflict.

In function sdhci_request(), it is possible to do the tuning execution
like below:
sdhci_request() {
spin_lock_irqsave(&host->lock, flags);
host->mrq = mrq;
...
spin_unlock_irqrestore(&host->lock, flags);
<=== Here it is possible one pending finish_tasklet get running
and it will operate the original mrq, and notified the mrq
is done, and causes memory corruption.
sdhci_execute_tuning(mmc, tuning_opcode);
spin_lock_irqsave(&host->lock, flags);
host->mrq = mrq;
...
}
In the above race place, the original mrq should not be finished wrongly,
so here before unlock the spinlock, we need to set the host->mrq to NULL
to avoid this case.

With some SDIO devices, timeout errors can happen when reading data.
To solve this issue, the DMA transfer has to be activated before sending
the command to the device. This order is incorrect in PDC mode. So we
have to take care if we are using DMA or PDC to know when to send the
MMC command.

Under function mmc_blk_issue_rq, after an MMC discard operation,
the MMC request data structure may be freed in memory. Later in
the same function, the check of req->cmd_flags & MMC_REQ_SPECIAL_MASK
is dangerous and invalid. It causes the MMC host not to be released
when it should.
This patch fixes the issue by marking the special request down before
the discard/flush operation.

Current code will clear all turning related bits like ESDHC_STD_TUNING_EN
and ESDHC_MIX_CTRL_FBCLK_SEL when clear SDHCI_CTRL_EXEC_TUNING.
This may cause the card which has already passed the turning to become
unwork since the turning status lost.
We observed this failure when enable runtime pm.
BTW, imx needs to enable ESDHC_MIX_CTRL_FBCLK_SEL bit for turned clock.
The FBCLK_SEL will be cleared when SDHCI_CTRL_TUNED_CLK is cleared
and SDHCI_CTRL_EXEC_TUNING is not set.
This is used in case we change to another normal card from a UHS card
in the same slot. FBCLK_SEL is not needed for normal card.
After that, SDHCI_CTRL_EXEC_TUNING will only affect ESDHC_MIX_CTRL_EXE_TUNE.
Clearing it does not affect the turned card to remain working on UHS mode.

This patch implements the power_down_finish() method for TC2, to
enable the kernel to confirm when CPUs are safely powered down.
The information required for determining when a CPU is parked
cannot be obtained from any single place, so a few sources of
information must be combined:
* mcpm_cpu_power_down() must be pending for the CPU, so that we
don't get confused by false STANDBYWFI positives arising from
CPUidle. This is detected by waiting for the tc2_pm use count
for the target CPU to reach 0.
* Either the SPC must report that the CPU has asserted
STANDBYWFI, or the TC2 tile's reset control logic must be
holding the CPU in reset.
Just checking for STANDBYWFI is not sufficient, because this
signal is not latched when the the cluster is clamped off and
powered down: the relevant status bits just drop to zero. This
means that STANDBYWFI status cannot be used for reliable
detection of the last CPU in a cluster reaching WFI.
This patch is required in order for kexec to work with MCPM on TC2.
MCPM code was changed in commit 0de0d6467525 ('ARM: 7848/1: mcpm:
Implement cpu_kill() to synchronise on powerdown'), and since then it
will hit a WARN_ON_ONCE() due to power_down_finish not being implemented
on the TC2 platform.

This patch defines a new value for the 'ima_show_type' enumerator
(IMA_SHOW_BINARY_NO_FIELD_LEN) to prevent that the field length
is transmitted through the 'binary_runtime_measurements' interface
for the digest field of the 'ima' template.
Fixes commit: 3ce1217 ima: define template fields library and new helpers

To maintain compatibility with userspace tools, the field length must not
be included in the template digest calculation for the 'ima' template.

Fix kernel-doc warning for duplicate definition of 'kmalloc':
Documentation/DocBook/kernel-api.xml:9483: element refentry: validity error : ID API-kmalloc already defined
<refentry id="API-kmalloc">
Also combine the kernel-doc info from the 2 kmalloc definitions into one
block and remove the "see kcalloc" comment since kmalloc now contains the
@flags info.
