This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.
I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

Commit 737f360d5bef5e01c6cfa755dca0b449a154c1e0
"regulator: Remove support for supplies specified by struct device"
caused this file to break, since it was still relying on the
device field to be present. Map it onto dev_name appropriately
Since there are two consumers with the name "reg-userspace-consumer",
we have to supply the ID as a suffix in the REGULATOR_CONSUMER calls.

"regulator: Remove support for supplies specified by struct device"

Currently if a platform wants to implement a non-standard card-detection
method, it would need to call tmio_mmc_cd_wakeup(), which is an inline
function, calling mmc_detect_change(). For this the platform would have
to link mmc_core statically into the kernel, losing the ability to build
it as a module. This patch adds a callback to the sh_mobile_sdhi driver,
which eliminates this dependency.

On sh-mobile platforms the MMC clock frequency for the TMIO MMC unit is
obtained from the same clock, as the one, that runtime power-manages the
controller. The SDHI glue code has to access that clock directly,
bypassing the runtime PM framework, to get its frequency, but it
shouldn't enable or disable it.

When using MSI it is possible that a new MSI is sent while an earlier
MSI is currently handled. In this case SDHCI_INT_STATUS only contains
SDHCI_INT_RESPONSE and the ISR would not be called again. But at the end
of the ISR SDHCI_INT_DATA_END is now also pending which would be ignored.
Fix this by rereading the interrupt flags in the ISR until no interrupt
we care is pending.

Someone could use send_hpi_cmd() on a card that doesn't advertise support
for HPI. Then maybe didn't work fine. Because card->ext_csd.hpi_cmd
didn't set. So if card didn't support hpi, return the warning message.
And CMD12's flags is MMC_RSP_R1B.

For small size non-dma sdio transactions, it is sometimes better to poll
the mmc host and avoid interrupts altogether. Polling lowers the number
of interrupts and context switches. Tests have shown that for small
transactions, only a few polling iterations are needed, so this is worth
while.

The davinci mmc interrupt handler fills the fifo, as long as the DXRDY
or DRRDY bits are set in the status register.
If interrupts fire during this loop, they will be handled by the
handler, but the interrupt controller will still buffer these. As a
result, the handler will be called again to serve these needlessly. In
order to avoid these spurious interrupts, keep interrupts masked while
filling the fifo.

When booting with Device tree, the omap_hsmmc driver does not
program the pbias cell (inside OMAP control module) during
a regulator voltage change.
In case of non-dt boot, this is handled using callbacks
from within platform_data and implemented in machine code.
To be able to do this with device tree, without invoking
any machine code, a OMAP control module driver is needed
which is yet missing.
The pbias cell is used to provide a 1.8v or 3.0v reference
to the mmc/sd/sdio1 interface supporting both 1.8v and 3.0v
voltages.
Until a OMAP control module driver is available to handle this,
when booting with a device tree blob, never change the regulator
voltage which might then require a pbias cell re-program.
There are 2 instances where in the mmc regulator voltage can be
changed.
-1- when the regulator is turned OFF.
-2- when attempting a switch to 1.8v from 3.0v for dual volt cards
This patch avoids a voltage change in both cases when booting from
device tree, and hence compromises on power savings.
Once the OMAP control module driver is available and hsmmc driver
is modified to then do pbias programming even when booting
with device tree, these limitaions can be removed to achieve better
power savings.

SDIO is powered separately from the host controller, so the card can
remain on while the host controller is powered off during suspend.

Add quirk SDHCI_QUIRK2_HOST_OFF_CARD_ON to cater for the case when the
card keeps power during suspend but the host controller does not i.e.
the card power is not controlled by the host controller. In that
case, the controller must be fully reset on resume.

This patch fixes following issues when HS200 is enabled:
1. If executing_tuning() host ops is called without mmc_host_clk_hold(),
card clocks might get turned off (if MMC_CLK_GATING is enabled)
while execute_tuning() is in progress. So this patch makes sure
that execute_tuning() is called with mmc_host_clk_hold().
2. If host timing mode is set to HS200 mode, there should not be
any communication with the card until execute_tuning() is completed.
But there is a chance that CMD6 might be sent to enable set HPI_EN
(of HPI_MGMT field in EXT_CSD) before execute_tuning() is called.
So this patch moves this operation after execute_tuning() is completed.

MMC1 is not the only instance that can be used/wired for SD.
So remove this assumption from the driver.
Now that all the mmc id based usage is removed, get rid of all the DEVID
defines and also the 'id' field from the omap_hsmmc_host structure.
