The ls1046a datasheet specified that the max SD clock frequency
for eSDHC SDR104/HS200 was 167MHz, and the ls1012a datasheet
specified it's 125MHz for ls1012a. So this patch is to add the
limitation.

The loop to poll ESDHC_CLOCK_STABLE bit with mdelay would waste time
because the time to stabilize is much less than 1 ms. This patch is
to use udelay instead to avoid time wasting.

eSDHC supports signal voltage switch from 3.3v to 1.8v by
eSDHC_PROCTL[VOLT_SEL] bit. This bit changes the value of output
signal SDHC_VS, and there must be a control circuit out of eSDHC
to change the signal voltage according to SDHC_VS output signal.

eSDHC could select peripheral clock or platform clock as clock source by
the PCS bit of eSDHC Control Register, and this bit couldn't be reset by
software reset for all. In default, the platform clock is used. But we have
to use peripheral clock since it has a higher frequency to support eMMC
HS200 mode and SD UHS-I mode. This patch is to add peripheral clock support
and use it instead of platform clock if it's declared in eSDHC dts node.

The eSDHC_PRSSTAT[SDSTB] bit indicates whether the internal card clock is
stable. This bit is for the host driver to poll clock status when changing
the clock frequency. It is recommended to clear eSDHC_SYSCTL[SDCLKEN]
to remove glitch on the card clock when the frequency is changing. This
patch is to disable SDCLKEN bit before changing frequency and enable it
after SDSTB bit is set.

Initially all QorIQ platforms were PowerPC architecture and they didn't
support card detection except several platforms. The driver added the
quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION as default and this made broken-cd
property in dts node didn't work. Now QorIQ platform turns to ARM
architecture and most of them could support card detection. However it's
a large number of dts trees that need to be fixed with broken-cd if we
remove the default SDHCI_QUIRK_BROKEN_CARD_DETECTION in driver. And the
users don't want to see this. So this patch is to remove this default
quirk just for ARM and keep it for PowerPC.(Note, QorIQ PowerPC platform
only has big-endian eSDHC while QorIQ ARM platform has big-endian or
little-endian eSDHC) This makes broken-cd property work again for ARM.

The eSDHC of T4240-R1.0-R2.0 has incorrect vender version and spec version.
Acturally the right version numbers should be VVN=0x13 and SVN = 0x1.

And fix host version to avoid that incorrect version numbers break down

Since commit 87a18a6a5652 ("mmc: mmc: Use ->card_busy() to detect busy
cards in __mmc_switch()") the ESDHC driver is broken:
mmc0: Card stuck in programming state! __mmc_switch
mmc0: error -110 whilst initialising MMC card
Since this commit __mmc_switch() uses ->card_busy(), which is
sdhci_card_busy() for the esdhc driver. sdhci_card_busy() uses the
PRESENT_STATE register, specifically the DAT0 signal level bit. But the
ESDHC uses a non-conformant PRESENT_STATE register, thus a read fixup is
required to make the driver work again.

The commit 0718e59ae259 ("mmc: sdhci: move FSL ESDHC reset handling quirk into

SDHCI_QUIRK_RESTORE_IRQS_AFTER_RESET quirk handling code into the
esdhc-imx driver only. Unfortunately the same controller is used in
other boards which use the of-esdhc driver instead (like powerpc P2020).

We need a lot of imx6 specific things into common esdhc_set_clock

platforms, so esdhc_set_clock seems not so common anymore.
Instead of keeping add platform specfics things into this common API,
we choose to move that code into platform driver itself to handle.
This can also exclude the dependency between imx and power pc on this
headfile and is easy for maintain in the future.

The P2020 has a non-standard implementation of the SDHCI_HOST_CONTROL

a host controller has a non-standard SDHCI_HOST_CONTROL register. The
patch adds a check to the function esdhc_writeb in file
sdhci-of-esdhc.c, where it checks if the write is done to the
SDHCI_HOST_CONTROL register and th host has the above mentioned QUIRK,
then the function simply returns instead of writing to the register.
The patch also detects if the processor is P2020 (by looking in dev
tree) and if so, adds the QUIRK to the host->quirk2

This patch adds support of connecting an MMC media using an 8-bit
bus width connection to Freescale's P2020 H/W SDHC controller. During
the probe function, the generic function mmc_of_parse is called to
detect whether the controller is configured with 8-bit bus width.
Also, the generic function detects if the non-removable property is
set in the device tree. The function esdhc_pltfm_bus_width was added
because the bus width configuration is platform specific.

CMD23 causes lots of errors in kernel on some freescale SoCs
(P1020, P1021, P1022, P1024, P1025 and P4080) when MMC card used,
which is because these controllers does not support CMD23,
even on the SoCs which declares CMD23 is supported.
Therefore, we'll not use CMD23.
