This reverts commit 942b5fc032.
This is partial revert of the above commit.
mmc_of_parse() is reading no-1-8-v from device tree and if set,
it is clearing the UHS speed capabilities of cfg->host_caps.
cfg->host_caps &= ~(UHS_CAPS | MMC_MODE_HS200 |
MMC_MODE_HS400 | MMC_MODE_HS400_ES);
This is still missing to clear UHS speeds like SDHCI_SUPPORT_SDR104,
SDHCI_SUPPORT_SDR50 and SDHCI_SUPPORT_DDR50.
Even if we clear the flags SDHCI_SUPPORT_XXX in mmc_of_parse(),
these speed flags are getting set again in cfg->host_caps in
sdhci_setup_cfg().
The reason for this is, SDHCI_SUPPORT_XXX flags are cleared
only if controller is not capable of supporting MMC_VDD_165_195 volts.
if (caps & SDHCI_CAN_VDD_180)
cfg->voltages |= MMC_VDD_165_195;
if (!(cfg->voltages & MMC_VDD_165_195))
caps_1 &= ~(SDHCI_SUPPORT_SDR104 | SDHCI_SUPPORT_SDR50 |
SDHCI_SUPPORT_DDR50);
It means "no-1-8-v", which is read from DT is not coming in to effect.
So it is better we keep the host quirks(SDHCI_QUIRK_NO_1_8_V) to
clear UHS speeds based on no-1-8-v from device tree.
Hence revert the functionality related to no-1-8-v only, rest is fine
in the patch.

There was a fix-up for eMMC HS400 stability issue in Linux.
Patch link:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/
commit/?id=58d0bf843b49fa99588ac9f85178bd8dfd651b53
Description:
Currently only LX2160A eSDHC supports eMMC HS400. According to
a large number of tests, eMMC HS400 failed to work at 150MHz,
and for a few boards failed to work at 175MHz. But eMMC HS400
worked fine on 200MHz. We hadn't found the root cause but
setting eSDHC_DLLCFG0[DLL_FREQ_SEL] = 0 using slow delay chain
seemed to resovle this issue. Let's use this as fixup for now.
Introduce the fix-up in u-boot since the issue could be reproduced
in u-boot too.

Since the introduction of 'get_cd' callback in sdhci core,
dragonboard410c's MMC interface is broken. It turns out that 'get_cd'
callback checks for the host_caps for validating the chip select. And
since the msm_sdhci driver is not parsing the host_caps from DT, not
all of the cababilities are parsed properly. This results in the MMC
interfaces to be broken.
Hence, fix this by adding a call to 'mmc_of_parse' during driver probe.

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:
It's a **mistake** to use typedef for structures and pointers.
Besides, using typedef for structures is annoying when you try to make
headers self-contained.
Let's say you have the following function declaration in a header:
void foo(bd_t *bd);
This is not self-contained since bd_t is not defined.
To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h>
#include <asm/u-boot.h>
void foo(bd_t *bd);
Then, the include direcective pulls in more bloat needlessly.
If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:
struct bd_info;
void foo(struct bd_info *bd);
Right, typedef'ing bd_t is a mistake.
I used coccinelle to generate this commit.
The semantic patch that makes this change is as follows:

In the current implementation, when dtoc parses a dtb to generate a struct
platdata it converts the information related to linked nodes as pointers
to struct platdata of destination nodes. By doing this, it makes
difficult to get pointer to udevices created based on these
information.
This patch extends dtoc to use struct driver_info when populating
information about linked nodes, which makes it easier to later get
the devices created. In this context, reimplement functions like
clk_get_by_index_platdata() which made use of the previous approach.

Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.
To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.
In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

In current code, we add 1ms dealy after each tuning command for standard
tuning method. Adding this 1ms dealy is because USDHC default check the
CMD CRC and DATA line. If detect the CMD CRC, USDHC standard tuning
IC logic do not wait for the tuning data sending out by the card, trigger
the buffer read ready interrupt immediately, and step to next cycle. So
when next time the new tuning command send out by USDHC, card may still
not send out the tuning data of the upper command，then some eMMC cards
may stuck, can't response to any command, block the whole tuning procedure.
If do not check the CMD CRC for tuning, then do not has this issue. USDHC
will wait for the tuning data of each tuning command and check them. If the
tuning data pass the check, it also means the CMD line also okay for tuning.
So this patch disable the CMD CRC check for tuning, save some time for the
whole tuning procedure.

The 3V3/1V8 switching could never have worked on any of the iMXes

because that commit uses priv->vqmmc_dev when switching voltages on
mode switch, while local vqmmc_dev in probe to store the regulator
pointer. Those are two different variables with the same name. So
the priv->vqmmc_dev was always NULL and thus voltage switch between
modes never really suceeded.
Fix this by assigning priv->vqmmc_dev with value of the vqmmc_dev
in probe.

When eSDHC operates at 3.3v, damage can accumulate in an internal
level shifter at a higher than expected rate. The faster the interface
runs, the more damage accumulates. This issue now is found on LX2160A
eSDHC1 for only SD card.
The hardware workaround is recommended to use an on-board level shifter
that is 1.8v on SoC side and 3.3v on SD card side.
For boards without hardware workaround, this option could be enabled,
ensuring 1.8v IO voltage and disabling eSDHC if no card.
This option assumes no hotplug, and u-boot has to make all the way to
to linux to use 1.8v UHS-I speed mode if has card.
If you do not want the workaround for better user experience, of course
you can choose to not select it running eSDHC in unsafe mode.

1. Move all platdata assignment from probe() to ofdata_to_platdata().
This function is only called in U-boot.
2. Replicate all the platdata assignment being done in
ofdata_to_platdata() in the omapl138 board file. This data is used in
the SPL case where SPL_OF_CONTROL is not enabled.
3. Remove SPL_OF_CONTROL and related configs from omapl138_lcdk_defconfig
