d2c05f50e1 mmc: omap_hsmmc: Set 3.3V for IO voltage

351a4aa050 mmc: omap_hsmmc: Workaround errata regarding SDR104/HS200 tuning failures (i929)
Errata i929 in certain OMAP5/DRA7XX/AM57XX silicon revisions
(SPRZ426D - November 2014 - Revised February 2018 [1]) mentions
unexpected tuning pattern errors. A small failure band may be present
in the tuning range which may be missed by the current algorithm.
Furthermore, the failure bands vary with temperature leading to
different optimum tuning values for different temperatures.

As suggested in the related Application Report (SPRACA9B - October 2017
- Revised July 2018 [2]), tuning should be done in two stages.
In stage 1, assign the optimum ratio in the maximum pass window for the
current temperature. In stage 2, if the chosen value is close to the
small failure band, move away from it in the appropriate direction.

223b10ca7a mmc: omap: Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

reset procedure section in TRM suggests to first poll the SRD/SRC bit
until it is set to 0x1. But looks like that bit is never set to 1 and there
is an observable delay of 1sec everytime the driver tries to reset DAT/CMD.
(The same is observed in linux kernel).

Reduce the time the driver waits for the controller to set the SRC/SRD bits
to 1 so that there is no observable delay.

2faa1a302b mmc: omap_hsmmc: Workaround for errata id i802
According to errata i802, DCRC error interrupts
(MMCHS_STAT[21] DCRC=0x1) can occur during the tuning procedure.

The DCRC interrupt, occurs when the last tuning block fails
(the last ratio tested). The delay from CRC check until the
interrupt is asserted is bigger than the delay until assertion
of the tuning end flag. Assertion of tuning end flag is what
masks the interrupts. Because of this race, an erroneous DCRC
interrupt occurs.

The suggested  workaround is to disable DCRC interrupts during
the tuning procedure which is implemented here.

a field (bit 6) named GPIO_IO_PWRDNZ.  If 0, the IO buffers which
are related to GPIO_126, 127 and 129 are disabled. Some boards may
need this for MMC. After the PBIAS is configured, this bit should
be set high to enable these GPIO pins.

e160f7d430 dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

b4b060066f ARM: OMAP4+: Add support for getting pbias info from board
Palmas driver assumes it is always TPS659xx regulator on all DRA7xx based
boards to enable mmc regulator. This is not true always like in case of
DRA71x-evm. So get this information based on the board.

3891a54f47 ARM: DRA7x/AM57xx: Get rid of CONFIG_AM57XX
CONFIG_AM57XX is just an unnecessary macro that is redundant given So,
remove the same instead of spreading through out the u-boot source
code and getting in the way to maintain common code for DRA7x family.
