According to Data Manual(SPRS915P) of AM57x, TI QSPI controller on
DRA74(rev 1.1+)/DRA72 EVM can support up to 64MHz in MODE-0, whereas
MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better
throughput.

DRA7 family of processors from Texas Instruments, have a hardware module
called IODELAYCONFIG Module which is expected to be configured. This
block allows very specific custom fine tuning for electrical
characteristics of IO pins that are necessary for functionality and
device lifetime requirements. IODelay module has it's own register space
with registers to configure various pins.

According to AM572x TRM SPRUHZ6E October 2014–Revised January 2016[1]
section 18.4.6.1 Pad Configuration, in addition to pinmuxing(MUXMODE),
when operating a pad in certain mode, Virtual/Manual IO Timing Mode must
also be configured to ensure that IO timings are met (DELAYMODE and
MODESELECT fields of pad's IODELAYCONFIG module register). According to
section 18.4.6.1.7 Isolation Requirements of above TRM, when
reprogramming MUXMODE, DELAYMODE, and MODESELECT fields, there is a
potential for a significant glitch on the corresponding IO. It is hence
recommended to do this with I/O isolation (which can only be done in
initial stages of bootloader). QSPI is one such module that requires
IODELAY configuration. So, this patch removes the pinmux for
QSPI for DRA74/DRA72 EVM as it needs to be done in bootloader (U-Boot)
and cannot be done in kernel.

Users should migrate to U-Boot v2016.05-rc1 or higher.

As per the data sheet starting from SPRUHQ0H (Nov 2015 - Latest[1]),
VDD_CORE can vary from 0.85v to 1.15v for AVS class0. VDD GPU/DSP
et.al. can range from 0.85v to 1.25V with AVS class0

Since dynamic voltage scaling is disabled for DRA7/AM57xx SoCs for
all SoC rails other than MPU, the bootloader is responsible for
setting up the AVS class0 voltage, however, with wrong voltage machine
constraints in dtb, regulator framework will lower the voltage below
the required voltage levels for certain samples in production flow.
This can cause catastrophic failures which can be pretty hard to
identify.

Update board files which don't match required specification.

DRA72-EVM now has an upgrade to Rev C with SR2.0 silicon. As part of
this change, a few updates were factored in that were software
incompatible with previous board in few areas:
- We now use DP83867 ethernet phy instead of older DP838865 which fails
  in certain use cases.
- Two Ethernet ports now instead of the single one in rev B.
- polarities changed for certain pcf gpios
- Due to SoC phy current requirements, VDDA supplies are split between
 ldo3 and ldo2 (ldo2 was previously unused). NOTE: DSS (VDDA_VIDEO) is
 still supplied by ldo5, HDMI is now supplied by LDO2 instead of using
 LDO3.

NOTE: It does not make much sense to spin off a new board compatible
flag since there is no real benefit for the same.

ChiliSOM has TPS65217's PWR_EN pin connected to AM335x PMIC_POWER_EN
pin. Processor's PMIC_POWER_EN is controlled by it's internal RTC, hence

The binding definition for the PCF857x GPIO expanders doesn't mention
a "ti,pcf8575" compatible string.  This is apparently because TI is
only a second source - there is no functional difference between
PCF8575 chips manufactured by TI and NXP, and the same board might be
populated with either depending on availability.

This is not a problem in practice because the I2C core uses
of_modalias_node() before matching drivers and this strips the
manufacturer name.
