[ Upstream commit e17e7c498d ]
On am57xx-beagle-x15, 5V0 is connected to P16, P17, P18 and P19
connectors. On am57xx-evm, 5V0 regulator is used to get 3V6 regulator
which is connected to the COMQ port. Model 5V0 regulator here in order
for it to be used in am57xx-evm to model 3V6 regulator.

The ti,no-idle-on-init and ti,no-reset-on-init flags need to be at
the interconnect target module level for the modules that have it
defined. Otherwise we get the following warnings:
dts flag should be at module level for ti,no-idle-on-init
dts flag should be at module level for ti,no-reset-on-init

If UHS speed modes are enabled, a compatible SD card switches down to
1.8V during enumeration. If after this a software reboot/crash takes
place and on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.
The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the
card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and
am57xx-evms don't have this capability, disable voltage switching for
these boards.
The major effect of this is that the maximum supported speed
mode is now high speed(50 MHz) down from SDR104(200 MHz).
commit 88a748419b ("ARM: dts: am57xx-idk: Remove support for voltage
switching for SD card") did this only for idk boards. Do it for all
affected boards.

The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

According to errata i880 description the speed of Ethernet port 1 on AM572x
SoCs rev 1.1 should be limited to 10/100Mbps, because RGMII2 Switching
Characteristics are not compatible with 1000 Mbps operation [1].
The issue is fixed with Rev 2.0 silicon.
Hence, rework Beagle-X15 and Begale-X15-revb1 to use phy-handle instead of
phy_id and apply corresponding limitation to the Ethernet Phy 1.

Commit d20f997b4d ("ARM: dts: am57xx-beagle-x15: Remove pinmux
configurations for erratum i869") fat fingered a change in which
basically replaced mmc2_pinctrl_default with mmc1_pinctrl_default. And
kernel dutifully reports conflict of usage.
[...]
pinctrl-single 4a003400.pinmux: pin 4a00376c.0 already requested by
4809c000.mmc; cannot claim for 480b4000.mmc
pinctrl-single 4a003400.pinmux: pin-219 (480b4000.mmc) status -22
pinctrl-single 4a003400.pinmux: could not request pin 219 (4a00376c.0)
from group mmc1_pins_default on device pinctrl-single
omap_hsmmc 480b4000.mmc: Error applying setting, reverse things back
omap_hsmmc 480b4000.mmc: could not initialize pin control state
[...]
But, thanks to the fact that we were in fact setting all the muxes in
U-Boot, all the MMC devices were still properly detected.
Fix the typo.

Latest update to the BeagleBoard-X15 platform (revision B1)[1] updates
for allowing UHS SD cards to function with the split of supply to SD
card from a dedicated LDO.
As a result of this, AM57xx BeagleBoard-X15 now uses gpio2_30 instead
of gpio6_28 for HDMI because HDMI_LS_OE should now be switched from
GPIO6_28(Y9) to GPIO2_30 (AG8) to avoid a 1.8V GPIO toggling a 3.3V
SoC input when the SD card is in UHS 1.8V mode.
NOTE: For UHS mode to function, we need full fledged IODelay support
in kernel to be functional. IODelay support is yet to be added.
Further, It does not make much sense to spin off a new board
compatible flag since there is no real functional benefit for the
same.
Note: Even though production version is supposed to be B1, there is
over ~200 boards of previous version (A2)[2] out there which continue
to get supported with the existing dts file (to maintain compatibility
with existing bootloaders for A2) and the production board is now
supported as revb1.
