SeeedStudio BeagleBone Green (BBG) is clone of the BeagleBone Black (BBB) minus
the HDMI port and addition of two Grove connectors (i2c2 and usart2).

This board can be identified by the 1A value after A335BNLT (BBB) in the at24 eeprom:
1A: [aa 55 33 ee 41 33 33 35  42 4e 4c 54 1a 00 00 00 |.U3.A335BNLT....|]

Add the sub-mailbox nodes that are used to communicate between
MPU and the remote processors IPU1, IPU2 and DSP1. These match the
respective node definitions on DRA74x to maintain compatibility for
the equivalent remote processors. There is no DSP2 on DRA72x, and
so the corresponding sub-mailbox node is not added.

These sub-mailbox nodes are added to match the hard-coded mailbox
configuration used within the TI IPC 3.x software package. The
Dual-Cortex M4 IPU1 and IPU2 processor sub-systems are assumed to
be running in SMP-mode, and hence only a single sub-mailbox node
is added for each.

All these sub-mailbox nodes are left in disabled state, and should
be enabled (and modified if needed) as per the individual product
configuration in the corresponding board dts files.

from being a child node of ocp to be the child node of
'syscon'. Since 'syscon' doesn't have the 'ranges' property,
address translation fails while trying to convert the address
to resource. Fix it here by populating 'ranges' property in

Originally, all the SoC PHY rails were supplied by LDO3. However, as a
result of characterization, it was determined that this posed a risk in
extreme load  conditions. Hence the PHY rails are split between two
different LDOs. Update the related node as a result

LDO3/VDDA_1V8_PHYA supplies vdda_usb1, vdda_usb2, vdda_sata, vdda_usb3
LDO4/VDDA_1V8_PHYB supplies vdda_pcie1, vdda_pcie0, vdda_hdmi, vdda_pcie

NOTE: We break compatibility with pre-production boards with this change
since, the PMIC LDO4 is disabled at OTP level.

The new configuration is the plan of record and all pre-production
boards are supposed to be replaced with the latest boards matching the
mentioned configuration.

Some very few 10 something boards have been created and
stopped production till the latest modifications were done (PMIC USB
interrupt, LDO4 etc) - and all of those boards are now getting
scrapped.. If there are any (as per tracking information, there should
not be any), TI should be contacted to have them replaced.

Looks like I made a typo on the control base, all the 81xx
SoCs have it at 0x48140000 base. We've just gotten away with
the typo as the Ethernet phy was configured by the bootloader
on my test system and we're not yet using the pinctrl.

In addition to fixing the contol base, we need to also use the
right Ethernet phy flags to initialize it. And we are still
missing the PLL driver for dm814x and only relying on the
divider and mux clocks.

Let's fix pinmux address of gpio 170 used by tfp410 powerdown-gpio.

According to the OMAP35x Technical Reference Manual

the pinmux address of gpio 170 must be 0x480021C6.
