and move the nodes and properties included by it directly
to keep the dtb same.

The memory node has been changed to get rid of warnings
(see below). It contains the memory base address as that is
fixed for DA850 SoCs. But the size needs to be added by
bootloader or a board specific dts.

This makes use of the gpio-ranges feature that connects GPIO
controllers and PINMUX controllers.

In da850.dtsi, pinctrl-single,gpio-range is added to the pinmux node
and gpio-ranges is added to the GPIO node. Unfortunately, the way the
pinctrl-single driver enumerates the pins (starting with LSB) causes
them to be in reverse order compared to the way the gpios are assigned.
As a result, we have to declare the mapping for each GPIO individually.

This also lets us remove all of the GPIO pinmuxes from
da850-lego-ev3.dts. (Other da850 boards do not currently have any
GPIO pinmuxes declared.)

The TI Davinci DA8xx family of SoCs have a single DSP subsystem
that is comprised of TI's standard TMS320C674x megamodule and
several blocks of internal memory (L1P, L1D and L2 RAMs). Add
the DT node for this DSP processor sub-system. The processor
does not have an MMU, and uses a chip-level signalling register
and shared memory for inter-processor communication with the
ARM core.

The node has been added in disabled state, and can be enabled
in the respective board dts file with an associated reserved
memory block.

TI DA8xx/OMAPL13x/AM17xx/AM18xx SoCs have extra UART registers beyond

indicate this. Also, at least one of these registers uses the full 32

For some devices, the PWMSS is a parent of eCAP and ePWM and provides
the functional clocks for those submodules. The ti,am33xx-ecap and
ti,am33xx-ehrpwm bindings were based on this parent child relationship
where the functional clock would be grabbed from the module's parent.

However, DA850 doesn't have a PWMSS and the eCAP and ePWM provides
their functional clock themselves. Therefore, prefer the new binding
that doesn't assume this parent child relationship.

Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3.
With the new bindings boards can customize and tweak the DMA channel
priority to match their needs. With the new binding the memcpy is safe
to be used since with the old binding it was not possible for a driver
to know which channel is allowed to be used as non HW triggered channel.
Using the new binding will allow us to reserve PaRAM slots to be used by
the DSP which was not possible before and prevented the da850 boards to be
moved to DT only.

Note that the DMA memcpy is disabled, it can be enabled by reserving
channels for memcpy by adding the following property to the edma node:
ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */
