TI DA8xx/OMAPL13x/AM17xx/AM18xx SoCs have extra UART registers beyond
the standard 8250 registers, so we need a new compatible string to
indicate this. Also, at least one of these registers uses the full 32
bits, so we need to specify reg-io-width in addition to reg-shift.
"ns16550a" is left in the compatible specification since it does work
as long as the bootloader configures the SoC UART power management
registers.

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 */
