Pinmuxing for DRA7x/AM57x family of processors need to be done in IO
isolation as part of initial bootloader executed from SRAM. This is
done as part of iodelay configuration sequence and is required due
to the limitations introduced by erratum ID: i869[1] (IO Glitches
can occur when changing IO settings) and elaborated in the Technical
Reference Manual[2] 18.4.6.1.7 Isolation Requirements.
Only peripheral that is permitted for dynamic pin mux configuration
is MMC and DCAN. MMC is permitted to change to accommodate the
requirements for varied speeds (which require IO-delay support in
kernel as well). DCAN is a result of i893[1] (DCAN initialization
sequence). With the exception of DCAN and MMC, all other pin mux
configurations are removed from the dts.

dra72-evm-common.dtsi consolidates dra72-evm.dts and dra72-evm-revc.dts
which also include tps65917 pmic support as both the evms uses the same
pmic. But, dra71-evm has mostly similar features with a different pmic.
In order to exploit dra72-evm-common.dtsi, creating a separate dtsi
for tps65915 support and including it in respective board files.

In order to have a proper topology of regulators for a platform, each
registering regulator needs to populate supply_name field for identifying
its supply's name. Add supply_name field for lp873x regulators.

Are dra72 and dra7 really useful? Your list is a bit long. Perhaps it is

RTC is not available on DRA71x, so accessing any of the RTC
register or clkctrl register will lead to a crash. So, do not
register RTC hwmod for DRA71x.

The DRA718-evm is a board based on TI's DRA718 processor targeting
BOM-optimized entry infotainment systems and is a reduced pin and
software compatible derivative of the DRA72 ES2.0 processor.
This platform features:
- 2GB of DDR3L
- Dual 1Gbps Ethernet
- HDMI,
- uSD
- 8GB eMMC
- CAN
- PCIe
- USB3.0
- Video Input Port
- LP873x PMIC
More information can be found here[1].
Adding support for this board while reusing the data available in
dra72-evm-common.dtsi.
