By default, only the later has battery backup, the former does not. The order in which the RTCs are probed on boot is random, which means the kernel might pick up system time from the STM32 RTC which has no battery backup. This then leads to incorrect initial system time setup, even though the HW RTC has correct time configured in it. Add DT alias entries, so that the RTCs get assigned fixed IDs and the HW RTC is always picked by the kernel as the default RTC, thus resulting in correct system time in early userspace.

There are multiple accounts of this in the SMSC PHY driver patches which attempted to make EDPD reliable, however it seems there is always some sort of corner case left. Unfortunatelly, there is no errata documented which would confirm this to be a silicon bug on the LAN87xx series of PHYs (LAN8700, LAN8710, LAN8720 at least). Disable EDPD on the DHCOM SoM, just like multiple other boards already do as well, to make the cable detection reliable.

To make this more convoluted, the same EXTI input (not the same GPIO line) is shared between Button B which is Active-Low IRQ, and touchscreen IRQ which is Edge-Falling IRQ, which cannot be used at the same time. In case the LCD board with touchscreen is in use, which is the case here, LED0 must be disabled, Button B must be polled, so the touchscreen interrupt works as it should. Update the touchscreen IRQ line assignment, disable LED0 and use polled GPIO button driver for Button B, since the DT here describes baseboard with LCD board.
