LDO2 is expansion connector supply on STM32MP13xx DHCOR DHSBC rev.200. LDO5 is carrier board supply on STM32MP13xx DHCOR DHSBC rev.200. Keep both regulators always enabled to make sure both the carrier board and the expansion connector is always powered on and supplied with correct voltage. Describe ST33TPHF2XSPI TPM 2.0 chip reset lines. This is a port of Linux kernel patch posted at: https://patchwork.kernel.org/project/linux-arm-kernel/patch/20250302152605.54792-1-marex@denx.de/ This change shall be removed when the Linux kernel DT change lands and Linux kernel DTs get synchronized with U-Boot DTs.
