> From: Peng Fan <peng.fan at nxp.com>
> Add a static u-boot config for i.MX93 low drive mode support. When
> low drive mode is enabled, VDD_SOC is set to 0.75V. Bus clocks,
> A55 core clock (900Mhz), DDR clock (1866MTS), and some peripherals
> clocks (USDHC/FLEXSPI/PDM/DISP_PIX/CAM_PIX) must decrease to meet
> max frequencies in low drive mode.
> Also set standby voltage for buck1
