plat-stm32mp1: syscfg: HLSV mode for IO domains
Add platform API functions stm32mp_set_hslv_state() and
stm32mp_enable_fixed_vdd_hslv() to configure High Speed Low Voltage
mode of IO domains.
Platform function stm32mp_enable_fixed_vdd_hslv() is designed for
fixed voltage IO domains that need to be enable at boot time only
since the supply voltage level never changes.
On STM32MP13 variants, SDMMC IO domains may not be supplied by fixed
voltage VDD but rather by a supply which voltage level can change
at runtime for example to support SD/MMC normative 1.8V and 3.3V voltage
modes. Therefore these IO domains require a runtime configuration
function implemented by stm32mp_set_hslv_state().

plat-stm32mp1: syscfg: STM32MP13 dynamic IO compensation

plat-stm32mp1: syscfg: STM32MP13 dynamic IO compensation
Replace IO compensation API functions
stm32mp_syscfg_enable_io_compensation() and
stm32mp_syscfg_disable_io_compensation() with a new API function
stm32mp_set_io_comp_by_index() dedicated to runtime configuration
of STM32MP13 SDMMC's domains IO compensation only.
On STM32MP15 variant, the configuration is enabled only during
initialization. On STM32MP13 variant, the same feature is also enabled
during initialization but the device embeds 2 more IO domains
(SDMMC1 and SDMMC2) for which the new API function allow runtime
reconfiguration support.
For sake of simplicity, keep related clocks always on.
