   4 Subject: [PATCH] dm: adc: Add SPL_ADC Kconfig symbol for use of ADC in SPL
   5
   6 What model of Radxa ZERO 3W/3E board can be identified using ADC at
   7 runtime, add a Kconfig symbol to allow use of ADC in SPL.
   8
   9 This will be used to identify board model in SPL to allow loading
  10 correct FIT configuration and FDT for U-Boot proper at SPL phase.
