2023-10-04	mb/google/geralt: Update voltage mapping tables for RAM ID and LCMD ID	Yidi Lin
	The tolerance of ADC voltage table is too small. Update the table values accordring to the suggestion from the hardware team. The patch is prepared for the derived projects. There is no actual issue now.

2023-03-24	mb/google/geralt: Read LCM ID from ADC channels 4 and 5	Yidi Lin
	The SKU ID is not really used on Geralt. Both ADC channels 4 and 5 will be used for LCM ID on derived projects. For Geralt reference board, only PANEL_ID_LOW_CHANNEL is valid. BRANCH=none BUG=b:247415660 TEST=boot Geralt proto0 and see FW screen in DEV mode.

2022-08-03	mb/google/geralt: Implement SKU ID and RAM code	Rex-BC Chen
	- Retrieve the SKU ID for Geralt via CBI interface. If that failed (or no data found), fall back to ADC channels for SKU ID. - The RAM code is implemented by the resistor straps that we can read and decode from ADC.
