However, the correct configuration for the SD/OE pin cannot be determined automatically. Therefore, add the appropriate properties to configure this pin. I have CC'd some people who appear to have access to the following boards which use the versaclock5: - Salvator-X - HiHope RZ/G2[MN] Main Board - Beacon Embedded Works RZ/G2N Development Kit as I could not find schematics for these boards. You can help me out by (pick one): - Run the following command and send me the output: $ grep 10: /sys/kernel/debug/regmap/*-006a/registers - Measure the voltage on the SD/OE pin on a functioning board. - Inspect (or send me) the schematic to determine the state of the SD/OE pin during normal operation. My suspicion is that all of these boards use the same configuration (SD/OE pin tied high) owing to their common design heritage. Thanks in advance.
