The patch adds the following interfaces according the SMARC Spec 1.1
[1] and provided schematics:
- SMARC SPI0/1
Note: Since Kontron still uses silicon revisions below 1.3 they have
add a spi-nor to implement Workaround #1 of erratum ERR006282.
- SMARC SDIO
- SMARC LCD
- SMARC HDMI
- SMARC Management pins
Note: Kontron don't route all of these pins to the i.MX6, some are
routed to the SoM CPLD.
- SMARC GPIO
- SMARC CSI Camera
Note: As specified in [1] the data lanes are shared to cover the
csi and the parallel case. The case depends on the baseboard so
muxing the data lanes is not part of this patch.
- SMARC I2S
- SMARC Watchdog
Note: The watchdog output pin is routed to the CPLD and the SMARC
header. The CPLD performs a reset after a 30s timeout so we
need to enable the watchdog per default.
- SMARC module eeprom
Due to the lack of hardware not all of these interfaces are tesetd.
