Hello, I am trying to poke around and understand how to add support for a new lure.
I saw the thread 'Adding an SPI device to the Minnowboard' from late 2013 and 'SPI support on minnowboard v1' from Aug 2014. Darren Hart notes: Ultimately we want to do things like this without board files by using the _DSD mechanisms introduced by the ACPI 5.1 specification last week I just wanted to confirm the ACPI mechanism is not the recommended way yet, and that using low-speed-spidev.c as a template is still the way to go. Additional q: How do you tell the SPI controller that you have an active-high instead of the usual active-low device? Is it correct to do a bitwise or with SPI_CS_HIGH (0x4) with your SPI_MODE in your spi_board_info struct, like: .mode = SPI_MODE_0 | SPI_CS_HIGH
