Updating a DRM driver for ILI9488 Driver Chip based TFT displays, so that it works for the UDOO Bolt. Have an ACPI SSDT that I've written. I see from acpidump & acpixtract that there exists a DSDT and multiple SSDT's. The only issue I'm having is that I'm not certain what named object is associated with the Bolt's EC SPI Controller. Also, are there any known examples of DSDT/SSDT that define how to use SPI or I2C slave devices and work on the bolt? I haven't run into anything yet. Can find project here for those curious. https://github.com/under-view/spi-tft-ILI9488 The closest named object + path I found for SPI controller is Code: \_SB.PCI0.S900._Y15._BAS
Have you checked the EAPI yet? Maybe has what you looking for. https://www.udoo.org/docs-bolt/BIOS_UEFI_and_Tools/EAPI.html
