From: Sebastian Reichel <redacted> [ Upstream commit cd7cd5b716d594e27a933c12f026d4f2426d7bf4 ] PPD has only one ACHC device, which effectively is a Kinetis microcontroller. It has one SPI interface used for normal communication. Additionally it's possible to flash the device firmware using NXP's EzPort protocol by correctly driving a second chip select pin and the device reset pin.
