Implements the USB part of Intel USB-I2C/GPIO/SPI adapter device named "La Jolla Cove Adapter" (LJCA). The communication between the various LJCA module drivers and the hardware will be muxed/demuxed by this driver. Three modules ( I2C, GPIO, and SPI) are supported currently. Each sub-module of LJCA device is identified by type field within the LJCA message header. The sub-modules of LJCA can use ljca_transfer() to issue a transfer between host and hardware. And ljca_register_event_cb is exported to LJCA sub-module drivers for hardware event subscription. The minimum code in ASL that covers this board is Scope (\_SB.PCI0.DWC3.RHUB.HS01) { Device (GPIO) { Name (_ADR, Zero) Name (_STA, 0x0F) } Device (I2C) { Name (_ADR, One) Name (_STA, 0x0F) } Device (SPI) { Name (_ADR, 0x02) Name (_STA, 0x0F) } } Signed-off-by: Wentong Wu <wentong.wu@xxxxxxxxx> Reviewed-by: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx> Reviewed-by: Andi Shyti <andi.shyti@xxxxxxxxxxxxxxx> Tested-by: Hans de Goede <hdegoede@xxxxxxxxxx>
