drivers/i2c: Add driver for rt5663 codec
This commit adds a new driver for the RT5663 codec to use instead of the generic i2c driver. Since the kernel needs additional driver-specific device properties we need a BIOS driver that can provide those properties. The kernel driver devicetree properties for this codec are at: linux/Documentation/devicetree/bindings/sound/rt5663.txt This was tested by booting and verifying the generated SSDT contains the expected device properties in _DSD. Scope (\_SB.PCI0.I2C4) { Device (RT53) { Name (_HID, "10EC5663") Name (_UID, Zero) Name (_DDN, "Realtek RT5663 Codec") Method (_STA, 0, NotSerialized) { Return (0x0F) } Name (_CRS, ResourceTemplate () { I2cSerialBus (0x0013, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\_SB.PCI0.I2C4", 0x00, ResourceConsumer) GpioInt (Edge, ActiveBoth, Exclusive, PullDefault, 0x0000, "\\_SB.PCI0.GPIO", 0x00, ResourceConsumer) { 0x0051 } }) Name (_DSD, Package (0x02) { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") Package (0x05) { Package (0x02) { "irq-gpios", Package (0x04) { \_SB.PCI0.I2C4.RT53, Zero, Zero, Zero } }, Package (0x02) { "realtek,dc_offset_l_manual", 0x00FFD160 }, Package (0x02) { "realtek,dc_offset_r_manual", 0x00FFD1C0 }, Package (0x02) { "realtek,dc_offset_l_manual_mic", 0x00FF8A10 }, Package (0x02) { "realtek,dc_offset_r_manual_mic", 0x00FF8AB0 } } }) } } Change-Id: I3425fcbe13c9a5987fc91086d283a86db55c0819 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/20904 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
