Documentation: ACPI: move i2c-muxes.txt to firmware-guide/acpi and convert to reST
This converts the plain text documentation to reStructuredText format and adds it to Sphinx TOC tree. No essential content change.

-ACPI I2C Muxes
---------------
-
-Describing an I2C device hierarchy that includes I2C muxes requires an ACPI
-Device () scope per mux channel.
-
-Consider this topology:
-
-+------+ +------+
-| SMB1 |-->| MUX0 |--CH00--> i2c client A (0x50)
-| | | 0x70 |--CH01--> i2c client B (0x50)
-+------+ +------+
-
-which corresponds to the following ASL:
-
-Device (SMB1)
-{
- Name (_HID, ...)
- Device (MUX0)
- {
- Name (_HID, ...)
- Name (_CRS, ResourceTemplate () {
- I2cSerialBus (0x70, ControllerInitiated, I2C_SPEED,
- AddressingMode7Bit, "^SMB1", 0x00,
- ResourceConsumer,,)
- }
-
- Device (CH00)
- {
- Name (_ADR, 0)
-
- Device (CLIA)
- {
- Name (_HID, ...)
- Name (_CRS, ResourceTemplate () {
- I2cSerialBus (0x50, ControllerInitiated, I2C_SPEED,
- AddressingMode7Bit, "^CH00", 0x00,
- ResourceConsumer,,)
- }
- }
- }
-
- Device (CH01)
- {
- Name (_ADR, 1)
-
- Device (CLIB)
- {
- Name (_HID, ...)
- Name (_CRS, ResourceTemplate () {
- I2cSerialBus (0x50, ControllerInitiated, I2C_SPEED,
- AddressingMode7Bit, "^CH01", 0x00,
- ResourceConsumer,,)
- }
- }
- }
- }
