* DOC: Overview
*
* gmux is a microcontroller built into the MacBook Pro to support dual GPUs:
- * A `Lattice XP2`_ on pre-retinas, a `Renesas R4F2113`_ on retinas.
+ * A `Lattice XP2`_ on pre-retinas, a `Renesas R4F2113`_ on pre-T2 retinas.
+ *
+ * On T2 Macbooks, the gmux is part of the T2 Coprocessor's SMC. The SMC has
+ * an I2C connection to a `NXP PCAL6524` GPIO expander, which enables/disables
+ * the voltage regulators of the discrete GPU, drives the display panel power,
+ * and has a GPIO to switch the eDP mux. The Intel CPU can interact with
+ * gmux through MMIO, similar to how the main SMC interface is controlled.
*
* (The MacPro6,1 2013 also has a gmux, however it is unclear why since it has
* dual GPUs but no built-in display.)
*
* gmux is connected to the LPC bus of the southbridge. Its I/O ports are
* accessed differently depending on the microcontroller: Driver functions
- * to access a pre-retina gmux are infixed ``_pio_``, those for a retina gmux
- * are infixed ``_index_``.
+ * to access a pre-retina gmux are infixed ``_pio_``, those for a pre-T2
+ * retina gmux are infixed ``_index_``, and those on T2 Macs are infixed
+ * with ``_mmio_``.

+ * to trigger an ACPI GPE. ACPI name GMGP holds this GPIO pin's number. On the
+ * MBP5 2008/09 it's GPIO pin 22 of the Nvidia MCP79, on following generations
+ * it's GPIO pin 6 of the Intel PCH, on MMIO gmux's it's pin 21.
+ *
* The GPE merely signals that an interrupt occurred, the actual type of event
* is identified by reading a gmux register.
+ *
+ * In addition to the GMGP name, gmux's ACPI device also has two methods GMSP
+ * and GMLV. GMLV likely means "GMUX Level", and reads the value of the GPIO,
+ * while GMSP likely means "GMUX Set Polarity", and seems to write to the GPIO's
+ * value. On newer Macbooks (This was introduced with or sometime before the
+ * MacBookPro14,3), the ACPI GPE method differentiates between the OS type: On
+ * Darwin, only a notification is signaled, whereas on other OSes, the GPIO's
+ * value is read and then inverted.
+ *
+ * Because Linux masquerades as Darwin, it ends up in the notification-only code
+ * path. On MMIO gmux's, this seems to lead to us being unable to clear interrupts,
+ * unless we call GMSP(0). Without this, there is a flood of status=0 interrupts
+ * that can't be cleared. This issue seems to be unique to MMIO gmux's.

- * driver to write the non-standard DSI reg 0x9f with the desired backlight
- * level to set the duty-cycle of the LCD's PWM output.
- *
- * To avoid having to have a similar hack in the mainline kernel the LP8557

+ X86 tablets which ship with Android as (part of) the factory image
+ typically have various problems with their DSDTs. The factory kernels
+ shipped on these devices typically have device addresses and GPIOs
+ hardcoded in the kernel, rather than specified in their DSDT.
+
+ With the DSDT containing a random collection of devices which may or
+ may not actually be present. This driver contains various fixes for
+ such tablets, including instantiating kernel devices for devices which
+ are missing from the DSDT.
+
+ If you have a x86 Android tablet say Y or M here, for a generic x86
+ distro config say M here.
