- * The signal type is GPIO if the signal name has "GPI" as a prefix.
- * strncmp (rather than strcmp) is used to implement the prefix
- * requirement.
+ * We need to differentiate between GPIO and non-GPIO signals to
+ * implement the gpio_request_enable() interface. For better or worse
+ * the ASPEED pinctrl driver uses the expression names to determine
+ * whether an expression will mux a pin for GPIO.
*
- * expr->signal might look like "GPIOB1" in the GPIO case.
- * expr->signal might look like "GPIT0" in the GPI case.
+ * Generally we have the following - A GPIO such as B1 has:
+ *
+ * - expr->signal set to "GPIOB1"
+ * - expr->function set to "GPIOB1"
+ *
+ * Using this fact we can determine whether the provided expression is
+ * a GPIO expression by testing the signal name for the string prefix
+ * "GPIO".
+ *
+ * However, some GPIOs are input-only, and the ASPEED datasheets name
+ * them differently. An input-only GPIO such as T0 has:
+ *
+ * - expr->signal set to "GPIT0"
+ * - expr->function set to "GPIT0"
+ *
+ * It's tempting to generalise the prefix test from "GPIO" to "GPI" to
+ * account for both GPIOs and GPIs, but in doing so we run aground on
+ * another feature:
+ *
+ * Some pins in the ASPEED BMC SoCs have a "pass-through" GPIO
+ * function where the input state of one pin is replicated as the
+ * output state of another (as if they were shorted together - a mux
+ * configuration that is typically enabled by hardware strapping).
+ * This feature allows the BMC to pass e.g. power button state through
+ * to the host while the BMC is yet to boot, but take control of the
+ * button state once the BMC has booted by muxing each pin as a
+ * separate, pin-specific GPIO.
+ *
+ * Conceptually this pass-through mode is a form of GPIO and is named
+ * as such in the datasheets, e.g. "GPID0". This naming similarity
+ * trips us up with the simple GPI-prefixed-signal-name scheme
+ * discussed above, as the pass-through configuration is not what we
+ * want when muxing a pin as GPIO for the GPIO subsystem.
+ *
+ * On e.g. the AST2400, a pass-through function "GPID0" is grouped on
+ * balls A18 and D16, where we have:
+ *
+ * For ball A18:
+ * - expr->signal set to "GPID0IN"
+ * - expr->function set to "GPID0"
+ *
+ * For ball D16:
+ * - expr->signal set to "GPID0OUT"
+ * - expr->function set to "GPID0"
+ *
+ * By contrast, the pin-specific GPIO expressions for the same pins are
+ * as follows:
+ *
+ * For ball A18:
+ * - expr->signal looks like "GPIOD0"
+ * - expr->function looks like "GPIOD0"
+ *
+ * For ball D16:
+ * - expr->signal looks like "GPIOD1"
+ * - expr->function looks like "GPIOD1"
+ *
+ * Testing both the signal _and_ function names gives us the means
+ * differentiate the pass-through GPIO pinmux configuration from the
+ * pin-specific configuration that the GPIO subsystem is after: An
+ * expression is a pin-specific (non-pass-through) GPIO configuration
+ * if the signal prefix is "GPI" and the signal name matches the
+ * function name.
