-    * 1× MIIM mode (virtual MIIM, MDC: GPIO2, MDIO: GPIO3)
+    * 1× MIIM mode (virtual MIIM, address 31)
     * 2× Shift register mode (LED_CLK, LED_DAT)
   * Winbond W631GU8MB (128MiB DDR3 SDRAM)
   * Macronix MX25L25635F, Winbond 25Q256FVFG (32MiB SPI flash)
   * Sipex SP3232, ADM3202 RS-232 transceiver
+=== GPIO ===
+  * Internal GPIO:
+    * gpio1: active low, SoC reset
+    * gpio2: MDC line to RTL8231
+    * gpio3: MDIO line to RTL8231
+  * RTL8231 @ phy address 31:
+    * gpio0-4: device ID
+    * gpio5-6: device hardware revision
+    * gpio27: reset button
+    * gpio16: watchdog state (active low)
+    * gpio34: (unknown, maybe watchdog related, initialised to 1)
+    * gpio9: watchdog feed (10s)
+    * gpio24: SFP25 "OE" (MOD_DEF0?, used to detect module)
+    * gpio11: SFP25 loss of signal (used to detect media change)/
+    * gpio17: SFP25 transmit disable
+    * gpio28: SFP26 "OE" (MOD_DEF0?)
+    * gpio12: SFP26 loss of signal
+    * gpio18: SFP26 transmit disable
+    * gpio15: SCK for SFP25, SFP26, TERM1, TERM2, FAN1, FAN2 (shared I2C clock)
+    * SDA lines:
+      * gpio13: SFP25
+      * gpio14: SFP26

+      * gpio31: FAN1 (26P only)
+      * gpio33: FAN2 (26P only)
+=== LED ===
+All LEDs are controlled by the port LED peripheral:
+  * Ports 1-24: Green Link/Act LED (idx 0), amber PoE LED (idx 1) (26P only)
+  * Ports 25-26: Green Link/Act LED (idx 0), green gigabit LED (idx 1)
+  * Green status LED: user controlled LED for port 27, index 1
+  * Amber status LED: user controlled LED for port 28, index 1
+The green and amber device status LEDs are wired in anti-parallel, and only one can be enabled at a time.
+=== Environment ===
+Present only on the SG220-26P.
+  * FAN1: TC655 at 0x1B. Does not appear to be present on SG220-26P.
+  * FAN2: TC655 at 0x1B. The TC655 controls both fans behind the PSU of the SG220-26P.
+  * TEMP1: LM75A at 0x49
+  * TEMP2: LM75A at 0x4B
