Currently only 2 drivers are supported, but it would be trivial to support all 4 combinations.
Define these arrays listing all the LEDs in your `<keyboard>.c`:
- const is31_led g_is31_leds[DRIVER_LED_TOTAL] = {
- /* Refer to IS31 manual for these locations
- * driver
- * | LED address

- {0, C3_3},

+ * driver
+ * | LED address
+ * | | */
+ { 0, C1_1 },
+ { 0, C1_15 },
+ // ...
+ }
