 /*
  * ADI slave devices include RTC, ADC, regulator, charger, thermal and so on.
- * The slave devices address offset is always 0x8000 and size is 4K.
+ * ADI supports 12/14bit address for r2p0, and additional 17bit for r3p0 or
+ * later versions. Since bit[1:0] are zero, so the spec describe them as
+ * 10/12/15bit address mode.
+ * The 10bit mode supports sigle slave, 12/15bit mode supports 3 slave, the
+ * high two bits is slave_id.
+ * The slave devices address offset is 0x8000 for 10/12bit address mode,
+ * and 0x20000 for 15bit mode.
