+title: nuvoton NPCM7XX I2C Controller Device Tree Bindings
+
+description: |
+  The NPCM750x includes sixteen I2C bus controllers. All Controllers support
+  both master and slave mode. Each controller can switch between master and slave
+  at run time (i.e. IPMB mode). Each controller has two 16 byte HW FIFO for TX and
+  RX.
