+Subject: [PATCH] realtek: Add support for RTL9300/RTL9310 I2C multiplexing
+
+The RTL9300/RTL9310 I2C controllers have support for 2 independent I2C
+masters, each with a fixed SCL pin, that cannot be changed. Each of these
+masters can use 8 (RTL9300) or 16 (RTL9310) different pins for SDA.
+This multiplexer directly controls the two masters and their shared
+IO configuration registers to allow multiplexing between any of these
+busses. The two masters cannot be used in parallel as the multiplex
+is protected by a standard multiplex lock.
+
