+Subject: [PATCH] MIPS: octeon: Add interface mode detection for Octeon II
+
+Add interface mode detection for Octeon II. This is necessary to detect
+the interface modes correctly on the UBNT E200 board. Code is taken
+from the UBNT GPL source release, with some alterations: SRIO, ILK and
+RXAUI interface modes are removed and instead return disabled as these
+modes are not currently supported.

+Subject: [PATCH] MIPS: Octeon: Add twsi interrupt initialization for OCTEON
+ 3XXX, 5XXX, 63XX
+
+In octeon_3xxx.dts file, there is a definiton for twsi/twsi2 interrupts.
+But there is no code for initialization of this interrupts. This patch adds
+code for initialization of twsi interrupts.
