[PATCH 2/6] MIPS: mobileye: eyeq5: add 5 I2C controller nodes
Posted by Théo Lebrun 5 months, 1 week ago 
Add the SoC I2C controller nodes to the platform devicetree. Use a
default bus frequency of 400kHz. They are AMBA devices that are matched
on PeriphID.

Set transfer timeout to 10ms instead of Linux's default of 200ms.
