ARM: Add GXP I2C Support
|
expand
|
From: Nick Hawkins <nick.hawkins@hpe.com> The GXP SoC supports 10 I2C engines. Each I2C engine is completely independent and can function both as an I2C master and I2C slave. The I2C master can operate in a multi master environment. The engines support a scalable speed from 8kHZ to 1.5 Mhz.
