[edk2] [platforms: PATCH 10/12] Marvell/Drivers: MvPca95xxDxe: Introduce I2C GPIO driver

2018-10-19 Thread Marcin Wojtas
Marvell Armada 7k/8k-based platforms may use Pca95xx to extend amount of the GPIO pins. This patch introduces support for PCA95xxx I2C IO expander family, which is a producer of MARVELL_GPIO_PROTOCOL, by implementing necessary routines. Driver is based on initial work done by Allen Yan .
