[PATCH v5 00/14] Initial Microchip PIC32MZDA Support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series adds support for the Microchip PIC32MZDA MIPS platform.
All drivers required to boot from a MMC uSD card are included. Clock,
external interrupt controller, serial, SDHCI, and pinctrl/gpio drivers
are included. This has been tested on a PIC32MZDA Starter Kit. A tree
with these changes is available at [0].
