All drivers required to boot from a MMC uSD card are included. Clock, external interrupt controller, serial, SDHCI, and pinctrl drivers are included. This has been tested on a PIC32MZDA Starter Kit. A tree with these changes is available at [0]. [0] https://github.com/joshua-henderson/linux/tree/pic32-upstream-v2 Changes since v1 (https://lkml.org/lkml/2015/11/20/848): + Rename all DT compatible properties to be chip specific. + Remove hardware interrupt priorities from interrupt controller DT bindings. + Remove all dependencies on include headers used by PIC32 DTS files. + Remove arch/mips/include/asm/mach-pic32/gpio.h + Drop usage of the following, mostly non-standard, properties in DT bindings: device_type piomode no-1-8-v uart-has-rtscts clock-frequency => assigned-clock-rate + Remove PIC32 memory PLL support from DT. + Replace empty 'ranges' with populated one for clock tree node. + Rename all instances of "USART" to "UART". + Remove 'interrupts' property from FSCM of PIC32 clock tree node. + Add default REFCLK rate initialization required for SDHCI in DTS. + Remove default frequency setup for REFOSC clocks in -clk DTS. + Address missing static on local functions and other sparse warnings in several drivers. + Update pinctrl driver to address major binding and architectural issues. + Remove redundant probing 'pb7_clk' to find CPU clock. + Remove unused PIC32 MPLL support. + Remove support for initializing default parent/rate for REFOSC clocks. + Be consistent and use only "SDHCI" when refering to SD host controller + Remove unecessary PIC32 sdhci_ops min clock function. + Make platform PIC32[_CLR|_SET|_INV] register macros safer.
