[PATCH v2 00/14] Initial Microchip PIC32MZDA Support

From: Joshua Henderson
Date: Mon Dec 14 2015 - 17:38:16 EST

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 drivers are
included. This has been tested on a PIC32MZDA Starter Kit. A tree with
these changes is available at [0].

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.
