> This patch series adds support for Microchip PIC32MZ[DA] MIPS microcontroller platform.
> All drivers required to boot from MMC uSD card and network are included in it; clock,
> pinctrl, gpio, DDR2, serial, SDHCI, ethernet.
> This series been tested on PIC32MZ[DA] Starter Kit.
>
> This series is generated on u-boot/master branch. A tree with these changes is available
> at [1].

applied to u-boot-mips, thanks

> Changes in v4:
> - update kconfig dependency and default selection
> - drop ioremap failure check
> - gpio: return -EPERM if the pin is found in analog mode
> - gpio: drop desc->offset setting in _gpio_xlate()
> - serial: update comment for _pending_input().
> - serial: rename UART_RX_OERR to UART_RX_OVER.
> - serial: DEBUG_UART_PIC32 now depends on PIC32_SERIAL
> - serial: extract clock-id from device-tree
> - drop forcing DM_SERIAL, PIC32_SERIAL, PIC32_PINCTRL in mach-pic32/Kconfig
> - drop extra includes
> - rename clock compatible to "pic32mzda-clk" from "pic32mzda_clk".
> - fix typo 'clock-cells' to '#clock-cells'
> - create defconfig by 'make savedefconfig'
> - drop explicit SYS_BAUDRATE_TABLE in favor of default one
> - add CD errata under SDHCI_QUIRK_NO_CD
> - eth: drop _dcache_flush/invalidate() helpers for flush/invalidate_dcache_range().
>
> Changes in v3:
> - drop empty choice in mach-pic32/Kconfig
> - add pic32_get_syscfg_base()
> - rename clk-pic32.c to clk_pic32.c
> - update clock binding documentation
> - replace pic32_ioremap() with ioremap()
> - separate MPLL initialization constants
> - read register base from device-tree
> - add/update comments to explain how pinctrl'r works.
> - replace pic32_ioremap() with ioremap().
> - add check on dev_get_addr()
> - remove ofdata_to_platdata, and replace platdata with priv
> - remove special handling of '\r' as being handled by serial-uclass
> - remove loop to wait for space in tx buffer before pumping char
> - annotating fixed table with const
> - fix camel-case in ddr2 timing parameters
> - fix cmd index parameter of host_load_cmd().
> - fix compilation warning
> - drop forcing CONFIG_MIPS_BOOT_* selection in mach-pic32/Kconfig
> - indent assembly instructions in delay slot
> - made GPIO-nodes child of pinctrl-node in devicetree
> - replace pic32_ioremap() with ioremap()
> - drop SKIP_LOWLEVEL_INIT, GBL_DATA_OFFSET from config header
> - move CMD_MEMTEST, CMD_MEMINFO to defconfig
> - increase SYS_MALLOC_F_LEN to 0x600
> - use auto-generated defconfig - no hand edit
> - remove ofdata_to_platdata, and replace platdata with priv
> - replace pic32_ioremap() with ioremap()
> - use distro boot commands from config_distro_bootcmd.h
> - separate old booting logic as legacy_bootcmd
> - merge wrappers with eth operation callbacks
> - read phy address from device-tree
> - rename functions (e.g. _eth_xyz() with pic32_eth_xyz())
>
> Changes in v2:
> - move PIC32 specific headers to arch/mips/mach-pic32/include/mach/
> - define register-base as physical address
> - drop CONFIG_PIC32_SUPPORTS_FDT_BOOT
> - add mpll get clock rate
> - add pinconf routine for configuring pin property
> - fix missing/corrupted chars during baud rate change
> - remove loop until any char is avaialbale in getc()
> - move ddr2 initialization from board/microchip/ to drivers/ddr/microchip
> - drop board_early_init_f
> - use macro LEAF(), END() for lowlevel_init
> - move initialization of board_init_f() argument to common start.S
> - move initdram() from board/microchip/ to mach-pic32/cpu.c
> - remove MIPS virtual address in favor physical one in dts file
> - move CONFIG_SYS_TEXT_BASE (from board/*/config.mk) to include/configs/<board>.h
> - drop sdhci shared bus configuration (for shared interrupt, clock pins)
> - drop shared bus (shared pin selection) configuration.
> - replace unbounded loop with wait_for_bit()
> - replace register access as readl/writel(base + offset)
> - translate (dts provided) physical address to MIPS kseg1 address before use
