* ramips: mt7621: add compatible stringsL. D. Pinney2017-07-291-0/+1
| | | | | | | Add compatible strings to all mt7621 based device tree source files to fix formal issues. Signed-off-by: L. D. Pinney <ldpinney@gmail.com>
* ramips: RB750Gr3: Add pwr LED and buzzer to DTSAndrew Yong2016-12-011-1/+12
| | | | | | | | | use pwr LED in diag.sh Expose unused pinmux pins as GPIOs export power LED and buzzer pins Use rb750gr3:blue:pwr LED in diag.sh for boot status instead of rb750gr3:green:usr Signed-off-by: Andrew Yong <me@ndoo.sg>
* ramips: cleanup dts files of mt7621 based boardsMathias Kresin2016-11-231-10/+2
| | | | | | | | | | | | | | | | | | | | Fix a typo in mt7621.dtsi compatible string. Disable spi, sdhci and pci in mt7621.dtsi and enable the nodes in the indiviual board dts files. The nodes require further device specific configuration anyway. Remove the m25p80@0 spi child node from mt7621.dtsi and add the chunked-io parameter to the individual board dts files. Fix the spi flash compatible string for the WNDR3700V5. Drop the mt7621-eval-board compatible string for all boards which are not the eval board. Drop the linux,modalias parameter from spi flash node. Remove the xhci node from board files, it is already enabled in dtsi. Disable xhci for boards not having usb ports populated.

* ramips: add support for MikroTik hEX v3 (RB750Gr3)Andrew Yong2016-11-021-0/+121
The MikroTik hEX v3 (RB750Gr3) is a MT7621AT board which is similar to most MT7621 reference designs, it can be easily supported by this patch; however, the stock RouterBOOT bootloader has to be replaced by a MT7621 SDK U-Boot such as https://github.com/ndoo/RB750Gr3-U-Boot - U-Boot configured for the RB750Gr3 (16MiB SPI flash, 256MiB DDR3 RAM at 1200MHz). RouterBOOT, the stock bootloader, does not initialize the UART and boots silently, making it preferable to replace it with a MT7621 SDK U-Boot with UART (57600 8N1) that supports HTTP, TFTP or serial upload of sysupgrade firmware and U-Boot. Furthermore, RouterOS, the stock firmware, is contained in a proprietary modification of SquashFS without GPL sources; UART is also disabled in stock firmware. The combination of LEDE firmware generated by this PR and MT7621 SDK U-Boot expects the printed MAC address to reside at offset `0xe000` of the factory partition (absolute offset is `0x4e000`); this is similar to the factory MAC address offset for several other MT7621 devices. A 16MiB flash dump suitable for use with flashrom will be provided if/once this patch is accepted and binaries are built by LEDE buildbot. Alternatively, writing the U-Boot to the SPI flash starting at 0x0 offset and booting the board with serial console attached will allow TFTP, HTTP or serial upload of sysupgrade firmware.
