2016-10-05MIPS: SEAD3: Use generic restart-poweroff driverPaul Burton
Remove the custom platform code to restart when instructed to power off, instead relying upon the generic restart-poweroff driver probed via DT to do the same thing. Remove also the halt implementation, which is incorrect. The generic MIPS version will hang the system as halt should.

2016-10-05MIPS: SEAD3: Probe UARTs using DTPaul Burton
Probe the UARTs on SEAD3 boards using device tree rather than platform code, in order to reduce the amount of the latter. This requires that CONFIG_SERIAL_OF_PLATFORM be enabled, so enable it in sead3_defconfig. The SEAD3 DT shim code is extended to read bootloader environment variables to determine the appropriate UART & mode for kernel console output & set the stdout-path property of the chosen node accordingly. In contrast to the old platform code, which appears to have only ever set "console=ttyS0,38400n8r" with the code in console_config never having an effect, this will honor the "yamontty" environment variable to select between the 2 UARTs on the board and then check the "modetty0" or "modetty1" variable as appropriate to determine the UART configuration.

2016-10-05MIPS: SEAD3: Probe interrupt controllers using DTPaul Burton
Probe the CPU interrupt controller & optional Global Interrupt Controller (GIC) using devicetree rather than platform code. Because the bootloader on SEAD3 does not provide a device tree to the kernel & the device tree is always built in, we patch out the GIC node during boot if we detect that a GIC is not present in the system. The appropriate IRQ domain is discovered by platform code setting up device IRQ numbers temporarily. It will be removed by further patches which move the devices towards being probed via device tree. No behavioural change is intended by this patch.

While I don't have a JZ4740-based board with anything connected to the USB host controller, I did test the generic OHCI driver successfully on a JZ4770-based board.

2016-05-13MIPS: tools: Add relocs toolMatt Redfearn
This tool is based on the x86/boot/tools/relocs tool. It parses the relocations present in the vmlinux elf file, building a table of relocations that will be necessary to run the kernel from an address other than its link address. This table is inserted into the vmlinux elf, in the .data.relocs section. The table is subsequently used by the code in arch/mips/kernel/relocate.c (added later) to relocate the kernel. The tool, by default, also marks all relocation sections as 0 length. This is due to objcopy currently being unable to handle copying the relocations between 64 and 32 bit elf files as is done when building a 64 bit kernel.

This patch introduces devicetree for Atheros AR9331 SoC (AKA Hornet). The AR9331 chip is a Wi-Fi System-On-Chip (WiSOC), typically used in very cheap Access Points and Routers.

2016-05-13MIPS: ath79: update devicetree clock support for AR9132Antony Pavlov
Current ath79 clock.c code does not read reference clock and pll setup from devicetree. E.g. you can set any clock rate value in board DTS but it will have no effect on the real clk calculation. This patch fixes some AR9132 devicetree clock support defects: * clk initialization function ath79_clocks_init_dt_ng() is introduced; it actually gets pll block base register address and reference clock from devicetree; * pll register parsing code is moved to the separate ar724x_clk_init() function; this function can be called from platform code or from devicetree code. Also mips_hpt_frequency value is set from dt, so the appropriate clock parameter is added to the cpu@0 devicetree node. The same approach can be used for adding AR9331 devicetree support.

2016-05-13MIPS: dts: qca: ar9132: use short references for dt nodesAntony Pavlov
Here are some Sascha Hauer's arguments for using aliases in the dts files: - using aliases reduces the number of indentations in dts files; - dts files become independent of the layout of the dtsi files (it becomes possible to introduce another bus {} hierarchy between a toplevel bus and the devices when you have to); - less chances for typos. if &i2c2 does not exist you get an error. If instead you duplicate the whole path in the dts file a typo in the path will just create another node.

The TP-LINK TL-WR1043ND board has only one serial port, so replacing the default of 0 with 0 does nothing useful. Moreover, the correct name for aliases node is "aliases" not "alias". An overview of the "aliases" node usage can be found on the device tree usage page at devicetree.org [1]. Also please see chapter 3.3 ("Aliases node") of the ePAPR 1.1 [2].

2016-04-03MIPS: dts: qca: ar9132_tl_wr1043nd_v1.dts: use "ref" for reference clock nameAntony Pavlov
Current ath79 clock.c code does not read reference clock and pll setup from devicetree. The ar724x_clocks_init() function recreates the clocks from scratch so devicetree clock information is dropped. After adding the code which picked up reference clock from devicetree I have found that kernel does not boot anymore. The SPI and UART drivers can't get clk; here are the bootlog error messages: of_serial: probe of 18020000.uart failed with error -22 ath79-spi: probe of 1f000000.spi failed with error -22 The problem is that clock code assumes that reference clock name is "ref" but current dts-file uses another name: "oscillator". This patch fixes the problem by changing external oscillator dt node name to "ref".
