2014-11-24MIPS: Loongson1B: Add a clockevent/clocksource using PWM TimerKelvin Cheung4-31/+266
This patch add a clockevent/clocksource using PWM Timer for Loongson1B, which is based on earlier work by Tang, Haifeng.

2014-11-24MIPS: Loongson1B: Some fixes/updates for LS1BKelvin Cheung2-23/+130
- Fix hanging ethernet issue of LS1B v2.0 by adding pbl field in plat data. (It seems that the MAC controller of LS1B v2.0 can only accept pbl=1) - Add GMAC1 support and setup MUX in terms of PHY mode. - Add CPUFreq support. - Add MUX Register Definitions. - Add PWM Register Definitions. - Update clock register bitfields according to the latest spec. - Update clock related stuff.

2013-02-19MIPS: early_printk: drop __init annotationsAaro Koskinen1-1/+1
We cannot use __init for earlyprintk code or data, since the kernel parameter "keep_bootcon" allows leaving the boot console enabled. Currently MIPS will crash/hang/die if you use keep_bootcon. The patch fixes it at least on Lemote FuLoong mini-PC. Changes for other boards were done based on what I could find with grep...

Pull MIPS updates from Ralf Baechle: "The MIPS bits for 3.8. This also includes a bunch fixes that were sitting in the linux-mips.org git tree for a long time. This pull request contains updates to several OCTEON drivers and the board support code for BCM47XX, BCM63XX, XLP, XLR, XLS, lantiq, Loongson1B, updates to the SSB bus support, MIPS kexec code and adds support for kdump. When pulling this, there are two expected merge conflicts in include/linux/bcma/bcma_driver_chipcommon.h which are trivial to resolve, just remove the conflict markers and keep both alternatives." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (90 commits) MIPS: PMC-Sierra Yosemite: Remove support.

2012-10-31USB: EHCI: remove ehci_port_power() routineAlan Stern1-1/+0
This patch (as1623) removes the ehci_port_power() routine and all the places that call it. There's no reason for ehci-hcd to change the port power settings; the hub driver takes care of all that stuff. There is one exception: When the controller is resumed from hibernation or following a loss of power, the ports that are supposed to be handed over to a companion controller must be powered on first. Otherwise the handover won't work. This process is not visible to the hub driver, so it has to be handled in ehci-hcd.

2012-07-25MIPS: Loongson 1B: Add board supportKelvin Cheung12-0/+679
Adds basic platform devices for Loongson 1B, including serial port, ethernet, USB, RTC and interrupt handler. The Loongson 1B UART is compatible with NS16550A, the Loongson 1B GMAC is built around a Synopsys IP Core. Use normal instead of enhanced descriptors. Thanks to Giuseppe for updating the normal descriptor in stmmac driver. Thanks to Zhao Zhang for implementing the RTC driver.
