  • 2ab7704a6   orion_wdt: Support for the Orion Watchdog ... Browse Code »

    The Orion watchdog can be found on some Marvell Armada chips.

    This driver is based on the code by Tomas Hlavacek in the CZ.NIC
    turris-omnia-uboot repository, which can be found at
    https://gitlab.labs.nic.cz/turris/turris-omnia-uboot, and that
    one is based on code by Sylver Bruneau. His code is already in
    mainline Linux kernel.

    The code uses the new driver model API.

  • a821c4af7   dm: Rename dev_addr..() functions ... Browse Code »

    These support the flat device tree. We want to use the dev_read_..()
    prefix for functions that support both flat tree and live tree. So rename
    the existing functions to avoid confusion.

    In the end we will have:

    1. dev_read_addr...() - works on devices, supports flat/live tree
    2. devfdt_get_addr...() - current functions, flat tree only
    3. of_get_address() etc. - new functions, live tree only

    All drivers will be written to use 1. That function will in turn call
    either 2 or 3 depending on whether the flat or live tree is in use.

    Note this involves changing some dead code - the imx_lpi2c.c file.

  • 897f70620   watchdog: Migrate OMAP_WATCHDOG to Kconfig ... Browse Code »

    Move this entry to Kconfig. As it is a hardware watchdog, select
    HW_WATCHDOG. While we could default to enabling this for all platforms,
    it is currently only enabled by default on AM33XX, so keep that logic
    today.

    This driver supports ast2500 and ast2400 SoCs.
    Only ast2500 supports reset_mask and thus the option of resettting

    This is a simple uclass for Watchdog Timers. It has four operations:
    start, restart, reset, stop. Drivers must implement start, restart and
    stop operations, while implementing reset is optional: It's default
    implementation expires watchdog timer in one clock tick.

  • 253531bbd   wdog: Add the watchdog driver for MX7ULP. ... Browse Code »

    This driver implements the HW WATCHDOG functions. Which needs
    to set CONFIG_HW_WATCHDOG to use them. This is disabled by default for
    mx7ulp.

    Use watchdog for reset cpu. Implement this in the driver.
    Need to define CONFIG_ULP_WATCHDOG to build it.

  • f861f51c4   ls102xa: Fix reset hang ... Browse Code »

    Since commit 623d96e89aca6("imx: wdog: correct wcr register settings")
    issuing a 'reset' command causes the system to hang.

    Unlike i.MX and Vybrid, the watchdog controller on LS102x is big-endian.

    This means that the watchdog on LS1021 has been working by accident as
    it does not use the big-endian accessors in drivers/watchdog/imx_watchdog.c.
    Commit 623d96e89aca6("imx: wdog: correct wcr register settings") only
    revelead the endianness problem on LS102x.

    In order to fix the reset hang, introduce a reset_cpu() implementation that
    is specific for ls102x, which accesses the watchdog WCR register in big-endian
    format. All that is required to reset LS102x is to clear the SRS bit.

    This approach is a temporary workaround to avoid a regression for LS102x
    in the 2015.10 release. The proper fix is to make the watchdog driver
    endian-aware, so that it can work for i.MX, Vybrid and LS102x.

    We should not simple use "writew(WCR_WDE, &wdog->wcr)" to set
    wcr, since this will override bits set before reset_cpu.

    Use clrsetbits_le16 instead of writew to fix this issue.

  • 5cab87405   watchdog/imx_watchdog: do not set WCR_WDW ... Browse Code »

    with WCR_WDW set, the watchdog won't trigger if we bootet linux and idle
    around while the watchdog is not triggered. It seems the timer makes
    progress very slowly if at all. I managed to remain 20minutes alive
    while the timeout was set to 60secs. It reboots within 60secs if I start
    a busyloop in userland (something like "while (1) { }").

    While I don't see a reason why the WDT should not be running while the
    CPU is in idle, I'm dropping this bit.

  • 85b8c5c4b   Merge branch 'iu-boot/master' into 'u-boot-arm/master' ... Browse Code »

    Conflicts:
    arch/arm/cpu/arm926ejs/mxs/Makefile

    board/corscience/tricorder/Makefile
    board/ppcag/bg0900/Makefile
    drivers/bootcount/Makefile
    include/configs/omap4_common.h
    include/configs/pdnb3.h

    Makefile conflicts are due to additions/removals of
    object files on the ARM branch vs KBuild introduction
    on the main branch. Resolution consists in adjusting
    the list of object files in the main branch version.
    This also applies to two files which are not listed
    as conflicting but had to be modified:

    board/compulab/common/Makefile
    board/udoo/Makefile

    include/configs/omap4_common.h conflicts are due to
    the OMAP4 conversion to ti_armv7_common.h on the ARM
    side, and CONFIG_SYS_HZ removal on the main side.
    Resolution is to convert as this icludes removal of
    CONFIG_SYS_HZ.

    include/configs/pdnb3.h is due to a removal on ARM side.
    Trivial resolution is to remove the file.

    Note: 'git show' will also list two files just because
    they are new:

    include/configs/am335x_igep0033.h
    include/configs/omap3_igep00x0.h
