  • 60262cd04   timer: Add generic driver for RISC-V privileged architecture defined timer ... Browse Code »

    RISC-V privileged architecture v1.10 defines a real-time counter,
    exposed as a memory-mapped machine-mode register - mtime. mtime must
    run at constant frequency, and the platform must provide a mechanism
    for determining the timebase of mtime. The mtime register has a
    64-bit precision on all RV32, RV64, and RV128 systems.

    Different platform may have different implementation of the mtime
    block hence an API riscv_get_time() is required by this driver for
    platform codes to hide such implementation details. For example,
    on some platforms mtime is provided by the CLINT module, while on
    some other platforms a simple 'rdtime' can be used to get the timer
    counter.

    With this timer driver the U-Boot timer functionalities like delay
    works correctly now.

  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • 1168d2dd4   rockchip: timer: add device-model timer driver for RK3368 (and similar) ... Browse Code »

    This adds a device-model driver for the timer block in the RK3368 (and
    similar devices that share the same timer block, such as the RK3288) for
    the down-counting (i.e. non-secure) timers.

    This allows us to configure U-Boot for the RK3368 in such a way that
    we can run with the secure timer inaccessible or uninitialised (note
    that the ARMv8 generic timer does not count, if the secure timer is
    not enabled).

  • e9e5d9d29   dm: timer: normalise SPL and TPL support ... Browse Code »

    To fully support DM timer in SPL and TPL, we need a few things cleaned
    up and normalised:
    - inclusion of the uclass and drivers should be an all-or-nothing
    decision for each stage and under control of $(SPL_TPL_)TIMER
    instead of having the two-level configuration with TIMER and
    $(SPL_TPL_)TIMER_SUPPORT
    - when $(SPL_TPL_)TIMER is enabled, the ARMv8 generic timer code can
    not be compiled in

    This normalises configuration to $(SPL_TPL_)TIMER and moves the config
    options to drivers/timer/Kconfig (and cleans up the collateral damage
    to some defconfigs that had SPL_TIMER_SUPPORT enabled).

  • ad9b5f77d   drivers: timer: Introduce ARC timer driver ... Browse Code »

    This commit introduces timer driver for ARC.

    ARC timers are configured via ARC AUX registers so we use special
    functions to access timer control registers.

    This driver allows utilization of either timer0 or timer1
    depending on which one is available in real hardware. Essentially
    only existing timers should be mentioned in board's Device Tree
    description.

  • 4697abea6   aspeed: Add drivers common to all Aspeed SoCs ... Browse Code »

    Add support for Watchdog Timer, which is compatible with AST2400 and
    AST2500 watchdogs. There is no uclass for Watchdog yet, so the driver
    does not follow the driver model. It also uses fixed clock, so no clock
    driver is needed.

    Add support for timer for Aspeed ast2400/ast2500 devices.
    The driver actually controls several devices, but because all devices
    share the same Control Register, it is somewhat difficult to completely
    decouple them. Since only one timer is needed at the moment, this should
    be OK. The timer uses fixed clock, so does not rely on a clock driver.

    Add sysreset driver, which uses watchdog timer to do resets and particular
    watchdog device to use is hardcoded (0)
