  • 3b2663ca8   mips: delete non-required instances of include <linux/init.h> ... Browse Code »

    None of these files are actually using any __init type directives
    and hence don't need to include . Most are just a
    left over from __devinit and __cpuinit removal, or simply due to
    code getting copied from one driver to the next.

    In commit 15ef17f622033455dcf03ae96256e474073a7b11
    (tty: ar933x_uart: use the clk API to get the uart
    clock), the AR933x UART driver for has been converted
    to get the uart clock rate via the clock API and it
    does not use the platform data anymore.

    Remove the ar933x_uart_platform.h header file and get
    rid of the superfluous variable and initialization code
    in platform setup.

  • 2c4f1ac56   MIPS: ath79: Switch to the clkdev framework ... Browse Code »

    The ath79 code uses static clock devices and
    provides its own clk_{get,put} implementations.

    Change the code to use dynamically allocated
    clock devices and register the clocks within
    the clkdev framework.

    Additionally, remove the local clk_{get,put}
    implementation. The clkdev framework has a
    common implementation of those.

    Also move the call of ath79_clock_init() from
    plat_mem_init() to plat_time_init(). Otherwise
    it would not be possible to use memory allocation
    functions from ath79clock_init() becasuse the
    memory subsystem is not yet initialized when
    plat_mem_init() runs.

  • 59a8c10b2   MIPS: ath79: Use ath79_get_sys_clk_rate to get basic clock rates ... Browse Code »

    Instead of accessing the rate field of the static
    clock devices directly, use the recently introduced
    helper function to get the rate of the basic clocks.

    The static ath79_{ahb,cpu,ddr,ref}_clk variables
    will be removed by a subsequent patch. The actual
    change is in preparation of that.

    Also move the clock frequency printing code into
    the plat_time_init function. We are getting the
    cpu clock rate there already so we can save an
    extra call of the helper.

    The ath79 platform uses similar code to get the
    rate of various clocks during init. Separate the
    similar code into a new helper function and use
    that to avoid code duplication.

  • a1191927a   MIPS: ath79: Fix ar933x watchdog clock ... Browse Code »

    The watchdog device on the AR933x is connected to
    the AHB clock, however the current code uses the
    reference clock. Due to the wrong rate, the watchdog
    driver can't calculate correct register values for
    a given timeout value and the watchdog unexpectedly
    restarts the system.

    The code uses the wrong value since the initial
    commit 04225e1d227c8e68d685936ecf42ac175fec0e54
    (MIPS: ath79: add AR933X specific clock init)

    The patch fixes the code to use the correct clock
    rate to avoid the problem.

    13

    commit 3747069b25e419f6b51395f48127e9812abc3596 upstream.

    The __cpuinit type of throwaway sections might have made sense
    some time ago when RAM was more constrained, but now the savings
    do not offset the cost and complications. For example, the fix in
    commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
    is a good example of the nasty type of bugs that can be created
    with improper use of the various __init prefixes.

    After a discussion on LKML[1] it was decided that cpuinit should go
    the way of devinit and be phased out. Once all the users are gone,
    we can then finally remove the macros themselves from linux/init.h.

    Note that some harmless section mismatch warnings may result, since
    notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
    and are flagged as __cpuinit -- so if we remove the __cpuinit from
    the arch specific callers, we will also get section mismatch warnings.
    As an intermediate step, we intend to turn the linux/init.h cpuinit
    related content into no-ops as early as possible, since that will get
    rid of these warnings. In any case, they are temporary and harmless.

    Here, we remove all the MIPS __cpuinit from C code and __CPUINIT
    from asm files. MIPS is interesting in this respect, because there
    are also uasm users hiding behind their own renamed versions of the
    __cpuinit macros.

  • 09f5100a5   watchdog: ath79_wdt: get register base from platform device's resources ... Browse Code »

    The ath79_wdt driver uses a fixed memory address
    currently. Although this is working with each
    currently supported SoCs, but this may change
    in the future. Additionally, the driver includes
    platform specific header files in order to be
    able to get the memory base of the watchdog
    device.

    The patch adds a memory resource to the platform
    device, and converts the driver to get the base
    address of the watchdog device from that.

    Remove the static watchdog device variable and use

    allocate and register the device in one step.

    This allows us to save a few bytes in the kernel image.
