  • aa1a7fc4a   clk: nomadik: Remove clk.h and clkdev.h includes ... Browse Code »

    Clock provider drivers generally shouldn't include clk.h because
    it's the consumer API. Remove the include here because this is a
    provider driver. This driver also includes clkdev.h even though
    it isn't used, so drop it too and add slab.h to make sure
    everything still compiles.

  • 791ed0bb5   drivers/clk: don't use module_init in clk-nomadik.c which is non-modular ... Browse Code »

    The clk-nomadik.o is built for ARCH_NOMADIK -- which is bool, and
    hence this code is either present or absent. It will never be
    modular, so using module_init as an alias for __initcall can be
    somewhat misleading.

    Fix this up now, so that we can relocate module_init from
    init.h into module.h in the future. If we don't do this, we'd
    have to add module.h to obviously non-modular code, and that
    would be a worse thing.

    Note that direct use of __initcall is discouraged, vs. one
    of the priority categorized subgroups. As __initcall gets
    mapped onto device_initcall, our use of device_initcall
    directly in this change means that the runtime impact is
    zero -- it will remain at level 6 in initcall ordering.

  • ec6deea1a   clk: nomadik: fix multiplatform problem ... Browse Code »

    The Nomadik debugfs screws up multiplatform boots if debugfs
    is enabled on the multiplatform image, since it's a simple
    initcall that is unconditionally executed and reads from certain
    memory locations.

    Fix this by checking that the driver has been properly
    initialized, so a base offset to the Nomadik SRC controller
    exists, before proceeding to register debugfs files.

  • 74227e65f   clk: nomadik: declare OF clock provider ... Browse Code »

    Common clock framework allows to register clock providers to get called
    on of_clk_init() by using CLK_OF_DECLARE. This converts nomadik clock
    provider to make use of it and get rid of the mach specific clk init
    call. As clocks require system reset controller base address to be
    initialized each clock driver checks src_base and calls new
    nomadik_src_init if required.

  • ea25a900f   clk: nomadik: move src init out of nomadik_clk_init ... Browse Code »

    nomadik_clk_init currently also maps system reset controller base address
    used by clocks and registers a reboot notifier. To allow further cleanup of
    nomadik clk setup, this moves system reset controller setup from
    nomadik_clk_init to its own function.

  • eb6b036dd   clk: nomadik: set all timers to use 2.4 MHz TIMCLK ... Browse Code »

    This fixes a regression for the Nomadik on the main system
    timers.

    The Nomadik seemed a bit slow and its heartbeat wasn't looking
    healthy. And it was not strange, because it has been connected
    to the 32768 Hz clock at boot, while being told by the clock driver
    that it was 2.4MHz. Actually connect the TIMCLK to 2.4MHz by
    default as this is what we want for nice scheduling, clocksource
    and clock event.

  • ef6eb322c   clk: nomadik: implement the Nomadik clocks properly ... Browse Code »

    The Nomadik clock implementation was a stub just using
    fixed clocks.

    This implements the clocks properly instead of relying
    on them all being on at boot and leaving them all on.

    The PLLs are on the top locking to the main chrystal
    oscillator, then the HCLK for the peripherals are
    below PLL2.

    The gated clocks are implemented with zero cells and
    given the clock ID as a property of each node, so every
    gate need to have its own node in the device tree.
    This is because the gate registers contain both HCLK
    gates and PCLK gates, where the latter has HCLK as
    parent. As can be seen from the register layout, this
    is a complete mixup, which means all these gates need
    their own node to properly model parent/child relations
    for PCLKs apart from the HCLKs.

    This driver also adds a helpful debugfs file to inspect
    the hardware state of the clock gates.

    This is the end result in /clk/clk_summary
    after applying a proper device tree:

    The Nomadik NAND driver is really just a subset of the existing
    FSMC driver, so let's switch over to using that driver instead,
    since it handles more variants of this chip. The callbacks for
    setting up the chip is doing stuff now handled by the FSMC
    driver.
