  • 7232398ab   ARM: tegra: Convert PMC to a driver ... Browse Code »
    26

    This commit converts the PMC support code to a platform driver. Because
    the boot process needs to call into this driver very early, also set up
    a minimal environment via an early initcall.

  • 24fa5af81   soc/tegra: fuse: Set up in early initcall ... Browse Code »

    Rather than rely on explicit initialization order called from SoC setup
    code, use a plain initcall and rely on initcall ordering to take care of
    dependencies.

    This driver exposes some functionality (querying the chip ID) needed at
    very early stages of the boot process. An early initcall is good enough
    provided that some of the dependencies are deferred to later stages. To
    make sure any abuses are easily caught, output a warning message if the
    chip ID is queried while it can't be read yet.

  • a2686766c   soc/tegra: Implement runtime check for Tegra SoCs ... Browse Code »

    Subsequent patches will move some of the initialization code from SoC
    setup code to regular initcalls. To prevent breakage on other SoCs in
    multi-platform builds, these initcalls need to check that they indeed
    run on Tegra.

  • 2fa937a76   soc/tegra: fuse: fix dummy functions ... Browse Code »

    The Tegra fuse header's dummy functions for the case where Tegra20 is
    disabled are inconsistent with the correct prototypes, and have some
    syntax errors. Fix these. While at it, fix the indentation level of
    the dummy function bodies.

  • 0d827a434   soc/tegra: fuse: move APB DMA into Tegra20 fuse driver ... Browse Code »

    The Tegra20 fuse driver is the only user of tegra_apb_readl_using_dma().
    Therefore we can simply the code by incorporating the APB DMA handling into
    the driver directly. tegra_apb_writel_using_dma() is dropped because there
    are no users.

    Implement fuse driver for Tegra20, Tegra30, Tegra114 and Tegra124. This
    replaces functionality previously provided in arch/arm/mach-tegra, which
    is removed in this patch.

    While at it, move the only user of the global tegra_revision variable
    over to tegra_sku_info.revision and export tegra_fuse_readl() to allow
    drivers to read calibration fuses.

  • 5d144e36b   soc: qcom: Add GSBI driver ... Browse Code »

    The GSBI (General Serial Bus Interface) driver controls the overarching
    configuration of the shared serial bus infrastructure on APQ8064, IPQ8064, and
    earlier QCOM processors. The GSBI supports UART, I2C, SPI, and UIM
    functionality in various combinations.

  • 3a6e08218   soc: Introduce drivers/soc place-holder for SOC specific drivers ... Browse Code »

    Based on earlier thread "https://lkml.org/lkml/2013/10/7/662" and
    discussion at Kernel Summit'2013, it was agreed to create
    'driver/soc' for drivers which are quite SOC specific.

    Further discussion on the subject is in response to
    the earlier version of the patch is here:
