    After realizing that we tend to tell developers the same thing over
    and over, let's attempt to document some commin design patterns
    used in the device drivers. The idea is that this can be extended
    so I just start out with two well-known design patterns.

    …/iio into staging-next

    Jonathan writes:

    First set of new features, drivers and cleanups for IIO in the 3.14 cycle.
    This mostly consists of patches that didn't quite make the last cycle. Lots
    of interesting things under review currently.

    Core:
    - Add devm_iio_device_register/unregister. I took some convincing on whether
    there would be many devices that really were simple enough to need no
    explicit actions on removal. Turns out there are some.
    - Move some stray docs to above the relevant implemenation.
    - Drop a redundant repeated check on the fact the trigger has actually changed
    when there is a userspace attempt change it.

    Drivers:
    New drivers
    - Freescale MPL3115A2 Pressure / temperature sensor

    New functionality
    - hid_sensors: add sensitivity support.

    DT bindings
    - tsl2563
    - hmc5843

    Cleanups
    - Drop unused scan_type from viperboard adc driver.
    - devm_iio_device_register used in viperboard, ad5421, ad5755, adis16130,
    adxrs450, vcnl4000, adis16220, ad7816, lpc32xx, adt7316, adis16060, isl29018
    and ad2s1200. Note that this was proposed in a number of other drivers
    and this revealed a number of missorderings in remove functions. Also for
    now I have blocked this on any device that any hardware suspend suport on
    the basis that we probably want to power down devices if they have no driver
    support loaded.

  • 75096579c   lib: devres: Introduce devm_ioremap_resource() ... Browse Code »

    The devm_request_and_ioremap() function is very useful and helps avoid a
    whole lot of boilerplate. However, one issue that keeps popping up is
    its lack of a specific error code to determine which of the steps that
    it performs failed. Furthermore, while the function gives an example and
    suggests what error code to return on failure, a wide variety of error
    codes are used throughout the tree.

    In an attempt to fix these problems, this patch adds a new function that
    drivers can transition to. The devm_ioremap_resource() returns a pointer
    to the remapped I/O memory on success or an ERR_PTR() encoded error code
    on failure. Callers can check for failure using IS_ERR() and determine
    its cause by extracting the error code using PTR_ERR().

    devm_request_and_ioremap() is implemented as a wrapper around the new
    API and return NULL on failure as before. This ensures that backwards
    compatibility is maintained until all users have been converted to the
    new API, at which point the old devm_request_and_ioremap() function
    should be removed.

    A semantic patch is included which can be used to convert from the old
    devm_request_and_ioremap() API to the new devm_ioremap_resource() API.
    Some non-trivial cases may require manual intervention, though.

    Almost every platform_driver does the three steps get_resource,
    request_mem_region, ioremap. This does not only lead to a lot of code
    duplication, but also a huge number of similar error strings and
    inconsistent error codes on failure. So, introduce a helper function
    which simplifies remapping a resource and make it hard to do something
    wrong and add documentation for it.

  • 13977091a   Driver Core: early platform driver ... Browse Code »

    V3 of the early platform driver implementation.

    Platform drivers are great for embedded platforms because we can separate
    driver configuration from the actual driver. So base addresses,
    interrupts and other configuration can be kept with the processor or board
    code, and the platform driver can be reused by many different platforms.

    For early devices we have nothing today. For instance, to configure early
    timers and early serial ports we cannot use platform devices. This
    because the setup order during boot. Timers are needed before the
    platform driver core code is available. The same goes for early printk
    support. Early in this case means before initcalls.

    These early drivers today have their configuration either hard coded or
    they receive it using some special configuration method. This is working
    quite well, but if we want to support both regular kernel modules and
    early devices then we need to have two ways of configuring the same
    driver. A single way would be better.

    The early platform driver patch is basically a set of functions that allow
    drivers to register themselves and architecture code to locate them and
    probe. Registration happens through early_param(). The time for the
    probe is decided by the architecture code.

    See Documentation/driver-model/platform.txt for more details.
