    The only usage of these are to assign their address to the ops field in
    the regulator_desc struct, which is a const pointer. Make them const to
    allow the compiler to put them in read-only memory.

  • a70f0d027   regulator: tps6586x: silence pointer-to-int-cast ... Browse Code »

    of_regulator_match.driver_data is (void *). tps6586x uses it to store an
    anonymous enum value (those TPS6586X_ID_ values).

    Later, it tries to extract the ID by casting directly to an int, which is a
    no-no ([-Wpointer-to-int-cast]):

    drivers/regulator/tps6586x-regulator.c: In function 'tps6586x_parse_regulator_dt':
    drivers/regulator/tps6586x-regulator.c:430:8: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
    id = (int)tps6586x_matches[i].driver_data;
    ^

    Instead of casting to int, uintptr_t is better suited for receiving and
    comparing integers extracted from void *. This is especially true on
    64-bit systems where sizeof(void *) != sizeof(int).

  • 844a4f0d8   regulator: tps6586x: Add and use correct voltage table ... Browse Code »

    Depending on the regulator version, the voltage table might be
    different. Use version specific regulator tables in order to select
    correct voltage table. For the following regulator versions different
    voltage tables are now used:

    * TPS658623: Use correct voltage table for SM2
    * TPS658643: New voltage table for SM2

    Both versions are in use on the Colibri T20 module. Make use of the
    correct tables by requesting the correct SM2 voltage of 1.8V.

    This change is not backward compatible since an old driver is not able
    to correctly set that value. The value 1.8V is out of range for the old
    driver and will refuse to probe the device. The regulator starts with
    default settings and the driver shows appropriate error messages.

    On Colibri T20, the old value used to work with TPS658623 since the
    driver applied a wrong voltage table too. However, the TPS658643 used
    on V1.2 devices uses yet another voltage table and those broke that
    pseudo-compatibility. The regulator driver now has the correct voltage
    table for both regulator versions and those the correct voltage can be
    used in the device tree.

  • 712c967fe   regulator: tps6586x: get regulators node from parent node only ... Browse Code »

    As per the devicetree binding document of TPS6586x, the "regulators"
    subnode should be under the parent node, not outside of parent node.
    Hence to get the regulator node, the correct call is
    of_get_child_by_name() rather than of_find_node_by_name() which searches
    the "regulators" node from the parent node to end of DTS file.

  • 64e481603   mfd: tps6586x: move regulator dt parsing to regulator driver ... Browse Code »

    Moving regulator node parsing to regulator driver in place
    of parsing it on mfd driver.
    The motivation for this change are:
    - MFD core driver should not depends on regulator and able
    to instantiate device without regulator.
    - The API for matching regulators are in regulator core and
    it is good that regulator driver only calls this API.
    - Regulator specific support should be in regulator driver only
    to ease any enhancement/modification for regulators.
    - The regulator driver is now registered as mfd sub device and
    all regulator registration is done from single probe call.

  • c172708d3   regulator: core: Use a struct to pass in regulator runtime configuration ... Browse Code »
    129

    Rather than adding new arguments to regulator_register() every time we
    want to add a new bit of dynamic information at runtime change the function
    to take these via a struct. By doing this we avoid needing to do further
    changes like the recent addition of device tree support which required each
    regulator driver to be updated to take an additional parameter.

    The regulator_desc which should (mostly) be static data is still passed
    separately as most drivers are able to configure this statically at build
    time.
