  • 8670b4598   extcon: Use the extcon_set_state_sync() instead of deprecated functions ... Browse Code »

    This patch alters the renamed extcon API to set the state of the external
    connectors instead of deprecated extcon_set_cable_state_().

    Because the patch[1] modifies the function name to maintain the function
    naming pattern.
    - extcon_set_cable_state_() -> extcon_set_state_sync()
    - extcon_get_cable_state_() -> extcon_get_state()

    This patch adds the new EXTCON_CHG_USB_SDP connector to support SDP (Standard
    Downstream Port) USB charging port. The commit 11eecf910bd8 ("extcon: Modify

    connector which support the both data transfer and usb charging at the same

    The function can return negative values, so its result should

    This patch modifies the id and name of external connector with the
    additional prefix to clarify both attribute and meaning of external
    connector as following:
    - EXTCON_CHG_* mean the charger connector.
    - EXTCON_JACK_* mean the jack connector.
    - EXTCON_DISP_* mean the display port connector.

    Following table show the new name of external connector with old name:
    --------------------------------------------------
    Old extcon name | New extcon name |
    --------------------------------------------------
    EXTCON_TA | EXTCON_CHG_USB_DCP |
    EXTCON_CHARGE_DOWNSTREAM| EXTCON_CHG_USB_CDP |
    EXTCON_FAST_CHARGER | EXTCON_CHG_USB_FAST |

    --------------------------------------------------
    EXTCON_MICROPHONE | EXTCON_JACK_MICROPHONE |
    EXTCON_HEADPHONE | EXTCON_JACK_HEADPHONE |
    EXTCON_LINE_IN | EXTCON_JACK_LINE_IN |
    EXTCON_LINE_OUT | EXTCON_JACK_LINE_OUT |
    EXTCON_VIDEO_IN | EXTCON_JACK_VIDEO_IN |
    EXTCON_VIDEO_OUT | EXTCON_JACK_VIDEO_OUT |

    EXTCON_DVI | EXTCON_DISP_DVI |
    EXTCON_VGA | EXTCON_DISP_VGA |
    --------------------------------------------------

    And, when altering the name of USB charger connector, EXTCON refers to the
    "Battery Charging v1.2 Spec and Adopters Agreement"[1] to use the standard
    name of USB charging port as following. Following name of USB charging port
    are already used in power_supply subsystem. We chan check it on patch[2].
    - EXTCON_CHG_USB_SDP /* Standard Downstream Port */
    - EXTCON_CHG_USB_DCP /* Dedicated Charging Port */
    - EXTCON_CHG_USB_CDP /* Charging Downstream Port */

    Pull regulator updates from Mark Brown:
    "The biggest changes in the core this time around have been some
    refactorings that move us towards being able to drop the list of
    regulators maintained by the core and instead just use the driver
    model list maintained for the class devices for regulators which will
    make the code smaller and avoid some potential bugs.

    Otherwise another fairly quiet release for the regulator API,
    highlights include:

    - a new API for setting voltages based on a minimum, target, maximum
    triplet

    - support for continuous voltage ranges rather than tables of
    explicit steps in the PWM regulator, requiring less explicit
    configuration

    - new driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311
    and Qualcomm RPM"

  • 73b6ecdb9   extcon: Redefine the unique id of supported external connectors without 'enum extcon' type ... Browse Code »

    This patch just redefine the unique id of supported external connectors without
    'enum extcon' type. Because unique id would be used on devictree file(*.dts) to
    indicate the specific external connectors like key number of input framework.
    So, I have the plan to move this definitions to following header file which
    includes the unique id of supported external connectors.
    - include/dt-bindings/extcon/extcon.h

  • 2a9de9c0f   extcon: Use the unique id for external connector instead of string ... Browse Code »

    This patch uses the unique id to identify the type of external connector instead
    of string name. The string name have the many potential issues. So, this patch
    defines the 'extcon' enumeration which includes all supported external connector
    on EXTCON subsystem. If new external connector is necessary, the unique id of
    new connector have to be added in 'extcon' enumeration. There are current
    supported external connector in 'enum extcon' as following:

    enum extcon {
    EXTCON_NONE = 0x0,

    /* USB external connector */
    EXTCON_USB = 0x1,
    EXTCON_USB_HOST = 0x2,

    /* Charger external connector */
    EXTCON_TA = 0x10,
    EXTCON_FAST_CHARGER = 0x11,
    EXTCON_SLOW_CHARGER = 0x12,
    EXTCON_CHARGE_DOWNSTREAM = 0x13,

    /* Audio and video external connector */
    EXTCON_LINE_IN = 0x20,
    EXTCON_LINE_OUT = 0x21,
    EXTCON_MICROPHONE = 0x22,
    EXTCON_HEADPHONE = 0x23,

    EXTCON_HDMI = 0x30,
    EXTCON_MHL = 0x31,
    EXTCON_DVI = 0x32,
    EXTCON_VGA = 0x33,
    EXTCON_SPDIF_IN = 0x34,
    EXTCON_SPDIF_OUT = 0x35,
    EXTCON_VIDEO_IN = 0x36,
    EXTCON_VIDEO_OUT = 0x37,

    /* Miscellaneous external connector */
    EXTCON_DOCK = 0x50,
    EXTCON_JIG = 0x51,
    EXTCON_MECHANICAL = 0x52,

    EXTCON_END,
    };

    For example in extcon-arizona.c:
    To use unique id removes the potential issue about handling
    the inconsistent name of external connector with string.
    - Previously, use the string to register the type of arizona jack connector
    static const char *arizona_cable[] = {
    "Mechanical",
    "Microphone",
    "Headphone",
    "Line-out",
    };
    - Newly, use the unique id to register the type of arizona jack connector
    static const enum extcon arizona_cable[] = {
    EXTCON_MECHANICAL,
    EXTCON_MICROPHONE,
    EXTCON_HEADPHONE,
    EXTCON_LINE_OUT,

    EXTCON_NONE,
    };

    And this patch modify the prototype of extcon_{get|set}_cable_state_() which
    uses the 'enum extcon id' instead of 'cable_index'. Because although one more
    extcon drivers support USB cable, each extcon driver might has the differnt
    'cable_index' for USB cable. All extcon drivers can use the unique id number
    for same external connector with modified extcon_{get|set}_cable_state_().

    - Previously, use 'cable_index' on these functions:
    extcon_get_cable_state_(struct extcon_dev*, int cable_index)
    extcon_set_cable_state_(struct extcon_dev*, int cable_index, bool state)

    -Newly, use 'enum extcon id' on these functions:
    extcon_get_cable_state_(struct extcon_dev*, enum extcon id)
    extcon_set_cable_state_(struct extcon_dev*, enum extcon id, bool state)
