    Subject[PATCH v8 0/3] J7200: Add support for GPIO and higher speed modes in MMCSD subsystems
    Date
    The following series of patches
    - Add support for GPIO subsystem in main and wakeup domains.
    - Add voltage regulator device tree nodes and their corresponding pinmux
    to support power cycle and voltage switch required for UHS-I modes
    - sets respective tags in sdhci0 node to support higher speeds
    - remove no-1-8-v tag from sdhci1 node to support UHS-I modes
    - Update delay values for various speed modes supported.


    test logs
    - eMMC HS400 speed mode
    https://pastebin.ubuntu.com/p/pRzV2ZvSJZ/

    - SD SDR104 speed mode
    https://pastebin.ubuntu.com/p/n64PNdDy2v/

    - GPIO logs

    Changes since v7:
    - Added the voltage regulator nodes to indicate the complete
    power flow for MMCSD1 subsystem
    - Corrected minor errors in DT nodes
    - Reran the tests.
    - Rebased the series

    Changes since v6:
    - Corrected the node name from vdd_sd_dv_pins_default to
    vdd-sd-dv-pins-default

    Changes since v5:
    - Corrected the link in patch 3 as it broken.
    - Added the version number for the references used in patch 3.
    - picked up reviewed-by from grygorii for patches 1 and 2.

    Changes since v4:
    - Added main_i2c0 pinmux required for doing power cycles to MMCSD1
    subsystem
    - Updated delay values for various speed modes supported
    - Corrected the ti,ngpio property to indicate highest gpio lines that
    can be accessed.
    - Reran the performace tests

    Changes since v3:
    - Removed patch (1 in v3).
    - Rebased and included patches that add support for GPIO from series [1].
    - Re-ran the performace tests for SD and eMMC.

    Changes since v2:
    - Added main_gpio0 DT node
    - Added voltage regulator device tree nodes required to support UHS-I modes

    Changes since v1:
    - squashed the two patches into one
    - added performance logs for the above mentioned speed modes
