    Subject[PATCH V5 0/4] additional features to Tegra SPI
    Date
    [V5] : This patch series version includes
    - Updated GPIO based chip select control using GPIO descriptor.
    - HW based chip select implementation is same as V3 but V5
    has this patch updated to be on top of above changes.
    - HW CS timing implementation is same as V3 but V5
    has this patch updated to be on top of above changes.
    - support for TX and RX trimmers implementation is same as V3
    but V5 has this patch updated to be on top of above changes
    and updated commit description.

    [V4] : This version went out accidentally. Please discard.

    [V3] : This patch series version includes
    - only patches that are not applied from V2.
    - splitted expanding mode and adding LSByte First support
    in separate patches and removed DT property for selecting
    LSByte First.
    - Updated GPIO based chip select control to use spi_set_cs
    from SPI core.
    - HW based chip select implementation is same as V2 but V3
    has this patch updated to be on top of above changes.
    - HW CS timing implementation is same as V2 but V3
    has this patch updated to be on top of above changes.
    - support for TX and RX trimmers implementation is same as V2
    but V3 has this patch updated to be on top of above changes
    and updated commit description.

    [V2] : This patch series version includes
    - only patches that are not applied from V1.
    - changed order of patches to include all fixes prior to new features
    support.
    - Removed HW CS timing from DT properties and created set_cs_timing
    SPI master optional method for SPI controllers to implement and
    created API spi_cs_timing for SPI client drivers to request CS
    setup, hold and inactive delay timing configuration.
    - Fixed HW based CS decision to be based on single transfer and
    cs_change. Remove selection of HW based CS through DT.
