    Subject[PATCH v7 RESEND 01/13] Revert "ARM: dts: imx6q: Use correct SDMA script for SPI5 core"
    Date
      There are two ways for SDMA accessing SPBA devices: one is SDMA->AIPS
    ->SPBA(masterA port), another is SDMA->SPBA(masterC port). Please refer
    to the 'Figure 58-1. i.MX 6Dual/6Quad SPBA connectivity' of i.mx6DQ
    Reference Manual. SDMA provide the corresponding app_2_mcu/mcu_2_app and
    shp_2_mcu/mcu_2_shp script for such two options. So both AIPS and SPBA
    scripts should keep the same behaviour, the issue only caught in AIPS
    script sounds not solide.
    The issue is more likely as the ecspi errata
    ERR009165(http://www.nxp.com/docs/en/errata/IMX6DQCE.pdf):
    eCSPI: TXFIFO empty flag glitch can cause the current FIFO transfer to
    be sent twice
    So revert commit 'df07101e1c4a' firstly.
