      Mark Brown authored
      Hi,
      
      This patchset mainly fixes some recently discovered problems about CS for
      LPSPI module on i.MX8DXLEVK.
      
      Add the dt-bindings description for the new property.

      dt-bindings: lpspi: New property in document DT bindings for LPSPI · 7ac9bbf6
      Clark Wang authored
      Add "fsl,spi-only-use-cs1-sel" to fit i.MX8DXL-EVK.
      Spi common code does not support use of CS signals discontinuously.
      It only uses CS1 without using CS0. So, add this property to re-config
      chipselect value.

      spi: lpspi: fix using CS discontinuously on i.MX8DXLEVK · 2a052590
      Clark Wang authored
      SPI common code does not support using CS discontinuously for now.
      However, i.MX8DXL-EVK only uses CS1 without CS0. Therefore, add a flag
      is_only_cs1 to set the correct TCR[PCS].

      spi: lpspi: Fix kernel warning dump when probe fail after calling spi_register · 16d79185
      Clark Wang authored
      Calling devm_spi_register_controller() too early will cause problem.
      When probe failed occurs after calling devm_spi_register_controller(),
      the call of spi_controller_put() will trigger the following warning dump.
