      net: ti: icssg_prueth: Enable 10M Link issue quirk for AM64x · 6de6e418
      MD Danish Anwar authored
      
      There is a HW errata for 10M issues which is present on AM65x but not on
      AM64x. The workaround for this errata is to enable IEP1. Since both
      AM64x and AM65x shares the same ICSSG firmware, firmware is expecting
      IEP1 to be enabled for both AM64x and AM65x. As a result 10M Link fails
      on AM64x.
      
      Enable the quirk_10m_link_issue so that IEP1 can be enabled for AM64x

      spi: cadence-quadspi: Enable PHY for data writes · 5e5ff8fc
      Santhosh Kumar K authored
      
      PHY is tuned with optimal tuning point which allows controller to
      run at higher speeds. Hence, increase the data writes' throughput in
      OSPI/QSPI NAND flashes by enabling PHY for data writes to the NAND
      flash devices.
      
      The aim is to enable PHY only for the OSPI/QSPI NAND data writes,
      so, exclude other operations like register writes to NAND flashes,
      register and data writes to NOR flashes by introducing a check for
      the 'n_tx' (op->data.nbytes) value before enabling.
      
      Currently, OSPI/QSPI NOR's highest page size is 512 bytes, so, check
      whether 'n_tx' is greater than or equal to 1024.

      spi: cadence-quadspi: Move cqspi_phy_enable() and cqspi_readdata_capture() · c98bd8c1
      Santhosh Kumar K authored
      
      Utilising PHY is limited to read operation, but, PHY can be enabled
      for data writes, register reads and/or writes in future. Hence, move
      the cqspi_phy_enable() and cqspi_readdata_capture() functions above
      all the read and write operations.
