Subject: [PATCH v4 0/2] mtd: spi-nor: cadence-quadspi: Disable the DAC and Autopoll for Intel LGM SoC

On Intel Lightning Mountain SoCs QSPI controller do not use auto-poll
and Direct Access Controller (DAC).

Thanks vignesh for your time to review the patch.
The following comments are addressed..
changes from v3:
- commit messages are updated in both the patches
- moved cqspi_disable_auto_poll() in cqspi_controller_init()
- moved the check <if (ddata && (ddata->quirks & CQSPI_DISABLE_DAC_MODE))> in cqspi_setup_flash()
- introduced cqspi->auto_poll variable instead of f_pdata->use_direct_mode for auto_poll patch 
  
Ramuthevar Vadivel Murugan (2):
  mtd: spi-nor: cadence-quadspi: Disable the DAC for Intel LGM SoC
  - This patch adds a quirk to disable the Direct Access Controller
    for data transfer instead it uses indirect data transfer.    	

  mtd: spi-nor: cadence-quadspi: Disable the auto-poll for Intel LGM SoC
  - This patch disables auto polling when direct access mode is disabled
