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 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 drivers/mtd/spi-nor/Kconfig | 2 +- drivers/mtd/spi-nor/cadence-quadspi.c | 55 +++++++++++++++++++++++++++++++---- 2 files changed, 50 insertions(+), 7 deletions(-) -- 2.11.0
