Subject: [PATCH v6 0/8] Add QPIC SPI NAND driver

v6:
 * Added FIELD_PREP() and GENMASK() macro
 * Added qpic_spi_nand{..} structure for
   spi nand realted variables
 * Made qpic_common.c slectable based on
   either CONFIG_MTD_NAND_QCOM or CONFIG_SPI_QPIC_SNAND
 * Removed rawnand.h from qpic-common.h 
 * Removed partitions.h and rawnand.h form spi-qpic-snand.c
 * Added qcom_nand_unalloc() in remove()

v5:
 * Fixes nandbiterr issue
 * Added raw_read() and raw_write() API
 * Added qcom_ prefix to all the common API
 * Removed register indirection
 * Following tests for SPI-NAND devices passed

   - mtd_oobtest
   - mtd_pagetest
   - mtd_readtest
   - mtd_speedtest
   - mtd_stresstest
   - mtd_subpagetest
   - mtd_nandbiterrs
   - nandtest
   - nanddump
   - nandwrite
   - nandbiterr -i
   - mtd erase
   - mtd write
   - dd
   - hexddump

v4:
 * In this patch series fixes kernel doc for all the cmmon api
 * Also fixes dm-binding commit message
 * Fix qpic_common.c compilation based on config

v3:
 * In this patch series fixes multiple things like
   added clock-name, added _alloc_controller api instead
   of alloc_master, made common apis more generic etc.

 * Addressed all the comment from v2 patch series

v2:
 * https://lore.kernel.org/linux-arm-msm/20240215134856.1313239-1-quic_mdalam@quicinc.com/
 * In this series of patchs we have added basic working QPIC SPI NAND
   driver with READ, WRITE, ERASE etc functionality

 * Addressed all the comments given in RFC [v1] patch

v1:
 * https://lore.kernel.org/linux-arm-msm/20231031120307.1600689-1-quic_mdalam@quicinc.com/
 * Initial set of patches for handling QPIC SPI NAND.
