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.
