Merge tag 'spi-nor/for-5.3-v2' of gitolite.kernel.org:pub/scm/linux/kernel/git/mtd/linux into mtd/next

SPI-NOR core changes:
- add support for the mt25ql02g and w25q16jv flashes
- print error in case of jedec read id fails
- is25lp256: add post BFPT fix to correct the addr_width

SPI NOR controller drivers changes:
- intel-spi: Add support for Intel Elkhart Lake SPI serial flash
- smt32: remove the driver as the driver was replaced by spi-stm32-qspi.c
- cadence-quadspi: add reset control

-Required properties:
-- compatible: should be "st,stm32f469-qspi"
-- reg: the first contains the register location and length.
-       the second contains the memory mapping address and length
-- reg-names: should contain the reg names "qspi" "qspi_mm"
-- interrupts: should contain the interrupt for the device
-- clocks: the phandle of the clock needed by the QSPI controller
-- A pinctrl must be defined to set pins in mode of operation for QSPI transfer
-
-Optional properties:
-- resets: must contain the phandle to the reset controller.

-A spi flash must be a child of the nor_flash node and could have some
-properties. Also see jedec,spi-nor.txt.

-- reg: chip-Select number (QSPI controller may connect 2 nor flashes)
