Merge tag 'spi-nor/for-4.19' of git://git.infradead.org/linux-mtd into mtd/next
Pull SPI NOR updates from Boris Brezillon:
"
Core changes:
- Apply reset hacks only when reset is explicitly marked as broken in
the DT
Driver changes:
- Minor cleanup/fixes in the m25p80 driver
- Release flash_np in the nxp-spifi driver
- Add suspend/resume hooks to the atmel-quadspi driver
- Include gpio/consumer.h instead of gpio.h in the atmel-quadspi driver
- Use %pK instead of %p in the stm32-quadspi driver
- Improve timeout handling in the cadence-quadspi driver
- Use mtd_device_register() instead of mtd_device_parse_register() in
the intel-spi driver
