Subject[PATCH v5 0/2] spi: Add support for Realtek RTL838x/RTL839x SoC SPI
Date
v5:
- Changed SoC compatible to list exact models

v4:
- Added SoC series-specific compatible matches.

v3:
- Added cpu_relax() to busy loop.
- Dropped .remove callback from driver struct.
- Use (variations of) realtek-rtl as prefix.
- Dropped Kconfig entry, and use MACH_REALTEK_RTL setting to build the
driver, since there's no point booting without the SPI-connected flash.

v2:
- Rewrote from spi-nor driver to regular spi driver, implementing only
set_cs() and transfer_one(). (Thanks Chuanhong Guo!)
