X-Git-Tag: accepted/tizen/unified/20230118.172025~7038^2~100^2~16 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d290da83cb099d2d259d1dedacdf2f0375b2ecf0;p=platform%2Fkernel%2Flinux-rpi.git Merge series "spi: Add support for Realtek RTL838x/RTL839x SoC SPI" from Bert Vermeulen : 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().
