From a8af5cc2ff1e804694629a8ef320935629dd15ba Mon Sep 17 00:00:00 2001 From: Bert Vermeulen Date: Wed, 20 Jan 2021 14:59:28 +0100 Subject: spi: realtek-rtl: Add support for Realtek RTL838x/RTL839x SPI controllers This driver likely also supports earlier (RTL8196) and later (RTL93xx) SoCs. The SPI hardware in these SoCs is specifically intended for connecting NOR bootflash chips, and only used for that in dozens of examined devices. However boiled down to basics, it's really just a half-duplex SPI controller. The hardware appears to have a vestigial second chip-select control, but it hasn't been seen in the wild and is thus not supported.
