Date: Fri, 1 Jan 2021 14:24:30 +0100 From: Bert Vermeulen <bert@...t.com> To: Mark Brown <broonie@...nel.org>, Rob Herring <robh+dt@...nel.org>, Birger Koblitz <mail@...ger-koblitz.de>, linux-spi@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Bert Vermeulen <bert@...t.com> Subject: [PATCH v3 0/2] spi: Add support for Realtek RTL838x/RTL839x SoC SPI 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!)
