From ab4efca29f6479bfae6ef433e757014ed6755710 Mon Sep 17 00:00:00 2001 From: Łukasz Stelmach Date: Fri, 2 Oct 2020 14:22:36 +0200 Subject: spi: spi-s3s64xx: Add S3C64XX_SPI_QUIRK_CS_AUTO for Exynos3250 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix issues with DMA transfers bigger than 512 bytes on Exynos3250. Without the patches such transfers fail. The vendor kernel for ARTIK5 handles CS in a simmilar way.
