From fb93bd8d264c3198f321dc23a83559fcfcc275d4 Mon Sep 17 00:00:00 2001 From: Julien Panis Date: Mon, 29 May 2023 15:42:28 +0200 Subject: drivers: spi: omap3_spi: Initialize mode for all channels At first SPI transfers, multiple chip selects can be enabled simultaneously. This is due to chip select polarity, which is not properly initialized for all channels. This patch fixes the issue.
