From 4a1ae8be4563d29ddd36f46759191f4e867ed954 Mon Sep 17 00:00:00 2001 From: Bert Vermeulen Date: Mon, 20 Apr 2015 15:53:25 +0200 Subject: spi: rb4xx: Fix set_cs logic. As it turns out, the set_cs() enable parameter refers to the logic level on the CS pin, not the state of chip selection. This broke functionality of the LEDs behind the CPLD, or at least delayed the commands until another one came in to toggle CS.
