From 2c7d536780600242d804bca1383c896ccff350c4 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Mon, 19 Oct 2015 10:08:18 +0000 Subject: [PATCH] lantiq: Fixed reading the number of RX FIFOs in the SPI driver Until now the SPI driver used the TX bits for the RX FIFO. This seems uncritical for now since both are equals on my devices (VR9), but this could cause problems on other SoCs.
