From 7b3d10cdf54b8bc1dc0da21faed9789ac4da3684 Mon Sep 17 00:00:00 2001 From: Sowjanya Komatineni Date: Tue, 26 Mar 2019 22:56:23 -0700 Subject: [PATCH] spi: tegra114: clear packed bit for unpacked mode Fixes: Clear packed bit when not using packed mode. Packed bit is not cleared when not using packed mode. This results in transfer timeouts for the unpacked mode transfers followed by the packed mode transfers.
