From aad550f93fbc28d562a624700f9c12c9b9055a5e Mon Sep 17 00:00:00 2001 From: Radu Rendec Date: Fri, 18 Aug 2017 17:01:28 +0100 Subject: [PATCH] i2c: ismt: dump registers at the end of transactions This patch dumps general and master registers at the end of transactions when debugging is enabled. Previously, registers were only dumped before submitting new descriptors (at the beginning of transactions). This helps debugging if some registers change as result of a failed transaction (e.g. bits are set in the ERRSTS general register).
