From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Boyd Subject: [PATCH v2 0/2] Fix qcom geni i2c DMA handling Date: Thu, 20 Sep 2018 11:03:21 -0700 Message-ID: <20180920180323.217377-1-swboyd@chromium.org> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Wolfram Sang Cc: linux-kernel@vger.kernel.org, linux-i2c@vger.kernel.org, linux-arm-msm@vger.kernel.org, Karthikeyan Ramasubramanian , Sagar Dharia , Girish Mahadevan List-Id: linux-i2c@vger.kernel.org The qcom GENI I2C driver fails DMA sometimes when things from request firmware are passed in as the message buffer. This patch series fixes that problem in the first patch and the second patch cleans up the code a little to reduce lines and simplify lines. Changes from v1: * Use i2c helpers to map buffers * New patch 2 to clean up seriously indented code Cc: Karthikeyan Ramasubramanian Cc: Sagar Dharia Cc: Girish Mahadevan Stephen Boyd (2): i2c: i2c-qcom-geni: Properly handle DMA safe buffers i2c: i2c-qcom-geni: Simplify tx/rx functions drivers/i2c/busses/i2c-qcom-geni.c | 68 +++++++++++++++++------------- 1 file changed, 39 insertions(+), 29 deletions(-) -- Sent by a computer through tubes
