From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Boyd Subject: [PATCH v3 0/3] Fix qcom geni i2c DMA handling Date: Mon, 24 Sep 2018 16:52:33 -0700 Message-ID: <20180924235235.182649-1-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 , Doug Anderson List-Id: linux-arm-msm@vger.kernel.org (Numbering is weird because I dropped patch 1 but left numbering the same) 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. Cc: Karthikeyan Ramasubramanian Cc: Sagar Dharia Cc: Girish Mahadevan Cc: Doug Anderson Changes from v2: * Dropped first patch because it's applied * New patch 3 to simplify irq handler * Updated patch 2 to hoist out common code and remove 'mode' local variable Changes from v1: * Use i2c helpers to map buffers * New patch 2 to clean up seriously indented code Stephen Boyd (2): i2c: i2c-qcom-geni: Simplify tx/rx functions i2c: i2c-qcom-geni: Simplify irq handler drivers/i2c/busses/i2c-qcom-geni.c | 149 +++++++++++++---------------- 1 file changed, 65 insertions(+), 84 deletions(-) -- Sent by a computer through tubes
