Date: Tue, 12 Jan 2021 11:02:40 -0800 From: Sowjanya Komatineni <skomatineni@...dia.com> To: <thierry.reding@...il.com>, <jonathanh@...dia.com>, <digetx@...il.com>, <wsa@...-dreams.de>, <skomatineni@...dia.com> CC: <linux-tegra@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <linux-i2c@...r.kernel.org> Subject: [PATCH v3] Create i2c_writesl_vi() to use with VI I2C Patch in this series is to fix known hardware bug with VI I2C controller where immediate multiple writes to TX_FIFO gets stuck resulting in VI I2C controller to be in bad state. Delta between patch versions: [v3]: Includes v2 feedback - uses relaxed writel and readl - avoids type casting on data buffer during i2c_writesl_vi() - updated comment to clearly mention this as workaround to known hardware bug with VI I2C. [v2]: Creates i2c_writesl_vi() for vi i2c based on v1 feedback. [v1]: Updates i2c_writesl() to use writel() followed by i2c_readl().
