Wysocki" , Greg Kroah-Hartman , Jarkko Nikula , linux-i2c@vger.kernel.org, linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org, Lee Jones , Mika Westerberg , Kevin Fenzi , Arnd Bergmann , Wolfram Sang Cc: Andy Shevchenko List-Id: linux-i2c@vger.kernel.org From: Mika Westerberg The HS-UART host controller driver needs to know certain properties like width of the register set if it cannot get that information from ACPI or DT. In order to support non-ACPI systems we pass this information to the driver via device properties.
