From ec14c5395dfbc1d40a49c9f19d2bfde6739d89d5 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 30 Nov 2015 17:11:43 +0200 Subject: [PATCH 15/16] mfd: intel-lpss: Pass HSUART configuration via properties 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. Signed-off-by: Mika Westerberg Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J.
