[PATCH v1 11/13] mfd: intel-lpss: Pass HSUART configuration via properties

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

From: Mika Westerberg <mika.westerberg@linux.intel.com>

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.
