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.
