From f6bbb9f531c601135a75ba96e17196c1f745c4ed Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 6 Aug 2019 12:43:20 +0300 Subject: [PATCH] serial: 8250_lpss: register DMA IRQ and pool with instance ID It is really useful not only for debugging to have an DMA IRQ line and pool being mapped to the corresponding IP by using its instance ID. Provide PCI device and function as instance ID for Intel Quark UART DMA.
