Subject: [PATCH v2 1/3] PCI: dwc: Add map irq callback
Date: Tue, 20 Aug 2019 17:39:35 +0800 [thread overview]
Message-ID: <aeda3061a51824cdd7cacab6a1288a155b8ba5e1.1566208109.git.eswara.kota@linux.intel.com> (raw)
In-Reply-To: <cover.1566208109.git.eswara.kota@linux.intel.com>
In-Reply-To: <cover.1566208109.git.eswara.kota@linux.intel.com>
Certain platforms like Intel need to configure
registers to enable the interrupts.
Map Irq callback helps to perform platform specific
configurations while assigning or enabling the interrupts.

Addressing review comments to use if else {} instead of ternary operator
