Subject: [PATCH edk2-platforms v3 10/17] ARM/VExpressPkg: Redefine LcdPlatformGetTimings function
Date: Tue, 20 Mar 2018 16:18:16 +0000 [thread overview]
Message-ID: <20180320161823.54020-11-girish.pathak@arm.com> (raw)
In-Reply-To: <20180320161823.54020-1-girish.pathak@arm.com>
From: EvanLloyd <evan.lloyd at arm.com>
The LcdPlatformGetTimings interface function takes similar sets of
multiple parameters for horizontal and vertical timings which can be
aggregated in a common data type. This change defines a structure
SCAN_TIMINGS for this which can be used to describe both horizontal and
vertical scan timings, and accordingly redefines the
LcdPlatformGetTiming interface, greatly reducing the amount of data
passed about.
Similarly the mode definition tables are also changed to use this data
type and thus enable pass through access.
