Subject: [PATCH] powerpc: Add a vga alias node for P1022
Date: Mon, 17 Aug 2015 15:50:57 +0800 [thread overview]
Message-ID: <1439797857-32653-1-git-send-email-dongsheng.wang@freescale.com> (raw)
From: Jason Jin <Jason.Jin@freescale.com>
In u-boot, when set the video as console, the name 'vga' is used
as a general name for the video device, during the fdt_fixup_stdout
process, the 'vga' name is used to search in the dtb to setup the
'linux,stdout-path' node. Though the P1022 DIU is not VGA-compatible
device, to meet the 'vga' name used in u-boot, the vga alias node is
added for P1022 in this patch. At the same time, a display alias is
also added so that no other components grow dependencies on the vga
alias node.
