[PATCH 0/2] ARM: mediatek: Add MT8135 and MT8127 UART support

[PATCH 0/2] ARM: mediatek: Add MT8135 and MT8127 UART support

[Eddie Huang]

3.19-rc1 contains Joe's MT8135 & MT8127 basic support and sysirq driver patch.
But still can not boot to shell due to lack UART device node in device tree.
This patch enables MTK UART driver in multi_v7_defconfig and UART device node.

This patch base on 3.19-rc1, and Joe's sysirq dts patch [1]
