[v5,0/2] arm64: dts: meson-g12a: Introduce new DT files for Meson-G12A SoC

Message

Jianxin Pan Sept. 21, 2018, 8:34 a.m. UTC

This attempt will try to add new DT files to support Meson-G12A SoC.

1) first, Please notice that, in this patch series, the DT node about 16M reserved
memory for hwrom is removed, since it's not needed by G12A SoC.
2) second, the pclk for uart_AO need to be fixed once G12A clock_ao driver is
merged. In this version, it rely on bootloader to enable the pclk gate which 
belong to AO clock domain. Please add clk_ignore_unused to bootargs.

Changes since v4 [3]:
 - add chosen and memory node

Changes since v3 [2]:
 - collect Rob's Reviewed-by
 - test on latest v4.20/integ

Changes since v2 [1]:
 - reorder subnodes
 - collect Rob's Reviewed-by

Changes since v1 [0]:
 - fix signoff typo
 - order subnodes by addresses when there is one and alphabetically when there is none

Applied to v4.20/dt64, added Neils' Reviewed-by tag.
