From: Sean Wang <[email protected]>
Changes since v4:
- redefine the two dummy clocks with the correct frequency
which is 25MHz and 280MHz respectively.
Changes since v3:
- get rid of those accepted patches
- rebased to branch v4.12-next/dts64 in Matthias' tree
- fixed uart node in dts with two clocks as described in bindings documentation
Changes since v2:
- merge back required basic clock nodes into the .dtsi file
- update the property of interrupts in timer nodes with 2 CPUs
Changes since v1:
- update SPDX-License-Identifier
- remove next-level-cache property since cache geometry detection was removed since 4.12
This patch set adds basic SoC support for MediaTek MT7622
SoC based on 4.12-rc1.
