[PATCH 0/2] dt-bindings: Add Xuantie Semiconductor Co., Ltd.

[Guo Ren]

From: "GUO Ren (XuanTie)" <guoren@kernel.org>

The RISC-V CPU bindings currently describe the XuanTie C906, C908,
C910 and C920 processors using the historical thead vendor prefix.

Add xuantie as the vendor prefix for Shanghai Xuantie Semiconductor
Technology Co., Ltd., and add corresponding xuantie,* compatible
strings for these processors.

The existing thead,* compatible strings are retained to preserve the
Device Tree ABI and compatibility with existing device trees.

The vendor information is available from the Xuantie declaration
page [1].

  dt-bindings: riscv: Add Xuantie C906/C908/C910/C920 compatibles

[PATCH 2/2] dt-bindings: riscv: Add Xuantie C906/C908/C910/C920 compatibles

[Guo Ren]

From: "GUO Ren (XuanTie)" <guoren@kernel.org>

The RISC-V CPU bindings currently use the historical thead vendor
prefix for the XuanTie C906, C908, C910 and C920 processors.

Add equivalent compatibles using the newly defined xuantie vendor
prefix. Keep the existing thead compatibles to preserve compatibility
with existing device trees.
