From 019a8e69a1dc0c0f011fabd0372e1ba80e40dd7c Mon Sep 17 00:00:00 2001 From: Yangyu Chen Date: Sun, 21 Apr 2024 23:52:09 +0800 Subject: [PATCH] platform: generic: thead: add Canaan Kendryte K230 Canaan Kendryte K230 SoC has T-Head C908 cores inside. The dt-binding has been merged into the linux kernel [1]. However, it has early version of C908 core which does not have Sscofpmf and need to use T-Head PMU extension. Thus, we add a K230 compatible string to thead_generic_match and set quirk for T-Head PMU.
