[PATCH] perf/amlogic: resolve conflict between canvas & pmu

Marc Gonzalez marc.w.gonzalez at free.fr
Thu Mar 23 09:23:57 PDT 2023


According to S905X2 Datasheet - Revision 07:

DMC_MON area spans 0xff638080-0xff6380c0
DDR_PLL area spans 0xff638c00-0xff638c34

Round DDR_PLL area size up to 0x40

Fixes: 90cf8e21016f ("arm64: dts: meson: Add DDR PMU node")
