[PATCH v2] ARM: dts: Exynos5420: Add device nodes for TMU blocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Exynos5420 SoC has per core thermal management unit.
5 TMU channels 4 for CPUs and 5th for GPU.

This patch adds the device tree nodes to the DT device list.

Nodes carry the misplaced second base address and the second
clock to access the misplaced base address.

Changes since v1:
1. Nodes carry the misplaced second base address and the second
   clock to access the misplaced base address.
2. Correct the clock number for the TMU4
