- interrupt-parent : The phandle for the interrupt controller
- reg : Address range of the thermal registers. For soc's which has multiple
instances of TMU and some registers are shared across all TMU's like
interrupt related then 2 set of register has to supplied. First set
belongs to each instance of TMU and second set belongs to common TMU
registers.
belongs to register set of TMU instance and second set belongs to
registers shared with the TMU instance.
NOTE: On Exynos5420, the TRIMINFO register is misplaced for TMU
channels 2, 3 and 4
Use "samsung,exynos5420-tmu-ext-triminfo" in cases, there is a misplaced
register, also provide clock to access that base.
TRIMINFO at 0x1006c000 contains data for TMU channel 3
TRIMINFO at 0x100a0000 contains data for TMU channel 4
TRIMINFO at 0x10068000 contains data for TMU channel 2
- interrupts : Should contain interrupt for thermal system
- clocks : The main clock for TMU device
- clocks : The main clocks for TMU device
-- 1. operational clock for TMU channel
-- 2. optional clock to access the shared registers of TMU channel
- clock-names : Thermal system clock name
-- "tmu_apbif" operational clock for current TMU channel
-- "tmu_triminfo_apbif" clock to access the shared triminfo register
for current TMU channel
- vtmu-supply: This entry is optional and provides the regulator node supplying
voltage to TMU. If needed this entry can be placed inside
board/platform specific dts file.
