* Exynos Thermal Management Unit (TMU)
|
||||
|
||||
** Required properties:
|
||||
|
||||
- compatible : One of the following:
|
||||
"samsung,exynos3250-tmu"
|
||||
"samsung,exynos4412-tmu"
|
||||
"samsung,exynos4210-tmu"
|
||||
"samsung,exynos5250-tmu"
|
||||
"samsung,exynos5260-tmu"
|
||||
"samsung,exynos5420-tmu" for TMU channel 0, 1 on Exynos5420
|
||||
"samsung,exynos5420-tmu-ext-triminfo" for TMU channels 2, 3 and 4
|
||||
Exynos5420 (Must pass triminfo base and triminfo clock)
|
||||
"samsung,exynos5433-tmu"
|
||||
"samsung,exynos7-tmu"
|
||||
- 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 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 clocks for TMU device
|
||||
-- 1. operational clock for TMU channel
|
||||
-- 2. optional clock to access the shared registers of TMU channel
|
||||
-- 3. optional special clock for functional operation
|
||||
- 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
|
||||
-- "tmu_sclk" clock for functional operation of the current TMU
|
||||
channel
|
||||
|
||||
The Exynos TMU supports generating interrupts when reaching given
|
||||
temperature thresholds. Number of supported thermal trip points depends
|
||||
on the SoC (only first trip points defined in DT will be configured):
|
||||
- most of SoC: 4
|
||||
- samsung,exynos5433-tmu: 8
|
||||
- samsung,exynos7-tmu: 8
|
||||
|
||||
** Optional properties:
|
||||
|
||||
- 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.
|
||||
|
||||
Example 1):
|
||||
|
||||
tmu@100c0000 {
|
||||
compatible = "samsung,exynos4412-tmu";
|
||||
interrupt-parent = <&combiner>;
|
||||
reg = <0x100C0000 0x100>;
|
||||
interrupts = <2 4>;
|
||||
clocks = <&clock 383>;
|
||||
clock-names = "tmu_apbif";
|
||||
vtmu-supply = <&tmu_regulator_node>;
|
||||
#thermal-sensor-cells = <0>;
|
||||
};
|
||||
|
||||
Example 2): (In case of Exynos5420 "with misplaced TRIMINFO register")
|
||||
tmu_cpu2: tmu@10068000 {
|
||||
compatible = "samsung,exynos5420-tmu-ext-triminfo";
|
||||
reg = <0x10068000 0x100>, <0x1006c000 0x4>;
|
||||
interrupts = <0 184 0>;
|
||||
clocks = <&clock 318>, <&clock 318>;
|
||||
clock-names = "tmu_apbif", "tmu_triminfo_apbif";
|
||||
#thermal-sensor-cells = <0>;
|
||||
};
|
||||
|
||||
tmu_cpu3: tmu@1006c000 {
|
||||
compatible = "samsung,exynos5420-tmu-ext-triminfo";
|
||||
reg = <0x1006c000 0x100>, <0x100a0000 0x4>;
|
||||
interrupts = <0 185 0>;
|
||||
clocks = <&clock 318>, <&clock 319>;
|
||||
clock-names = "tmu_apbif", "tmu_triminfo_apbif";
|
||||
#thermal-sensor-cells = <0>;
|
||||
};
|
||||
|
||||
tmu_gpu: tmu@100a0000 {
|
||||
compatible = "samsung,exynos5420-tmu-ext-triminfo";
|
||||
reg = <0x100a0000 0x100>, <0x10068000 0x4>;
|
||||
interrupts = <0 215 0>;
|
||||
clocks = <&clock 319>, <&clock 318>;
|
||||
clock-names = "tmu_apbif", "tmu_triminfo_apbif";
|
||||
#thermal-sensor-cells = <0>;
|
||||
};
|
||||
|
||||
Note: For multi-instance tmu each instance should have an alias correctly
|
||||
numbered in "aliases" node.
|
||||
|
||||
Example:
|
||||
|
||||
aliases {
|
||||
tmuctrl0 = &tmuctrl_0;
|
||||
tmuctrl1 = &tmuctrl_1;
|
||||
tmuctrl2 = &tmuctrl_2;
|
||||
};
