Series | [v2,1/4] ARM: dts: exynos: Disable unused buck10 regulator on Odroid HC1 board | expand |
Hi Krzysztof,
Thanks for this patch. Please add my
Tested-by: Anand Moon <linux.amoon@gmail.com>
[snip]
Could you integrate below small changes into this patch.
with these below changes suspend and resume work correctly at my end.
[1] XU4_suspendresume.patch
As per S2MPS11B PMIC 1.2.1 Regulator (Features)
Fix the min max value for *Buck7* and *Buck8*
-- Buck7 (VDD_1.0V_LDO) 1.5 A (1.2 V to 1.5 V, 12.5 mV step, default on 1.35 V)
-- Buck8 (VDD_1.8V_LDO) 2.5 A (1.8 V to 2.1 V, 12.5 mV step, default on 2.0 V)
Also add suspend-off for *Buck9*
Buck9 internally controls the power of USB hub.
Adding suspend the this node help proper reset of USB hub on Odroid
XU4 / HC1/ XU3
during suspend and resume. Below it the logs from my testing.

Below it the logs from my testing. Disabling Buck9 in suspend indeed reduces the power consumed by the board during suspend-to-ram from about 80mA to as little as 7-10mA, what matches the results of OdroidXU3. Thanks for the hint!

Anand has here valid point - the constraints in DTS do not match hardware manual. This leads to question whether voltage table in driver is proper... Another point is the voltage itself. The schematics describes them as at specific voltage (1.35 V and 2.0 V) but after boot they are 1.2 V and 1.85 V. Maybe this shift comes from the problem above. > > > Also add suspend-off for *Buck9* > > Buck9 internally controls the power of USB hub. > > Adding suspend the this node help proper reset of USB hub on Odroid > > XU4 / HC1/ XU3 > > during suspend and resume.

Thanks for the hint! Although I did not get what is the difference in the logs (Anand pasted two logs but they look the same) but the power consumption is reason is good enough. I would be happy to put in the changelog entire consumption difference. I can measure it on XU3-Lite but can you give me the XU4 (before and after)? Best regards, Krzysztof
