Dear mailing-list,
I am working with the 3.3 kernel on an OMAP4430 with a TWL6030.
I have many warning like the following:
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
I would like to clarify this and eventually "remove" this warning.
I have checked omap_twl.c file. It seems that twl6030_uv_to_vsel()
function have a special branch when uv is equal to 1350000 uV and when
bigger than 1350000 uV it print the error message.
On the same file I could see that on_volt (and the onlp_volt) are set by
default to 1375000 uV for the OMAP4.
On the datasheet of the TWL6030 I could see that the level is 1367400
uV. 1350000 nor than 1375000 are invalid level.
Don't you thin that 1375000 and 1350000 should be the same value ?
If we could change the default on_volt (and the onlp_volt) for the OMAP4
to 1350000 the Warning message will then be removed, and the effective
level on the TWL6030 will still stay to 1367400 uV.
Any comment are welcome !
Patrick
