Thank you Jonathan, I'll add a new patch set soon, added some comments inline also.

I should have been (much) more specific here: that represents a float number with 4 integer bits and 4 fractional bits (Q4.4), so I find hex more intuitive since it's split in half, let me know if you think otherwise. I'll add a more complete description. As for the "/bits/ x" it's because currently in the driver I use the read_property_u8 or *_u16 functions, these require that the dts entry be as I wrote it in the example, and since it's an example it should be functional, so I feel that is ok as it is. > > >> + }; >> + > One blank line at the end is neough. >> + >> diff --git a/Documentation/devicetree/bindings/vendor-prefixes.txt b/Documentation/devicetree/bindings/vendor-prefixes.txt >> index d444757..5b40bab 100644 >> --- a/Documentation/devicetree/bindings/vendor-prefixes.txt >> +++ b/Documentation/devicetree/bindings/vendor-prefixes.txt >> @@ -211,6 +211,7 @@ toshiba Toshiba Corporation >> toumaz Toumaz >> tplink TP-LINK Technologies Co., Ltd. >> truly Truly Semiconductors Limited >> +upisemi uPI Semiconductor Corp. >> usi Universal Scientific Industrial Co., Ltd. >> v3 V3 Semiconductor >> variscite Variscite Ltd. >> > -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

One for the device tree guys to answer rather than me. My gut feeling would be a representation that made this obvious but I have no idea what normal choice would be. >I'll add a more complete description.
