When I was reviewing a kernel-patchset from a Logan-guy, I asked him to combine some of his patches, since in fact their combination represented one solid driver. I was told to go very far, and Greg supported him with it. I'm not going to be that rude and will do as you asked me to. But really, isn't it possible to have some strict rule created so a developer would always follow it thereby not being asked to combine/split patches almost everytime? The only way I see for now is to know each maintainer personal preferences. > > drivers/usb/misc/usb251xb.c | 84 +++++++++++++++++++--- > > 2 files changed, 78 insertions(+), 10 deletions(-) > > > > diff --git a/Documentation/devicetree/bindings/usb/usb251xb.txt b/Documentation/devicetree/bindings/usb/usb251xb.txt > > index 3957d4eda..3d84626d3 100644 > > --- a/Documentation/devicetree/bindings/usb/usb251xb.txt > > +++ b/Documentation/devicetree/bindings/usb/usb251xb.txt > > @@ -6,7 +6,8 @@ Hi-Speed Controller. > > Required properties : > > - compatible : Should be "microchip,usb251xb" or one of the specific types: > > "microchip,usb2512b", "microchip,usb2512bi", "microchip,usb2513b", > > - "microchip,usb2513bi", "microchip,usb2514b", "microchip,usb2514bi" > > + "microchip,usb2513bi", "microchip,usb2514b", "microchip,usb2514bi", > > + "microchip,usb2517", "microchip,usb2517i" > > - reset-gpios : Should specify the gpio for hub reset > > - reg : I2C address on the selected bus (default is <0x2C>) > > > > @@ -36,6 +37,7 @@ Optional properties : > > an invalid value is given, the default is used instead. > > - compound-device : indicate the hub is part of a compound device > > - port-mapping-mode : enable port mapping mode > > + - speed-led-mode : led speed indiation mode selection (usb2517 only) > > This is a boolean or has values?

The new device got almost the same functionality as the others, except number or ports, LED feature and battery enable feature. The last one isn't configurable by dts. The rest of the properties are the same for all the compatible devices.
