And again full support from me here. It's a really very strange position of STMicro here. I as a maintainer / reviewer / supporter of a lot of hardware have a good example of collaboration with contributors from other companies when they do improve our drivers. And I have been doing the same for others, for example Synopsys DesignWare SATA driver which had been found on PPC44x platform. > One of the devices I used > to reverse engineer that hardware had one of these Silan parts, I > noticed the registers looked exactly the same as ST parts supported in > the kernel already and upon testing they worked so I thought it was > worth throwing this out there.
