[PATCH 1/2] usb: chipidea: fix mistake in device tree binding of nspire-usb to use vendor name 'lsi' instead of SoC name 'zevio'

[dt.tangr]

From: Daniel Tang <dt.tangr@gmail.com>

The SoC name was mistakenly used instead of the vendor name in the
device tree binding for nspire-usb.

This patch fixes this before the driver becomes widely adopted.

How widely adopted is it so far?

I can't see the binding in mainline yet.

Surely this should be lsi,zevio-usb, matching the lsi,zevio-timer
binding?

Thanks,
Mark.

You're right. I'll fix up the patch and send it back in.

lsi is vendor name, what are zevio and nspire?
Usually, the compatible string should be "vendor_name,soc_name-module_name"

Because this port uses documentation from reverse engineering, it's difficult to work out what is SoC specific and what is device specific. The SoC is Zevio but the driver is written for the TI-Nspire.

If it's usually "vendor_name,soc_name-module_name", I'll fix up this patch with zevio instead of nspire (and it'll be more consistent with the other drivers).

Please wrap the line to 80 characters.

The driver is written for the TI-Nspire, and you port this driver for
SoC Zevio platform? Since you use chipidea ip, we don't care the usb
module name at your platform, we only care the soc name which you are
running, it can detect the SoC platform at runtime.

At your dts patch, it still uses nspire-usb.

The TI-Nspire runs on the Zevio SoC.

Yep, that's why the latest patch I sent in renames the device tree 
binding to "lsi,zevio-usb" since zevio is the name of the SoC that the 
TI-Nspire uses.

I'll send a new one in right now.

OK, in order to avoid changing name again, I will queue your patch at my pending
chipidea tree until your dts has applied by arch or dts maintainer, notify me
when they are ready.
