So my question is, would it make sense to update Kconfig and module name to be "ipu" or if you prefer "intel-idpf" to make it clear this is currently an Intel vendor specific driver? And then when you make it a common standards driver rename it to idpf? The point being to help make sure users are not confused about whether they got a driver with or without IDPF updates. It's not critical I guess but seems like a good idea. WDYT? -- MST
