The call op requests that the callee pass a message to the underlying HW or device, wait for a response, and then pass back the response error code and message to the callee. It is useful for drivers that represent some kind of messaging or IPC channel to a remote device.

v4: Adjust misc_call() to return the response msg size on success. v3: New patch.

Are you planning for the Tegra186 stuff to go into the upcoming release?
I'd like it to if at all possible; it's all pretty much Tegra-specific drivers so shouldn't cause any fallout for other platforms. The only exception is the fdt_translate_address() changes, which are a dependency, which will be built into other platforms, but there's a simple Boolean parameter that controls the new behaviour, so it
should be pretty safe.
OK, sounds reasonable to me. I'll pick these up later in the week and send a pull request. Can you bring any other dependencies in via Tegra?
Yes, I was assuming that TomW would take everything else; it's all Tegra drivers.
Stephen and I are working together to get it all packaged up and in to u-boot-tegra ASAP.
Simon, any word on the u-boot-dm pull request? TomW is waiting for it before applying all the Tegra commits on top of it so he won't have to rebase, and he'd probably best send a Tegra pull request on Friday in order to make -rc2, which would be good to do. Thanks.
