dm: core: Read parent ofdata before children 2020-04-16T14:07:58+00:00 Simon Glass sjg@chromium.org 2020-04-05T21:38:19+00:00 b0dcc87106464c3fc019e3771378a092fd32ebdb At present a device can read its ofdata before its parent has done the same. This can cause problems in the case where the parent has a 'ranges' property, thus affecting the operation of dev_read_addr(), for example. We already probe parent devices before children so it does not seem to be a large step to do the same with ofdata. Make the change and update the documentation in this area.

sandbox: Update PCI nodes in dts files 2020-04-16T14:07:57+00:00 Tom Rini trini@konsulko.com 2020-02-11T17:41:23+00:00 42c64d1bc9d5d3c68f14b872ab71ec7d5fe97cbc The way the PCI nodes are written today causes a number of warnings if we stop disabling some of the warnings we pass to DTC. As these warnings aren't disabled in current Linux Kernel builds, we should aim to not disable them here either, so rewrite these slightly. Update the driver model doc as well.

This is particularly sad as proper documentation would help in porting drivers over to the driver model. Rewrite the document to describe network drivers in the new driver model world. Most driver callbacks/methods are almost identical in their semantic, but recv() differs in some important details. Also keep some parts of the original text at the end, to help understanding old drivers. Add some hints on how to port drivers over. This also uses the opportunity to reformat the document in reST, on the way moving it into doc/driver-model and adding it into the structure there.
