Thanks for doing that. I actually learned a bit. :-) This may be more directed at Simon, but it seems like many platforms are limited in SPL and OF_PLATDATA might be a great feature to get more drivers supporting device tree booting without as much overhead. From how the documentation reads, it seems like the drivers may not necessarily support OF_PLATDATA by default. I've been struggling trying to enable basic functions (like serial via 16550 driver) because the platform data generated doesn't necessarily match the platform data I use to start the serial device. I would like to migrate from using manually entered platform data to using OF_PLATDATA to reduce the overhead. A few things I noticed are that the generated device names correspond to the names listed in the 'compatible' flag and there doesn't seem to be a good way to link them to the actual driver name. I see a few drivers that check for OF_PLATDATA, but I am not seeing many people actually utilize this feature. Any suggestions on how to one might migrate a driver (like serial) which already supports OF_CONTROL in u-boot, but the generated platdata doesn't boot in SPL? adam > > > > Signed-off-by: Simon Goldschmidt <[email protected]> > > --- > > > > Changes in v2: > > - further fixes noted by Simon Glass > > - added info about missing node relations > > - moved the passage about phandles into section 'caveats' > > > > doc/driver-model/of-plat.txt | 31 ++++++++++++++++++++----------- > > dts/Kconfig | 6 ++---- > > 2 files changed, 22 insertions(+), 15 deletions(-) > > Reviewed-by: Simon Glass <[email protected]> > > Applied to u-boot-dm, thanks! > _______________________________________________ > U-Boot mailing list > [email protected] > https://lists.denx.de/listinfo/u-boot _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
