Revert "of: match by compatible property first"

2012-07-10T19:49:32Z

This reverts commit 107a84e61cdd3406c842a0e4be7efffd3a05dba6. Meelis Roos reports a regression since 3.5-rc5 that stops Sun Fire V100 and Sun Netra X1 sparc64 machines from booting, hanging after enabling serial console. He bisected it to commit 107a84e61cdd. Rob Herring explains: "The problem is match combinations of compatible plus name and/or type fail to match correctly. I have a fix for this, but given how late it is for 3.5 I think it is best to revert this for now. There could be other cases that rely on the current although wrong behavior. I will post an updated version for 3.6." Bisected-and-reported-by: Meelis Roos Requested-by: Rob Herring Cc: Thierry Reding Cc: Grant Likely Signed-off-by: Linus Torvalds

of: address: Don't fail a lookup just because a node has no reg property

2012-07-06T19:42:10Z

Sometimes it doesn't make any sense for a node to have an address. In this case device lookup will always be unsuccessful because we currently assume every node will have a reg property. This patch changes the semantics so that the resource address and the lookup address will only be compared if one exists. Things like AUXDATA() rely on of_dev_lookup to return the lookup entry of a particular device in order to do things like apply platform_data to a device. However, this is currently broken for nodes which do not have a reg property, meaning that platform_data can not be passed in those cases.

of: match by compatible property first

2012-06-15T01:29:40Z

When matching devices against an OF device ID table, the first string of the compatible property that is listed in the table should match, regardless of its position in the table.

Pull MIPS updates from Ralf Baechle: "The whole series has been sitting in -next for quite a while with no complaints. The last change to the series was before the weekend the removal of an SPI patch which Grant - even though previously acked by himself - appeared to raise objections. So I removed it until the situation is clarified. Other than that all the patches have the acks from their respective maintainers, all MIPS and x86 defconfigs are building fine and I'm not aware of any problems introduced by this series. Among the key features for this patch series is a sizable patchset for Lantiq which among other things introduces support for Lantiq's flagship product, the FALCON SOC. It also means that the opensource developers behind this patchset have overtaken Lantiq's competing inhouse development team that was working behind closed doors. Less noteworthy the ath79 patchset which adds support for a few more chip variants, cleanups and fixes. Finally the usual dose of tweaking of generic code." Fix up trivial conflicts in arch/mips/lantiq/xway/gpio_{ebu,stp}.c where printk spelling fixes clashed with file move and eventual removal of the printk. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (81 commits) MIPS: lantiq: remove orphaned code MIPS: Remove all -Wall and almost all -Werror usage from arch/mips.

Pull i2c-embedded changes from Wolfram Sang: "Major changes: - lots of devicetree additions for existing drivers. I tried hard to make sure the bindings are proper. In more complicated cases, I requested acks from people having more experience with them than me. That took a bit of extra time and also some time went into discussions with developers about what bindings are and what not. I have the feeling that the workflow with bindings should be improved to scale better. I will spend some more thought on this... - i2c-muxes are succesfully used meanwhile, so we dropped EXPERIMENTAL for them and renamed the drivers to a standard pattern to match the rest of the subsystem. They can also be used with devicetree now. - ixp2000 was removed since the whole platform goes away. - cleanups (strlcpy instead of strcpy, NULL instead of 0) - The rest is typical driver fixes I assume. All patches have been in linux-next at least since v3.4-rc6."

Pull device tree conversions for arm-soc, part 1, from Olof Johansson: "The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of booting using device trees, which is a great step forward for them. at91 and spear have pretty much completed this process with a huge amount of work being put into at91.
