Generally speaking, if you only have small updates (a few patches at a time), feel free to send those patches to soc@xxxxxxxxxx once you consider them ready for inclusion. On 32-bit architectures as well as the more widely used 64-bit platforms with many .dts files, please send pull requests that group the patches into logical topics. Once you are listed in the MAINTAINERS file and you want to host a git tree on git.kernel.org for that purpose, you can apply for a kernel.org account and send pull request from there as well as have the tree integrated into linux-next for earlier testing. On the more specialized platforms without third-party machine support in the kernel, that is usually not necessary. In either case, patches and pull requests should be based on an early -rc tag from mainline Linux (normally -rc1) and get sent between -rc1 and roughly -rc5 for new features. Bug fixes can be sent at any time regardless of the current -rc, with a balance between sending them quickly and collecting multiple of them into a pull request to reduce the number of merges. Please let us know whether bug fixes should be applied only at the next merge window, on current kernels, or backported to previous releases, using the "Fixes:" and "Cc: stable@xxxxxxxxxxxxxxx" tags as appropriate. The default is to backport bug fixes as far back as they apply, unless there is a reason not to. Arnd
