Subject: [GIT PULL] csky updates for 5.6-rc3

Hi Linus,

Please pull the changes for 5.6-rc3. Sorry, I missed 5.6-rc1 merge window,
but in this pull request the most are the fixes and the rests are between
fixes and features. The only outside modification is the MAINTAINERS file
update with our mailing list.

Best Regards
 Guo Ren
