The two branches below will accept patches which sent to Linux kernel git tree, and eventually included into Linus' kernel git tree.

• fixes :
  • For collecting critical bug fixes
• for-next :
  • For accepting new features, usually it's a branch merged with clock and DT patches
  • Note: it will be forced pushed regularly!

The branch starting with 'k1/' prefix are used for individual feature or testing only, it's not a stable or permanent branch.

• k1/clk-for-6.y:
  • Collect the clock patches, will name it according to target merge version
  • The branch will be sent to clock tree for inclusion
• k1/dt-for-next: Collect the DT patches for next merge window
  • The branch will be sent to SoC tree for inclusion
• k1/*other-branch*: Experimental features just for testing only
