Subject: [PATCH 0/3] clk: let clock perform allocation in init

This patchset is a follow up on this pinky swear [0].
Its purpose is:
 * Clarify the acceptable use of clk_ops init() callback
 * Let the init() callback return an error code in case anything
   fail.
 * Add the terminate() counter part of of init() to release the
   resources which may have been claimed in init()

After discussing with Stephen at LPC, I decided to drop the 2 last patches
of the RFC [1]. I can live without it for now and nobody expressed a
critical need to get the proposed placeholder.

Jerome Brunet (3):
  clk: actually call the clock init before any other callback of the
    clock
  clk: let init callback return an error code
  clk: add terminate callback to clk_ops
