• 42c5d52f2   clk: add helper functions clk_prepare_enable and clk_disable_unprepare ... Browse Code »

  It's for migrating to generic clk framework API.

  The helper functions help cases clk_enable/clk_disable is used
  in non-atomic context.
  For example, Call clk_enable in probe and clk_disable in remove.

• 40d3e0f49   clk: provide prepare/unprepare functions ... Browse Code »

  As discussed previously, there's the need on some platforms to run some
  parts of clk_enable() in contexts which can schedule. The solution
  which was agreed upon was to provide clk_prepare() and clk_unprepare()
  to contain this parts, while clk_enable() and clk_disable() perform
  the atomic part.

  This patch provides a common definition for clk_prepare() and
  clk_unprepare() in linux/clk.h, and provides an upgrade path for
  existing implementation and drivers: drivers can start using
  clk_prepare() and clk_unprepare() once this patch is merged without
  having to wait for platform support. Platforms can then start to
  provide these additional functions.

  Eventually, HAVE_CLK_PREPARE will be removed from the kernel, and
  everyone will have to provide these new APIs.

  This can be used for other arm platforms too as discussed
  on the linux-arm-kernel list.

  Also check the return value with IS_ERR and return PTR_ERR
  as suggested by Russell King.

  clk_get and clk_put may not be used from within interrupt context. Change
  comment to this function.
