      clk: si570: Add a driver for SI570 oscillators · 1459c837
      Soren Brinkmann authored
      Add a driver for SILabs 570, 571, 598, 599 programmable oscillators.
      The devices generate low-jitter clock signals and are reprogrammable via
      an I2C interface.

      clk: Fix debugfs reparenting NULL pointer dereference · 3a5aec24
      Stephen Boyd authored
      Adding clocks from a kernel module can cause a NULL pointer
      dereference if the parent of a clock is added after the clock is
      added. This happens because __clk_init() iterates over the list
      of orphans and reparents the orphans to the clock being
      registered before creating the debugfs entry for the clock.
      Create the debugfs entry first before reparenting the orphans.
      Unable to handle kernel NULL pointer dereference at virtual address 00000028
