      dt-bindings: clk: at91: add audio plls to the compatible list · 33202fa3
      由 Quentin Schulz 提交于 
      This new clock driver set allows to have a fractional divided clock that
would generate a precise clock particularly suitable for audio
applications.

The main audio pll clock has two children clocks: one that is connected
to the PMC, the other that can directly drive a pad. As these two routes
have different enable bits and different dividers and divider formulas,
they are handled by two different drivers.

This adds the audio plls (frac, pad and pmc) to the compatible list of
at91 clocks in DT binding.

      clk: at91: clk-generated: remove useless divisor loop · 8c7aa632
      由 Quentin Schulz 提交于 
      The driver requests the current clk rate of each of its parent clocks to
decide whether a clock rate is suitable or not. It does not request
determine_rate from a parent clock which could request a rate change in
parent clock (i.e. there is no parent rate propagation).

We know the rate we want (passed along req argument of the function) and
the parent clock rate, thus we know the closest rounded divisor, we
don't need to iterate over the available divisors to find the best one
for a given clock.

      clk: mb86s7x: Drop non-building driver · 8bb48f79
      由 Andreas Färber 提交于 
      It fails to build once we introduce the ARCH_MB86S7X Kconfig symbol:

  compilation terminated.

And when commenting out that line, we get:
