Subject: [PATCH v3 0/3] Support for Apple SoCs' NCO blocks

Hi,

I am sending v3 of common clock driver for NCO blocks on recent Apple SoCs.

Changes since v2:

 - move all under applnco_ prefix
 - move away from signed types in register value calculations
 - other minor things from Stephen's review

Changes since v1:

 - drop apple,nchannels property from the binding, rely on size of the register
   range instead to gauge the number of channels
 - add a lock to guard set_rate from racing with clock disable/enable
 - add short "theory of operation" comment
 - incorporate minor changes from Rob's, Sven's and Stephen's review (thanks!)

Martin

v2: https://lore.kernel.org/linux-clk/20220118191839.64086-1-povik+lin@protonmail.com/
