Subject: [PATCH v2 0/3] Support for Apple SoCs' NCO blocks

Hi,

this is v2 of the common clock driver for NCO blocks on recent Apple SoCs.

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

v1: https://lore.kernel.org/linux-clk/20211214120213.15649-1-povik@protonmail.com/
