[PATCH v4 0/3] Support for Apple SoCs' NCO blocks

[Martin Povišer]

Hello,

This is v4 of common clock driver for NCO blocks on Apple SoCs. I have to send v4
because to some people I inadvertently send their copy of v3 PGP-encrypted.

Changes since v3:

 - change my email address
 - set MODULE_LICENSE to 'GPL' (was 'GPL v2')

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
