+This get/lookup/select/put sequence can just as well be handled by bus drivers
 if you don't want each and every driver to handle it and you know the

-The semantics of the get/enable respective disable/put is as follows:
+The semantics of the pinctrl APIs are:
 
-- pinctrl_get() is called in process context to reserve the pins affected with
-  a certain mapping and set up the pinmux core and the driver. It will allocate
-  a struct from the kernel memory to hold the pinmux state.
+- pinctrl_get() is called in process context to obtain a handle to all pinctrl
+  information for a given client device. It will allocate a struct from the
+  kernel memory to hold the pinmux state. All mapping table parsing or similar
+  slow operations take place within this API.
 
-- pinctrl_enable()/pinctrl_disable() is quick and can be called from fastpath
-  (irq context) when you quickly want to set up/tear down the hardware muxing
-  when running a device driver. Usually it will just poke some values into a
-  register.
+- pinctrl_lookup_state() is called in process context to obtain a handle to a
+  specific state for a the client device. This operation may be slow too.
 
-- pinctrl_disable() is called in process context to tear down the pin requests
-  and release the state holder struct for the mux setting etc.
+- pinctrl_select_state() programs pin controller hardware according to the
+  definition of the state as given by the mapping table. In theory this is a
+  fast-path operation, since it only involved blasting some register settings
+  into hardware. However, note that some pin controllers may have their
+  registers on a slow/IRQ-based bus, so client devices should not assume they
+  can call pinctrl_select_state() from non-blocking contexts.

+- pinctrl_put() frees all information associated with a pinctrl handle.
