[PATCH 20/20] of: deprecate and rename of_property_for_each_u32()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



of_property_for_each_u32() is meant to disappear. All the call sites not
using the 3rd and 4th arguments have already been replaced by
of_property_for_each_u32_new().

Deprecate the old macro. Also rename it to minimize the number of new
usages and encourage conversion to the of_property_for_each_u32_new() macro
in not(-yet)-upstream code.

Notes:

 * The following files have not been build-tested simply because I haven't
   managed to have a config that enables them so far:

     drivers/irqchip/irq-pic32-evic.c
     drivers/pinctrl/pinctrl-k210.c

 * These have not been converted yet as they are not trivial, and they will
   need to use a more specific function that does the lookup they need and
   returns the result:

     drivers/clk/clk-si5351.c
     drivers/clk/clk.c
