[PATCH 3/5] media: rkisp1: Simplify LSC x/y size and grad register macros

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

 



The LSC module x/y size and grad configuration is stored in a set of 4
indexed registers each. The rkisp1-regs.h header defines all those
registers, but only the first one in each set is used, with manual
calculation of addresses of subsequent registers. Simplifies this by
merging all 4 register macros into one that takes the index as a
parameter. No functional change intended.
