This series intends to clean up data structures used by pinctrl-samsung driver. More specifically, it separates initial compile time constants from data used at runtime, allowing unused variant data to be dropped and selected structures constified to improve safety. As a side effect, size of vmlinux built from multi_v7_defconfig was reduced from: text data bss dec hex filename 10296708 1227100 313544 11837352 b49fa8 vmlinux to: text data bss dec hex filename 10296740 1176860 313544 11787144 b3db88 vmlinux and quite a bit of data were moved from normal data sections to .init.data: pre: Idx Name Size VMA LMA File off Algn 3 .rodata 0026c080 c0881000 c0881000 00681000 2**6 23 .init.data 0003ff7c c0bdb830 c0bdb830 009e3830 2**3 24 .data..percpu 00002100 c0c1c000 c0c1c000 00a24000 2**6 25 .data 000e98e0 c0c20000 c0c20000 00a28000 2**6 post: Idx Name Size VMA LMA File off Algn 3 .rodata 0026bf20 c0881000 c0881000 00681000 2**6 23 .init.data 00041bbc c0bdb830 c0bdb830 009e3830 2**3 24 .data..percpu 00002100 c0c1e000 c0c1e000 00a26000 2**6 25 .data 000db860 c0c22000 c0c22000 00a2a000 2**6 This series should not introduce any functional changes. Tested on S3C6410-based Mini6410 board, booting with device tree. Marek, Bart, could you do some testing on Exynos-based boards, just to make sure?
