Subject[PATCH v2 0/5] pinctrl: samsung: Data structure clean-up
Date
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

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 booted using device tree, with GPIO
leds and GPIO keyboard. Compile tested for s3c24xx, exynos, s5pv210.

Changes since v1:
- rebased on current devel branch of pinctrl tree.

Tomasz Figa (5):
pinctrl: samsung: Make samsung_pinctrl_get_soc_data use ERR_PTR()
pinctrl: samsung: Drop unused label field in samsung_pin_ctrl struct
pinctrl: samsung: Constify samsung_pin_bank_type struct
pinctrl: samsung: Constify samsung_pin_ctrl struct
pinctrl: samsung: Separate per-bank init and runtime data
