X-Git-Tag: v3.2-rc1~189^2^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d056f5a8fec028cc58c75706f35f2c3daed13e6e;p=platform%2Fkernel%2Flinux-exynos.git

ARM: 7026/1: simpad: replace ARM specific LED code

Remove the legacy ARM LED code for simpad devices and
register a stadard LED platform device using GPIO line
instead.
