[PATCH 05/12] clocksource: samsung-time: Use local register definitions

Tomasz Figa tomasz.figa at gmail.com
Sun Feb 10 08:20:16 EST 2013


This patch copies PWM timer register definitions to samsung-time.c. The
original header in plat is being kept for now, since it is also used by
other code that also needs to be reworked to be multiplatform-friendly.
