Subject: [PATCH 15/22] ARM: at91rm9200 timer: Make system timer defines SoC specific
Date: Mon, 5 Nov 2018 16:51:06 +0100 [thread overview]
Message-ID: <20181105155113.3434-16-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20181105155113.3434-1-s.hauer@pengutronix.de>
- rename at91_st.h to at91rm9200_st.h
- rename prefix from AT91_ to AT91RM9200_
- remove register offset from System timer defines
