From mboxrd@z Thu Jan 1 00:00:00 1970 From: dinguyen@altera.com (dinguyen at altera.com) Date: Wed, 24 Jul 2013 22:43:16 -0500 Subject: [PATCH 1/2] ARM: dts: Change dw-apb-timer-osc and dw-apb-timer-sp to just dw-apb-timer Message-ID: <1374723797-22169-1-git-send-email-dinguyen@altera.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Dinh Nguyen "dw-apb-timer-osc" and "dw-apb-timer-sp" are the same implementation of the DW APB timer, just fed by different clocks.
