Neusch=C3=A4fer" The recent formalization of the fsl,gtm schema has shown that mpc8313erdb.dts doesn't provide the clock-frequency property on timer nodes. A few different expectations collide here: - Both the binding and the driver for the Freescale global timer module (GTM) have always required clock-frequency, since their addition in 2008 (v2.6.26-rc5-236-g83ff9dcf375c41). - mpc8313erdb.dts never had the timer@*/clock-frequency property, since the timer nodes were added in 2008 (v2.6.26-3343-g574366128db29e) I suspect the way this worked was that the bootloader filled these values when booting on an MPC8313 board.
