ARM: imx: clk-vf610: enable debug access port by default
Enabled DAP (debug access port) by default. This enables the hw- breakpoint framework to make use of the breakpoints and watchpoints supported by hardware. [ 0.215805] hw-breakpoint: found 2 (+1 reserved) breakpoint and 1 watchpoint registers. [ 0.224624] hw-breakpoint: maximum watchpoint size is 4 bytes. Without this clock, the hw-breakpoint driver claims an undefined instruction during initialization: [ 0.227380] hw-breakpoint: Debug register access (0xee003e17) caused undefined instruction on CPU 0 [ 0.227519] hw-breakpoint: CPU 0 failed to disable vector catch Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
