This provides an example of how to use the Tegra CAR clock binding in a board .dts file.
Signed-off-by: Stephen Warren swarren@nvidia.com --- I think it makes sense to check the previous patch into the Linux kernel, since it's mainly just defining what the binding is. However, this patch is just an example and needs to be reworked to cover all boards, and add a PMU node for the true clk_32k source. I'm providing this patch mostly as an example that Simon Glass can use within U-Boot in the interim. --- arch/arm/boot/dts/tegra-seaboard.dts | 24 ++++++++++++++++++++++++ 1 files changed, 24 insertions(+), 0 deletions(-)
