This enables LDO bypass by default on the imx6qdl-sabresd boards. New dts files with -ldo suffix are added for users who want to run with LDOs enabled on these boards anyway.
Given that using LDO bypass affects the device lifetime negatively (see AN4724), I think the default should still be to use LDO enabled mode and have new DTs for people that desire to shorten the lifetime of the SoC for a minimal drop in power consumption.
This was based on what the Freescale BSP does, I don't particularly object to upstream having a different default. It would be nice for testing if this ldo-bypass path was enabled by default for some boards but it's not a very good reason. I will switch the default. --? Regards, Leonard
