Raspberry Pi example missing dependency linux-embedded-hal

[reeslabree]

I see this line commented out in the cargo.toml but when I add it back in cargo fails to select a version for embedded-hal.

error: failed to select a version for `embedded-hal`.
    ... required by package `linux-embedded-hal v0.4.0-alpha.1`
    ... which satisfies dependency `linux-embedded-hal = "^0.4.0-alpha.1"` of package `at-cryptoauth v0.4.1-alpha.0 (/Users/reeslabree/Documents/etc/at-cryptoauth-rs)`
versions that meet the requirements `=1.0.0-alpha.5` are: 1.0.0-alpha.5

all possible versions conflict with previously selected packages.

  previously selected package `embedded-hal v1.0.0-alpha.9`
    ... which satisfies dependency `embedded-hal = "=1.0.0-alpha.9"` of package `at-cryptoauth v0.4.1-alpha.0 (/Users/reeslabree/Documents/etc/at-cryptoauth-rs)`

What is the proper version of linux-embedded-hal to use? I'm compiling using cross with:
cross build --target armv7-unknown-linux-gnueabihf --example raspberrypi_atecc608 --features std.
