There are 2 revisions of the Exynos5250 Snow Chromebook that were shipped:
Rev4 and Rev5. The only difference between these 2 revisions is the codec,
Rev4 has a max98095 codec while Rev5 has a max98090.
Mainline only supports Rev4 so this patch moves the common device nodes to
a DTSI file and adds a DTS for the Exynos5250 Snow Rev5.
The Snow Rev5 DTS is based on the DTS found in the ChromiumOS 3.8 tree.
Signed-off-by: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx>
---
The DTS in the vendor ChromeOS tree are called exynos5250-snow-rev{4,5}.dtb
but I decided to leave Rev4 as exynos5250-snow.dtb to avoid breaking u-boot
that has CONFIG_DEFAULT_DEVICE_TREE="exynos5250-snow" in snow_defconfig.
Also, ChromiumOS Rev4 DTS has "google,snow-rev4" in its compatible string
but was not added in mainline since Rev4 firmware fallbacks to "google,snow"
and Rev5 searches for "google,snow-rev5". That way the compatible string
could be consistent with the DTS naming and still be able to pack both Rev4
and Rev5 FDT in the same FIT image and let the firmware pick the correct FDT.
