The CPU name for Exynos was concatenated with cpu id, but for new Exynos platforms, like Chromebook Peach Pi based on Exynos5800, the name of SoC variant does not include the real SoC cpu id (0x5422). For such case, the CPU name should be defined in device tree. This commit introduces new device-tree property for Exynos: - "cpu-model" - with cpu name string If defined, then the cpu id is not printed.

Exynos SoC model
|
|
|
|
The "cpu-model" property is a non-standard extension for the device tree root
|
|
node. Since the cpu id of some Exynos variants does not correspond to product
|
|
name, this property fills the gap.
|
|
|
|
For almost all Exynos based boards in the kernel, the product name corresponds
|
|
to the device tree file name. The same name is generated in U-Boot, so the new
|
|
property allows doing it automatically.
|
|
|
|
Required properties:
|
|
- cpu-model : Exynos product name
|
|
|
|
Example:
|
|
|
|
/ {
|
|
model = "Samsung/Google Peach Pi board based on Exynos5800";
|
|
cpu-model = "Exynos5800";
|
|
|
|
compatible = ...
|
|
};
