Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The patch adds the `samsung,exynos5515-chipid` compatible string with a fallback to `samsung,exynos850-chipid`, but omits the necessary driver update to support the new SoC. The `exynos-chipid` driver enforces a strict hardware whitelist based on the product ID and will return `-ENODEV` during probe when it encounters the unknown Exynos 5515 ID, rendering the fallback useless.

Author: Aiden Isik <aidenisik@member.fsf.org>
Subject: dt-bindings: hwinfo: samsung,exynos-chipid: Add Exynos5515 compatible
This commit adds the samsung,exynos5515-chipid compatible string to the
exynos-chipid device tree bindings documentation.

[Severity: Medium]
Will this compatible string actually allow the driver to probe on Exynos 5515
hardware?
Even with a fallback to samsung,exynos850-chipid, the exynos-chipid driver
enforces a strict hardware whitelist based on the product ID:
drivers/soc/samsung/exynos-chipid.c:exynos_chipid_probe() {
...
soc_dev_attr->soc_id = exynos_product_id_to_name(soc_info.product_id);
if (!soc_dev_attr->soc_id)
return dev_err_probe(dev, -ENODEV, "Unknown SoC\n");
...
}
Does this require a corresponding driver update to add the Exynos 5515 product
ID to the whitelist so the probe does not fail with -ENODEV?
