Patch Review

**Overall:** Clean, minimal device tree for the new variant. Nothing to object to.

**Makefile ordering** is correct — `bonito` sorts before `sargo` alphabetically:
```
+dtb-$(CONFIG_ARCH_QCOM)	+= sdm670-google-bonito-tianma.dtb
 dtb-$(CONFIG_ARCH_QCOM)	+= sdm670-google-sargo.dtb
```

**Compatible string** follows the standard most-specific-to-least-specific pattern:
```
+	compatible = "google,bonito-tianma", "google,bonito", "qcom,sdm670";
```

**Device-specific values** all check out against known hardware specs:
- Battery: `3700000` µAh (3700mAh, correct for Pixel 3a XL)
- Height: `2160` (matches the NT37700F panel binding description: "1080x2160 AMOLED")
- Panel compatible: `novatek,nt37700f` (binding and driver exist in-tree)
- Touchscreen: `69x137` mm (reasonable for 6.0" screen vs sargo's `62x127` mm for 5.6")

**Framebuffer region sizing:** The shared `fb_mem` reserved region is `0x2400000` (37.7 MB), which comfortably fits both sargo's 1080×2220×4 = 9.6 MB and bonito's 1080×2160×4 = 9.3 MB. No issue.

**No issues found in this patch.**
