.gitattributes: set git diff driver for C source code files Git can be told to apply language-specific rules when generating diffs. Enable this for C source code files (.c and .h) so that function names are printed right. Specifically, doing so prevents "git diff" from mistakenly considering unindented goto labels as function names.

.gitattributes: use 'dts' diff driver for dts files Git is gaining support to display the closest node to the diff in the hunk header via the 'dts' diff driver. Use that driver for all dts and dtsi files so we can gain some more context on where the diff is. Taking a recent commit in the kernel dts files you can see the difference. With this patch and an updated git : diff --git a/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi b/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi : index 62e07e1197cc..4c38426a6969 100644 : --- a/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi : +++ b/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi : @@ -289,5 +289,29 @@ vdd_hdmi: regulator@1 { : gpio = <&gpio TEGRA194_MAIN_GPIO(A, 3) GPIO_ACTIVE_HIGH>; : enable-active-high; : }; : + : + vdd_3v3_pcie: regulator@2 { : + compatible = "regulator-fixed"; vs. without this patch : diff --git a/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi b/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi : index 62e07e1197cc..4c38426a6969 100644 : --- a/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi : +++ b/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi : @@ -289,5 +289,29 @@ : gpio = <&gpio TEGRA194_MAIN_GPIO(A, 3) GPIO_ACTIVE_HIGH>; : enable-active-high; : }; : + : + vdd_3v3_pcie: regulator@2 { : + compatible = "regulator-fixed"; You can see that we don't know what the context node is because it isn't shown after the '@@'. dts is not released yet but it is staged to be in the next release[1]. One can probably build git from source and try it out.
