One can list all the .dts files in a directory and convert those to %.dtb targets, but that doesn't work for base+overlay DTB targets. Adding the dts subdirectory is straight-forward, but building the DTBs should only happen for certain targets (dtbs, dtbs_check, %.dtb, %.dtbo, and the directory target(s)). The 'scripts_dtc' rule doesn't really depend on 'dt_binding_schemas', but the directory target only depends on 'scripts' which depends on 'scripts_dtc'. Signed-off-by: Rob Herring (Arm) --- Please ack and I'll take this in the DT tree. I don't really like looking at MAKECMDGOALS, but that's the only way I could come up with that works. Maybe someone knows a better way. v2: - Convert arm, mips and riscv. The other DT enabled arches don't have vendor directories. - Link to v1: https://lore.kernel.org/all/20251113225952.867138-1-robh@kernel.org/ --- Makefile | 2 +- arch/arm/Kbuild | 2 ++ arch/arm64/Kbuild | 2 ++ arch/mips/Kbuild | 2 ++ arch/riscv/Kbuild | 2 ++ scripts/Makefile.dtbs | 3 +++ 6 files changed, 12 insertions(+), 1 deletion(-) diff --git a/Makefile b/Makefile index 17cfa11ca716..85018d461575 100644 --- a/Makefile +++ b/Makefile @@ -1494,7 +1494,7 @@ export CHECK_DTBS=y endif ifneq ($(CHECK_DTBS),) -dtbs_prepare: dt_binding_schemas +scripts_dtc: dt_binding_schemas endif dtbs_check: dtbs diff --git a/arch/arm/Kbuild b/arch/arm/Kbuild index 69de6b6243c7..af7dd53585c3 100644 --- a/arch/arm/Kbuild +++ b/arch/arm/Kbuild @@ -10,5 +10,7 @@ obj-y += probes/ obj-y += net/ obj-y += crypto/ +subdir-y += boot/dts + # for cleaning subdir- += boot diff --git a/arch/arm64/Kbuild b/arch/arm64/Kbuild index 5bfbf7d79c99..9e9820af48c9 100644 --- a/arch/arm64/Kbuild +++ b/arch/arm64/Kbuild @@ -5,5 +5,7 @@ obj-$(CONFIG_XEN) += xen/ obj-$(subst m,y,$(CONFIG_HYPERV)) += hyperv/ obj-$(CONFIG_CRYPTO) += crypto/ +subdir-y += boot/dts + # for cleaning subdir- += boot diff --git a/arch/mips/Kbuild b/arch/mips/Kbuild index e901bf554483..6125d00cdcef 100644 --- a/arch/mips/Kbuild +++ b/arch/mips/Kbuild @@ -21,5 +21,7 @@ ifdef CONFIG_KVM obj-y += kvm/ endif +subdir-y += boot/dts + # for cleaning subdir- += boot diff --git a/arch/riscv/Kbuild b/arch/riscv/Kbuild index 126fb738fc44..3cf7f84eb287 100644 --- a/arch/riscv/Kbuild +++ b/arch/riscv/Kbuild @@ -7,5 +7,7 @@ obj-$(CONFIG_KVM) += kvm/ obj-$(CONFIG_ARCH_SUPPORTS_KEXEC_PURGATORY) += purgatory/ +subdir-y += boot/dts + # for cleaning subdir- += boot diff --git a/scripts/Makefile.dtbs b/scripts/Makefile.dtbs index 2d321b813600..4d0d164df275 100644 --- a/scripts/Makefile.dtbs +++ b/scripts/Makefile.dtbs @@ -14,7 +14,10 @@ dtb-y := $(addprefix $(obj)/, $(dtb-y)) multi-dtb-y := $(addprefix $(obj)/, $(multi-dtb-y)) real-dtb-y := $(addprefix $(obj)/, $(real-dtb-y)) +ifneq ($(findstring /dts/,$(MAKECMDGOALS))$(findstring dtb,$(MAKECMDGOALS)),) always-y += $(dtb-y) +endif + targets += $(real-dtb-y) # dtbs-list -- 2.51.0
