From: Stefano Radaelli <redacted> Add shared DTSI files for eMMC, NAND, Broadcom Wi-Fi and NXP IW61x options on VAR-SOM-6UL and DART-6UL. These options have the same descriptions on both modules, so use one file for each. Keep the module options independent of the carrier board so each board DTS can select its assembled storage and wireless devices. The IW61x SDIO host has no child node, so it needs no address or size cell properties. Signed-off-by: Stefano Radaelli <redacted> --- v2->v3: - Share identical eMMC, NAND, Broadcom Wi-Fi and IW61x DTSI files between the two modules. - Drop address and size cells from the IW61x SDIO host, which has no child node. .../dts/nxp/imx/imx6ul-imx6ull-var-emmc.dtsi | 32 ++++++++++ .../dts/nxp/imx/imx6ul-imx6ull-var-nand.dtsi | 63 +++++++++++++++++++ .../nxp/imx/imx6ul-imx6ull-var-wifi-brcm.dtsi | 42 +++++++++++++ .../imx/imx6ul-imx6ull-var-wifi-iw61x.dtsi | 43 +++++++++++++ 4 files changed, 180 insertions(+) create mode 100644 arch/arm/boot/dts/nxp/imx/imx6ul-imx6ull-var-emmc.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx6ul-imx6ull-var-nand.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx6ul-imx6ull-var-wifi-brcm.dtsi create mode 100644 arch/arm/boot/dts/nxp/imx/imx6ul-imx6ull-var-wifi-iw61x.dtsi
