Dear Community, > The btt3 device' HW revisions from 0 to 2 use imx287 SoC and are to > some extend similar to already upstreamed XEA devices, hence are > using common imx28-lwe.dtsi file. > > New, imx28-btt3.dtsi has been added to embrace common DTS > properties for different HW revisions for this device. > > As a result - changes introduced in imx28-btt3-[012].dts are > minimal. Gentle ping on this patch series... > > Signed-off-by: Lukasz Majewski <lukma@denx.de> > > --- > Changes for v2: > - Rename dts file from btt3-[012] to imx28-btt3-[012] to match current > linux kernel naming convention > - Remove 'wlf,wm8974' from compatible for codec@1a > > Changes for v3: > - Keep alphabethical order for Makefile entries > > Changes for v4: > - Change compatible for btt3 board (to 'lwn,imx28-btt3') > > Changes for v5: > - Combine patch, which adds btt3-[012] with one adding board entry to > fsl.yaml > > Changes for v6: > - Make the patch series for adding entry in fsl.yaml and btt3 > > Changes for v7: > - Use "panel" property as suggested by the community > - Use panel-timing to specify the display parameters > - Update subject line with correct tags > --- > arch/arm/boot/dts/nxp/mxs/Makefile | 3 + > arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts | 12 + > arch/arm/boot/dts/nxp/mxs/imx28-btt3-1.dts | 8 + > arch/arm/boot/dts/nxp/mxs/imx28-btt3-2.dts | 40 +++ > arch/arm/boot/dts/nxp/mxs/imx28-btt3.dtsi | 309 > +++++++++++++++++++++ 5 files changed, 372 insertions(+) > create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts > create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-1.dts > create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-2.dts > create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3.dtsi > > diff --git a/arch/arm/boot/dts/nxp/mxs/Makefile > b/arch/arm/boot/dts/nxp/mxs/Makefile index a430d04f9c69..96dd31ea19ba > 100644 --- a/arch/arm/boot/dts/nxp/mxs/Makefile > +++ b/arch/arm/boot/dts/nxp/mxs/Makefile > @@ -8,6 +8,9 @@ dtb-$(CONFIG_ARCH_MXS) += \ > imx28-apf28.dtb \ > imx28-apf28dev.dtb \ > imx28-apx4devkit.dtb \ > + imx28-btt3-0.dtb \ > + imx28-btt3-1.dtb \ > + imx28-btt3-2.dtb \ > imx28-cfa10036.dtb \ > imx28-cfa10037.dtb \ > imx28-cfa10049.dtb \ > diff --git a/arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts > b/arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts new file mode 100644 > index 000000000000..6ac46e4b21bb > --- /dev/null > +++ b/arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts > @@ -0,0 +1,12 @@ > +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT > +/* > + * Copyright 2024 > + * Lukasz Majewski, DENX Software Engineering, lukma@denx.de > + */ > + > +/dts-v1/;

The btt3 device' HW revisions from 0 to 2 use imx287 SoC and are to some extend similar to already upstreamed XEA devices, hence are using common imx28-lwe.dtsi file. New, imx28-btt3.dtsi has been added to embrace common DTS properties for different HW revisions for this device. As a result - changes introduced in imx28-btt3-[012].dts are minimal. Signed-off-by: Lukasz Majewski <lukma@denx.de> --- Changes for v2: - Rename dts file from btt3-[012] to imx28-btt3-[012] to match current linux kernel naming convention - Remove 'wlf,wm8974' from compatible for codec@1a Changes for v3: - Keep alphabethical order for Makefile entries Changes for v4: - Change compatible for btt3 board (to 'lwn,imx28-btt3') Changes for v5: - Combine patch, which adds btt3-[012] with one adding board entry to fsl.yaml Changes for v6: - Make the patch series for adding entry in fsl.yaml and btt3 Changes for v7: - Use "panel" property as suggested by the community - Use panel-timing to specify the display parameters - Update subject line with correct tags --- arch/arm/boot/dts/nxp/mxs/Makefile | 3 + arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts | 12 + arch/arm/boot/dts/nxp/mxs/imx28-btt3-1.dts | 8 + arch/arm/boot/dts/nxp/mxs/imx28-btt3-2.dts | 40 +++ arch/arm/boot/dts/nxp/mxs/imx28-btt3.dtsi | 309 +++++++++++++++++++++ 5 files changed, 372 insertions(+) create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-0.dts create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-1.dts create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3-2.dts create mode 100644 arch/arm/boot/dts/nxp/mxs/imx28-btt3.dtsi
