Add the new herobrine-r1. Note that this is pretty much a re-design compared to herobrine-r0 so we don't attempt any dtsi to share stuff between them. This patch attempts to define things at 3 levels: 1. The Qcard level. Herobrine includes a Qcard PCB and the Qcard PCB is supposed to be the same (modulo stuffing options) across multiple boards, so trying to define what's there hopefully makes sense. NOTE that newer "CRD" boards from Qualcomm also use Qcard. When support for CRD3 is added hopefully it can use the Qcard include (and perhaps we should even evaluate it using herobrine.dtsi?) 2. The herobrine "baseboard" level. Right now most stuff is here with the exception of things that we _know_ will be different per board. We know that not all boards will have the same set of eMMC, nvme, and SD. We also know that the exact pin names are likely to be different. 3. The actual "board" level, AKA herobrine-rev1. NOTES: - This boots to command prompt. We're still waiting on the PWM driver. - This assumes LTE for now. Once it's clear how WiFi-only SKUs will work we expect some small changes. Signed-off-by: Douglas Anderson <dianders@chromium.org> --- Removed Reviewed-by tags in v3 since it felt like there were enough changes that people should re-confirm that they're happy. Changes in v3: - Rebased atop dts cleanup patches. - Add regulator suffix as per dts cleanup patches. - Set PCIe bias / pull as per dts cleanup patches. - Add dp_hot_plug_det pull as per dts cleanup patches. - Setup SD card same as dts cleanup patches. Changes in v2: - Herobrine compatible on one line, not two - Wording change in comments for components enabled per-board - Always sort "bias" above "drive-strength" in pinctrl. - Properly sort "hub_en" pinctrl. - Two comments moved from multiline to single line. - Space after "/delete-property/" arch/arm64/boot/dts/qcom/Makefile | 1 + .../qcom/sc7280-herobrine-herobrine-r0.dts | 3 +- .../qcom/sc7280-herobrine-herobrine-r1.dts | 313 +++++++ .../arm64/boot/dts/qcom/sc7280-herobrine.dtsi | 785 ++++++++++++++++++ arch/arm64/boot/dts/qcom/sc7280-qcard.dtsi | 547 ++++++++++++ 5 files changed, 1647 insertions(+), 2 deletions(-) create mode 100644 arch/arm64/boot/dts/qcom/sc7280-herobrine-herobrine-r1.dts create mode 100644 arch/arm64/boot/dts/qcom/sc7280-herobrine.dtsi create mode 100644 arch/arm64/boot/dts/qcom/sc7280-qcard.dtsi
