Refactor the MSM8916 and MSM8939 device trees to make use of dynamic memory reservations for the firmware regions, rather than hardcoding fixed addresses for each device. This allows to keep most of the definitions in the SoC.dtsi while defining the board-specific properties (such as firmware size) separately for each device. The main motivation for this patch set is to simplify enabling the modem on the various MSM8916/39 devices. The modem firmware size differs on almost each device, which requires redefining *all* of the firmware reservations with newly calculated addresses to make room for the larger modem firmware. I've explained this in detail in a previous RFC: https://lore.kernel.org/linux-arm-msm/20230510-dt-resv-bottom-up-v1-4-3bf68873dbed@xxxxxxxxxxx/ Signed-off-by: Stephan Gerhold <stephan@xxxxxxxxxxx> --- Stephan Gerhold (9): arm64: dts: qcom: msm8916: Disable venus by default arm64: dts: qcom: msm8916/39: Disable GPU by default arm64: dts: qcom: msm8916-ufi: Drop gps_mem for now arm64: dts: qcom: msm8916: Reserve firmware memory dynamically arm64: dts: qcom: msm8916: Reserve MBA memory dynamically arm64: dts: qcom: msm8939: Reserve firmware memory dynamically arm64: dts: qcom: msm8916/39: Disable unneeded firmware reservations arm64: dts: qcom: msm8916/39: Move mpss_mem size to boards arm64: dts: qcom: msm8916/39: Fix venus memory size arch/arm64/boot/dts/qcom/apq8016-sbc.dts | 25 ++++++++++++++ arch/arm64/boot/dts/qcom/apq8039-t2.dts | 8 +++++ arch/arm64/boot/dts/qcom/msm8916-acer-a1-724.dts | 12 +++++++ .../boot/dts/qcom/msm8916-alcatel-idol347.dts | 12 +++++++ arch/arm64/boot/dts/qcom/msm8916-asus-z00l.dts | 12 +++++++ arch/arm64/boot/dts/qcom/msm8916-gplus-fl8005a.dts | 12 +++++++ arch/arm64/boot/dts/qcom/msm8916-huawei-g7.dts | 12 +++++++ .../boot/dts/qcom/msm8916-longcheer-l8150.dts | 21 ++++++++++-- .../boot/dts/qcom/msm8916-longcheer-l8910.dts | 12 +++++++ .../dts/qcom/msm8916-samsung-a2015-common.dtsi | 12 +++++++ .../boot/dts/qcom/msm8916-samsung-a3u-eur.dts | 4 +++ .../boot/dts/qcom/msm8916-samsung-a5u-eur.dts | 4 +++ .../dts/qcom/msm8916-samsung-e2015-common.dtsi | 4 +++ .../boot/dts/qcom/msm8916-samsung-gt5-common.dtsi | 12 +++++++ .../boot/dts/qcom/msm8916-samsung-j5-common.dtsi | 12 +++++++ .../boot/dts/qcom/msm8916-samsung-serranove.dts | 12 +++++++ arch/arm64/boot/dts/qcom/msm8916-ufi.dtsi | 33 +++++++++++------- .../boot/dts/qcom/msm8916-wingtech-wt88047.dts | 12 +++++++ arch/arm64/boot/dts/qcom/msm8916.dtsi | 39 +++++++++++++++++----- arch/arm64/boot/dts/qcom/msm8939-samsung-a7.dts | 4 +++ .../dts/qcom/msm8939-sony-xperia-kanuti-tulip.dts | 8 +++++ arch/arm64/boot/dts/qcom/msm8939.dtsi | 37 +++++++++++++++----- 22 files changed, 288 insertions(+), 31 deletions(-) --- base-commit: 0bb80ecc33a8fb5a682236443c1e740d5c917d1d change-id: 20230720-msm8916-rmem-f88fff6bcded Best regards, -- Stephan Gerhold <stephan@xxxxxxxxxxx>
