Reviewed-by: Konrad Dybcio Signed-off-by: Praveenkumar I Signed-off-by: Varadarajan Narayanan --- v7: * Fix IO 'ranges' entry * Add root port definitions * Not adding 'dma-coherent' as the controller doesn't have that support * Remove 'bus-range' as it has default values * Group root complex related entries and root port related entries separately v6: * Add 'num-lanes' to "pcie0_phy: phy@4b0000" * Earlier, some related clock rates were set in U-Boot. In recent versions of U-Boot this has been removed resulting in the phy link not coming up. To remove boot loader dependency add assigned-clocks and assigned-clock-rates to the controller nodes. * Not sure if 'Reviewed-by' should be dropped. v5: Add 'num-lanes' to "pcie1_phy: phy@4b1000" Make ipq5332 as main and ipq9574 as fallback compatible Move controller nodes per address Having Konrad's Reviewed-By v4: Remove 'reset-names' as driver uses bulk APIs Remove 'clock-output-names' as driver uses bulk APIs Add missing reset for pcie1_phy Convert 'reg-names' to a vertical list Move 'msi-map' before interrupts v3: Fix compatible string for phy nodes Use ipq9574 as backup compatible instead of new compatible for ipq5332 Fix mixed case hex addresses Add "mhi" space Removed unnecessary comments and stray blank lines v2: Fix nodes' location per address --- arch/arm64/boot/dts/qcom/ipq5332.dtsi | 268 +++++++++++++++++++++++++- 1 file changed, 266 insertions(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/ipq5332.dtsi b/arch/arm64/boot/dts/qcom/ipq5332.dtsi index ca3da95730bd..e5c920c21974 100644 --- a/arch/arm64/boot/dts/qcom/ipq5332.dtsi +++ b/arch/arm64/boot/dts/qcom/ipq5332.dtsi @@ -186,6 +186,46 @@ rng: rng@e3000 { clock-names = "core";
