I briefly looked at the contents and noticed that the PCIe host node you add has a dma-ranges property, but its parent node does not, so you are still limited to 32-bit DMA and you should fix that.

Hi Olof, Hi Kevin, Hi Arnd, Please consider these second round of Renesas ARM64 based SoC DT updates for v4.7. This pull request is based on the previous round of such requests, tagged as renesas-arm64-dt-for-v4.7, which I have already sent a pull-request for. The following changes since commit 81ae0ac31bb90baef10850fdfdc2a9f72f36aa6f: arm64: dts: r8a7795: Use USB3.0 fallback compatibility string (2016-03-28 08:52:47 +0900) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git tags/renesas-arm64-dt2-for-v4.7 for you to fetch changes up to 9f33a8a9e1b7dbb0b91a58af958d1c301a6fab1a: arm64: dts: r8a7795: Don't disable referenced optional clocks (2016-04-27 11:48:34 +1000) ---------------------------------------------------------------- Second Round of Renesas ARM64 Based SoC DT Updates for v4.7 * Don't disable referenced optional clocks in DT of r8a7795 SoC * Populate EXTALR in DT of salvator-x board * Enable PCIe in DT of salvator-x board ---------------------------------------------------------------- Geert Uytterhoeven (1): arm64: dts: r8a7795: Don't disable referenced optional clocks Phil Edworthy (2): arm64: dts: r8a7795: Add PCIe nodes arm64: dts: r8a7795: enable PCIe on Salvator-X Wolfram Sang (1): arm64: dts: salvator-x: populate EXTALR arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts | 17 +++++++ arch/arm64/boot/dts/renesas/r8a7795.dtsi | 58 +++++++++++++++++++++- 2 files changed, 73 insertions(+), 2 deletions(-)
