To: u-boot
v2019.01 commit cbff9f80cedd ("ARM: dts: rmobile: Sync Gen3 DTs with
Linux 4.19.6") made the sdhi/usb nodes available in r8a77965.dtsi.
Hence, remove the SDHI/USB nodes from r8a77965-u-boot.dtsi. This is
equivalent to partially reverting below v2019.01 commits:
- f529bc551b6d ("ARM: dts: rmobile: Extract USB nodes on M3N")
- 830b94f76867 ("ARM: dts: rmobile: Extract SDHI nodes on M3N")
Not doing that results in MMC devices being undetected on M3NULCB:
=> mmc list
No MMC device available

I am planning to add support for it [1], however that is work in progress and the patches still need more work. Can you rebase your changes on top of that branch and if you have M3N ULCB, test it ? The branch also contains sync with Linux 5.0 DTs, however it is also work in progress and there's likely to be breakage.

My description is not about the mainline status of M3NULCB, but rather about why the patch was sent to you. Most likely the same issue occurs on r8a77965-salvator-x{s} (which I don't have at hand), since their DTS also include r8a77965-u-boot.dtsi. Common sense tells that you should not factor out DT nodes to <soc>_u-boot.dtsi when they are properly defined and supported in <soc>.dtsi, so may I hope for a second review? > I am planning to add support for it [1], however that is work in > progress and the patches still need more work.

Unfortunately, [1] doesn't compile [2]. What I can tell you is that running rcar-3.9.3.rc1 U-Boot on M3NULCB results in: * w/o the fix: => mmc list No MMC device available * with the fix: => mmc list sd at ee100000: 0 sd at ee140000: 1 (eMMC) Your branch [1] doesn't touch arch/arm/dts/r8a77965-u-boot.dtsi, so I expect it exhibits the same issue as Renesas RC [3]. > [1] https://github.com/marex/u-boot-sh/tree/m3nulcb-v1 [2] https://gist.github.com/erosca/9d2dd0ea16fb9f208effc89226e2b27f [3] https://github.com/renesas-rcar/u-boot/tree/v2018.09/rcar-3.9.3.rc1 Thanks, Eugeniu. ^ permalink raw reply [flat|nested] 9+ messages in thread

In fact, with this patch applied, the DT for r8a77965-salvator-x is the same as without this patch. > Common sense tells that you should not factor out DT nodes to > <soc>_u-boot.dtsi when they are properly defined and supported in > <soc>.dtsi, so may I hope for a second review? I am reluctant to queue it up for this release, since we're already past RC3 and this is not fixing anything. Given that it doesn't break anything either and might improve situation for others, I'll think about queueing it up though. However, I am not happy with the commit message explanation, for one because we do not support M3N ULCB and also because this doesn't fix a bug on the M3N S-XS either, so ultimately this is a cleanup. Can you reword the commit message in such a way ? I think I know what your problem with the M3N ULCB is, the sdhiX nodes in r8a77965-u-boot.dtsi add status = "disabled" property, and in your patched U-Boot it gets somehow mixed into the final DT, so your SDHIs are actually disabled on the DT level. >> I am planning to add support for it [1], however that is work in >> progress and the patches still need more work.

[1] builds fine, but doesn't boot on my M3N-ES1.1-ULCB (no console output after exiting ATF). JFTR, my board has the following serial numbers imprinted on the PCB: - No. 20008 - RTP0RC77965SKBX010SA00 Doing some bisecting, I am able to boot the ULCB target after reverting below commits on your branch (so the issue looks PFC-related?): - 9ae6283956a6 ("pinctrl: renesas: Synchronize Gen3 tables with Linux 5.0") - 6c987dc822df ("pinctrl: renesas: Add R8A77965 pin control tables") With the above reverts, I am able to boot the target and see the MMC devices in U-Boot: => mmc list sd at ee100000: 0 sd at ee140000: 1 (eMMC) So, strictly speaking, my patch is not needed in the context of [1]. However, comparing the DT blobs before and after applying my patch to [1] using dtdiff [4], I get some interesting results (see [5]). What this tells me is that the duplicated SDHI/USB nodes from r8a77965-u-boot.dtsi are not fully in sync with r8a77965.dtsi, which can lead to all kind of obscure issues. To avoid those issues, the redundant nodes has to be removed, just as my patch does, with slight modifications in the description of the patch. > [...] > > >>> [1] https://github.com/marex/u-boot-sh/tree/m3nulcb-v1 > >> [2] https://gist.github.com/erosca/9d2dd0ea16fb9f208effc89226e2b27f > >> [3] https://github.com/renesas-rcar/u-boot/tree/v2018.09/rcar-3.9.3.rc1 [4] https://git.kernel.org/pub/scm/utils/dtc/dtc.git/tree/dtdiff [5] dtdiff r8a77965-m3nulcb-u-boot-old.dtb r8a77965-m3nulcb-u-boot-new.dtb --- /dev/fd/63 2019-03-08 14:26:43.739829001 +0100 +++ /dev/fd/62 2019-03-08 14:26:43.743829067 +0100 @@ -1425,7 +1425,7 @@ bus-width = <0x4>; cd-gpios = <0x4e 0xc 0x1>; clocks = <0x3 0x1 0x13a>; - compatible = "renesas,sdhi-r8a77965"; + compatible = "renesas,sdhi-r8a77965", "renesas,rcar-gen3-sdhi"; interrupts = <0x0 0xa5 0x4>; max-frequency = <0xc65d400>; pinctrl-0 = <0x4a>; @@ -1445,7 +1445,7 @@ sd at ee120000 { clocks = <0x3 0x1 0x139>; - compatible = "renesas,sdhi-r8a77965"; + compatible = "renesas,sdhi-r8a77965", "renesas,rcar-gen3-sdhi"; interrupts = <0x0 0xa6 0x4>; max-frequency = <0xbebc200>; power-domains = <0x1 0x20>; @@ -1457,7 +1457,7 @@ sd at ee140000 { bus-width = <0x8>; clocks = <0x3 0x1 0x138>; - compatible = "renesas,sdhi-r8a77965"; + compatible = "renesas,sdhi-r8a77965", "renesas,rcar-gen3-sdhi"; interrupts = <0x0 0xa7 0x4>; max-frequency = <0xbebc200>; mmc-hs200-1_8v; @@ -1476,7 +1476,7 @@ sd at ee160000 { clocks = <0x3 0x1 0x137>; - compatible = "renesas,sdhi-r8a77965"; + compatible = "renesas,sdhi-r8a77965", "renesas,rcar-gen3-sdhi"; interrupts = <0x0 0xa8 0x4>; max-frequency = <0xbebc200>; power-domains = <0x1 0x20>; @@ -1952,13 +1952,13 @@ usb-phy at ee080200 { #phy-cells = <0x0>; - clocks = <0x3 0x1 0x2bf>; + clocks = <0x3 0x1 0x2bf 0x3 0x1 0x2c0>; compatible = "renesas,usb2-phy-r8a77965", "renesas,rcar-gen3-usb2-phy"; interrupts = <0x0 0x6c 0x4>; phandle = <0x1b>; power-domains = <0x1 0x20>; reg = <0x0 0xee080200 0x0 0x700>; - resets = <0x3 0x2bf>; + resets = <0x3 0x2bf 0x3 0x2c0>; status = "disabled"; }; @@ -2024,7 +2024,7 @@ }; usb at ee080100 { - clocks = <0x3 0x1 0x2bf>; + clocks = <0x3 0x1 0x2bf 0x3 0x1 0x2c0>; companion = <0x47>; compatible = "generic-ehci"; interrupts = <0x0 0x6c 0x4>; @@ -2032,7 +2032,7 @@ phys = <0x1b>; power-domains = <0x1 0x20>; reg = <0x0 0xee080100 0x0 0x100>; - resets = <0x3 0x2bf>; + resets = <0x3 0x2bf 0x3 0x2c0>; status = "disabled"; }; > > [...] > -- > Best regards, > Marek Vasut Best regards, Eugeniu. ^ permalink raw reply [flat|nested] 9+ messages in thread
