2023-05-24arm64: dts: imx8mp: add bus_early clock to imx8mp-dwc3Stefan Eichenberger
Add a bus_early clock property to the imx8mp-dwc3 driver so that we can access register 0x382f0000 and 0x381f0000 after a suspend/resume cycle. Without this change suspend/resume will hang on resume. Upstream-Status: Inappropriate [other] This fix is only needed for the downstream kernel. In the upstream kernel they added a power-domain for all hsio devices (usb, pcie, etc.) and enable the clock there. However, backporting this solution would probably cause more issues for now. Fixes: cbd09f688623 ("usb: dwc3: imx8mp: Add support for setting SOC specific flags") Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com>
2023-04-28toradex_imx_v8.config: compile the i.MX SATA driver as moduleStefan Eichenberger
There are situations when PCIe probes after SATA so that Wifi does not come up. By compiling the SATA driver as a module we workaround this issue. Upstream-Status: Inappropriate [Configuration] Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com>
2023-04-26arm64: dts: imx8-apalis: use startup-delay-us for wifi regulatorStefan Eichenberger
We used regulator-settling-time-us for the wifi regulator which is wrong for regulator-fixed. We have to use startup-delay-us instead. Upstream-Status: Pending Mainline for i.MX 8 does not support PCIe yet, this patch cannot be upstreamed as of now. Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com>
2023-04-26arm64: dts: imx8-apalis: rename wifi regulatorStefan Eichenberger
Rename the wifi regulator to what is the net name in the schematic. Upstream-Status: Pending Mainline for i.MX 8 does not support PCIe yet, this patch cannot be upstreamed as of now. Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com>
2023-04-26arm64: dts: colibri-imx8x: use clock and regulator instead of gpio hogsStefan Eichenberger
Replace gpio-hogs by using the hsio clock to enable the PCIe reference clock for Wifi and vcie-supply to power on the Wifi module. With this change the gpios will not be touched when Wifi is disabled. Upstream-Status: Pending Mainline for i.MX 8X does not support PCIe yet, this patch cannot be upstreamed as of now.

2023-04-21arm64: dts: imx8-apalis: remove redundant clocks from pcie and sataStefan Eichenberger
We set the same pcie and sata clock as the include files. This commit removes redundancy. Upstream-Status: Pending Mainline for i.MX 8 does not support PCIe yet, this patch cannot be upstreamed as of now. Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com>
2023-04-21arm64: dts: imx8-apalis: pcieb use vpcie-supply instead of epdevStefan Eichenberger
Use the vpcie-supply property instead of epdev_on-supply. This property is also available in the upstream bsp and is therefore preferred. Upstream-Status: Pending Mainline for i.MX 8 does not support PCIe yet, this patch cannot be upstreamed as of now. Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com>
2023-04-21arm64: dts: imx8-apalis: use the hsio clocks for pcie and sataStefan Eichenberger
Use the hsio clocks for pcie and sata as NXP does in their device tree. We can therefore remove the pcie_ext and sata_ext properties and don't have to add any special properties. Upstream-Status: Pending Mainline for i.MX 8 does not support PCIe yet, this patch cannot be upstreamed as of now. Signed-off-by: Stefan Eichenberger <stefan.eichenberger@toradex.com>
2023-04-21arm64: dts: imx8-apalis: set correct gpios for hsio clocksStefan Eichenberger
Set the correct gpios for the hsio clocks. This will allow us to use the predefined hsio clocks from NXP to enable the pcie and sata clocks.

i.MX8, i.MX8X, i.MX8XP and i.MX8XL SOC device trees are all based on imx8-ss-*.dtsi files. For i.MX8X and i.MX8XP these device trees should be updated with some peripherals removed or updated, similar to i.MX8XL (imx8dxl-ss-*.dtsi files). However, it looks like only i.MX8 and i.MX8XL are up to date, but for i.MX8X and i.MX8XP some of the peripherals got inherited from imx8-ss-*.dtsi files, but in reality they are not present on SOC. As a result, during resource partition ownership check U-Boot receives messages from SCU firmware about these resources not owned by boot partition. In reality, these resources are not owned by anyone, as they simply does not exist, but are defined in Linux device tree.
