* ARM: dts: Move .dts files to vendor sub-directoriesRob Herring2023-06-211-92/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.

* ARM: dts: BCM5301X: Describe switch ports in the main DTSRafał Miłecki2023-06-091-3/+0
| | | | | | | | | | | | | | | | | | | | All Northstar SoCs have BCM5301x switches (BCM53011, BCM53012) with 8 ports (0-8 without 6). By design 3 switch ports (5, 7 and 8) are hardwired to 3 on-SoC Ethernet interfaces. Switch port 8 requires forcing link state. It seems that global Northstar .dtsi file is the best place to describe those hw details. Only device specific bits (like labels) should go to device .dts files. This seems to fit well with a tiny exception of Asus RT-AC88U which somehow was designed to have switch 5 connected to an extra switch. This case was simply handled with a /delete-property/.

| | | | | | | | | | | | | | | During the removal of the skeleton.dtsi file with commit abe60a3a7afb ("ARM: dts: Kill off skeleton{64}.dtsi") a number of Broadcom SoCs were converted, but a few were left unoticed, now causing boot failures with v5.1 since the kernel cannot find suitable memory. Updating the .dtsi files with the property will be done next, since there are some memory nodes that do not follow the proper naming convention and lack an unit name.

* ARM: dts: BCM5301X: Make USB 3.0 PHY use MDIO PHY driverVivek Unune2018-07-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the USB 3.0 PHY in bcm5301x.dtsi uses platform driver which requires register range "ccb-mii" <0x18003000 0x1000>. This range overlaps with MDIO cmd and param registers (<0x18003000 0x8>). Essentially, the platform driver partly acts like a MDIO bus driver, hence to use of this register range. In some Northstar devices like Linksys EA9500, secondary switch is connected via external MDIO. The only way to access and configure the external switch is via MDIO bus. When we enable the MDIO bus in it's current state, the MDIO bus and any child buses fail to register because of the register range overlap. On Northstar, the USB 3.0 PHY is connected at address 0x10 on the internal MDIO bus. This change moves the usb3_phy node and makes it a child node of internal MDIO bus. Thanks to Rafał Miłecki's commit af850e14a7ae ("phy: bcm-ns-usb3: add MDIO driver using proper bus layer") the same USB 3.0 platform driver can now act as USB 3.0 PHY MDIO driver.

* ARM: dts: BCM5301X: Relicense most DTS files to the GPL 2.0+ / MITRafał Miłecki2018-05-041-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | These files were created and ever touched by a group of three people only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC. Introducing and discussing SPDX-License-Identifier resulted in a conclusion that ISC is a not recommended license (see also a license-rules.rst). Moveover an old e-mail from Alan Cox was pointed which explained that dual licensing is a safer solution than depending on a common compatibility belief. This commit switches most of BCM5301X DTS files to dual licensing using: 1) GPL 2.0+ to make sure they are compatible with Linux kernel 2) MIT to allow sharing with more permissive projects Both licenses belong to the preferred ones (see LICENSES/preferred/). An attempt to relicense remaining files will be made separately and will require approve from more/other developers.

| | | | | | | | | | | | | | Every device tested so far got UART0 (at 0x18000300) working as serial console. It's most likely part of reference design and all vendors use it that way. It seems to be easier to enable it by default and just disable it if we ever see a device with different hardware design.
