* ramips: dts: add the missing interrupt properties for GPIO nodesShiji Yang2024-10-251-3/+20
| | | | | | | | | | | The Ralink GPIO driver supports irqchip function. Hence we need to add "interrupt-parent" and "interrupt-controller" properties to make sure it works properly. It is worth noting that all GPIO devices share the same interrupt line.

* ramips: gpio: always use dynamic GPIO numberspace baseShiji Yang2024-07-041-4/+0
| | | | | | | | | | | The new numberspace base starts from 512 instead of 0. The number base seems come from the kernel symbol CONFIG_GPIOLIB_FASTPATH_LIMIT. Suppress warning: gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation. Signed-off-by: Shiji Yang <yangshiji66@qq.com>

* ramips: remove useless resets properties from SoC dtsiShiji Yang2023-12-251-9/+0
| | | | | | | | | | | | | | | These drivers don't request reset control. And most reset properties even have incorrect reset source definitions. 1. interrupt controller, ref: arch/mips/ralink/irq.c 2. memory controller, ref: arch/mips/ralink/of.c 3. gpio controller, ref: drivers/gpio/gpio-ralink.c (local patch) 4. systic, ref: arch/mips/ralink/cevt-rt3352.c 5. pwm, ref: drivers/pwm/pwm-mediatek-ramips.c (local patch) Tested on MT7620 && MT7628.

* ramips: add proper system clock and reset driver support for legacy SoCsShiji Yang2023-07-301-29/+37
| | | | | | | | | | | | | | | | | | | | This series of upstream patches properly implement a clock and reset driver for old ralink SoCs[1]. And it includes some related fixes[2] and improvements[3][4]. All patches have been merged into linux-next. They will be part of upcoming Linux 6.5. In order to switch to the new system controller driver, all clocks and resets properties in SoC dtsi have been updated, and kernel symbol "CONFIG_CLK_MTMIPS" have been added to the kernel config files.

* ramips: gpio-ralink: use ngpios, not ralink,num-gpiosIlya Lipnitskiy2021-04-151-4/+4
| | | | | | | | | | | | | | | | DTS properties that match *-gpios are treated specially. Use ngpios instead, as most GPIO drivers upstream do. Fixes 5.10 DTS errors such as: OF: /palmbus@300000/gpio@600: could not find phandle Fixes DTC warnings such as: Warning (gpios_property): /palmbus@300000/gpio@600:ralink,num-gpios: Could not get phandle node for (cell 0) Signed-off-by: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com> Cc: Daniel Golle <daniel@makrotopia.org>
* ramips: move aliases to the top in SoC DTSI filesAdrian Schmutzler2021-02-221-6/+6
| | | | | | | The aliases node is expected as one of the first entries, and having it there matches alphabetic sorting as well. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: move dts-v1 statement to top-level DTSI filesAdrian Schmutzler2020-09-251-0/+2
| | | | | | | | | | | | | | | | | The "/dts-v1/;" identifier is supposed to be present once at the top of a device tree file after the includes have been processed. In ramips, we therefore requested to have in the DTS files so far, and omit it in the DTSI files. However, essentially the syntax of the parent mtxxxx/rtxxxx DTSI files already determines the DTS version, so putting it into the DTS files is just a useless repetition. Consequently, this patch puts the dts-v1 statement into the top-level SoC-based DTSI files, and removes all other occurences. Since the dts-v1 statement needs to be before any other definitions, this also moves the includes accordingly where necessary. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: replace pinctrl property namesChuanhong Guo2020-04-121-14/+14
| | | | | | | | | | | | | | Upstream pinctrl driver in drivers/staging uses groups/function/ralink,num-gpios instead of ralink,group/ralink,function/ralink,nr-gpio Replace these properties in dts as well as the pinctrl driver in patches-4.14.

* ramips: set usb led trigger via devicetreeMathias Kresin2018-10-071-0/+14
| | | | | | | | | | Assign the usbdev trigger via devicetree for all subtargets and drop the userspace handling of the usb leds. With the change all usb ports are triggering the usb led instead of only usb 1.1 XOR usb 2.0 XOR usb 3.0 as it was before. Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: fix rt3883 pinmux for second SPIMathias Kresin2018-08-291-2/+2
| | | | | | | The rt3883 doesn't have a pinmux group named spi_cs1. The cs1 is part of the pci group. The function pci-func enables the second chip select. Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: fix rt3883 pci pinmuxMathias Kresin2018-08-291-1/+1
| | | | | | | | | | The PCI pins need to be set to "PCI Host support one device" to allow the use of one PCI device and flash memory. The pci-fnc function is intended to be used if no PCI is used but flash, nand or the codec functionality is. Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: fix pci/pcie related dtc warningsMathias Kresin2018-08-041-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ranges property to the PCI bridges where missing. Add the unit address to PCI bridge where missing. Rework the complete rt3883 pci node. Drop the PCI unit nodes from the dtsi. They are not used by any dts file and should be rather in the dts than in the SoC dtsi. Express the PCI-PCI bridge in a clean devicetree syntax. The ralink,pci-slot isn't used by any driver, drop it. Move the pci interrupt controller out of the pci node. It doesn't share the same reg and therefore should be an independent/SoC child node. Move the pci related rt3883 pinctrl setting to the dtsi instead of defining the very same for each rt3883 board. If the device_type property is used for PCI units, the unit is treated as pci bridge which it isn't. Drop it for PCI units. Reference pci-bridges or the pci node defined in the dtsi instead of recreating the whole node hierarchy. It allows to change the referenced node in the dtsi without the need to touch all dts. Fix the PCI(e) wireless unit addresses. All our PCI(e) wireless chips are the first device on the bus. The unit address has to be the bus address instead of the PCI vendor/device id.

* ramips: use ralink,nr-gpio instead of ralink,num-gpiosMathias Kresin2018-08-041-4/+4
| | | | | | | | | | | Since commit c1e7738988f5 ("checks: add gpio binding properties check") dtc treats any *-gpios and *-gpio property as phandle at least during checks. The only whitelisted property is nr-gpio. Use ralink,nr-gpio in favour of ralink,num-gpios to get rid of false positive warnings. Signed-off-by: Mathias Kresin <dev@kresin.me>
* ramips: fix cpu interrupt controller dtc warningsMathias Kresin2018-08-041-1/+1
| | | | | | | The cpu interrupt controller doesn't have a reg property, hence we can't use a unit address in the node name. Signed-off-by: Mathias Kresin <dev@kresin.me>

* ramips: fix usbphy DT nodes on linux 4.14Vianney le Clément de Saint-Marcq2018-04-071-4/+5
| | | | | | | | | | | | | | The Ralink USB PHY driver merged into mainline has a slightly different device tree binding than the patch that was used with linux 4.9. The new driver requires a `ralink,sysctl` node pointing to the `syscon` node. This patch also sets `#phy-cells` to 0, as recommended by the mainline documentation [1].

* ramips: DTS modificationsStanislav Galabov2016-05-121-0/+7
| | | | | | | | | | | | | | This commit makes the following modifications to ramips dts files: 1. Add clkctrl node to all dtsi files (although not used for now) 2. Add clocks and clock-names properties to some nodes (usbphy, pci) 3. Add usbphy node for rt3050 (although not used for now) 4. Add clock-frequency to uart nodes in mt7621.dtsi and mt7628an.dtsi These modifications, although not fully used at the moment, will make it easier for FreeBSD to adopt and use LEDE ramips dts files with minimal changes for easier maintenance.
