* realtek: move RTL8231 definitions to board filesSander Vanheule2022-02-201-9/+0
| | | | | | | | | | | | | | The RTL8231 is an external chip, and not part of the SoC. That means it is more appropriate to define it in the board specific (base) files, instead of the DT include for the SoC itself. Moving the RTL8231 definition also ensures that boards with no GPIO expander, or an alternative one, don't have a useless gpio1 node label defined. Tested on a Netgear GS110TPPv1.

* realtek: Update RTL838X DTS to new Realtek IRQ controller notationBirger Koblitz2022-02-171-26/+13
| | | | | | | | Replace the interrupt controller node with the new realtek,rtl-intc node and change all device interrupts to use the 2 field notation: interrupts = <[SoC IRQ] [Index to MIPS IRQ]> Signed-off-by: Birger Koblitz <git@birger-koblitz.de>
* realtek: add missing GPIO irq propertiesSander Vanheule2021-11-281-0/+4
| | | | | | | | | The internal GPIO controller on RTL838x is also an IRQ controller, which requires the 'interrupt-controller' and '#interrupts-cells' properties to be present in the device tree.

* realtek: Add and enable watchdog nodeSander Vanheule2021-11-241-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add and enable the Realtek Otto WDT peripheral found on these SoCs. Default all devices to use standard (cold) reboot and "soc" resets. Devices that require the PLL value fixup before restarting, should pick the "cpu" or "software" reset mode. These devices also need to provide a custom reboot mode, by adding the reboot argument to the kernel command line: WDT reset mode | kernel reboot mode ----------------+--------------------------------------- soc | reboot=cold (default if not specified) cpu | reboot=warm software | reboot=software Preferrably, these devices should use an alternative restart method like gpio-restart to provide reliable restarts. Note that watchdog restarts are not yet exposed, since the _machine_restart override is still present.

* realtek: Add Lexra bus clockSander Vanheule2021-11-241-2/+8
| | | | | | | | | | | | | | | | | The CPU peripherals on RTL83xx/RTL930x are connected to the CPU via the Lexra bus. This bus can provide a clock signal to these peripherals, but no clock driver is currently available. Instead, use a fixed-clock to provide the clock frequency, and update the dependent peripherals. Lexra bus clock frequencies: - RTL838x: 200MHz - RTL839x: 200MHz - RTL930x: 175MHz Signed-off-by: Sander Vanheule <sander@svanheule.net> Tested-by: Stijn Segers <foss@volatilesystems.org> Tested-by: Paul Fertser <fercerpav@gmail.com> Tested-by: Stijn Tintel <stijn@linux-ipv6.be>
* realtek: Consolidate bootargsSander Vanheule2021-11-241-1/+1
| | | | | | | | | | All current devices use identical bootargs, so let's move that to the common devicetree includes.

* realtek: use physical addresses in soc dtsi in 5.10INAGAKI Hiroshi2021-09-261-8/+8
| | | | | | Use physical addresses instead of virtual address in dts files. Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com>
* realtek: add pinmux node of LED_GLB_CTRL to rtl838x.dtsi in dts-5.10INAGAKI Hiroshi2021-09-261-0/+16
| | | | | | | This patch adds a pinctrl-single pinmux node to allow disabling system LED and enabling GPIO 0 (old driver: GPIO 24). Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com>
* realtek: add "soc" node to soc dtsi in dts-5.10INAGAKI Hiroshi2021-09-261-60/+69
| | | | | | Add a "soc" node as a simple-bus to rtl838x.dtsi and rtl930x.dtsi. Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com>
* realtek: update soc dtsi in 5.10 for backported driversINAGAKI Hiroshi2021-09-261-3/+19
| | | | | | | | | | | | | | | this patch updates SoC dtsi (rtl838x.dtsi, rtl930x.dtsi) for the following backported drivers: - gpio-realtek-otto (5.13) - spi-realtek-rtl (5.12) - irq-realtek-rtl (5.12) And, disable SoC GPIO node (gpio0) in rtl930x.dtsi in dts-5.10. Currently, the upstreamed driver doesn't support the GPIO controller on RTL930x SoC. Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com>
* realtek: cleanup and update soc dtsi in 5.10INAGAKI Hiroshi2021-09-261-15/+6
| | | | | | | | | | the following changes are included in this patch: - node is enabled by default, drop 'status = "okay"' - adjust order of "compatible" lines and "reg" lines - add a new blank line before fixed-link node in rtl830x.dtsi Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com>
* realtek: copy dts directory for Kernel 5.10INAGAKI Hiroshi2021-09-261-0/+188
This patch adds "dts-5.10" directory to use backported drivers. There are several specification changes in the new drivers, so there are some compatibility issues in using dts/dtsi files for 5.4. The old DTS files are moved to "dts-5.4", so their corresponding kernel version is obvious as well.
