2024-07-12mips: dts: realtek: Add RTL9302C boardChris Packham3-0/+153
Add support for the RTL9302 SoC and the RTL9302C_2xRTL8224_2XGE reference board. The RTL930x family of SoCs are Realtek switches with an embedded MIPS core (800MHz 34Kc). Most of the peripherals are similar to the RTL838x SoC and can make use of many existing drivers. Add in full DSA switch support is still a work in progress.

2024-07-12mips: dts: realtek: add device_type property to cpu nodeChris Packham1-0/+1
Add device_type = "cpu" to the cpu node for the rtl838x SoC.

2024-07-03MIPS: mobileye: eyeq5: add OLB system-controller nodeThéo Lebrun3-39/+162
The OLB ("Other Logic Block") is a system-controller region hosting clock, reset and pin controllers. It contains registers such as I2C speed mode that need to be accessible by other nodes. Remove fixed-clocks previously used; replace references. Add parent crystal clock, fixed at 30MHz. Add pin nodes for all functions. Add mobileye,eyeq5-olb compatible node, hosting clk, reset and pinctrl. Add reset and pinctrl references to UART nodes.

EyeQ6H (or “High”) is an other SoC from Mobileye still based on the MIPS I6500 architecture as the EyeQ5. The 2 clusters of this SoC contains 4 cores which are capable of running 4 threads. Besides this, it features multiple controllers such as the classic UART, high speed I2C, SPI, as well as CAN-FD, PCIe Gen4, Octal/Quad SPI Flash interface, Gigabit Ethernet, MIPI CSI-2, MIPI DSI, and eMMC 5.1. It also includes a Hardware Security Module, Functional Safety Hardware, and video encoders and more. This commit provides the infrastructure to build a kernel running on EyeQ6H SoC. For now the support is limited and only one CPU core is running.

2023-12-21MIPS: compressed: Use correct instruction for 64 bit codeGregory CLEMENT1-2/+2
The code clearing BSS already use macro or use correct instruction depending if the CPU is 32 bits or 64 bits. However, a few instructions remained 32 bits only. By using the accurate MACRO, it is now possible to deal with memory address beyond 32 bits. As a side effect, when using 64bits processor, it also divides the loop number needed to clear the BSS by 2.

Device binds to proper PCI ID (LOONGSON, 0x7a03), already listed in DTS, so checking for some other compatible does not make sense. It cannot be bound to unsupported platform. Drop useless, incorrect (space in between) and undocumented compatible.

2023-12-11mips: decompress: fix add missing prototypesArnd Bergmann4-14/+29
Patch series "mips: address -Wmissing-prototypes warnings". Address the -Wmissing-prototypes warnings that showed up in mips as the last major architecture after my patch to enable the option everywhere. This patch (of 20): The mips decompressor has some string functions defined locally that are not declared in the right place: arch/mips/boot/compressed/dbg.c:12:13: error: no previous prototype for 'putc' [-Werror=missing-prototypes] arch/mips/boot/compressed/dbg.c:16:6: error: no previous prototype for 'puts' [-Werror=missing-prototypes] arch/mips/boot/compressed/dbg.c:26:6: error: no previous prototype for 'puthex' [-Werror=missing-prototypes] arch/mips/boot/compressed/string.c:11:7: error: no previous prototype for 'memcpy' [-Werror=missing-prototypes] arch/mips/boot/compressed/string.c:22:7: error: no previous prototype for 'memset' [-Werror=missing-prototypes] arch/mips/boot/compressed/string.c:32:15: error: no previous prototype for 'memmove' [-Werror=missing-prototypes] arch/mips/boot/compressed/decompress.c:43:6: error: no previous prototype for 'error' [-Werror=missing-prototypes] arch/mips/boot/compressed/decompress.c:91:6: error: no previous prototype for 'decompress_kernel' [-Werror=missing-prototypes] Include the string.h header where needed and add a decompress.h header to have shared prototypes for the rest.

2023-10-19MIPS: AR7: remove platformWolfram Sang1-5/+0
After a discussion about removing VLYNQ support from the Kernel, it was concluded that its only user, the AR7 platform can go [1]. Even OpenWRT has removed support because these devices are "stuck with 3.18" [2].

2023-06-23MIPS: DTS: CI20: Raise VDDCORE voltage to 1.125 voltsPaul Cercueil1-2/+2
Commit 08384e80a70f ("MIPS: DTS: CI20: Fix ACT8600 regulator node names") caused the VDDCORE power supply (regulated by the ACT8600's DCDC1 output) to drop from a voltage of 1.2V configured by the bootloader, to the 1.1V set in the Device Tree. According to the documentation, the VDDCORE supply should be between 0.99V and 1.21V; both values are therefore within the supported range. However, VDDCORE being 1.1V results in the CI20 being very unstable, with corrupted memory, failures to boot, or reboots at random. The reason might be succint drops of the voltage below the minimum required. Raising the minimum voltage to 1.125 volts seems to be enough to address this issue, while still keeping a relatively low core voltage which helps for power consumption and thermals.
