from Loongson-2K1000 user manual know that under pci bus the device num is 4, function number is 2 and register is 0x2200 is ohci. the ohci interrupt number is 51. because Loongson-2K1000 has 64 interrupt sources, 0-31 correspond to the device tree liointc0 device node, and the other correspond to liointc1 node. so it should be number 19 correspon to liointc1.

2021-03-12MIPS: ingenic: gcw0: SPI panel does not require active-high CSPaul Cercueil1-1/+0
The NT39016 panel is a fun beast, even though the documentation states that the CS line is active-low, it will work just fine if the CS line is configured as active-high, but it won't work if the CS line is forced low or forced high. Since it did actually work with the spi-cs-high property, this is not a bugfix, but we should nonetheless remove that property to match the documentation.

2021-02-04Add support for Realtek RTL838x/RTL839x switch SoCsBert Vermeulen3-0/+81
The RTL838x/839x family of SoCs are Realtek switches with an embedded MIPS core. * RTL838x - 500MHz 4kce single core - 1Gbit ports and L2 features * RTL839x - 700MHz 34Kc single core - 1Gbit ports and L2 features These switches, depending on the exact part number, will have anywhere between 8 and 52 ports. The MIPS core is wired to a switch cpu port which has a tagging feature allowing us to make use of the DSA subsystem. The SoCs are somewhat basic in certain areas, getting better with more advanced features on newer series. The switch functionality is MMIO-mapped via a large MFD region. The SoCs have the following peripherals * ethernet * switch * uart - ns16550a * spi-flash interface * gpio * wdt * led The code was derived from various vendor SDKs based on Linux v2.6 kernels. This patchset allows us to boot RTL838x/RTL839x units with basic support. Most of the other drivers are already written and functional, and work to get them upstream is already in progress.

The compressed payload is not necesarily 4-byte aligned, at least when compiling with Clang. In that case, the 4-byte value appended to the compressed payload that corresponds to the uncompressed kernel image size must be read using get_unaligned_le32().

Commit c3e2ee657418 ("MIPS: generic: Add support for zboot") added support for self-extracting images to Generic MIPS. However, the intended way to boot Generic MIPS kernels is using FIT Images and UHI boot protocol, but currently there's no way to make self-extracting FIT Image (only legacy uzImages). Add a target for this named "vmlinuz.itb", which will consist of vmlinuz.bin and selected DT blobs. It will allow to have the advantages of both UHI and self-extracting images.

When I update the latest kernel on the Loongson platform used with LS7A bridge chip, the serial console has no output, this is because the machine uses LS7A UART0 instead of CPU UART0, add UART node for LS7A PCH to enhance the compatibility.
