As we know, the Loongson-2K family supports DT. Inevitably, some systems do not provide a useful device tree to the kernel at boot time. Chasing around bootloaders for these systems is a headache, so we just keep a device tree table in the kernel, keyed by the dts filename, that contains the relevant DTBs. Thanks. ----- V4: patch(1/7): - Drop device_type property. patch(2/7): - Rename board.yaml to loongson.yaml. patch(4/7): - Keep the ranges attribute after compatible; - Add bootargs = "ttyS0,115200", which is needed for reference board; patch(5/7): - Keep the ranges attribute after compatible; - Add bootargs = "ttyS0,115200", which is needed for reference board; - Change node name global-utilities to chipid. patch(6/7): - Keep the ranges attribute after compatible; - Add bootargs = "ttyS0,115200", which is needed for reference board. Link to V3: https://lore.kernel.org/all/cover.1692618548.git.zhoubinbin@loongson.cn/ V3: patch(1/7): - Add reference to the common cpu schema. patch(2/7): - Add reviewed-by tag. patch(4/7): - Drop bootargs; - Move the cpus node to dtsi, which is part of the SoC. patch(5/7): - Drop bootargs; - Move the cpus node to dtsi, which is part of the SoC; - Fix gmac0/1-mdio node: compatible is always the first property; - Drop i2c-gpio node. patch(6/7): - Drop bootargs; - Move the cpus node to dtsi, which is part of the SoC. - Changes liointc to liointc-1.0, for Loongson-2K2000 has 32 interrupt sources. Link to V2: https://lore.kernel.org/all/cover.1692088166.git.zhoubinbin@loongson.cn/ V2: patch(1/7): - Drop model and clock-frequency properties; - Add clocks property; - Rewrite the description. patch(2/7): - Add the proper compatibles for boards. patch(4/7)(5/7)(6/7): - Format commit message head; - Drop undocumented compatible, such as pci_bridge compatible; - Distinguish the attributes, put SoC-related into DTSI and board-related into DTS; - Check DTS with 'make dtbs_check W=1'. patch(7/7) - New patch; - Parses Molde name and CPU MHz from the DTS attribute.
