[PATCH v2 0/7] LoongArch: Add built-in dtb support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all:

This patchset introduces LoongArch's built-in dtb support.

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.

-----
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.
