MIPS: Ignore relocs against __ex_table for relocatable kernel

2025-02-27T10:07:50+00:00

Since commit 6f2c2f93a190 ("scripts/sorttable: Remove unneeded
Elf_Rel"), sorttable no longer clears relocs against __ex_table,
claiming "it was never used."  But in fact MIPS relocatable kernel had
been implicitly depending on this behavior, so after this commit the
MIPS relocatable kernel has started to spit oops like:

	CPU 1 Unable to handle kernel paging request at virtual address 000000fffbbdbff8, epc == ffffffff818f9a6c, ra == ffffffff813ad7d0
	... ...
	Call Trace:
	[] __raw_copy_from_user+0x48/0x2fc
	[] cp_statx+0x1a0/0x1e0
	[] do_statx_fd+0xa8/0x118
	[] sys_statx+0xd8/0xf8
	[] syscall_common+0x34/0x58

So ignore those relocs on our own to fix the issue.

mips: dts: ralink: mt7628a: update system controller node and its consumers

2025-02-27T09:38:26+00:00

Current MT7628A device tree file system controller node is wrong since it is
not matching bindings. Hence, update it to match current bindings updating
it also to use new introduced clock constants.

mips: dts: realtek: Add restart to Cisco SG220-26P

2025-02-21T14:10:26+00:00

Define a gpio-restart node to the Cisco SG220-26P so the device can be
rebooted using the SoC's hard reset pin. Set the priority to 192 so the
gpio-restart method takes priority over the watchdog restart.

mips: dts: realtek: Add RTL838x SoC peripherals

2025-02-21T14:10:22+00:00

Add some of the SoC's CPU peripherals currently supported:
  - GPIO controller with support for 24 GPIO lines, although not all
    lines are brought out to pads on the SoC package. These lines can
    generate interrupts from external sources.
  - Watchdog which can be used to restart the SoC if no external restart
    logic is present.
  - SPI controller, primarily used to access NOR flash

mips: dts: realtek: Replace uart clock property

2025-02-21T14:10:17+00:00

Add a fixed clock to define the clock frequency of the Lexra bus and use
this for the two uart nodes instead of a separate clock-frequency
property.
