This reverts commit d5e2d038dbece821f1af57acbeded3aa9a1832c1.

We have a report of this chip being used on a

  SURECOM EP-320X-S 100/10M Ethernet PCI Adapter

which could still have been purchased in some parts
of the world 3 years ago.

MIPS: Workaround clang inline compat branch issue

2023-02-28T22:09:49+00:00

Clang is unable to handle the situation that a chunk of inline
assembly ends with a compat branch instruction and then compiler
generates another control transfer instruction immediately after
this compat branch. The later instruction will end up in forbidden
slot and cause exception.

Workaround by add a option to control the use of compact branch.
Currently it's selected by CC_IS_CLANG and hopefully we can change
it to a version check in future if clang manages to fix it.

Fix boot on boston board.

mips: dts: ralink: mt7621: add phandle to system controller node for watchdog

2023-02-28T22:09:32+00:00

To allow to access system controller registers from watchdog driver code
add a phandle in the watchdog 'wdt' node. This avoid using arch dependent
operations in driver code.

mips: dts: ralink: mt7621: rename watchdog node from 'wdt' into 'watchdog'

2023-02-28T22:09:15+00:00

Watchdog nodes must use 'watchdog' for node name. When a 'make dtbs_check'
is performed the following warning appears:

wdt@100: $nodename:0: 'wdt@100' does not match '^watchdog(@.*|-[0-9a-f])?$'

Fix this warning up properly renaming the node into 'watchdog'.

mips: ralink: make SOC_MT7621 select PINCTRL

2023-02-27T22:47:29+00:00

Currently, out of every Ralink SoC, only the dt-binding of the MT7621 SoC
uses pinctrl. Because of this, PINCTRL is not selected at all. Make
SOC_MT7621 select PINCTRL.

Remove PINCTRL_MT7621, enabling it for the MT7621 SoC will be handled under
the PINCTRL_MT7621 option.

MIPS: cevt-r4k: Offset the value used to clear compare interrupt

2023-02-27T22:45:17+00:00

In c0_compare_int_usable we clear compare interrupt by write value
just read out from counter to compare register.

However sometimes if those all instructions are graduated together
then it's possible that at the time compare register is written, the
counter haven't progressed, thus the interrupt is triggered again.

It also applies to QEMU that instructions is executed significantly
faster then counter.

Offset the value used to clear interrupt by one to prevent that happen.

MIPS: smp-cps: Don't rely on CP0_CMGCRBASE

2023-02-27T22:44:57+00:00

CP0_CMGCRBASE is not always available on CPS enabled system
such as early proAptiv.

For early SMP bring up where we can't safely access memeory,
we patch the entry of CPS NMI vector to inject CMGCR address
directly into register during early core bringup.

For VPE bringup as the core is already coherenct at that point
we just read the variable to obtain the address.
