MIPS: Fix a compilation issue

2023-03-17T07:58:01+00:00

[ Upstream commit 109d587a4b4d7ccca2200ab1f808f43ae23e2585 ]

arch/mips/include/asm/mach-rc32434/pci.h:377:
cc1: error: result of ‘-117440512 << 16’ requires 44 bits to represent, but ‘int’ only has 32 bits [-Werror=shift-overflow=]

All bits in KORINA_STAT are already at the correct position, so there is
no addtional shift needed.

eth: fealnx: bring back this old driver

2023-03-11T12:50:46+00:00

commit 8f14820801042c221bb9fe51643a2585cac5dec2 upstream.

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: DTS: CI20: fix otg power gpio

2023-03-10T08:29:53+00:00

commit 0cb4228f6cc9ed0ca2be0d9ddf29168a8e3a3905 upstream.

According to schematics it is PF15 and not PF14 (MIC_SW_EN).
Seems as if it was hidden and not noticed during testing since
there is no sound DT node.

mips: fix syscall_get_nr

2023-03-10T08:29:48+00:00

commit 85cc91e2ba4262a602ec65e2b76c4391a9e60d3d upstream.

The implementation of syscall_get_nr on mips used to ignore the task
argument and return the syscall number of the calling thread instead of
the target thread.

The bug was exposed to user space by commit 201766a20e30f ("ptrace: add
PTRACE_GET_SYSCALL_INFO request") and detected by strace test suite.

of/fdt: run soc memory setup when early_init_dt_scan_memory fails

2023-01-04T00:41:01+00:00

If memory has been found early_init_dt_scan_memory now returns 1. If
it hasn't found any memory it will return 0, allowing other memory
setup mechanisms to carry on.

Previously early_init_dt_scan_memory always returned 0 without
distinguishing between any kind of memory setup being done or not. Any
code path after the early_init_dt_scan memory call in the ramips
plat_mem_setup code wouldn't be executed anymore. Making
early_init_dt_scan_memory the only way to initialize the memory.

Some boards, including my mt7621 based Cudy X6 board, depend on memory
initialization being done via the soc_info.mem_detect function
pointer. Those wouldn't be able to obtain memory and panic the kernel
during early bootup with the message "early_init_dt_alloc_memory_arch:
Failed to allocate 12416 bytes align=0x40".

MIPS: ralink: mt7621: avoid to init common ralink reset controller

2022-12-21T09:45:56+00:00

Commit 38a8553b0a22 ("clk: ralink: make system controller node a reset provider")
make system controller a reset provider for mt7621 ralink SoCs. Ralink init code
also tries to start previous common reset controller which at the end tries to
find device tree node 'ralink,rt2880-reset'. mt7621 device tree file is not
using at all this node anymore. Hence avoid to init this common reset controller
for mt7621 ralink SoCs to avoid 'Failed to find reset controller node' boot
error trace error.
