ARM: 9464/1: fix input-only operand modification in load_unaligned_zeropad()

2025-12-18T13:00:13+00:00

[ Upstream commit edb924a7211c9aa7a4a415e03caee4d875e46b8e ]

In the inline assembly inside load_unaligned_zeropad(), the "addr" is
constrained as input-only operand. The compiler assumes that on exit
from the asm statement these operands contain the same values as they
had before executing the statement, but when kernel page fault happened, the assembly fixup code "bic %2 %2, #0x3" modify the value of "addr", which may lead to an unexpected behavior.

Use a temporary variable "tmp" to handle it, instead of modifying the
input-only operand, just like what arm64's load_unaligned_zeropad()
does.

ARM: dts: samsung: exynos4412-midas: turn off SDIO WLAN chip during system suspend

2025-12-18T13:00:01+00:00

[ Upstream commit 2ff147fdfa99b8cbb8c2833e685fde7c42580ae6 ]

Commit 8c3170628a9c ("wifi: brcmfmac: keep power during suspend if board
requires it") changed default behavior of the BRCMFMAC driver, which now
keeps SDIO card powered during system suspend to enable optional support
for WOWL. This feature is not supported by the legacy Exynos4 based
boards and leads to WLAN disfunction after system suspend/resume cycle.
Fix this by annotating SDIO host used by WLAN chip with
'cap-power-off-card' property, which should have been there from the
beginning.

Move st,adc-freq, st,mod-12b, st,ref-sel, and st,sample-time properties
from the touchscreen subnode to the parent touch@44 node. These properties
are defined in the st,stmpe.yaml schema for the parent node, not the
touchscreen subnode, resolving the validation error about unevaluated
properties.

ARM: dts: omap3: n900: Correct obsolete TWL4030 power compatible

2025-12-18T12:59:34+00:00

[ Upstream commit 3862123e9b56663c7a3e4a308e6e65bffe44f646 ]

The "ti,twl4030-power-n900" compatible string is obsolete and is not
supported by any in-kernel driver. Currently, the kernel falls back to
the second entry, "ti,twl4030-power-idle-osc-off", to bind a driver to
this node.

Make this fallback explicit by removing the obsolete board-specific
compatible. This preserves the existing functionality while making the
DTS compliant with the new, stricter 'ti,twl.yaml' binding.
