5 daysARM: dts: imx6q-ba16: fix RTC interrupt levelIan Ray1-1/+1
[ Upstream commit e6a4eedd49ce27c16a80506c66a04707e0ee0116 ] RTC interrupt level should be set to "LOW". This was revealed by the introduction of commit: f181987ef477 ("rtc: m41t80: use IRQ flags obtained from fwnode") which changed the way IRQ type is obtained.

5 daysARM: 9461/1: Disable HIGHPTE on PREEMPT_RT kernelsSebastian Andrzej Siewior1-1/+1
[ Upstream commit fedadc4137234c3d00c4785eeed3e747fe9036ae ] gup_pgd_range() is invoked with disabled interrupts and invokes __kmap_local_page_prot() via pte_offset_map(), gup_p4d_range(). With HIGHPTE enabled, __kmap_local_page_prot() invokes kmap_high_get() which uses a spinlock_t via lock_kmap_any(). This leads to an sleeping-while-atomic error on PREEMPT_RT because spinlock_t becomes a sleeping lock and must not be acquired in atomic context. The loop in map_new_virtual() uses wait_queue_head_t for wake up which also is using a spinlock_t. Since HIGHPTE is rarely needed at all, turn it off for PREEMPT_RT to allow the use of get_user_pages_fast().

2025-12-18ARM: 9464/1: fix input-only operand modification in load_unaligned_zeropad()Liyuan Pang1-5/+5
[ 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.

2025-12-18ARM: dts: am33xx: Add missing serial console speedGeert Uytterhoeven12-12/+12
[ Upstream commit 9c95fc710b0d05f797db9e26d56524efa74f8978 ] Without a serial console speed specified in chosen/stdout-path in the DTB, the serial console uses the default speed of the serial driver, unless explicitly overridden in a legacy console= kernel command-line parameter. After dropping "ti,omap3-uart" from the list of compatible values in DT, AM33xx serial ports can no longer be used with the legacy OMAP serial driver, but only with the OMAP-flavored 8250 serial driver (which is mutually-exclusive with the former). However, replacing CONFIG_SERIAL_OMAP=y by CONFIG_SERIAL_8250_OMAP=y (with/without enabling CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP) may not be sufficient to restore serial console functionality: the legacy OMAP serial driver defaults to 115200 bps, while the 8250 serial driver defaults to 9600 bps, causing no visible output on the serial console when no appropriate console= kernel command-line parameter is specified. Fix this for all AM33xx boards by adding ":115200n8" to chosen/stdout-path. This requires replacing the "&uartN" reference by the corresponding "serialN" DT alias.

Rename the 'ssi2' and 'aud3' nodes to 'mux-ssi2' and 'mux-aud3' in the audmux configuration of imx51-zii-rdu1.dts to comply with the naming convention in imx-audmux.yaml.

2025-10-20ARM: dts: imx6ull-engicam-microgea-rmm: fix report-rate-hz valueDario Binacchi1-1/+1
The 'report-rate-hz' property for the edt-ft5x06 driver was added and handled in the Linux kernel by me with patches [1] and [2] for this specific board. The v1 upstream version, which was the one applied to the customer's kernel, used the 'report-rate' property, which was written directly to the controller register. During review, the 'hz' suffix was added, changing its handling so that writing the value directly to the register was no longer possible for the M06 controller. Once the patches were accepted in mainline, I did not reapply them to the customer's kernel, and when upstreaming the DTS for this board, I forgot to correct the 'report-rate-hz' property value. The property must be set to 60 because this board uses the M06 controller, which expects the report rate in units of 10 Hz, meaning the actual value written to the register is 6.

"mac3" controller was removed from the initial version of fuji-data64 dts because the rgmii setting is incorrect, but dropping mac3 leads to regression in the existing fuji platform, because fuji.dts simply includes fuji-data64.dts.

2025-10-15Remove long-stale ext3 defconfig optionLinus Torvalds1-1/+0
Inspired by commit c065b6046b34 ("Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs") I looked around for any other left-over EXT3 config options, and found some old defconfig files still mentioned CONFIG_EXT3_DEFAULTS_TO_ORDERED. That config option was removed a decade ago in commit c290ea01abb7 ("fs: Remove ext3 filesystem driver"). It had a good run, but let's remove it for good.

Unfortunately, there were a number of defconfigs that still used CONFIG_EXT3_FS which the cleanup commit didn't fix up. This led to a large number of defconfig test builds to fail. Oops.

2025-10-13ARM: dts: broadcom: rpi: Switch to V3D firmware clockStefan Wahren2-0/+17
Until commit 919d6924ae9b ("clk: bcm: rpi: Turn firmware clock on/off when preparing/unpreparing") the clk-raspberrypi driver wasn't able to change the state of the V3D clock. Only the clk-bcm2835 was able to do this before. After this commit both drivers were able to work against each other, which could result in a system freeze. One step to avoid this conflict is to switch all V3D consumer to the firmware clock.

A key feature for the new bitmap are that the IO fastpath is lockless. If a user issues lots of write IO to the same bitmap bit in a short time, only the first write has additional overhead to update bitmap bit, no additional overhead for the following writes. By supporting only resync or recover written data, means in the case creating new array or replacing with a new disk, there is no need to do a full disk resync/recovery. - Switch ->getgeo() and ->bios_param() to using struct gendisk rather than struct block_device. - Rust block changes via Andreas. This series adds configuration via configfs and remote completion to the rnull driver. The series also includes a set of changes to the rust block device driver API: a few cleanup patches, and a few features supporting the rnull changes.

Linux has been working on these for a while but stil requires patches. - Axis Artpec8 is an Armv8 chip based on Samsung Exynos design, unlike the earlier Armv7 Artpec6 from the same company that was part of a separate family of chips. - NXP i.MX91 is a cut-down version of i.MX93, using only a single Cortex-A55 core. - Qualcomm Lemans Auto is a variant of the Lemans SoC that was originally merged under the sa8775p name, the differences being mostly the firmware configuration of the platform. - Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44), RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial bedded SoCs based on Cortex-A55 cores In total, there are 65 new machines, including: - Industrial embedded system and single-board computers based on NXP, Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips. - Reference boards for the newly added Renesas, Qualcomm, NXP and Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC - Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1 chips. - Several Samsung phones using Qualcomm Snapdragon chips - Set-top boxes based on Allwinner H313 - Five BMC boards using 32-bit ASpeed SoCs - Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708 (ARMv7) SoCs Two machines get phased out because they were available only in small quantities but never made it into products: one STi407 based reference board, and a Snapdragon 845 based Chromebook. Aside from the newly added machines, a lot of work went into improving hardware support on the existing machines and cleaning up contents for validation" * tag 'soc-dt-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (931 commits) arm64: dts: apm-shadowcat: Drop "apm,xgene2-pcie" compatible arm64: dts: apm-shadowcat: Move slimpro nodes out of "simple-bus" node ARM: dts: microchip: sam9x7: Add qspi controller arm64: dts: qcom: Add MST pixel streams for displayport arm64: dts: qcom: sm6350: correct DP compatibility strings arm64: dts: qcom: monaco-evk: Enable Adreno 623 GPU arm64: dts: qcom: qcs8300-ride: Enable Adreno 623 GPU arm64: dts: qcom: qcs8300: Add gpu and gmu nodes arm64: dts: allwinner: h313: Add Amediatech X96Q dt-bindings: arm: sunxi: Add Amediatech X96Q arm64: dts: apple: t8015: Add SPMI node arm64: dts: apple: t8012: Add SPMI node arm64: dts: apple: Add J180d (Mac Pro, M2 Ultra, 2023) device tree arm64: dts: rockchip: Add devicetree for the ROC-RK3588-RT dt-bindings: arm: rockchip: Add Firefly ROC-RK3588-RT arm64: dts: rockchip: update pinctrl names for Radxa E52C arm64: dts: rockchip: remove vcc_3v3_pmu regulator for Radxa E52C arm64: dts: apple: Add J474s, J475c and J475d device trees arm64: dts: apple: Add J414 and J416 Macbook Pro device trees arm64: dts: apple: Add initial t6020/t6021/t6022 DTs ...
2025-10-02ARM: versatile: clock: convert from round_rate() to determine_rate()Brian Masney1-4/+5
The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch on the cover letter of this series.

2025-10-02ARM: configs: u8500: Set NFC_SHDLC as built-inJihed Chaibi1-1/+1
The CONFIG_NFC_SHDLC=m setting in u8500_defconfig causes a Kconfig warning because the NFC_SHDLC symbol does not support being built as a module.
