ARM: dts: BCM5301X: fix PCIe controller 2 second interrupt

2026-08-19T16:17:16+00:00

[ Upstream commit bab4d538f8485e0d48538fcb82b285df3779278e ] PCIe controller 2 has interrupts 0-4 mapping to GIC SPI 138-142. The mapping for interrupt 1 was incorrectly set to 138 due to a copy-paste error. Fix it to 139.

ARM: npcm: Fix OF node refcount leaks in SMP setup

2026-08-19T16:17:15+00:00

[ Upstream commit 8eb052f48331474c2789d07b7f11165c323bd2f9 ] npcm7xx_smp_boot_secondary() and npcm7xx_smp_prepare_cpus() look up the GCR and SCU nodes with of_find_compatible_node(). The returned nodes are used for of_iomap(), but the node references are never released. of_iomap() does not consume the device node reference, and iounmap() only releases the MMIO mapping. Drop each node reference after the corresponding mapping attempt.

ARM: dts: stm32: stm32mp15x-mecio1-io: Move expander gpio-line-names to board files

2026-07-24T14:16:52+00:00

commit a0d6c2a06fffff47bcca4d5bfdab4cc428a315fc upstream. Move the gpio-line-names properties for the I2C GPIO expanders (gpio0 and gpio1) out of the common mecio1-io.dtsi file and into the specific board dts files. The layout originally defined in the common include file belonged to the mecio1r1 (Revision 1) hardware. This layout is moved 1:1 into the stm32mp153c-mecio1r1.dts file. The mecio1r0 (Revision 0) hardware utilizes a completely different pinout for these expanders. A new, accurate mapping reflecting the Revision 0 schematics is added to stm32mp151c-mecio1r0.dts.

ARM: dts: stm32: stm32mp15x-mecio1-io: Fix expander gpio line typo

2026-07-24T14:16:52+00:00

commit dfb93c4acce8ad9c4f573128b2cf7ddb936e0de7 upstream. Fix a copy-paste error in the GPIO line names for the TCA6416 expander (gpio@20). The common mecio1-io include file was originally defined using the mecio1r1 (Revision 1) hardware layout, but incorrectly labeled pin 13 as "HSIN9_BIAS" instead of the actual "HSIN7_BIAS" present in the schematics.

ARM: dts: stm32: stm32mp15x-mecio1-io: Move gpio-line-names to board files

2026-07-24T14:16:52+00:00

commit 4f5069609ac99894c0632d8b8c4c016f85199de9 upstream. Move the gpio-line-names properties out of the common mecio1-io.dtsi file and into the specific board dts files. The pinout originally defined in the common include file belonged to the mecio1r0 (Revision 0) hardware. This is moved 1:1 into the stm32mp151c-mecio1r0.dts file without any modifications. A large number of GPIO pins are swapped on the mecio1r1 (Revision 1) hardware, so a new, board-specific gpio-line-names mapping is added to stm32mp153c-mecio1r1.dts to reflect those hardware changes.

commit b04ccecb714de913e360f0866c66f38e1606e89b upstream. The reset pins for the LPOUT lines were incorrectly prefixed with "GPOUT" instead of "LPOUT" in the gpio-line-names array.

commit c84f22405085d91cd5f0c5b967318371c07904ba upstream. Switch the ADC reference supply from the general 3.3V rail to the internal 2.5V VREFBUF regulator.

ARM: dts: stm32: stm32mp15x-mecio1-io: Move divergent mecio1 ADC channels to board files

2026-07-24T14:16:52+00:00

commit 70f1d8fcbd121a40f51b6c846d41e8cbb38ba210 upstream. Move the divergent adc1 channel definitions out of the common mecio1-io.dtsi file and into the specific Revision 0 and Revision 1 board files. The original common file contained incorrect schematic labels for the Revision 0 hardware (e.g., labeling ana0 as p24v_hpdcm instead of ain_aux0) and failed to account for physical signal routing changes between the board revisions. Retain only the strictly shared channels in the common include file. Map the correct channels and schematic labels directly within stm32mp151c-mecio1r0.dts and stm32mp153c-mecio1r1.dts. Crucially, ensure that the required 200us sample time follows the phint1_ain signal to its new physical location on channel 3 for the Revision 1 hardware.

ARM: dts: stm32: stm32mp15x-mecio1-io: Fix ADC sampling times

2026-07-24T14:16:52+00:00

commit 8407e611faf80ce790a393addf7b44cc595742af upstream. Increase the minimum ADC sample times for all configured channels on ADC1 and ADC2 to ensure measurement accuracy meets specifications. The default 5us sample time is insufficient for the internal sampling capacitor to fully charge. Increase the default time to 20us to relax the input impedance requirements. Additionally, the phint0_ain and phint1_ain channels require a much longer sampling period due to their specific circuit design. Increase their sample times to 200us. Remove stale comments regarding clock cycles that no longer match the updated timings.
