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

2026-07-24T14:11:26+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

2026-07-24T14:11:26+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

2026-07-24T14:11:26+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.

ARM: dts: stm32: stm32mp15x-mecio1-io: Fix GPIO names typo

commit b04ccecb714de913e360f0866c66f38e1606e89b upstream. The reset pins for the LPOUT lines were incorrectly prefixed with "GPOUT" instead of "LPOUT" in the gpio-line-names array. Fix these typos so the pin names consistently match the LPOUT0-4 signals they belong to.

ARM: dts: stm32: stm32mp15x-mecio1-io: Enable internal ADC reference

2026-07-24T14:11:26+00:00

commit c84f22405085d91cd5f0c5b967318371c07904ba upstream. Switch the ADC reference supply from the general 3.3V rail to the internal 2.5V VREFBUF regulator. The ADC circuits on this board are designed for the internal 2.5V reference. Without this change, all ADC measurement values are incorrect.

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

2026-07-24T14:11:26+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

2026-07-24T14:11:26+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.

ARM: dts: am335x-sl50: Fix audio bitclock and frame master endpoint

2026-07-24T14:10:44+00:00

[ Upstream commit 2bc564f46b00dc4f4331fc337277ff3f5fac8a4e ] The cpu_endpoint in mcasp0 specifies the TLV320AIC3106 codec as the bitclock and frame master, but the phandles point to the codec's port node (codec_port) rather than its endpoint node (codec_endpoint). audio-graph-card calls simple_util_parse_daifmt() with ep_codec set to the endpoint node (codec_endpoint). The function resolves the bitclock-master phandle and checks whether it equals ep_codec. Since codec_port is the parent of codec_endpoint, not the endpoint itself, the comparison always evaluates to false. This causes the mcasp0 CPU side to be silently configured as bitclock and frame master instead of the codec, which is the opposite of the intended configuration. Fix by pointing bitclock-master and frame-master to codec_endpoint.
