arm: dts: lpc32xx: add clocks property to Motor Control PWM device tree node

2026-03-04T12:19:37+00:00

[ Upstream commit 71630e581a0e34c03757f5c1706f57c853b92555 ] Motor Control PWM depends on its own supply clock, the clock gate control is present in TIMCLK_CTRL1 register.

ARM: dts: lpc32xx: Set motor PWM #pwm-cells property value to 3 cells

2026-03-04T12:19:37+00:00

[ Upstream commit 65ae9ea77e1f2a20ad2866f99596df7ccdbd3b95 ] Since commit 4cd2f417a0ac ("dt-bindings: pwm: Convert lpc32xx-pwm.txt to yaml format") both types of PWM controlles on NXP LPC32xx SoC fairly gained 3 cells, reflect it in the platform dtsi file.

ARM: dts: allwinner: sun5i-a13-utoo-p66: delete "power-gpios" property

2026-03-04T12:19:36+00:00

[ Upstream commit 0b2761eb1287bd9f62367cccf6626eb3107cef6f ] The P66's device tree includes the reference design dtsi files, which defines a node and properties for the touchpanel in the common design. The P66 dts file then overrides all the properties to match its own design, but as the touchpanel model is different, a different schema is matched. This other schema uses a different name for the GPIO. The original submission added the correct GPIO property, but did not delete the one inherited from the reference design, causing validation errors. Explicitly delete the incorrect GPIO property.

ARM: dts: imx6q-ba16: fix RTC interrupt level

[ 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.

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

2026-01-11T14:21:33+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.
