arm64: dts: imx8mn-tqma8mqnl: fix LDO5 power off

2026-04-02T11:09:48+00:00

commit 8adc841d43ebceabec996c9dcff6e82d3e585268 upstream. Fix SD card removal caused by automatic LDO5 power off after boot To prevent this, add vqmmc regulator for USDHC, using a GPIO-controlled regulator that is supplied by LDO5. Since this is implemented on SoM but used on baseboards with SD-card interface, implement the functionality on SoM part and optionally enable it on baseboards if needed.

arm64: dts: renesas: r9a09g057: Remove wdt{0,2,3} nodes

2026-03-25T10:08:51+00:00

[ Upstream commit a3f34651de4287138c0da19ba321ad72622b4af3 ] The HW user manual for the Renesas RZ/V2H(P) SoC (a.k.a r9a09g057) states that only WDT1 is supposed to be accessed by the CA55 cores. WDT0 is supposed to be used by the CM33 core, WDT2 is supposed to be used by the CR8 core 0, and WDT3 is supposed to be used by the CR8 core 1. Remove wdt{0,2,3} from the SoC specific device tree to make it compliant with the specification from the HW manual. This change is harmless as there are currently no users of the wdt{0,2,3} device tree nodes, only the wdt1 node is actually used.

arm64: dts: rockchip: Do not enable hdmi_sound node on Pinebook Pro

2026-03-04T12:21:46+00:00

[ Upstream commit b18247f9dab735c9c2d63823d28edc9011e7a1ad ] Remove the redundant enabling of the hdmi_sound node in the Pinebook Pro board dts file, because the HDMI output is unused on this device. [1][2] This change also eliminates the following kernel log warning, which is caused by the unenabled dependent node of hdmi_sound that ultimately results in the node's probe failure: platform hdmi-sound: deferred probe pending: asoc-simple-card: parse error [1] https://files.pine64.org/doc/PinebookPro/pinebookpro_v2.1_mainboard_schematic.pdf [2] https://files.pine64.org/doc/PinebookPro/pinebookpro_schematic_v21a_20220419.pdf Cc: stable@vger.kernel.org Fixes: 5a65505a69884 ("arm64: dts: rockchip: Add initial support for Pinebook Pro") Signed-off-by: Jun Yan Reviewed-by: Peter Robinson Reviewed-by: Dragan Simic Link: https://patch.msgid.link/20260116151253.9223-1-jerrysteve1101@gmail.com Signed-off-by: Heiko Stuebner Signed-off-by: Sasha Levin

arm64: dts: apple: t8112-j473: Keep the HDMI port powered on

2026-03-04T12:21:39+00:00

[ Upstream commit 3e4e729325131fe6f7473a0673f7d8cdde53f5a0 ] Add the display controller and DPTX phy power-domains to the framebuffer node to keep the framebuffer and display out working after device probing finished. The OS has more control about the display pipeline used for the HDMI output on M2 based devices. The HDMI output is driven by an integrated DisplayPort to HDMI converter (Parade PS190). The DPTX phy is now controlled by the OS and no longer by firmware running on the display co-processor. This allows using the second display controller on the second USB type-c port or tunneling 2 DisplayPort connections over USB4/Thunderbolt. The m1n1 bootloader uses the second display controller to drive the HDMI output. Adjust for this difference compared to the notebooks as well.

arm64: dts: qcom: x1e80100: Add missing TCSR ref clock to the DP PHYs

2026-03-04T12:21:38+00:00

[ Upstream commit 0907cab01ff9746ecf08592edd9bd85d2636be58 ] The DP PHYs on X1E80100 need the ref clock which is provided by the TCSR CC. The current X Elite devices supported upstream work fine without this clock, because the boot firmware leaves this clock enabled. But we should not rely on that. Also, even though this change breaks the ABI, it is needed in order to make the driver disables this clock along with the other ones, for a proper bring-down of the entire PHY. So lets attach it to each of the DP PHYs in order to do that.
