clk: imx8mq: Correct the CSI PHY sels

2026-05-23T11:06:56+00:00

[ Upstream commit d16f57caa78776e6e8a88b96cb2597797b376138 ] According to i.MX 8M Quad Reference Manual (Section 5.1.2 Table 5-1) MIPI_CSI1_PHY_REF_CLK_ROOT and MIPI_CSI2_PHY_REF_CLK_ROOT have SYSTEM_PLL2_DIV3 available as their second source, which corresponds to sys2_pll_333m rather than sys2_pll_125m.

clk: imx: imx6q: Fix device node reference leak in of_assigned_ldb_sels()

[ Upstream commit 9faf207208951460f3f7eefbc112246c8d28ff1b ] The function of_assigned_ldb_sels() calls of_parse_phandle_with_args() but never calls of_node_put() to release the reference, causing a memory leak. Fix this by adding proper cleanup calls on all exit paths.

clk: imx: imx8-acm: fix flags for acm clocks

2026-05-14T13:30:18+00:00

commit f2c2fc93b4a3efdfcf3805ab74741826d343ff2c upstream. Currently, the flags for the ACM clocks are set to 0. This configuration causes the fsl-sai audio driver to fail when attempting to set the sysclk, returning an EINVAL error. The following error messages highlight the issue: fsl-sai 59090000.sai: ASoC: error at snd_soc_dai_set_sysclk on 59090000.sai: -22 imx-hdmi sound-hdmi: failed to set cpu sysclk: -22 By setting the flag CLK_SET_RATE_NO_REPARENT, we signal that the ACM driver does not support reparenting and instead relies on the clock tree as defined in the device tree. This change resolves the issue with the fsl-sai audio driver.

driver core: platform: use generic driver_override infrastructure

2026-04-02T11:22:54+00:00

[ Upstream commit 2b38efc05bf7a8568ec74bfffea0f5cfa62bc01d ] When a driver is probed through __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the driver_override field without a lock, which can cause a UAF. Fix this by using the driver-core driver_override infrastructure taking care of proper locking internally. Note that calling match() from __driver_attach() without the device lock held is intentional.

clk: imx95-blk-ctl: Save/restore registers when RPM routines are called

2025-09-12T14:28:29+00:00

When runtime PM is used for clock providers that are part of a power domain, the power domain supply is cut off during runtime suspend. This causes all BLK CTL registers belonging to that power domain to reset. To prevent this, save the state of the registers before entering suspend and restore them on resume. Additionally, disable the APB clock during suspend to minimize power consumption.
