clk: imx8mq: Correct the CSI PHY sels

2026-05-23T11:04:46+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: imx8-acm: fix flags for acm clocks

2026-05-14T13:29:23+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

2026-04-02T11:09:25+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: imx8mp: inform CCF of maximum frequency of clocks

2025-05-29T09:02:33+00:00

[ Upstream commit 06a61b5cb6a8638fa8823cd09b17233b29696fa2 ] The IMX8MPCEC datasheet lists maximum frequencies allowed for different modules. Some of these limits are universal, but some depend on whether the SoC is operating in nominal or in overdrive mode. The imx8mp.dtsi currently assumes overdrive mode and configures some clocks in accordance with this. Boards wishing to make use of nominal mode will need to override some of the clock rates manually. As operating the clocks outside of their allowed range can lead to difficult to debug issues, it makes sense to register the maximum rates allowed in the driver, so the CCF can take them into account.
