This series sets clock parent for eMMC to the default clock parent MAIN_PLL0_HSDIV5_CLKOUT for am62, am62a, & am62p/j722s SoCs. Software (DM) does not switch MMC clock parent correctly as per the Arasan IP requirement to hold the IP in reset while clock source is switched. Since muxes to switch clock parent are not glitch-free and the default parent is tested and working fine, switch to the default as a preventative action. Changes since v1: - split original patch into three - add cover-letter - reword patch descriptions - add review tags [0] https://lore.kernel.org/linux-devicetree/20250417233040.3658761-1-jm@ti.com/ [1] https://lore.kernel.org/linux-devicetree/20250429142825.bvrbpoc5iz32wh35@garment/ Link to v1: https://lore.kernel.org/linux-devicetree/20250429142333.4140010-1-jm@ti.com/ Judith Mendez (3): arm64: dts: ti: k3-am62-main: Set eMMC clock parents to default arm64: dts: ti: k3-am62a-main: Set eMMC clock parents to default arm64: dts: ti: k3-am62p-j722s-common-main: Set eMMC clock parents to default arch/arm64/boot/dts/ti/k3-am62-main.dtsi | 2 -- arch/arm64/boot/dts/ti/k3-am62a-main.dtsi | 2 -- arch/arm64/boot/dts/ti/k3-am62p-j722s-common-main.dtsi | 2 -- 3 files changed, 6 deletions(-) base-commit: d864bb528a6725e775d564fd4430762acbb9dd0d -- 2.49.0
