📝 Walkthrough

Walkthrough

This patch updates the Meson-AXG device tree source to configure MMC controller clock phases and assigned clock rates. The changes add MMC phase bindings, set core phase to CLK_PHASE_270, and assign the SD/eMMC clock to 24000000 Hz for both sd_emmc_b and sd_emmc_c controllers.

Changes

Cohort / File(s)	Summary
Meson-AXG DTS MMC Configuration arch/arm64/boot/dts/amlogic/meson-axg.dtsi	Added include directive for MMC phase clock binding constants; configured amlogic,mmc-phase properties with CLK_PHASE_270 core phase for both sd_emmc_b and sd_emmc_c nodes; assigned clock rates to 24000000 via assigned-clocks and assigned-clock-rates properties.

Poem

A rabbit hops through device trees so grand,
With phase shifts and clocks in each hand,
MMC controllers now dance just right,
At 24 MHz, clear and bright! 🐰⏱️
