[PATCH 0/4] mmc: spacemit: Introduce two DT properties

From: Yixun Lan

Date: Wed Sep 02 2026 - 03:09:04 EST


In this series, we try to introduce two DT properties for SpacemiT
SDHCI driver, A clock-frequency property to configure the rate
of io clock, which needed to configure for SDIO mode. The tx delay
property is used to configure the step count of TX delay line,
which is needed due to varous hardware layout has different
tuning settings.
