| |
From: Ciprian Marian Costea <ciprianmarian.costea@oss.nxp.com>
Add support for the uSDHC controller found in NXP S32N79 automotive SoCs, which reuse the existing sdhci-esdhc-imx driver with slice difference.
Compared with s32g2/s32g3, needn't set ESDHC_FLAG_SKIP_CD_WAKE flag because s32n79 does not have this limitation.
