From 2508925fb346661bad9f50b497d7ac7d0b6085d0 Mon Sep 17 00:00:00 2001 From: Andy-ld Lu andy-ld.lu@mediatek.com Date: Mon, 11 Nov 2024 16:49:31 +0800 Subject: [PATCH] mmc: mtk-sd: Fix MMC_CAP2_CRYPTO flag setting

Currently, the MMC_CAP2_CRYPTO flag is set by default for eMMC hosts. However, this flag should not be set for hosts that do not support inline encryption.

The 'crypto' clock, as described in the documentation, is used for data encryption and decryption. Therefore, only hosts that are configured with this 'crypto' clock should have the MMC_CAP2_CRYPTO flag set.
