Hello, Mediatek eMMC hardware IP has Inline Crypto Engine (ICE), we support inline encryption now. For Inline Crypto Engine (ICE), see: - https://lore.kernel.org/linux-arm-msm/ 20210126001456.382989-2-ebiggers@xxxxxxxxxx/T/ This patchset supports Mediatek eMMC inline encryption which meets the upcoming version of the eMMC specification such as v5.1 or v5.2. Patch 1-2, add crypto property and crypto clock, patch 3, document the device tree description about crypto clock. Please noted that there is a special way of on/off crypto hardware IP in our SoCs, the enable bit must be controlled under ARM highest security level, that means must in ARM trusted firmware(ATF). Changed in v3: - Removed "mmc: Mediatek: enable crypto hardware engine" patch temporarily. Needs finding a better way for enable crypto hardware IP through ATF, so remove "mmc: Mediatek: enable crypto hardware engine" patch temporarily, we could enable it in ATF directly when boot up which will be a workaround solution. Discussing about this, see: https://lore.kernel.org/linux-mmc/ YE%2Fnfu8vRETYN9dO@xxxxxxxxx/T/#t - We will put the above mentioned patch in a single patch Peng Zhou (3): mmc: Mediatek: add Inline Crypto Engine support arm64: dts: Mediatek: MT6779: add mmc node with ICE setting dt-bingdings: mmc: Mediatek: add ICE clock Documentation/devicetree/bindings/mmc/mtk-sd.yaml | 6 ++++-- arch/arm64/boot/dts/mediatek/mt6779.dtsi | 14 ++++++++++++++ drivers/mmc/host/mtk-sd.c | 15 ++++++++++++++- 3 files changed, 32 insertions(+), 3 deletions(-)
