The reason for this is because, staring with SM8550, the ICE IP block is shared between UFS and SDCC, which means we need to probe a dedicated device and share it between those two consumers. So let's add the ICE dedicated driver as a soc driver. Signed-off-by: Abel Vesa --- Changes since v1: * renamed filename to simply ice.c * kept all the copyrights from UFS and SDHC drivers * Used GENMASK like Konrad suggested * Fixed the comment about "ICE instance is supported currently", like Konrad suggested * Used FIELD_GET * Dropped extra comment from qcom_ice_low_power_mode_enable * Used lowercase in hex values * Dropped double space from comment above the qcom_ice_program_key function * Changed the dev_info about engine being registered to dev_dbg * Made the compatible entry in the match table a single line * Made the qcom_ice_driver definition consistent with respect to spaces/tabs * Switched QCOM_INLINE_CRYPTO_ENGINE to tristate and made it built-in if any of the UFS or the SDHC drivers are built-in. This is to allow the API to be available even if the built-in driver doesn't have crypto enabled. * Dropped the engine container state. The of_qcom_ice_get will look up the ICE device based on the phandle and get the ICE data from dev data. * Dropped the supported field from qcom_ice definition. * Marked all funtions that are local as static. * Replaced qcom_ice_wait_bist_status function implementation with the one dropped from sdhci-msm.c * Added a separate function for key eviction drivers/soc/qcom/Kconfig | 6 + drivers/soc/qcom/Makefile | 1 + drivers/soc/qcom/ice.c | 301 ++++++++++++++++++++++++++++++++++++++ include/soc/qcom/ice.h | 65 ++++++++ 4 files changed, 373 insertions(+) create mode 100644 drivers/soc/qcom/ice.c create mode 100644 include/soc/qcom/ice.h diff --git a/drivers/soc/qcom/Kconfig b/drivers/soc/qcom/Kconfig index a8f283086a21..c584369e9810 100644 --- a/drivers/soc/qcom/Kconfig +++ b/drivers/soc/qcom/Kconfig @@ -275,4 +275,10 @@ config QCOM_ICC_BWMON the fixed bandwidth votes from cpufreq (CPU nodes) thus achieve high memory throughput even with lower CPU frequencies. +config QCOM_INLINE_CRYPTO_ENGINE + tristate + depends on SCSI_UFS_CRYPTO || MMC_CRYPTO + default y if SCSI_UFS_QCOM=y || MMC_SDHCI_MSM=y + select QCOM_SCM + endmenu diff --git a/drivers/soc/qcom/Makefile b/drivers/soc/qcom/Makefile index 6e88da899f60..0f43a88b4894 100644 --- a/drivers/soc/qcom/Makefile +++ b/drivers/soc/qcom/Makefile @@ -32,3 +32,4 @@ obj-$(CONFIG_QCOM_RPMHPD) += rpmhpd.o obj-$(CONFIG_QCOM_RPMPD) += rpmpd.o obj-$(CONFIG_QCOM_KRYO_L2_ACCESSORS) += kryo-l2-accessors.o obj-$(CONFIG_QCOM_ICC_BWMON) += icc-bwmon.o +obj-$(CONFIG_QCOM_INLINE_CRYPTO_ENGINE) += ice.o diff --git a/drivers/soc/qcom/ice.c b/drivers/soc/qcom/ice.c new file mode 100644 index 000000000000..ae354e110dc0 --- /dev/null +++ b/drivers/soc/qcom/ice.c @@ -0,0 +1,301 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Qualcomm ICE (Inline Crypto Engine) support. + * + * Copyright (c) 2013-2019, The Linux Foundation.

On most platforms, there is only one ICE instance, used by either UFS or SDCC, but there are some platforms that have two separate instances and, therefore, two separate nodes are added. Signed-off-by: Abel Vesa --- Changes since v1: * Made changes for all platforms that use ICE, as a single patch since most changes look really similar. arch/arm64/boot/dts/qcom/sdm630.dtsi | 18 +++++++++----- arch/arm64/boot/dts/qcom/sdm670.dtsi | 15 +++++++---- arch/arm64/boot/dts/qcom/sdm845.dtsi | 21 +++++++++------- arch/arm64/boot/dts/qcom/sm6115.dtsi | 37 +++++++++++++++++----------- arch/arm64/boot/dts/qcom/sm6350.dtsi | 31 ++++++++++++++--------- arch/arm64/boot/dts/qcom/sm8150.dtsi | 21 +++++++++------- arch/arm64/boot/dts/qcom/sm8450.dtsi | 22 ++++++++++------- 7 files changed, 102 insertions(+), 63 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sdm630.dtsi b/arch/arm64/boot/dts/qcom/sdm630.dtsi index 5827cda270a0..2aed49104d9d 100644 --- a/arch/arm64/boot/dts/qcom/sdm630.dtsi +++ b/arch/arm64/boot/dts/qcom/sdm630.dtsi @@ -1330,9 +1330,8 @@ opp-200000000 { sdhc_1: mmc@c0c4000 { compatible = "qcom,sdm630-sdhci", "qcom,sdhci-msm-v5";
