2024-10-30mmc: sdhci: Make MMC_SDHCI_UHS2 config symbol invisibleGeert Uytterhoeven1-1/+1
There is no need to ask the user about enabling UHS-II support, as all drivers that support UHS2-capable devices already select MMC_SDHCI_UHS2. Hence make the symbol invisible, unless when compile-testing.

2024-10-14mmc: mtk-sd: Implement Host Software Queue for eMMC and SD CardAngeloGioacchino Del Regno1-0/+1
Add support for Host Software Queue (HSQ) and enable it when the controller instance does not have Command Queue Engine HW support. It was chosen to enable HSQ only for eMMC and SD/MicroSD cards and not for SDIO as performance improvements are seen only for the former. Performance was measured with a SanDisk Extreme Ultra A2 MicroSD card in a MediaTek MT8195T Acer Chromebook Spin 513 (CP513-2H), by running FIO (bs=4k) on an ArchLinux userspace. ....

ARCH_RENESAS MMC_SDHI_INTERNAL_DMAC config option has dependency on ARM64 and R7S9210/R8A77470 this dependency will keep growing for future SoCs for varying architectures. So to simplify this configuration make MMC_SDHI_INTERNAL_DMAC solely depend on ARCH_RENESAS, as all Renesas SoCs inherently depend on the ARCH_RENESAS config option. This allows selecting MMC_SDHI_INTERNAL_DMAC config option for RZ/Five SoC which is based on RISC-V architecture.

au1xmmc is split somewhat awkwardly into the main mmc subsystem driver, and callbacks in platform_data that sit under arch/mips/ and are always built in. The latter than call mmc_detect_change through symbol_get. Remove the use of symbol_get by requiring the driver to be built in. In the future the interrupt handlers for card insert/eject detection should probably be moved into the main driver, and which point it can be built modular again.

2023-06-12mmc: sdhci-msm: Switch to the new ICE APIAbel Vesa1-1/+1
Now that there is a new dedicated ICE driver, drop the sdhci-msm ICE implementation and use the new ICE api provided by the Qualcomm soc driver ice. The platforms that already have ICE support will use the API as library since there will not be a devicetree node, but instead they have reg range. In this case, the of_qcom_ice_get will return an ICE instance created for the consumer's device. But if there are platforms that do not have ice reg in the consumer devicetree node and instead provide a dedicated ICE devicetree node, theof_qcom_ice_get will look up the device based on qcom,ice property and will get the ICE instance registered by the probe function of the ice driver. The ICE clock is now handle by the new driver. This is done by enabling it on the creation of the ICE instance and then enabling/disabling it on SDCC runtime resume/suspend.

While the sdhci-of-aspeed KUnit tests do work when builtin, and do work when KUnit itself is being built as a module, the two together break. This is because the KUnit tests (understandably) depend on KUnit, so a built-in test cannot build if KUnit is a module. Fix this by adding a dependency on (MMC_SDHCI_OF_ASPEED=m || KUNIT=y), which only excludes this one problematic configuration.

The kunit_test_suite() macro is no-longer incompatible with module_add, so its use can be reinstated. Since this fixes parsing with builtins and kunit_tool, also enable the test by default when KUNIT_ALL_TESTS is enabled. The test can now be run via kunit_tool with: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_OF=y --kconfig_add CONFIG_OF_ADDRESS=y \ --kconfig_add CONFIG_MMC=y --kconfig_add CONFIG_MMC_SDHCI=y \ --kconfig_add CONFIG_MMC_SDHCI_PLTFM=y \ --kconfig_add CONFIG_MMC_SDHCI_OF_ASPEED=y \ 'sdhci-of-aspeed' (It may be worth adding a .kunitconfig at some point, as there are enough dependencies to make that command scarily long.)

2022-05-16m68k: coldfire: drop ISA_DMA_API supportArnd Bergmann1-1/+1
After a build regression report, I took a look at possible users of CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement ISA_DMA_API, and is clearly not used on the platforms with ISA support. The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded, but this is less clear. Unlike other PCMCIA implementations, this one does not use the drivers/pcmcia subsystem at all and just supports the "apne" network driver. When it was first added, one could use ISA drivers on it as well, but this probably broke at some point. With no reason to keep this, let's just drop the corresponding files and prevent the remaining ISA drivers that use this from getting built. The remaining definitions in asm/dma.h are used for PCI support.

2021-11-23clk: sunxi-ng: Allow the CCU core to be built as a moduleSamuel Holland1-0/+1
Like the individual CCU drivers, it can be beneficial for memory consumption of cross-platform configurations to only load the CCU core on the relevant platform. For example, a generic arm64 kernel sees the following improvement when building the CCU core and drivers as modules: before: text data bss dec hex filename 13882360 5251670 360800 19494830 12977ae vmlinux after: text data bss dec hex filename 13734787 5086442 360800 19182029 124b1cd vmlinux So the result is a 390KB total reduction in kernel image size. The one early clock provider (sun5i) requires the core to be built in. Now that loading the MMC driver will trigger loading the CCU core, the MMC timing mode functions do not need a compile-time fallback.

2021-10-07qcom_scm: hide Kconfig symbolArnd Bergmann1-1/+1
Now that SCM can be a loadable module, we have to add another dependency to avoid link failures when ipa or adreno-gpu are built-in: aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe': ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available' ld.lld: error: undefined symbol: qcom_scm_is_available >>> referenced by adreno_gpu.c >>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a This can happen when CONFIG_ARCH_QCOM is disabled and we don't select QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.

Honestly though that's just a bunch of data so the diffstat reflects that. Looking beyond that there's just a bunch of updates all around in various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall the driver changes look to be mostly enabling more clks and non-critical fixes that we could hold until the next merge window. I'm especially excited about the series from Arnd that graduates clkdev to be the only implementation of clk_get() and clk_put(). That's a good step in the right direction to migreate eveerything over to the common clk framework. Now we don't have to worry about clkdev specific details, they're just part of the clk API now.

2021-02-01mmc: sdhci-msm: add Inline Crypto Engine supportEric Biggers1-0/+1
Add support for Qualcomm Inline Crypto Engine (ICE) to sdhci-msm. The standard-compliant parts, such as querying the crypto capabilities and enabling crypto for individual MMC requests, are already handled by cqhci-crypto.c, which itself is wired into the blk-crypto framework. However, ICE requires vendor-specific init, enable, and resume logic, and it requires that keys be programmed and evicted by vendor-specific SMC calls. Make the sdhci-msm driver handle these details. This is heavily inspired by the similar changes made for UFS, since the UFS and eMMC ICE instances are very similar. See commit df4ec2fa7a4d ("scsi: ufs-qcom: Add Inline Crypto Engine support"). I tested this on a Sony Xperia 10, which uses the Snapdragon 630 SoC, which has basic upstream support. Mainly, I used android-xfstests (https://github.com/tytso/xfstests-bld/blob/master/Documentation/android-xfstests.md) to run the ext4 and f2fs encryption tests in a Debian chroot: android-xfstests -c ext4,f2fs -g encrypt -m inlinecrypt These tests included tests which verify that the on-disk ciphertext is identical to that produced by a software implementation. I also verified that ICE was actually being used.
