c84292d9 - soc: apple: mailbox: Rename config symbol to APPLE_MAILBOX

Tue, 28 Mar 2023 11:38:26 +0000

soc: apple: mailbox: Rename config symbol to APPLE_MAILBOXWith the original owner of APPLE_MAILBOX removed, let's rename the newAPPLE_MBOX to the old name. This avoids .config churn for downstreamusers, and leaves us with an identical config symbol and module name asbefore.Acked-by: Eric Curtin Acked-by: Neal Gompa Acked-by: Alyssa Rosenzweig Signed-off-by: Hector Martin List of files: /linux-6.15/drivers/soc/apple/Makefile

6e1457fc - soc: apple: mailbox: Add ASC/M3 mailbox driver

Tue, 14 Mar 2023 10:45:45 +0000

soc: apple: mailbox: Add ASC/M3 mailbox driverThis new driver is based on the existing apple-mailbox driver, butreplaces the usage of the mailbox subsystem with directly exportedsymbols.As part of this refactor, this adds support for using the hardware FIFOs(not supported in mailbox) and implicitly fixes a bunch of bugs causedby bad interactions with the mailbox subsystem. It also adds runtime-PMsupport.The new config symbol is APPLE_MBOX, while the module name remainsidentical ("apple-mailbox"). The configs are mutually exclusive inKconfig, to avoid conflicts.Acked-by: Eric Curtin Acked-by: Neal Gompa Acked-by: Alyssa Rosenzweig Signed-off-by: Hector Martin List of files: /linux-6.15/drivers/soc/apple/Makefile

869b9dd3 - soc: apple: Move power-domain driver to the genpd dir

Tue, 04 Jul 2023 22:06:27 +0000

soc: apple: Move power-domain driver to the genpd dirTo simplify with maintenance let's move the apple power-domain driver tothe new genpd directory. Going forward, patches are intended to be managedthrough a separate git tree, according to MAINTAINERS.Cc: Hector Martin Cc: Sven Peter Cc: Alyssa Rosenzweig Cc: Signed-off-by: Ulf Hansson List of files: /linux-6.15/drivers/soc/apple/Makefile

b170143a - soc: apple: Add SART driver

Sun, 01 May 2022 14:55:08 +0000

soc: apple: Add SART driverThe NVMe co-processor on the Apple M1 uses a DMA address filter calledSART for some DMA transactions. This adds a simple driver used toconfigure the memory regions from which DMA transactions are allowed.Unlike a real IOMMU, SART does not support any pagetables and can't beimplemented inside the IOMMU subsystem using iommu_ops.It also can't be implemented using dma_map_ops since not all DMAtransactions of the NVMe controller are filtered by SART.Instead, most buffers have to be registered using the integrated NVMeIOMMU and we can't have two separate dma_map_ops implementations for asingle device.Co-developed-by: Hector Martin Reviewed-by: Arnd Bergmann Signed-off-by: Hector Martin Signed-off-by: Sven Peter List of files: /linux-6.15/drivers/soc/apple/Makefile

9bd1d9a0 - soc: apple: Add RTKit IPC library

Sun, 01 May 2022 14:55:06 +0000

soc: apple: Add RTKit IPC libraryApple SoCs such as the M1 come with multiple embedded co-processorsrunning proprietary firmware. Communication with those is establishedover a simple mailbox using the RTKit IPC protocol.This cannot be implemented inside the mailbox subsystem since on topof communication over channels we also need support for starting,hibernating and resetting these co-processors. We also need tohandle shared memory allocations differently depending on theco-processor and don't want to split that across multiple drivers.Reviewed-by: Arnd Bergmann Signed-off-by: Sven Peter List of files: /linux-6.15/drivers/soc/apple/Makefile

6df9d38f - soc: apple: Add driver for Apple PMGR power state controls

Wed, 24 Nov 2021 07:34:18 +0000

soc: apple: Add driver for Apple PMGR power state controlsImplements genpd and reset providers for downstream devices. Eachinstance of the driver binds to a single register and represents asingle SoC power domain.The driver does not currently implement all features (clockgate-onlystate, misc flags), but we declare the respective registers fordocumentation purposes. These features will be added as they becomeuseful for downstream devices.This also creates the apple/soc tree and Kconfig submenu.Acked-by: Linus Walleij Signed-off-by: Hector Martin List of files: /linux-6.15/drivers/soc/apple/Makefile
