Changes in Kconfig

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/Kconfig

bb538eff - soc: apple: rtkit: Port to the internal mailbox driver

Tue, 14 Mar 2023 10:46:47 +0000

soc: apple: rtkit: Port to the internal mailbox driverNow that we have a mailbox driver in drivers/soc/apple, port the RTKitcode to it. This mostly just entails replacing calls through the mailboxsubsystem with direct calls into the driver.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/Kconfig

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/Kconfig

1bfadf2e - pmdomain: apple: Move Kconfig option to the pmdomain subsystem

Mon, 11 Sep 2023 22:13:37 +0000

pmdomain: apple: Move Kconfig option to the pmdomain subsystemThe Kconfig option belongs closer to the corresponding implementation,hence let's move it from the soc subsystem to the pmdomain subsystem.Cc: Hector Martin Cc: Sven Peter Cc: Alyssa Rosenzweig Cc: Reviewed-by: Eric Curtin Reviewed-by: Neal Gompa Signed-off-by: Ulf Hansson List of files: /linux-6.15/drivers/soc/apple/Kconfig

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/Kconfig

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/Kconfig

soc: apple: apple-pmgr-pwrstate: Do not build as a moduleThis doesn't make any sense as a module since it is a critical device,and it turns out of_phandle_iterator_args was not exported so the moduleversion doesn't build anyway.Fixes: 6df9d38f9146 ("soc: apple: Add driver for Apple PMGR power state controls")Reported-by: kernel test robot Reviewed-by: Sven Peter Signed-off-by: Hector Martin List of files: /linux-6.15/drivers/soc/apple/Kconfig

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/Kconfig
