fbf7e5ce - mailbox: add Samsung Exynos driver

Wed, 15 Jan 2025 14:18:15 +0000

mailbox: add Samsung Exynos driverThe Samsung Exynos mailbox controller, used on Google GS101 SoC, has 16flag bits for hardware interrupt generation and a shared register forpassing mailbox messages. When the controller is used by theACPM interface the shared register is ignored and the mailbox controlleracts as a doorbell. The controller just raises the interrupt to APMafter the ACPM interface has written the message to SRAM.Add support for the Samsung Exynos mailbox controller.Signed-off-by: Tudor Ambarus Signed-off-by: Jassi Brar List of files: /linux-6.15/drivers/mailbox/Makefile

mailbox: arm_mhu: Add ARM MHU doorbell driverThe MHU drives the signal using a 32-bit register, with all 32 bitslogically ORed together. The MHU provides a set of registers to enablesoftware to set, clear, and check the status of each of the bits of thisregister independently. The use of 32 bits for each interrupt lineenables software to provide more information about the source of theinterrupt. For example, each bit of the register can be associated witha type of event that can contribute to raising the interrupt.This patch adds a separate the MHU controller driver for doorbel modeof operation using the extended DT binding to add support the same.Signed-off-by: Sudeep Holla Signed-off-by: Jassi Brar List of files: /linux-6.15/drivers/mailbox/Makefile

The irqchip parthelps in receiving the interrupts from the IPCC clients such as modems,DSPs, PCI-E etc... and forwards them to respective entities in APSS.On the other hand, the mailbox part is used to send interrupts to the IPCCclients from the entities of APSS.Reviewed-by: Bjorn Andersson Signed-off-by: Raghavendra Rao Ananta Signed-off-by: Venkata Narendra Kumar Gutta Signed-off-by: Bjorn Andersson [mani: moved to mailbox, added static mbox channels and cleanups]Signed-off-by: Manivannan Sadhasivam Signed-off-by: Jassi Brar List of files: /linux-6.15/drivers/mailbox/Makefile

41c0e939 - mailbox: Add support for Hi3660 mailbox

Wed, 28 Feb 2018 04:54:54 +0000

mailbox: Add support for Hi3660 mailboxHi3660 mailbox controller is used to send message within multipleprocessors, MCU, HIFI, etc. It supports 32 mailbox channels and everychannel can only be used for single transferring direction. Once thechannel is enabled, it needs to specify the destination interrupt andacknowledge interrupt, these two interrupt vectors are used to createthe connection between the mailbox and interrupt controllers.The data transferring supports two modes, one is named as "automaticacknowledge" mode so after send message the kernel doesn't need to waitfor acknowledge from remote and directly return; there have another modeis to rely on handling interrupt for acknowledge.This commit is for initial version driver, which only supports"automatic acknowledge" mode to support CPU clock, which is the onlyone consumer to use mailbox and has been verified. Later may enhancethis driver for interrupt mode (e.g. for supporting HIFI).Signed-off-by: Leo Yan Signed-off-by: Ruyi Wang Signed-off-by: Kaihua Zhong Signed-off-by: Jassi Brar List of files: /linux-6.15/drivers/mailbox/Makefile
