a24015fa - firmware: imx: Move i.MX SCU soc driver into imx firmware folder

Thu, 25 Jun 2020 21:14:07 +0000

firmware: imx: Move i.MX SCU soc driver into imx firmware folderThe i.MX SCU soc driver depends on SCU firmware driver, so it has touse platform driver model for proper defer probe operation, sinceit has no device binding in DT file, a simple platform device iscreated together inside the platform driver. To make it more clean,we can just move the entire SCU soc driver into imx firmware folderand initialized by i.MX SCU firmware driver.Signed-off-by: Anson Huang Signed-off-by: Shawn Guo List of files: /linux-6.15/drivers/firmware/imx/Makefile

ffbf23d5 - firmware: imx: Add DSP IPC protocol interface

Thu, 01 Aug 2019 09:56:36 +0000

firmware: imx: Add DSP IPC protocol interfaceSome of i.MX8 processors (e.g i.MX8QM, i.MX8QXP) containthe Tensilica HiFi4 DSP for advanced pre- and post-audioprocessing.The communication between Host CPU and DSP firmware istaking place using a shared memory area for message passingand a dedicated Messaging Unit for notifications.DSP IPC protocol offers a doorbell interface usingimx-mailbox API.We use 4 MU channels (2 x TXDB, 2 x RXDB) to implement arequest-reply protocol.Connection 0 (txdb0, rxdb0): - Host writes messasge to shared memory [SHMEM] - Host sends a request [MU] - DSP handles request [SHMEM] - DSP sends reply [MU]Connection 1 (txdb1, rxdb1): - DSP writes a message to shared memory [SHMEM] - DSP sends a request [MU] - Host handles request [SHMEM] - Host sends reply [MU]The protocol interface will be used by a Host client tocommunicate with the DSP. First client will be the i.MX8part from Sound Open Firmware infrastructure.The protocol offers the following interface:On Tx: - imx_dsp_ring_doorbell, will be called to notify the DSP that it needs to handle a request.On Rx: - clients need to provide two callbacks: .handle_reply .handle_request - the callbacks will be used by the protocol on notification arrival from DSP.Signed-off-by: Daniel Baluta Reviewed-by: Oleksij Rempel Signed-off-by: Shawn Guo List of files: /linux-6.15/drivers/firmware/imx/Makefile

851826c7 - firmware: imx: enable imx scu general irq function

Tue, 09 Apr 2019 04:59:55 +0000

firmware: imx: enable imx scu general irq functionThe System Controller Firmware (SCFW) controls RTC, thermaland WDOG etc., these resources' interrupt function are managedby SCU. When any IRQ pending, SCU will notify Linux via MU generalinterrupt channel #3, and Linux kernel needs to call SCU APIsto get IRQ status and notify each module to handle the interrupt.Since there is no data transmission for SCU IRQ notification, sodoorbell mode is used for this MU channel, and SCU driver willuse notifier mechanism to broadcast to every module which registersthe SCU block notifier.Signed-off-by: Anson Huang Reviewed-by: Dong Aisheng Signed-off-by: Shawn Guo List of files: /linux-6.15/drivers/firmware/imx/Makefile

c800cd78 - firmware: imx: add SCU power domain driver

Thu, 01 Nov 2018 15:20:13 +0000

firmware: imx: add SCU power domain driverSome i.MX SoCs contain a system controller that is responsible forcontrolling the state of the IPs that are present. Communicationbetween the host processor running an OS and the system controllerhappens through a SCU protocol. This patch adds SCU protocol basedpower domains drivers.Cc: Ulf Hansson Cc: Rob Herring Cc: Shawn Guo Cc: Sascha Hauer Cc: Fabio Estevam Cc: "Rafael J.

Sun, 07 Oct 2018 13:04:42 +0000

firmware: imx: add SCU firmware driver supportThe System Controller Firmware (SCFW) is a low-level system functionwhich runs on a dedicated Cortex-M core to provide power, clock, andresource management. It exists on some i.MX8 processors. e.g. i.MX8QM(QM, QP), and i.MX8QX (QXP, DX).This patch implements the SCU firmware IPC function and the commonmessage sending API sc_call_rpc.Cc: Shawn Guo Cc: Fabio Estevam Cc: Jassi Brar Reviewed-by: Sascha Hauer Signed-off-by: Dong Aisheng Signed-off-by: Shawn Guo List of files: /linux-6.15/drivers/firmware/imx/Makefile
