mailbox: Add Platform Message-Handling-Unit variant driver

2016-09-07T07:37:17Z

Add Message-Handling-Unit driver for platform variants as mailbox controller. Actually, only the Amlogic Meson GXBB SoC MHU is supported. Signed-off-by: Neil Armstrong Signed-off-by: Jassi Brar

mailbox: Add Broadcom PDC mailbox driver

mailbox: Introduce TI message manager driver

2016-03-21T15:03:15Z

Support for TI Message Manager Module. This hardware block manages a bunch of hardware queues meant for communication between processor entities. Clients sitting on top of this would manage the required protocol for communicating with the counterpart entities. For more details on TI Message Manager hardware block, see documentation that will is available here: http://www.ti.com/lit/ug/spruhy8/spruhy8.pdf Chapter 8.1(Message Manager) Signed-off-by: Nishanth Menon Signed-off-by: Jassi Brar

mailbox: rockchip: Add Rockchip mailbox driver

2016-03-11T03:40:06Z

This driver is found on RK3368 SoCs. The Mailbox module is a simple APB peripheral that allows both the Cortex-A53 MCU system to communicate by writing operation to generate interrupt. The registers are accessible by both CPU via APB interface. The Mailbox has the following main features: 1) Support dual-core system: Cortex-A53 and MCU. 2) Support APB interface. 3) Support four mailbox elements, each element includes one data word, one command word register and one flag bit that can represent one interrupt. 4) Four interrupts to Cortex-A53. 5) Four interrupts to MCU. 6) Provide 32 lock registers for software to use to indicate whether mailbox is occupied.

mailbox: Hi6220: add mailbox driver

2016-03-04T07:02:20Z

Add driver for Hi6220 mailbox, the mailbox communicates with MCU; for sending data, it can support two methods for low level implementation: one is to use interrupt as acknowledge, another is automatic mode which without any acknowledge. These two methods have been supported in the driver. For receiving data, it will depend on the interrupt to notify the channel has incoming message. Now mailbox driver is used to send message to MCU to control dynamic voltage and frequency scaling for CPU, GPU and DDR. Signed-off-by: Leo Yan Signed-off-by: Jassi Brar

mailbox: Add support for APM X-Gene platform mailbox driver

2016-02-15T07:50:03Z

X-Gene mailbox controller provides 8 mailbox channels, with each channel has a dedicated interrupt line. Signed-off-by: Feng Kan Signed-off-by: Duc Dang Signed-off-by: Jassi Brar

mailbox: Add generic mechanism for testing Mailbox Controllers

2015-10-17T05:06:56Z

This particular Client implementation uses shared memory in order to pass messages between Mailbox users; however, it can be easily hacked to support any type of Controller. Signed-off-by: Lee Jones Signed-off-by: Jassi Brar

mailbox: Add support for ST's Mailbox IP

2015-10-17T05:06:56Z

ST's platforms currently support a maximum of 5 Mailboxes, one for each of the supported co-processors situated on the platform. Each Mailbox is divided up into 4 instances which consist of 32 channels. Messages are passed between the application and co-processors using shared memory areas. It is the Client's responsibility to manage these areas. Signed-off-by: Lee Jones Signed-off-by: Jassi Brar

mailbox: Enable BCM2835 mailbox support

2015-06-11T16:49:40Z

This mailbox driver provides a single mailbox channel to write 32-bit values to the VPU and get a 32-bit response. The Raspberry Pi firmware uses this mailbox channel to implement firmware calls, while Roku 2 (despite being derived from the same firmware tree) doesn't. The driver was originally submitted by Lubomir, based on the out-of-tree 2708 mailbox driver. Eric Anholt fixed it up for upstreaming, with the major functional change being that it now has no notion of multiple channels (since that is a firmware-dependent concept) and instead the raspberrypi-firmware driver will do that bit-twiddling in its own messages.
