abb9c9b8 - slimbus: stream: add stream support

Thu, 05 Jul 2018 13:54:25 +0000

slimbus: stream: add stream supportThis patch adds support to SLIMbus stream apis for slimbus device.SLIMbus streaming involves adding support to Data Channel Management andchannel Reconfiguration Messages to slim core plus few stream apis.>From slim device side the apis are very simple mostly inline with otherstream apis.Currently it only supports Isochronous and Push/Pull transport protocols,which are sufficient for audio use cases.Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/slimbus/Makefile

917809e2 - slimbus: ngd: Add qcom SLIMBus NGD driver

Tue, 19 Jun 2018 16:13:01 +0000

slimbus: ngd: Add qcom SLIMBus NGD driverThis patch adds suppor to Qualcomm SLIMBus Non-Generic Device (NGD)controller driver.This is light-weight SLIMBus controller driver responsible forcommunicating with slave HW directly over the bus using messaginginterface, and communicating with master component residing on ADSPfor bandwidth and data-channel managementBased on intial work fromKarthikeyan Ramasubramanian andSagar Dharia Signed-off-by: Srinivas Kandagatla Tested-by: Craig Tatlor Reviewed-by: Vinod Koul Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/slimbus/Makefile

ad7fcbc3 - slimbus: qcom: Add Qualcomm Slimbus controller driver

Mon, 11 Dec 2017 23:43:05 +0000

slimbus: qcom: Add Qualcomm Slimbus controller driverThis controller driver programs manager, interface, and framerdevices for Qualcomm's slimbus HW block.Manager component currently implements logical address setting,and messaging interface.Interface device reports bus synchronization information, and framerdevice clocks the bus from the time it's woken up, until clock-pauseis executed by the manager device.Signed-off-by: Sagar Dharia Signed-off-by: Srinivas Kandagatla Reviwed-by: Mark Brown Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/slimbus/Makefile

4b14e62a - slimbus: Add support for 'clock-pause' feature

Mon, 11 Dec 2017 23:43:01 +0000

slimbus: Add support for 'clock-pause' featurePer SLIMbus specification, a reconfiguration sequence known as'clock pause' needs to be broadcast over the bus while entering low-power mode. Clock-pause is initiated by the controller driver.To exit clock-pause, controller typically wakes up the framer device.Since wakeup precedure is controller-specific, framework calls it viacontroller's function pointer to invoke it.Signed-off-by: Sagar Dharia Signed-off-by: Srinivas Kandagatla Reviwed-by: Mark Brown Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/slimbus/Makefile

afbdcc7c - slimbus: Add messaging APIs to slimbus framework

Mon, 11 Dec 2017 23:43:00 +0000

slimbus: Add messaging APIs to slimbus frameworkSLIMbus devices use value-element, and information elements tocontrol device parameters (e.g. value element is used to representgain for codec, information element is used to represent interruptstatus for codec when codec interrupt fires).Messaging APIs are used to set/get these value and informationelements. SLIMbus specification uses 8-bit "transaction IDs" formessages where a read-value is anticipated. Framework uses a tableof pointers to store those TIDs and responds back to the caller inO(1).Caller can do synchronous and asynchronous reads/writes.Signed-off-by: Srinivas Kandagatla Reviwed-by: Mark Brown Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/slimbus/Makefile

3648e78e - slimbus: Add SLIMbus bus type

Mon, 11 Dec 2017 23:42:57 +0000

slimbus: Add SLIMbus bus typeSLIMbus (Serial Low Power Interchip Media Bus) is a specificationdeveloped by MIPI (Mobile Industry Processor Interface) alliance.SLIMbus is a 2-wire implementation, which is used to communicate withperipheral components like audio-codec.SLIMbus uses Time-Division-Multiplexing to accommodate multiple datachannels, and control channel. Control channel has messages to dodevice-enumeration, messages to send/receive control-data to/fromSLIMbus devices, messages for port/channel management, and messages todo bandwidth allocation.The framework supports multiple instances of the bus (1 controller perbus), and multiple slave devices per controller.This patch adds support to basic silmbus core which includes support toSLIMbus type, slimbus device registeration and some basic data structures.Signed-off-by: Sagar Dharia Signed-off-by: Srinivas Kandagatla Reviwed-by: Mark Brown Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/slimbus/Makefile
