• 5323ac517   slimbus: ngd: QCOM_QMI_HELPERS has to be selected ... Browse Code »

  QCOM_QMI_HELPERS is a hidden kconfig, so the proper usage is
  to select it, not depend upon it.

  Because of this change, we now also need to depend on the same
  Kconfigs as QCOM_QMI_HELPERS depends on.

• 917809e22   slimbus: ngd: Add qcom SLIMBus NGD driver ... Browse Code »

  This patch adds suppor to Qualcomm SLIMBus Non-Generic Device (NGD)
  controller driver.
  This is light-weight SLIMBus controller driver responsible for
  communicating with slave HW directly over the bus using messaging
  interface, and communicating with master component residing on ADSP
  for bandwidth and data-channel management

  Based on intial work from
  Karthikeyan Ramasubramanian and
  Sagar Dharia

  QCOM SLIMBus controller is already under a 'if SLIMBUS' in Kconfig,
  having depends on SLIMBUS is totally redundant. Just remove it.

  Below build failure was reported on UML,
  ERROR: "devm_ioremap_resource" [drivers/slimbus/slim-qcom-ctrl.ko] undefined!
  ERROR: "__ioread32_copy" [drivers/slimbus/slim-qcom-ctrl.ko] undefined!
  ERROR: "__iowrite32_copy" [drivers/slimbus/slim-qcom-ctrl.ko] undefined!
  ERROR: "devm_ioremap" [drivers/slimbus/slim-qcom-ctrl.ko] undefined!

  This patch fixes it by making qcom slimbus depend on HAS_IOMEM, as
  these are only defined when HAS_IOMEM is selected.

  This controller driver programs manager, interface, and framer
  devices for Qualcomm's slimbus HW block.
  Manager component currently implements logical address setting,
  and messaging interface.
  Interface device reports bus synchronization information, and framer
  device clocks the bus from the time it's woken up, until clock-pause
  is executed by the manager device.

• 3648e78ec   slimbus: Add SLIMbus bus type ... Browse Code »

  SLIMbus (Serial Low Power Interchip Media Bus) is a specification
  developed by MIPI (Mobile Industry Processor Interface) alliance.
  SLIMbus is a 2-wire implementation, which is used to communicate with
  peripheral components like audio-codec.
  SLIMbus uses Time-Division-Multiplexing to accommodate multiple data
  channels, and control channel. Control channel has messages to do
  device-enumeration, messages to send/receive control-data to/from
  SLIMbus devices, messages for port/channel management, and messages to
  do bandwidth allocation.
  The framework supports multiple instances of the bus (1 controller per
  bus), and multiple slave devices per controller.

  This patch adds support to basic silmbus core which includes support to
  SLIMbus type, slimbus device registeration and some basic data structures.
