slimbus: qcom: remove unused qcom controller driver

2025-09-12T13:47:37+00:00

Qcom Slimbus controller driver is totally unused and dead code, there is no point in keeping this driver in the kernel without users. This patch removes the driver along with device tree bindings.

slimbus: qcom-ngd-ctrl: allow compile testing without QCOM_RPROC_COMMON

2022-09-24T12:51:53+00:00

The Qualcomm common remote-proc code (CONFIG_QCOM_RPROC_COMMON) has necessary stubs, so it is not needed for compile testing.

slimbus: qcom-ngd-ctrl: fix SSR dependencies

2020-12-09T18:57:03+00:00

NGD should depend on QCOM_RPROC_COMMON instead of selecting it, as this will be selected by respective remoteproc driver.

slimbus: qcom-ngd-ctrl: add Protection Domain Restart Support

Add support to protection domain restart. Protection domain restart would also restart the service just like SSR. Signed-off-by: Srinivas Kandagatla Link: https://lore.kernel.org/r/20201127102451.17114-4-srinivas.kandagatla@linaro.org Signed-off-by: Greg Kroah-Hartman

slimbus: qcom-ngd-ctrl: add Sub System Restart support

2020-11-27T15:03:42+00:00

This patch adds SSR(SubSystem Restart) support which includes, synchronisation between SSR and QMI server notifications. Also with this patch now NGD is taken down by SSR instead of QMI server down notification. NGD up path now relies on both SSR and QMI notifications and particularly sequence of SSR up followed by QMI server up notification.

slimbus: ngd: QCOM_QMI_HELPERS has to be selected

2018-11-27T07:44:06+00:00

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. Signed-off-by: Niklas Cassel Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

slimbus: ngd: Add qcom SLIMBus NGD driver

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 Signed-off-by: Srinivas Kandagatla Tested-by: Craig Tatlor Reviewed-by: Vinod Koul Signed-off-by: Greg Kroah-Hartman
