2016-10-24soc: qcom: wcnss_ctrl: Stub wcnss_ctrl APIBjorn Andersson1-0/+13
Stub the wcnss_ctrl API to allow compile testing wcnss function drivers. Cc: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Acked-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>
2016-08-23soc: qcom: smd: Represent smd edges as devicesBjorn Andersson1-0/+18
By representing each edge as its own device the channels are no longer tied to being parented by the same smd device and as such an edge can live as children of e.g. remoteproc instances. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>
2016-08-23soc: qcom: smd: Simplify multi channel handlingBjorn Andersson1-0/+7
Multi-channel clients split between several drivers need a way to close individual channels, as these drivers might be removed individually. With this in place the responsibility of closing additionally opened channels to the client as well only concerning smd about the primary channel. With this approach we will only trigger removal of SMD devices based on the state of the primary channel, however we get in sync with how rpmsg works.

2016-08-23soc: qcom: smd: Correct compile stub prototypesBjorn Andersson1-2/+2
The prototypes for the compile stubs was not properly marked as static inline, this patch corrects this. Fixes: f79a917e69e1 ("Merge tag 'qcom-soc-for-4.7-2' into net-next") Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>
2016-06-24soc: qcom: wcnss_ctrl: Make wcnss_ctrl parent the other componentsBjorn Andersson1-0/+8
We need the signal from wcnss_ctrl indicating that the firmware is up and running before we can communicate with the other components of the chip. So make these other components children of the wcnss_ctrl device, so they can be probed in order. The process seems to take between 1/2-5 seconds, so this is done in a worker, instead of holding up the probe.

2016-05-14Merge tag 'qcom-soc-for-4.7-2' into net-nextBjorn Andersson2-1/+67
This merges the Qualcomm SOC tree with the net-next, solving the merge conflict in the SMD API between the two. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2016-05-09soc: qcom: smd: Introduce compile stubsBjorn Andersson1-1/+27
Introduce compile stubs for the SMD API, allowing consumers to be compile tested. Acked-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-20soc: qcom: smd: Make callback pass channel referenceBjorn Andersson1-2/+5
By passing the smd channel reference to the callback, rather than the smd device, we can open additional smd channels from sub-devices of smd devices. Also updates the two smd clients today found in mainline. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>
2016-03-31soc: qcom: smd: Support opening additional channelsBjorn Andersson1-0/+4
With the qcom_smd_open_channel() API we allow SMD devices to open additional SMD channels, to allow implementation of multi-channel SMD devices - like Bluetooth. Channels are opened from the same edge as the calling SMD device is tied to.

2016-03-31soc: qcom: smd: Introduce callback setterBjorn Andersson1-1/+3
Introduce a setter for the callback function pointer to clarify the locking around the operation and to reduce some duplication.

2015-12-08soc: qcom: Introduce common SMEM state machine codeBjorn Andersson1-0/+18
This implements a common API for handling and exposing SMP2P and SMSM state information. Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> Signed-off-by: Andy Gross <agross@codeaurora.org>
2015-10-14soc: qcom: Make qcom_smem_get() return a pointerStephen Boyd1-1/+1
Passing a void ** almost always requires a cast at the call site. Instead of littering the code with casts every time this function is called, have qcom_smem_get() return a void pointer to the location of the smem item. This frees the caller from having to cast the pointer.

2015-10-14soc: qcom: smd: Implement id_table driver matchingBjorn Andersson1-0/+11
Implement a id_table based driver maching mechanism for drivers that binds to fixed channels and doesn't need any additional configuration, e.g. IPCRTR and DIAG. Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> Signed-off-by: Andy Gross <agross@codeaurora.org>
2015-07-29soc: qcom: Driver for the Qualcomm RPM over SMDBjorn Andersson1-0/+35
Driver for the Resource Power Manager (RPM) found in Qualcomm 8974 based devices. The driver exposes resources that child drivers can operate on; to implementing regulator, clock and bus frequency drivers.
