soc: qcom: smd: Make callback pass channel reference

2016-04-20T02:55:12+00:00

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 Signed-off-by: Andy Gross

soc: qcom: smd: Support opening additional channels

2016-03-30T22:21:12+00:00

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. Signed-off-by: Bjorn Andersson Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: smd: Support multiple channels per sdev

2016-03-30T22:21:03+00:00

This patch allows chaining additional channels to a SMD device, enabling implementation of multi-channel SMD devies - like Bluetooth. Signed-off-by: Bjorn Andersson Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: smd: Refactor channel open and close handling

2016-03-30T22:20:57+00:00

Refactor opening and closing of channels into two separate functions instead of open coding this in the various places. Signed-off-by: Bjorn Andersson Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: smd: Split discovery and state change work

2016-03-30T22:20:51+00:00

Split the two steps of channel discovery and state change handling into two different workers. This allows for new channels to be found while we're are probing, which is required as we introduce multi-channel support.

soc: qcom: smd: Introduce callback setter

2016-03-30T22:20:43+00:00

Introduce a setter for the callback function pointer to clarify the locking around the operation and to reduce some duplication. Signed-off-by: Bjorn Andersson Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

drivers/soc/qcom/smd.c: use __ioread32_copy() instead of open-coding it

2016-01-21T01:09:18+00:00

Now that we have a generic library function for this, replace the open-coded instance. Signed-off-by: Stephen Boyd Reviewed-by: Bjorn Andersson Cc: Cc: David Howells Cc: Hauke Mehrtens Cc: Paul Walmsley Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

soc: qcom: smd: delete unneeded of_node_put

2015-10-14T19:51:22+00:00

Device node iterators perform an of_node_put on each iteration, so putting an of_node_put before a continue results in a double put. A simplified version of the semantic match that finds this problem is as follows (http://coccinelle.lip6.fr): // @@ expression root,e; local idexpression child; iterator i; @@ i(..., child, ...) { ... when != of_node_get(child) * of_node_put(child); ... * continue; } // Signed-off-by: Julia Lawall Signed-off-by: Andy Gross

soc: qcom: smd: Correct SMEM items for upper channels

2015-10-14T19:51:22+00:00

Update the SMEM items for the second set of SMD channels, as these where incorrect. Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: smd: Reject send of too big packets

2015-10-14T19:51:21+00:00

Attempting to find room for a packet that's bigger than the fifo will never succeed and the calling process will be sleeping forever in the loop, waiting for enough room. So fail early instead.
