remoteproc: qcom: mdt_loader: Use signed type for offset

2017-02-22T10:07:13+00:00

In the transition from using rproc_da_to_va(), the type of the load offset became unsigned. This causes the subsequent check to let negative values less than p_memsz + mem_size through and we write outside of the buffer. Change the type back to a signed value to catch this.

remoteproc: Move qcom_mdt_loader into drivers/soc/qcom

2017-02-06T16:57:25+00:00

With the remoteproc parts cleaned out of the MDT loader we can move it to drivers/soc/qcom. Acked-by: Andy Gross Signed-off-by: Bjorn Andersson

soc: qcom: smd: Reset rx tail rather than tx

2016-09-01T19:19:50+00:00

The local end of each SMD channel is responsible for updating the tx head and the rx tail, as such we should not touch the tx tail during a reset. Reported-by: Jeremy McNicoll Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: smd: Represent smd edges as devices

2016-08-23T20:46:33+00:00

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 Signed-off-by: Andy Gross

soc: qcom: smd: Request irqs after parsing properties

2016-08-23T20:46:33+00:00

The code exectued by the interrupt handler depends on the values parsed after requesting the irq, just to be save we should therefor move the request_irq() call to be done after parsing the properties. Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: smd: Simplify multi channel handling

2016-08-23T20:46:32+00:00

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.

soc: qcom: smem: Silence probe defer error

2016-08-23T20:46:32+00:00

If we fail to get the hwspinlock due to probe defer, we shouldn't print an error message. Just be silent in this case. Cc: Bjorn Andersson Signed-off-by: Stephen Boyd Reviewed-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: Update properties for smem state referencing

2016-06-25T03:53:41+00:00

Update the property names to match device tree bindings, the correct values should be qcom,smem-states and qcom,smem-state-names. Also update the #qcom,smem-state-cells for consistency, before we merge any users of these properties. Signed-off-by: Bjorn Andersson Acked-by: Rob Herring Signed-off-by: Andy Gross

SMEM is now mapped write-combine and we can use memcpy to access the name of the entires. Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

soc: qcom: smp2p: Correct addressing of outgoing value

2016-06-24T18:34:00+00:00

The valid_entries index should not be incremented until after we have acquired the pointer to the value, or we will read and write data one item off.
