soc: qcom: smem: Use le32_to_cpu for comparison

2020-04-24T05:59:10+00:00

[ Upstream commit a216000f0140f415cec96129f777b5234c9d142f ]

Endianness can vary in the system, add le32_to_cpu when comparing
partition sizes from smem.

gsbi->hclk is left undisabled.

soc: qcom: wcnss_ctrl: Fix increment in NV upload

2018-05-30T05:50:47+00:00

[ Upstream commit 90c29ed7627b6b4aeb603ee197650173c8434512 ]

hdr.len includes both the size of the header and the fragment, so using
this when stepping through the firmware causes us to skip 16 bytes every
chunk of 3072 bytes; causing only the first fragment to actually be
valid data.

Instead use fragment size steps through the firmware blob.

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.

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.

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.

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.

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.
