Variax driver had a very complex and staged startup sequence using multiple timers and a work. This patch simplifies the procedure to a single delayed work. Now the startup stage consists of: - VARIAX_STARTUP_VERSIONREQ: requesting the version and the message handler raises up to the next stage upon receiving the reply. The request is repeated until a reply arrives. - VARIAX_STARTUP_ACTIVATE: does activation, and queue for the next stage. - VARIAX_STARTUP_SETUP: registers the card. Signed-off-by: -

The POD driver had a complex staged startup procedure using both timer and work. This patch simplifies it via a single delayed work with the reduced stages. Now basically only two intermediate stages: - POD_STARTUP_VERSIONREQ: requesting the version information and the process_message callback triggers the next stage, - POD_STARTUP_SETUP: registering the actual card object.

The current code performs the cancel of a delayed work at the late stage of disconnection procedure, which may lead to the access to the already cleared state. This patch assures to call cancel_delayed_work_sync() at the beginning of the disconnection procedure for avoiding that race. The delayed work object is now assigned in the common line6 object instead of its derivative, so that we can call cancel_delayed_work_sync(). Along with the change, the startup function is called via the new callback instead. This will make it easier to port other LINE6 drivers to use the delayed work for startup in later patches.

In Linux firewire subsystem, for IT context, some quadlets of isochronous packet payload can be indicated as a part of packet header to queue to the context. This commit uses the packet header to split CIP headers from CIP payload. As a result, regardless of CIP or non-CIP, context payload includes data blocks only. Signed-off-by:

By taking into account the mapping from logical to DMA channels when enabling or disabling audio channels, ADAT channels 3 to 8 on the RME HDSPe AIO card are now correctly captured and played back in single speed mode. Since the mapping is an identity mapping for all cards except AIO and RayDAT, only those cards should be affected by this patch. It was tested on an AIO card. The patch needs testing on other cards, in particular RayDAT. Note: this patch does not solve ADAT capture and playback issues in double or triple speed mode. That seems to be another problem.

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(struct rate_priv) + src_format->channels * sizeof(struct rate_channel) with: struct_size(data, channels, src_format->channels) This code was detected with the help of Coccinelle.

In IR context, some quadlets of packet payload can be included into context header. This is good for packet with CIP header because the context payload buffer can includes data blocks only for with-CIP and without-CIP pakets. This commit uses 16 bytes IR context header for this purpose. Signed-off-by:

In current packet handler, the length of payload is given as an argument of callback function, however this value is just required to process payload of transferred isoc packet, thus just for IR context. This commit replaces the argument for payload of packet with the argument of context header. As a result, the length of payload is computed in packet handler for IR context. Signed-off-by:

I measured power consumption between power_save_node=1 and power_save_node=0. It's almost the same. Codec will enter to runtime suspend and suspend. That pin also will enter to D3. Don't need to enter to D3 by single pin. So, Disable power_save_node as default. It will avoid more issues. Windows Driver also has not this option at runtime PM. Signed-off-by:

In IT context, header includes information of cycle to have processed queued packet. This commit uses the per-packet information to compute the cycle for packet to be queued, instead of callback argument. In current implementaion of ALSA IEC 61883-1/6 packet streaming engine, 48 packets are queued at first to skip recent cycle. When IT context calls handler, cycle information in header plus 48 cycle means the cycle to be going to queue packet. Signed-off-by:
