2018-12-16ALSA: fireface: allocate isochronous resources in mode-specific implementationTakashi Sakamoto
The way to maintain isochronous resources on bus is different between Fireface 400/800. This commit is a preparation. This commit moves a function to allocate resource to model-dependent implementation. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-12-16ALSA: fireface: code refactoring to handle multiplier modeTakashi Sakamoto
Fireface 400/800 use three modes against the number of data channels in data block for both tx/rx packets. This commit adds refactoring for it. Some enumerators are added to represent each of mode and a function is added to calculate the mode from sampling frequency code (sfc).

2018-12-16ALSA: fireface: share helper function to switch fetching modeTakashi Sakamoto
Both of Fireface 400/800 have the same register to switch frame fetching mode regardless of difference of available number of PCM frames in rx isochronous packet. This commit moves a helper function from model-dependent implementation. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-12-16ALSA: fireface: fix for state to fetch PCM framesTakashi Sakamoto
According to my memo at hand and saved records, writing 0x00000001 to SND_FF_REG_FETCH_PCM_FRAMES disables fetching PCM frames in corresponding channel, however current implement uses reversed logic. This results in muted volume in device side during playback. This commit corrects the bug.

2018-12-16ALSA: firewire-lib: use the same print format for 'without_header' tracepointsTakashi Sakamoto
An initial commit to add tracepoints for packets without CIP headers uses different print formats for added tracepoints. However this is not convenient for users/developers to prepare debug tools. This commit uses the same format for the two tracepoints.

2018-12-16ALSA: firewire-lib: fix wrong handling payload_length as payload_quadletTakashi Sakamoto
In IEC 61883-1/6 engine of ALSA firewire stack, a packet handler has a second argument for 'the number of bytes in payload of isochronous packet'. However, an incoming packet handler without CIP header uses the value as 'the number of quadlets in the payload'. This brings userspace applications to receive the number of PCM frames as four times against real time. This commit fixes the bug.

2018-12-14ASoC: Intel: Skylake: Add more platform granularityPierre-Louis Bossart
The current SKYLAKE kconfig is a all-you-can-eat selection that will support all known plaforms. This is however not necessarily a good thing: most platforms for SKL and KBL don't support the DSP, but a number of CNL/WHL ones do. Selecting this driver in all cases isn't really smart and will require users to muck with blacklists. Partition the configs to allow distributions to select on which platform this driver is used. Keep the existing SND_SOC_INTEL_SKYLAKE config to select everything for backwards compatibility. This patch does not provide new functionality, only finer-grained choices in supported platforms.

2018-12-11ALSA: fireface: add support for Fireface 800 with MIDI functionality onlyTakashi Sakamoto
Fireface 800 is a flagship model of RME GmbH for audio and music units on IEEE 1394 bus, shipped 2004. This model consists of four chips: - TI TSB81BA3D for physical layer on cable environment of EEE 1394 bus - TI TSB82AA2 for link layer for 1394 OHCI bus bridge to PCI bus - Xilinx Spartan-3 FPGA XC3S400 - Xilinx High-Performance CPLD XC9572XL This commit adds support Fireface 800. In this time, the support is restricted to its MIDI functionality, thus this commit adds some condition statements to avoid touching streaming functionality. Unlike Fireface 400, Fireface 800 has no functionality to suppress asynchronous transactions for MIDI messages except for unregister of listen address in controller side, thus the feature is available as is.

2018-12-11ALSA: fireface: localize a handler for MIDI messages on tx transactionTakashi Sakamoto
Content of asynchronous transaction for MIDI messages differs between Fireface 400 and 800. This commit adds a model-specific handler for the transaction and adds arrangement. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-12-11ALSA: fireface: add driver data for register for MIDI high addressTakashi Sakamoto
Fireface 400 and 800 have the same mechanism to decide address to which asynchronous transactions are sent for MIDI messages, however they use different registers for controllers to notify higher 4 byte of the address. This commit adds a model-specific parameter to represent the address. Additionally, it corrects some comments. I note that these two models have a difference to enable/disable the transaction.
