90caaef6a1 ALSA: hdsp: improve firmware caching
As the recent firmware code tries to reread and cache the firmware by
itself, it's even better to keep the struct firmware data instead of
keeping a local copy.  Also, it makes little sense to disable the fw
loader for this driver, so added the explicit dependency, too.

Last, but not least, allocate the firmware data loaded via ioctl in
vmalloc'ed buffer instead, as the firmware size isn't that small.

d1a3c98d50 ALSA: hdspm - Fix sync check reporting on RME RayDAT
The RayDAT reports the sync status of its inputs in consecutive bit
positions, so all we do in hdspm_s1_sync_check is to iterate over idx:

    status = hdspm_read(hdspm, HDSPM_RD_STATUS_1);

    lock = (status & (0x1<<idx)) ? 1 : 0;
    sync = (status & (0x100<<idx)) ? 1 : 0;

The index is given in kcontrol->private_value:

    HDSPM_SYNC_CHECK("WC SyncCheck", 0),
    HDSPM_SYNC_CHECK("AES SyncCheck", 1),
    HDSPM_SYNC_CHECK("SPDIF SyncCheck", 2),
    HDSPM_SYNC_CHECK("ADAT1 SyncCheck", 3),
    HDSPM_SYNC_CHECK("ADAT2 SyncCheck", 4),
    HDSPM_SYNC_CHECK("ADAT3 SyncCheck", 5),
    HDSPM_SYNC_CHECK("ADAT4 SyncCheck", 6),
    HDSPM_SYNC_CHECK("TCO SyncCheck", 7),
    HDSPM_SYNC_CHECK("SYNC IN SyncCheck", 8),

The patch corrects the indicated sync flags by passing the proper index
value to hdspm_s1_sync_check().

41285a98f8 ALSA: hdspm - Allow DDS/Varispeed to be set from userspace
The DDS value is the actual physical sample rate. We set it indirectly
when selecting 44100, 48000 and so on via snd_hdspm_hw_params or
hdspm_set_clock_source.

This commit now allows the DDS value to be altered at runtime, thus
speeding up or slowing down the physical sample rate. This is required
for MADI's varispeed that allows for ±12.5% speed adjustment from the
"selected" rate (32kHz, 44100kHz, 48kHz and so on).

f7de8ba3fc ALSA: hdspm - Provide unique driver id based on card serial
Before, /proc/asound looked like this:

 2 [Default        ]: HDSPM - RME RayDAT_f1cd85
                      RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18

In case of a second HDSPM card, its name would be Default_1. This is
cumbersome, because the order of the cards isn't stable across reboots.

To help userspace tools referring to the correct card, this commit
provides a unique id for each card:

 2 [HDSPMxf1cd85   ]: HDSPM - RME RayDAT_f1cd85
                      RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18

In this example, userspace (configuration files) would then use
hw:HDSPMxf1cd85 to choose the right card.

The serial is masked to 24bits, so this string is always shorter than
sixteen chars.

c09403dcc5 ALSA: hdspm - Enable all firmware ranges for PCI MADI/AES cards
From the Windows INF file, we know the firmware ranges for all RME
cards. For PCIe, a single revision ID per device (RayDAT, MADI, AIO,
AES) is used. Contrary, the older PCI versions use ranges, that is,
one revision ID per firmware version.

Instead of listing all possible revisions individually, match the range.

This commit enables all MADI and AES PCI versions ever shipped.

On newer RME cards like RayDAT and AIO, the 8192 samples per period size
are no longer supported. Instead, setting all three bits of

To make this more obvious to future developers, let's reorder the array
according to their bit representation, starting at 64 ({0,0,0}) up to
4096 ({1,1,0}) and finally 32 ({1,1,1}).

d12c51d829 ALSA: hdspm - Fix reported external sample rate on RME MADI and MADIface
In slave mode, the card can only detect the base frequency (32..48kHz)
on the MADI link (exception: 96k frames), so the real external sample
rate is this base frequency multiplied by 1, 2 or 4 depending on the
speed mode.

This patch enables 64..192kHz sample rates in clock slave mode, which
failed before due to an alleged sample rate mismatch between the MADI
link (e.g., 48kHz) and the application in DS/QS mode (e.g., 96kHz,
192kHz).

700d1ef33f ALSA: hdspm - Provide MADI speed mode selector on RME MADI and MADIface
When running in slave mode (no clock master), there is no way to
determine the real wirespeed on the MADI link (single/double/quad
speed). Like physical gear, simply provide the user with a tristate
switch to select the appropriate format.

The char can be unsigned on some architectures.  Since the code checks
the negative values, they should be declared as signed char explicitly.

The PCI version of the RME HDSP MADI card uses 0xcf as revision ID. Just
add this to the list of supported cards.

fedf1535ab ALSA: hdspm - Fix jumping external wordclock frequency in AutoSync mode
When using Word Clock on RME MADI cards, AutoSync mode was alternating
betweeen MADI and WC due to a typo: AutoSync is indicated in the second
status register (status2), not the first one (status).

While the proc output was always correct, the reported WC frequency to
ALSA was unstable as mentioned in

access to the global hdspm structure is serialized through
hmidi->hdspm->lock instead.

934c2b6d0c ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/*
The name argument of request_irq() appears in /proc/interrupts, and
it's quite ugly when the name entry contains a space or special letters.
In general, it's simpler and more readable when the module name appears
there, so let's replace all entries with KBUILD_MODNAME.
