2009-10-01ALSA: Don't assume i2c device probing always succeedsTakashi Iwai1-0/+9
The client->driver pointer can be NULL when i2c-device probing fails in i2c_new_device(). This patch adds the NULL checks for client->driver and return the error instead of blind assumption of driver availability.

2009-05-12sound: remove driver_data direct access of struct deviceGreg Kroah-Hartman2-8/+8
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

2009-01-15ALSA: snd-aoa: handle master-amp if presentJohannes Berg3-1/+25
Some machines have a master amp GPIO that needs to be toggled to get sound output, in addition to speaker/headphone/line-out amps. This makes snd-aoa handle it, if present in the device tree, thus making snd-aoa be able to output sound on PowerMac3,6, which was previously handled by snd-powermac which also doesn't use the master amp GPIO.

2009-01-15ALSA: snd-aoa: handle older machinesJohannes Berg2-22/+74
This patch changes snd-aoa to handle some older machines that are currently handled by snd-powermac. snd-aoa has a number of advantages though, notably it can autoload better and is generally a more modern driver. By hardcoding the accepted device-ids (last hunk of the patch) I'm trying to avoid regressions because this driver will otherwise load automatically and not let snd-powermac load. People who are unhappy with snd-powermac and have a device-id property in the device tree are encouraged to read this patch and make a patch to amend this as appropriate.

2007-02-09[ALSA] aoa i2sbus: Stop Apple i2s DMA gracefullyPaul Mackerras3-146/+210
This fixes the problem of getting extra bytes inserted at the beginning of a recording when using the Apple i2s interface and DBDMA controller. It turns out that we can't just abort the DMA; we have to let it stop at the end of a command, and then wait for the S7 bit to be set before turning off the DBDMA controller. Doing that for playback doesn't seem to be necessary, but doesn't hurt either. We use the technique used by the Darwin driver: make each transfer command branch to a stop command if the S0 status bit is set. Thus we can ask the DMA controller to stop at the end of the current command by setting S0. The interrupt routine now looks at and clears the status word of the DBDMA command ring. This is necessary so it can know when the DBDMA controller has seen that S0 is set, and so when it should look for the DBDMA controller being stopped and S7 being set. This also ended up simplifying the calculation in i2sbus_pcm_pointer. Tested on a 15 inch albook. [Addition by Johannes] I modified this patch and added the suspend/resume bits to it to get my powermac into a decent state when playing sound across suspend to disk that has a different bitrate from what the firmware programs the hardware to. I also added the SNDRV_PCM_INFO_JOINT_DUPLEX flag because it seemed the right thing to do and I was looking at the info stuff.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells4-10/+7
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
