ASoC: fix broken pxa SoC support

2015-10-13T02:46:10+00:00

commit 3c8f7710c1c44fb650bc29b6ef78ed8b60cfaa28 upstream. The previous fix of pxa library support, which was introduced to fix the library dependency, broke the previous SoC behavior, where a machine code binding pxa2xx-ac97 with a coded relied on : - sound/soc/pxa/pxa2xx-ac97.c - sound/soc/codecs/XXX.c For example, the mioa701_wm9713.c machine code is currently broken. The "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared in sound/arm/Kconfig and sound/soc/pxa/Kconfig. Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct pxa2xx-ac97 compilation.

ALSA: pxa27x: fix ac97 warm reset

2013-02-06T04:33:26+00:00

commit 3b4bc7bccc7857274705b05cf81a0c72cfd0b0dd upstream. This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me.

ALSA: pxa27x: fix ac97 cold reset

2013-02-06T04:33:26+00:00

commit 41b645c8624df6ace020a8863ad1449d69140f7d upstream. Cold reset on the pxa27x currently fails and pxa2xx_ac97_try_cold_reset: cold reset timeout (GSR=0x44) appears in the kernel log. Through trial-and-error (the pxa270 developer's manual is mostly incoherent on the topic of ac97 reset), I got cold reset to complete by setting the WARM_RST bit in the GCR register (and later noticed that pxa3xx does this for cold reset as well). Also, a timeout loop is needed to wait for the reset to complete. Tested on a palm treo 680 machine.

sound: Add module.h to the previously silent sound users

2011-10-31T23:31:21+00:00

Lots of sound drivers were getting module.h via the implicit presence of it in but we are going to clean that up. So fix up those users now. Signed-off-by: Paul Gortmaker

sound: irq: Remove IRQF_DISABLED

2011-09-22T09:19:20+00:00

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by: Yong Zhang Acked-by: Peter Ujfalusi Acked-by: Mark Brown Signed-off-by: Takashi Iwai

ASoC: PXA: Fix oops in __pxa2xx_pcm_prepare

2011-04-03T09:48:56+00:00

pxa2xx_pcm_hw_free frees dma channel and sets prtd->dma_ch to -1, but does not set prtd->params to NULL, so if pxa2xx_pcm_hw_params will be called immediately, it leaves prtd->dma_ch initialized with -1, and it results in oops in __pxa2xx_pcm_prepare. This bug is triggered via SDL. This patch adds check for prtd->dma_ch to __pxa2xx_pcm_prepare and cleans prtd->params, so now it works properly.
