[alsa-devel] [PATCH v4 00/18] new MFD LoCoMo driver set
by Dmitry Eremin-Solenikov 02 Jun '15

02 Jun '15

Sharp Zaurus SL-5500 and SL-5600 use special companion Gate Array. With this patchset I tried to modernise and restructure the LoCoMo drivers. * Use platform bus and mfd core code * Use GPIO API instead of custom locomo GPIO code * Use irqdomains to manage IRQs * Split mixed locomolcd driver to lcd and backlight parts * Implement IRQ handling in GPIO driver * Implement SPI driver used as a host for mmc_spi device to control SD cards Changes since v3: * Removed magic values in locomo irq handling code * Using mutex in locomokbd driver * Dropped empty locomokbd_remove * Small rearrangement of headers/comments/etc in core and input drivers The following changes since commit b787f68c36d49bb1d9236f403813641efa74a031: Linux 4.1-rc1 (2015-04-26 17:59:10 -0700) are available in the git repository at: git://git.infradead.org/users/dbaryshkov/zaurus.git locomo-v4 for you to fetch changes up to 7c8e8e05ca27a4ad82356eb57ad12a7ca39bfd95: ARM: drop old LoCoMo driver (2015-05-25 14:29:23 +0300) ---------------------------------------------------------------- Dmitry Eremin-Solenikov (18): mfd: add new driver for Sharp LoCoMo leds: port locomo leds driver to new locomo core input: convert LoCoMo keyboard driver to use new locomo core input: locomokbd: differentiate between two Enter keys input: make LoCoMo keyboard driver support both poodle and collie video: backlight: add new locomo backlight driver video: lcd: add LoCoMo LCD driver gpio: port LoCoMo gpio support from old driver gpio: locomo: implement per-pin irq handling spi: add locomo SPI driver i2c: add locomo i2c driver ARM: sa1100: make collie use new locomo drivers ARM: sa1100: don't preallocate IRQ space for locomo ASoC: pxa: poodle: make use of new locomo GPIO interface ARM: pxa: poodle: use new LoCoMo driver ARM: pxa: poodle: don't preallocate IRQ space for locomo video: backlight: drop old locomo bl/lcd driver ARM: drop old LoCoMo driver arch/arm/common/Kconfig | 3 - arch/arm/common/Makefile | 1 - arch/arm/common/locomo.c | 914 ----------------------------- arch/arm/include/asm/hardware/locomo.h | 221 ------- arch/arm/mach-pxa/Kconfig | 1 - arch/arm/mach-pxa/include/mach/poodle.h | 8 +- arch/arm/mach-pxa/poodle.c | 58 +- arch/arm/mach-sa1100/Kconfig | 1 - arch/arm/mach-sa1100/collie.c | 213 +++++-- arch/arm/mach-sa1100/include/mach/collie.h | 16 +- arch/arm/mach-sa1100/include/mach/irqs.h | 19 +- drivers/gpio/Kconfig | 13 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-locomo.c | 285 +++++++++ drivers/i2c/busses/Kconfig | 12 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-locomo.c | 135 +++++ drivers/input/keyboard/Kconfig | 2 +- drivers/input/keyboard/locomokbd.c | 262 ++++----- drivers/leds/Kconfig | 2 +- drivers/leds/leds-locomo.c | 117 ++-- drivers/mfd/Kconfig | 10 + drivers/mfd/Makefile | 1 + drivers/mfd/locomo.c | 336 +++++++++++ drivers/spi/Kconfig | 10 + drivers/spi/Makefile | 1 + drivers/spi/spi-locomo.c | 332 +++++++++++ drivers/video/backlight/Kconfig | 16 +- drivers/video/backlight/Makefile | 3 +- drivers/video/backlight/locomo_bl.c | 153 +++++ drivers/video/backlight/locomo_lcd.c | 285 +++++++++ drivers/video/backlight/locomolcd.c | 255 -------- include/linux/mfd/locomo.h | 169 ++++++ sound/soc/pxa/poodle.c | 52 +- 34 files changed, 2205 insertions(+), 1703 deletions(-) delete mode 100644 arch/arm/common/locomo.c delete mode 100644 arch/arm/include/asm/hardware/locomo.h create mode 100644 drivers/gpio/gpio-locomo.c create mode 100644 drivers/i2c/busses/i2c-locomo.c create mode 100644 drivers/mfd/locomo.c create mode 100644 drivers/spi/spi-locomo.c create mode 100644 drivers/video/backlight/locomo_bl.c create mode 100644 drivers/video/backlight/locomo_lcd.c delete mode 100644 drivers/video/backlight/locomolcd.c create mode 100644 include/linux/mfd/locomo.h

[alsa-devel] [RFC][PATCH] x86: remove vmalloc.h from asm/io.h
by Stephen Rothwell 02 Jun '15

02 Jun '15

Nothing in asm/io.h uses anything from vmalloc.h, so remove the include and fix up the build problems in an allmodconfig (64 bit and 32 bit) build. This may be the place where x86 builds get vmalloc.h implicitly included and that tends to hide places where vmalloc() et al are added to files but the include of vmalloc.h is forgotten.

[alsa-devel] [PATCH 0/2] Update ALSA driver to use media controller API
by Shuah Khan 01 Jun '15

01 Jun '15

This patch series updates ALSA driver to use media controller API to share tuner with DVB and V4L2 drivers that control AU0828 media device. Two new interfaces are added to media controller API to enable creating media device as a device resource. This allows creating media device as a device resource on the main struct device that is common to all drivers that control a single media hardware and share resources on it. Drivers then can find the common media device to register entities and manage links, and pipelines. Tested with and without CONFIG_MEDIA_CONTROLLER enabled. Tested tuner entity doesn't exist case as au0828 v4l2 driver is the one that will create the tuner when it gets updated to use media controller API. Please note that au0828 updates media controller are necessary before the resource sharing can work across ALSA and au0828 dvb and v4l2 drivers. This work is in progress and another developer is working on it.

[alsa-devel] Audio play problem with tlv320aic3106 in mainline.
by Enric Balletbo Serra 01 Jun '15

01 Jun '15

Dear all, Recently I sent some patches to add support for a new board based on AM335x processor [1]. The board has the TLV320AIC3106 audio codec, the MCLK signal is provided by an external oscillator of 12MHz. The problem is that when I play a wav file for example I heard the song a double speed. This is with v4.0 and current mainline. In dts file I defined "ti,codec-clock-rate = <12000000>;" which is the correct value. Curiously when I changed the clock rate value to 24000000 I heard the song at normal speed. AFAIK the correct value for clock-rate is 12MHz so I suspect that something is wrong in the driver, maybe it sets a wrong clock divider/multiplier ? Anyone can point me in the right direction to fix the issue ? I see that am335x-evm and am335x-pepper boards also uses this audio codec, did anyone with those boards have the same problem?

[alsa-devel] [RFC] sound: ppc: keywest: check if DEQ was already instantiated
by Wolfram Sang 01 Jun '15

01 Jun '15

Due to changes in i2c-powermac, for some Macs the DEQ is instantiated now in i2c-powermac while some need the instantiation here in the keywest sound driver. The proper fix is to convert this driver to AOA. Until then support both ways of instantiation. Before this patch, some Macs lost sound because the sound driver failed when instantiating the DEQ for the second time. Signed-off-by: Wolfram Sang <wsa(a)the-dreams.de> --- Dan, Mark: I hope I found a generic but not too intrusive solution to the doubled instantiation problem.

[alsa-devel] [PATCH] ALSA: usb-audio: don't try to get Outlaw RR2150 sample rate
by Eric Wong 30 May '15

30 May '15

This quirk allows us to avoid the noisy: current rate 0 is different from the runtime rate message every time playback starts. While USB DAC in the RR2150 supports reading the sample rate, it never returns a sample rate other than zero in my observation with common sample rates.
