2015-01-28ASoC: dwc: Remove unnecessary conditional compilationAndrew Jackson1-2/+0
of_match_ptr is already conditionally compiled based on CONFIG_OF so further conditional compilation is not required. Remove conditional compilation surrounding of_match_ptr. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-30ASoC: dwc: Add devicetree support for Designware I2SAndrew Jackson2-43/+151
Allow the driver to be configured through a device tree rather than platform data. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-30ASoC: dwc: Register components with managed interfaceAndrew Jackson1-2/+1
Register SOC component using managed interface to simplify error handling and future introduction of device tree. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-30ASoC: dwc: Prepare clock before useAndrew Jackson1-2/+5
Some I2S clocks may require some time to get the clock ready for operation and so need to be prepared before they are enabled. So, prepare the clock as well as enabling it, but combine the two through clk_prepare_enable. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-30ASoC: dwc: Read I2S block configuration from registersAndrew Jackson1-10/+86
The I2S block provides component parameter registers which describe how the block is instantiated. Use these registers to extract the block's configuration rather than relying on platform data. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-30ASoC: dwc: Switch to managed clock resourceAndrew Jackson1-8/+2
Simplify error handling during probe by using managed clock resources. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-22ASoC: dwc: Iterate over all channelsAndrew Jackson1-19/+16
The Designware core can be configured with up to four stereo channels. Each stereo channel is individually configured so, when the driver's hw_params call is made, each requested stereo channel has to be programmed. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-22ASoC: dwc: Ensure FIFOs are flushed to prevent channel swapAndrew Jackson1-0/+14
Flush the FIFOs when the stream is prepared for use. This avoids an inadvertent swapping of the left/right channels if the FIFOs are not empty at startup. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
2014-12-22ASoC: dwc: Reorder code in preparation for DT supportAndrew Jackson1-34/+39
Move code that configures the DAI and DMA into a separate function. This reduces the size of the dw_i2s_probe function and will make it easier to add support for device tree to the driver. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-22ASoC: dwc: Remove unnecessary debug messages and testsAndrew Jackson1-11/+2
The devm_XXX allocation functions print a message on failure, so additional messages are not required. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-12-14Merge tag 'driver-core-3.19-rc1' of ↵Linus Torvalds1-1/+0
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes. Everything has been in linux-next for a while" * tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (324 commits) Revert "ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries" fs: debugfs: add forward declaration for struct device type firmware class: Deletion of an unnecessary check before the function call "vunmap" firmware loader: fix hung task warning dump devcoredump: provide a one-way disable function device: Add dev_<level>_once variants ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries ath: use seq_file api for ath9k debugfs files debugfs: add helper function to create device related seq_file drivers/base: cacheinfo: remove noisy error boot message Revert "core: platform: add warning if driver has no owner" drivers: base: support cpu cache information interface to userspace via sysfs drivers: base: add cpu_device_create to support per-cpu devices topology: replace custom attribute macros with standard DEVICE_ATTR* cpumask: factor out show_cpumap into separate helper function driver core: Fix unbalanced device reference in drivers_probe driver core: fix race with userland in device_add() sysfs/kernfs: make read requests on pre-alloc files use the buffer. sysfs/kernfs: allow attributes to request write buffer be pre-allocated. fs: sysfs: return EGBIG on write if offset is larger than file size ...
2014-12-03ASoC: dwc: Allocate resources with devm_ioremap_resourceAndrew Jackson1-27/+19
Prepare for the introduction of device-tree support by re-ordering some of the allocations and using devm_iomap_resource to simplify IO mapping. Signed-off-by: Andrew Jackson <Andrew.Jackson@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-10-20ASoC: dwc: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2013-08-29ASoC: designware_i2s: Remove unnecessary dev_set_drvdata()Fabio Estevam1-4/+1

2013-01-26ASoC: dwc: fix support for more than two channelsDan Carpenter1-0/+4
There were missing break statements so everything used TWO_CHANNEL_SUPPORT. Also I added a return statement to silence a GCC warning: sound/soc/dwc/designware_i2s.c: In function ‘dw_i2s_hw_params’: sound/soc/dwc/designware_i2s.c:236:32: warning: ‘ch_reg’ may be used uninitialized in this function [-Wmaybe-uninitialized] Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Rajeev Kumar <rajeev-dlh.kumar@st.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-06-25ASoC: dwc: Bodge around continuing absence of clock API stubsMark Brown1-0/+1
The patches for stubbing out the generic clock API still haven't been applied so we need to either add ifdefs here or add a dependency until someone decides to actually apply them. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
