* ASoC: kirkwood: Fix module autoload for OF platform driverLuis de Bethencourt2015-09-141-0/+1
| | | | | | | | This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt <luis@debethencourt.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: kirkwood: prevent double streamingJean-Francois Moine2015-07-211-0/+4
| | | | | | | | | | The kirkwood audio subsystem presents 2 PCM's for one source. Streaming on a second PCM while the first one is active cuts this last one. Then, ending the last stream gives a kernel trap in free_irq(). Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mark Brown <broonie@kernel.org>

* / ASoC: kirkwood: fix struct clk pointer comparingShawn Guo2015-03-121-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | Since commit 035a61c314eb ("clk: Make clk API return per-user struct clk instances"), clk API users can no longer check if two struct clk pointers are pointing to the same hardware clock, i.e. struct clk_hw, by simply comparing two pointers. That's because with the per-user clk change, a brand new struct clk is created whenever clients try to look up the clock by calling clk_get() or sister functions like clk_get_sys() and of_clk_get(). This changes the original behavior where the struct clk is only created for once when clock driver registers the clock to CCF in the first place. The net change here is before commit 035a61c314eb the struct clk pointer is unique for given hardware clock, while after the commit the pointers returned by clk lookup calls become different for the same hardware clock. That said, the struct clk pointer comparing in the code doesn't work any more. Call helper function clk_is_match() instead to fix the problem.

Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...
| * DMA-API: sound: fix dma mask handling in a lot of driversRussell King2013-10-311-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code sequence is unsafe in modules: static u64 mask = DMA_BIT_MASK(something); ... if (!dev->dma_mask) dev->dma_mask = &mask; as if a module is reloaded, the mask will be pointing at the original module's mask address, and this can lead to oopses. Moreover, they all follow this with: if (!dev->coherent_dma_mask) dev->coherent_dma_mask = mask; where 'mask' is the same value as the statically defined mask, and this bypasses the architecture's check on whether the DMA mask is possible. Fix these issues by using the new dma_coerce_coherent_and_mask() function.

* ASoC: kirkwood: change the compatible string of the kirkwood-i2s driverThomas Petazzoni2013-09-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The compatible string of the kirkwood-i2s driver was chosen as "marvell,mvebu-audio". Using such a compatible string is not a good idea, since "mvebu" is the name of a large family of SOCs, in which new, unknown SOCs will be coming in the future. It is therefore impossible to know what will be evolutions of this hardware block in the next generations of the SOCs. For this reason, the recommandation for compatible strings of on-SOCs devices has always been to use the name of the oldest SOC that has the hardware block. New SOCs that have an exactly compatible hardware block can reference it using the same compatible string. See [1], [2] and [3] for various cases were this suggestion was made, including from Rob Herring, a Device Tree binding maintainer. As an example, there are already small differences between current generations: * On Kirkwood, only one interrupt is used for audio. * On Dove, two interrupts are used, one for audio data and one for error reporting. In the near future, I'll be adding audio support to Armada 370, which allows has the same hardware block (but maybe with minor variants). Therefore, this patch changes the driver to accept "marvell,kirkwood-audio" and "marvell,dove-audio" as compatible strings instead of the too-generic "marvell,mvebu-audio". The reason for the two different compatible strings is the difference in the number of interrupts used by the two SOCs for audio. This Device Tree binding has never been part of a Linux kernel stable release so far, so it can be changed now without breaking backward compatibility.

* ASoC: kirkwood: merge struct kirkwood_dma_priv with struct kirkwood_dma_dataRussell King2013-08-052-54/+24
| | | | | | | | | | | | | | Merge these two structures together; nothing other than the I2S and DMA driver makes use of struct kirkwood_dma_data, and it's not like struct kirkwood_dma_data is really just used to convey DMA specific data to the backend; it's more a general shared structure between the two halves. This will later allow kirkwood-dma.c and kirkwood-i2s.c to be merged together. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: kirkwood-i2s: fix a compilation warningJean-Francois Moine2013-07-161-3/+5
| | | | | | | | | | | | | | | | | | | In the function kirkwood_set_rate, when the rate cannot be satisfied by the internal nor by an external clock, the clock source in undefined: warning: ‘clks_ctrl’ may be used uninitialized in this function The ALSA subsystem should never gives such a rate because: - the rates with the internal clock are limited to 44.1, 48 and 96 kHz as specified by the kirkwood_i2s_dai structure, - the other rates are proposed in the structure kirkwood_i2s_dai_extclk only when the external clock is present. In case of programming error (bad rate for internal clock and no external clock), the function will simply cause a backtrace.

* ASoC: kirkwood-i2s: Inline KIRKWOOD_I2S_RATESMark Brown2013-07-161-5/+4
| | | | | | | | The addition of extclk support makes this misleading as it's only the rates used when there is no extclk so put it in the specific DAI it applies to. Signed-off-by: Mark Brown <broonie@linaro.org>
