* dmaengine: pl330: Embed pl330_req directly into dma_pl330_descLars-Peter Clausen2014-07-151-90/+69
| | | | | | | | | | | The pl330_req struct is embedded into the dma_pl330_desc struct. But half of the pl330_req struct are pointers to other fields of the dma_pl330_desc struct it is embedded to. By directly embedding the fields from the pl330_req struct into the dma_pl330_desc struct and reworking the code to work with the dma_pl330_desc struct those pointers can be eliminated. This slightly simplifies the code. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
* dmaengine: pl330: Merge dma_pl330_dmac and pl330_dmac structsLars-Peter Clausen2014-07-151-280/+192
| | | | | | | | | | | | | | Both the dma_pl330_dmac and the pl330_dmac struct have the same lifetime and the separation of them is a relict of this having been two different drivers in the past. Merging them into one struct makes the code a bit simpler as it for example allows to remove the pointers going back and forth between the two structs. While we are at it also directly embed the pl330_info struct into the pl330_dmac struct as this allows to remove some more redundant fields.

* dmaengine: pl330: Change type pl330_chid from void * to struct pl330_thread *Lars-Peter Clausen2014-07-151-20/+17
| | | | | | | | | | | The pl330_chid field of the dma_pl330_chan struct always holds a pointer to the thread that is associated with the channel. Changing its type form void * to struct pl330_thread makes things more type safe and removes the need for unnecessary typecasts. While we are at it also rename the field from the cryptic pl330_chid to thread. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

| | | | | | | | | | The pl330 driver has the custom pl330_reqtype enum which has the same possible settings as the generic dma_transfer_direction enum.

* dmaengine: qcom_bam_dma: Add descriptor flagsAndy Gross2014-07-141-2/+18
| | | | | | | | | | | | | | | | | This patch adds support for end of transaction (EOT) and notify when done (NWD) hardware descriptor flags. The EOT flag requests that the peripheral assert an end of transaction interrupt when that descriptor is complete. It also results in special signaling protocol that is used between the attached peripheral and the core using the DMA controller. Clients will specify DMA_PREP_INTERRUPT to enable this flag. The NWD flag requests that the peripheral wait until the data has been fully processed by the peripheral before moving on to the next descriptor. Clients will specify DMA_PREP_FENCE to enable this flag. Signed-off-by: Andy Gross <agross@codeaurora.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
* dmaengine: Freescale: change descriptor release process for supporting async_txHongbo Zhang2014-07-142-55/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the potential risk when enable config NET_DMA and ASYNC_TX. Async_tx is lack of support in current release process of dma descriptor, all descriptors will be released whatever is acked or no-acked by async_tx, so there is a potential race condition when dma engine is uesd by others clients (e.g. when enable NET_DMA to offload TCP). In our case, a race condition which is raised when use both of talitos and dmaengine to offload xor is because napi scheduler will sync all pending requests in dma channels, it affects the process of raid operations due to ack_tx is not checked in fsl dma. The no-acked descriptor is freed which is submitted just now, as a dependent tx, this freed descriptor trigger BUG_ON(async_tx_test_ack(depend_tx)) in async_tx_submit().

Hardware should not be depend on s/w list, the right way is to read current descriptor address register to find the last completed descriptor. If an interrupt is raised by an error, all descriptors in ld_running should not be seemed finished, or these unfinished descriptors in ld_running will be released wrongly. A simple way to reproduce: Enable dmatest first, then insert some bad descriptors which can trigger Programming Error interrupts before the good descriptors. Last, the good descriptors will be freed before they are processsed because of the exception intrerrupt. Note: the bad descriptors are only for simulating an exception interrupt. This case can illustrate the potential risk in current fsl-dma very well.

* dmaengine: Freescale: use spin_lock_bh instead of spin_lock_irqsaveHongbo Zhang2014-07-141-15/+10
| | | | | | | | | | | | | | | The usage of spin_lock_irqsave() is a stronger locking mechanism than is required throughout the driver. The minimum locking required should be used instead. Interrupts will be turned off and context will be saved, it is unnecessary to use irqsave. This patch changes all instances of spin_lock_irqsave() to spin_lock_bh(). All manipulation of protected fields is done using tasklet context or weaker, which makes spin_lock_bh() the correct choice.

This pull request contains fixes for various issues found while testing -rc versions of Linux 3.16. Mostly two kinds of patches: * Fixes of incorrectly defined clocks 1) a37c82a clk: samsung: exynos4: Remove SRC_MASK_ISP gates Issue present since v3.10. 2) 0b1643b clk/exynos5250: fix bit number for tv sysmmu clock Issue present since v3.16. 3) 44ff025 clk: exynos5420: Remove aclk66_peric from the clock tree description Issue present since v3.11. * Adding things missed by original patches 1) cec1cde clk: samsung: fix several typos to fix boot on s3c2410 2) 34ece9e clk: samsung: add more aliases for s3c24xx Both issues present since the driver was added in v3.16. 3) a92dda4 clk: s3c64xx: Hookup SPI clocks correctly Issue present since v3.12.

This big gate isn't very useful to include in our clock tree. If any of the children need to be turned on then the big gate will need to be on anyway. ...and there are plenty of other "big gates" that aren't described in our clock tree, some of which shut off collections of clocks that have no relationship in the hierarchy so are hard to model. "aclk66_peric" is causing earlyprintk problems since it gets disabled as part of the boot process, so let's just remove it. Strangely (and for no good reason) this clock is exported as part of the common clock bindings. Remove it since there are no in-kernel device trees using it and no reason anyone out of tree should refer to it either.

This patch adds them back in. When taking the clock from the epll clock (SCLK) the rates on the SPI bus are incorrect, this needs further debugging but the hookup here should be correct and the problem should be else where. The USBCLK case has been dropped because this requires the USB PHY to be enabled. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Tomasz Figa <t.figa@samsung.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ISP special clocks have dedicated gating registers and so MUX SRC_MASK register should not be used. This patch fixes the problem of Exynos4x12-based boards freezing on system suspend, because those mux outputs need not to be masked while suspending.

This is a rather dangerous default, and causes problems on AM43x when using display and ethernet. There are multiple ways to select the clock muxes on AM43x, and some of those clock paths have the same source clocks for display and ethernet. When changing the clock rate for the display subsystem, the clock framework decides to change the display mux from the dedicated display PLL to a shared PLL which is used by the ethernet, and then changes the rate of the shared PLL, breaking the ethernet. As I don't think there ever is a case where we want the clock framework to automatically change the parent clock of a clock mux, this patch sets the CLK_SET_RATE_NO_REPARENT for all ti,mux-clocks.
