* video i.MX IPU: Fix display connectionsSascha Hauer2011-12-08
| | | | | | | | | | | | | | | | | | | The IPU internally works on 32bit colors. It can arbitrarily map between pixel formats and internal representation and also between internal representation and the physical connection to the display. The driver used to change the mapping between internal representation and display connection depending on the user selected bpp which is wrong. Instead, the mapping is specified by the hardware, so an additional field in platform data is added to describe the connection between i.MX and the display. The default for this field is RGB666 which seems to be the only configuration which works without this patch, so I assumed that all in Kernel boards are connected this way. This patch has been tested on a RGB666 connected display and a RGB888 connected display in both 16bpp and 32bpp modes.

* i.MX IPU DMA: Fix wrong burstsize settingsSascha Hauer2011-12-08
| | | | | | | | | | | | | | | | | The burstsize (npb in struct chan_param_mem) is set in ipu_ch_param_set_size() once. The number of allowed pixels in a burst depend on the pixel format and the rotation mode. For 16bit formats 16 pixels are allowed whereas for 32bit formats only 8 pixels are allowed. Set these values correctly in ipu_ch_param_set_size() and do not overwrite them afterwards. We do not support rotation right now, so ignore this case. This patch fixes the wrong burstsize setting of 16 pixels for 32bpp. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
* dmaengine/ste_dma40: allow fixed physical channelNarayanan G2011-12-04
| | | | | | | | | | | | Allow logical channels to specify the physical channel they want to use. This is needed to avoid two peripherals operating on the same physical channel during some special use-cases. (like mmc and usb during a usb mass storage case).

| | | | | | | | | | | Currently, if plchan->phychan is true, we return immediately from prep_phy_chan(). We must configure txd->ccfg and increment phychan_hold before returning. Otherwise, request line number wouldn't be configured in this txd.

* IMX/SDMA : save the real count for one DMA transaction.Huang Shijie2011-12-04
| | | | | | | | | | | | | | | | | When we use the SDMA in the UART driver(such as imx6q), we will meet one situation: Assume we set 64 bytes for the RX DMA buffer. The RX DMA buffer has received some data, but not full. An Aging DMA request will be received by the SDMA controller if we enable the IDDMAEN(UCR4[6]) in this case. So the UART driver needs to know the count of the real received bytes, and push them to upper layer. Add two new fields to sdmac, and update the `residue` in sdma_tx_status().

* dmaengine/dw_dmac: Reconfigure interrupt and chan_cfg register on resumeViresh Kumar2011-11-27
| | | | | | | | | | | | | | | | | In S2R all DMA registers are reset by hardware and thus they are required to be reprogrammed. The channels which aren't reprogrammed are channel configuration and interrupt enable registers, which are currently programmed at chan_alloc time. This patch creates another routine to initialize a channel. It will try to initialize channel on every dwc_dostart() call. If channel is already initialised then it simply returns, otherwise it configures registers. This routine will also initialize registers on wakeup from S2R, as we mark channels as uninitialized on suspend.

* DMAEngine: Define interleaved transfer request apiJassi Brar2011-11-18
| | | | | | | | | | | | | | | | | | | | | | Define a new api that could be used for doing fancy data transfers like interleaved to contiguous copy and vice-versa. Traditional SG_list based transfers tend to be very inefficient in such cases as where the interleave and chunk are only a few bytes, which call for a very condensed api to convey pattern of the transfer. This api supports all 4 variants of scatter-gather and contiguous transfer. Of course, neither can this api help transfers that don't lend to DMA by nature, i.e, scattered tiny read/writes with no periodic pattern. Also since now we support SLAVE channels that might not provide device_prep_slave_sg callback but device_prep_interleaved_dma, remove the BUG_ON check.

| | | | | | | | | | | | | | | | | | | | | | We remove the use of platform data from DMA controller driver. We now use of .id_table to distinguish between compatible types. The two implementations allow to determine the number of channels and the capabilities of the controller.
