Instead of allocating/deallocating URBs and transfer buffers every time stream is started/stopped, just do it once. That reduces the memory allocation pressure and makes the code that start/stop streaming a way simpler. Signed-off-by:

Instead of allocating transfer buffers with kmalloc() use usb_alloc_coherent(). This patch should make it work also with ARM CPUs. Reviewed-by:

The comment incorrectly explains that the code verifies information provided by userspace, while verification has been performed earlier in reality. Fix it. Signed-off-by:

Current setting of symbol rate is not very actuate causing loss of lock. Covert temp to u64 and use mclk to calculate from big number. Calculate symbol rate by dividing symbol rate by 1000 times 1 << 24 and dividing sum by mclk. Add other symbol rate settings to function registers 0xa0-0xa3. In set_frontend add changes to register 0xf1 this must be done prior call to fe_reset. Register 0x00 doesn't need a second write of 0x1 Applied after patch m88rs2000: add m88rs2000_set_carrieroffset Signed-off-by:

Malcolm Priestley authored
Set the carrier offset correctly using the default mclk values. Add function m88rs2000_get_mclk to calculate the mclk value against crystal frequency which will later be used for other functions. Add function m88rs2000_set_carrieroffset to calculate and set the offset value. variable offset becomes a signed value. Register 0x86 is set the appropriate value according to remainder value of frequency % 192857 calculation as shown. Signed-off-by:

Set the return variable to an error code as done elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by:

The rest of the function uses ret to store the return value, even setting ret to i a few lines before this, so return ret instead of i. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by:

The audio configuration in chip config register 0x00 and eeprom are always consistent. But currently the audio configuration #defines for the chip config register say 0x20 means 3 sample rates and 0x30 5 sample rates, while the eeprom info output says 0x20 means 1 sample rate and 0x30 3 sample rates. I've checked the datasheet excerpts I have and it seems that the meaning of these bits is different for em2820/40 (1 and 3 sample rates) and em2860+ (3 and 5 smaple rates). I have also checked my Hauppauge WinTV USB 2 (em2840) and the chip/eeprom audio config 0x20 matches the sample rates reproted by the USB device descriptor (32k only). Signed-off-by:

Under abnormal conditions (such as glitches on the HSYNC/VSYNC signals) the CCDC output SBL can fail to become idle. The driver currently logs this condition to the kernel log and doesn't restart the CCDC. This results in CCDC video capture hanging without any notification to userspace. Cancel the pipeline and mark the CCDC as crashed instead of hanging. Userspace will be notified of the problem and will then be able to close and reopen the device to trigger a reset of the ISP.

Laurent Pinchart authored
When a fatal error that prevents any further video streaming occurs in a pipeline, all queued buffers must be marked as erroneous and new buffers must be prevented from being queued. Implement this behaviour with a new omap3isp_pipeline_cancel_stream() function that can be used by submodules to cancel streaming. Signed-off-by:
