[ Upstream commit d8fc21c17099635e8ebd986d042be65a6c6b5bd0 ] When devm_ioremap_resource() fails, isp should be freed just like other error paths in isp_probe.

media: omap3isp: remove cacheflush.h

2020-06-26T07:27:37Z

After mm.h was removed from the asm-generic version of cacheflush.h, s390 allyesconfig shows several warnings of the following nature: In file included from arch/s390/include/generated/asm/cacheflush.h:1, from drivers/media/platform/omap3isp/isp.c:42: include/asm-generic/cacheflush.h:16:42: warning: 'struct mm_struct' declared inside parameter list will not be visible outside of this definition or declaration As Geert and Laurent point out, this driver does not need this header in the two files that include it. Remove it so there are no warnings.

asm-generic: don't include in cacheflush.h

2020-06-08T18:05:57Z

This seems to lead to some crazy include loops when using asm-generic/cacheflush.h on more architectures, so leave it to the arch header for now.

media: Split v4l2_pipeline_pm_use into v4l2_pipeline_pm_{get, put}

2020-03-02T14:11:40Z

Currently, v4l2_pipeline_pm_use() prototype is: int v4l2_pipeline_pm_use(struct media_entity *entity, int use) Where the 'use' argument shall only be set to '1' for enable/power-on, or to '0' for disable/power-off. The integer return is specified as only meaningful when 'use' is set to '1'. Let's enforce this semantic by splitting the function in two: v4l2_pipeline_pm_get and v4l2_pipeline_pm_put. This is done for several reasons. It makes the API easier to use (or harder to misuse). It removes the constraint on the values the 'use' argument shall take. Also, it removes the need to constraint the return value, by making v4l2_pipeline_pm_put void return. And last, it's more consistent with other kernel APIs, such as the runtime pm APIs, which makes the code more symmetric.

media: omap3isp: Prevent enabling CCDC when stopping streaming

2020-02-27T20:25:51Z

Commit ... prevented restarting CCDC through its interrupt handler when it's about to be disabled. It missed to address the case when CCDC might be enabled due to queueing a buffer. Do that now.

media: omap3isp: Don't restart CCDC if we're about to stop

2020-01-03T15:35:41Z

The omap3isp driver set the new buffer and enabled the CCDC in a situation a new buffer was available but streaming was about to be stopped on the CCDC. This lead to frequent system crashes in case there were buffers queued when streming was being stopped. Fix this by first checking whether there's an intent to stop streaming and if there isn't, then set the new buffer and re-enable CCDC. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
