media: platform: rename am437x/ to ti/am437x/

2022-03-18T04:58:34Z

As the end goal is to have platform drivers split by vendor, rename am437x/ to ti/am437x/. Reviewed-by: Laurent Pinchart Reviewed-by: Lad Prabhakar Signed-off-by: Mauro Carvalho Chehab

media: platform: move platform menu dependencies to drivers

2022-03-14T08:42:59Z

Right now, platform dependencies are organized by the type of the platform driver. Yet, things tend to become very messy with time. The better seems to organize the drivers per manufacturer, as other Kernel subsystems are doing. As a preparation for such purpose, get rid of menuconfigs, moving the per-menu dependencies to be at the driver-specifig config entires. This shoud give flexibility to reorganize the platform drivers per manufacturer and re-sort them. This patch removes all "if..endif" options from the platform Kconfig, converting them into depends on. Acked-by: Jernej Skrabec Signed-off-by: Mauro Carvalho Chehab

media: am437x: Make use of the helper function devm_platform_ioremap_resource()

Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l: async: Rename async nf functions, clean up long lines

2021-09-30T08:07:35Z

Rename V4L2 async notifier functions, replacing "notifier" with "nf" and removing "_subdev" at the end of the function names adding subdevs as you can only add subdevs to a notifier. Also wrap and otherwise clean up long lines. Signed-off-by: Sakari Ailus Reviewed-by: Jacopo Mondi Reviewed-by: Rui Miguel Silva (imx7) Signed-off-by: Mauro Carvalho Chehab

media: am437x: fix pm_runtime_get_sync() usage count

2021-05-10T09:36:33Z

The pm_runtime_get_sync() internally increments the dev->power.usage_count without decrementing it, even on errors. Replace it by the new pm_runtime_resume_and_get(), introduced by: commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") in order to properly decrement the usage counter, avoiding a potential PM usage counter leak. While here, ensure that the driver will check if PM runtime resumed at vpfe_initialize_device(). Reviewed-by: Jonathan Cameron Signed-off-by: Mauro Carvalho Chehab

media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() API

2021-02-06T08:18:53Z

The functions that add an async subdev to an async subdev notifier take as an argument the size of the container structure they need to allocate. This is error prone, as passing an invalid size will not be caught by the compiler. Wrap those functions in macros that take a container type instead of a size, and cast the returned pointer to the desired type. The compiler will catch mistakes if the incorrect type is passed to the macro, as the assignment types won't match.

media: Kconfig files: use select for V4L2 subdevs and MC

2020-04-14T08:29:05Z

There are lots of drivers that only work when the media controller and/or the V4L2 subdev APIs are present. Right now, someone need to first enable those APIs before using those drivers. Well, ideally, drivers, should, instead *optionally* depend on it, in order for PC camera drivers to be able to use them, but nowadays most drivers are UVC cameras, with don't require a sensor driver. So, be it. Let's instead make them select the MEDIA_CONTROLLER and the SUBDEV API, in order to make easier for people to be able of enabling them. Signed-off-by: Mauro Carvalho Chehab

media: am437x-vpfe: exclude illegal values for enum when validing params from user space

2020-03-12T15:26:15Z

When calling ccdc_data_size_max_bit() to validate data_sz in vpfe_ccdc_validate_param(), it's treated as an enumeration ranging from 0 to 7 while essentially it's an 32 bit unsigned integer directly from user space. This can make the return value of ccdc_data_size_max_bit() underflow and bypass the following check. To fix this, an additional check is added to the following if clause to keep this enumaration variable in range. And if its value is not legal, return -EINVAL properly.
