The corresponding API for clk_prepare_enable is clk_disable_unprepare, other than clk_disable. Fix this by changing clk_disable to clk_disable_unprepare. Fixes: b4155d7d ("[media] exynos4-is: Ensure fimc-is clocks are not enabled until properly configured") Signed-off-by:

The RDACM20 camera supports a single image format which is currently listed as MEDIA_BUS_FMT_UYVY8_2X8. As the video stream is transmitted on the GMSL serial bus, the 2X8 variant does not apply. Fix the format by using MEDIA_BUS_FMT_UYVY8_1X16. This fixes a runtime error which is now triggered as the MAX9286 deserializer implements .link_validate(). Signed-off-by:

Add a check to make sure the input interface (CSI-2 or parallel) allow for the requested input bus format. If not inform the user and error out rather then try to continue with incorrect settings. While at it add the missing define for RGB666 that is not yet supported in the driver but we can preemptively check for it in this context already. Signed-off-by:

Commit 46fb9995 ("media: platform: place NXP drivers on a separate dir") moves various files in media/platform into a nxp subdirectory. It adjusts the section MEDIA DRIVER FOR FREESCALE IMX PXP in MAINTAINERS, but misses some references in NXP i.MX 8QXP/8QM JPEG V4L2 DRIVER and MEDIA DRIVERS FOR FREESCALE IMX7. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference.

smb_word_op() has a parameter data_format that determines if the data is either a byte or word. From inspection, smb_word_op() is only used by the macros smb_wr16() and smb_rd16() both pass in CMD_WORD_DATA. There is no use of smb_word_op() that passes in CMD_BYTE_DATA. So remove the byte handling. Signed-off-by:

So use the latter both in the error handling path of the probe and in the remove function. It is easier to see the relation with aspeed_video_alloc_buf() this way.

This patch aims to add UVC_GUID_FORMAT_H265 High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2. They describe the same video encoding method. So for handling their behavior is the same. However, when external camera device describes this encoding method, some use hevc, some use h265. There is no uniform specification to describe this encoding method. So if an external camera device use h265 to describe this encoding method, driver will not recognize it. Therefore, this patch is to enable driver to read HEVC/H265 and convert it to V4L2_PIX_FMT_HEVC. Signed-off-by:

The list iterator will point to a bogus position containing HEAD if the list is empty or the element is not found in list. This case should be checked before any use of the iterator, otherwise it will lead to a invalid memory access. The missing check here is before "pin = iterm->id;", just add check here to fix the security bug. In addition, the list iterator value will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the element is not found in list, considering the (mis)use here: "if (iterm == NULL". Use a new value 'it' as the list iterator, while use the old value 'iterm' as a dedicated pointer to point to the found element, which 1. can fix this bug, due to 'iterm' is NULL only if it's not found. 2. do not need to change all the uses of 'iterm' after the loop. 3. can also limit the scope of the list iterator 'it' *only inside* the traversal loop by simply declaring 'it' inside the loop in the future, as usage of the iterator outside of the list_for_each_entry is considered harmful. https://lkml.org/lkml/2022/2/17/1032 Fixes: d5e90b7a ("[media] uvcvideo: Move to video_ioctl2") Signed-off-by:

The mipi_csis_dump_regs() function accesses the interface registers in order to printout their values for debug purposes. As the function access the registers, it requires the interface to be powered up. Currently this is only enforced in one of the function's callers (mipi_csis_log_status)() but not when the function is called by the debugfs attribute handler. Make sure to access registers only if the interface is powered up and remove the same check from the caller. Signed-off-by:

The mipi_csis_device.powered flag only serves for the purpose of not accessing registers in mipi_csis_log_status() when the interface is not powered up. Instead of manually tracking the power state, rely on pm_runtime_get_if_in_use() to remove the 'powered' flag. Also remove the locking in the function as runtime_pm() is refcounted and there's no risk of the interface being powered down behind our backs. Signed-off-by:

The subdev .s_power() operation is deprecated. Drop it, requiring sensor drivers to correctly use runtime PM instead of relying on .s_power(). As this driver has just been moved out of staging, and necessary drivers to implement a full camera pipeline are still in staging, no platform depends yet on this API being called. There is thus no risk of regression. Signed-off-by:
