While debugging, it's currently really hard to identify controls by their ID. Print the control name making the print more helpful. With this change, the print changes from: video1: VIDIOC_S_EXT_CTRLS: which=0xf010000, count=5, error_idx=4, request_fd=45, id/size=0x990ce8/1048, id/size=0x990ce9/12, id/size=0x990cea/480, id/size=0x990ceb/896, id/size=0x990cec/400 video1: VIDIOC_S_EXT_CTRLS: which=0xf010000, count=5, error_idx=4, request_fd=42, name=H264 Sequence Parameter Set, id/size=0x990ce8/1048, name=H264 Picture Parameter Set, id/size=0x990ce9/12, name=H264 Scaling Matrix, id/size=0x990cea/480, name=H264 Slice Parameters, id/size=0x990ceb/896, name=H264 Decode Parameters, id/size=0x990cec/400 For instance, this is specially helpful when the ioctl fails.

VDE partition is left turned ON after bootloader on most devices, hence let's ensure that it's turned OFF in order to lower power leakage while hardware is idling by turning it ON and OFF during of the driver's probe. Signed-off-by:

On some devices bootloader isn't ready to a clamped VDE power, and thus, machine hangs on a warm reboot (CPU reset). The VDE power partition is turned ON by default on a cold boot, hence VDE driver should keep power partition enabled on system's reboot too. This fixes hang on a warm reboot on a Tegra20 Acer A500 device, which is handy if Embedded Controller driver is unavailable, i.e. cold reboot can't be performed. Signed-off-by:

Do not fail probing when device_init_wakeup fails. device_init_wakeup fails when the device is already enabled as wakeup device. Hence, the driver fails to probe the device if: - The device has already been enabled for wakeup (by e.g. sysfs) - The driver has been unloaded and is being loaded again. This goal of the patch is to fix the above cases. Overwhelming majority of the drivers do not check device_init_wakeup return code.

Setting the output CSC mode is required for a YUV output, but must not be set when the input is also YUV. Doing this (as tested with a YUV420P to YUV420P conversion) results in wrong colors. Adapt the logic to only set the output CSC mode when the output is YUV and the input is RGB. Also add a comment to clarify the rationale.

This introduces two macros: RGA_COLOR_FMT_IS_YUV and RGA_COLOR_FMT_IS_RGB which allow quick checking of the colorspace familily of a RGA color format. These macros are then used to refactor the logic for CSC mode selection. The two nested tests for input colorspace are simplified into a single one, with a logical and, making the whole more readable. Signed-off-by:

It's not possible for "pcdev->mclk" to be zero because we check for that earlier and set it to 20000000 in that situation. If it were possible, that would be a problem because it could have lead to an Oops in the error handling when we call v4l2_clk_unregister(pcdev->mclk_clk); Signed-off-by:

Since the driver was picked-up the starting of the PHY have changed quiet a bit. An artifact of these changes is the now poorly named callback confirm_start(). It used to confirm start of the PHY but now performs post PHY start initialization, rename it to phy_post_init() to reflect this. Signed-off-by:

Add bit-depth change as one more reason which could change in the middle of the stream. For the worst case the stream is 8bit at the beginning but later in the bit-stream it changes to 10bit. That change should be propagated to the client so that it can take the appropriate action. In that case it has to stop the streaming on the capture queue, re-negotiate the pixel format, allocate new buffers and start the streaming again. Signed-off-by:

Fix up inconsistent usage of upper and lowercase letters in "Samsung" and "Exynos" names. "SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked names. Therefore they should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website. Although advertisement materials usually use uppercase "SAMSUNG", the lowercase version is used in all legal aspects (e.g. on Wikipedia and in privacy/legal statements on https://www.samsung.com/semiconductor/privacy-global/).

When debugging issues that involve more than one video queue, messages related to multiple queues get interleaved without any easy way to tell which queue they relate to. Fix this by adding a queue name to vb2_queue, and printing it in all debug messages in the vb2 core and V4L2 layers. If the name isn't set by drivers, it is automatically filled with the queue direction and address. Signed-off-by:
