This patch adds support for G-Scaler (Generic Scaler) device which is a new device for scaling and color space conversion on EXYNOS5 SoCs. This patch adds the code for register definitions and register operations. This device supports the followings as key feature. 1) Input image format - RGB888/565, YUV422 1P/2P, YUV420 2P/3P, TILE 2) Output image format - RGB888/565, YUV422 1P/2P, YUV420 2P/3P, YUV444 3) Input rotation - 0/90/180/270 degree, X/Y Flip 4) Scale ratio - 1/16 scale down to 8 scale up 5) CSC - RGB to YUV / YUV to RGB 6) Size - 2048 x 2048 for tile or rotation - 4800 x 3344 other case Signed-off-by:

This is workaround / partial fix. rtl2832u_power_ctrl() and rtl2832u_frontend_attach() needs to be go through carefully and fix properly. There is clearly some logical errors when handling power-management ang GPIOs... Signed-off-by:

Changing cached frequency during init is something no-no. Make it behave a little bit better. After that device could survive from suspend/resume when streaming is ongoing. Signed-off-by:

ite_dev::rdev is currently initialised in ite_probe() after rc_register_device() returns. If a newly registered device is opened quickly enough, we may enable interrupts and try to use ite_dev::rdev before it has been initialised. Move it up to the earliest point we can, right after calling rc_allocate_device(). Reported-and-tested-by:

[media] gspca_pac7302: avoid duplicate calls of the image quality adjustment functions on capturing start There is no need to call the image quality adjustment functions in sd_start. The gspca main driver calls v4l2_ctrl_handler_setup in gspca_init_transfer, which already applies all image control values. Signed-off-by:

1) We always re-create the input-urb on resume, so we must also always destroy it on suspend to avoid leaking it 2) If we're going to do an init_transfer, then that will destroy the urb before starting the stream (nop if there is none), and (re-)create it once the stream is started. So there is little use in creating it, if we're going to do an init_transfer immediately afterward Signed-off-by:

gspca_main: init_transfer does not do anything between calling sd_start (which starts the workqueue) and releasing the usb_lock, so this synchronization is a nop, remove it. Signed-off-by:

In commit a3d6e8cc gspca_dev->dev is set to NULL on disconnect, before calling stop0. The plan was to get rid of gspca_dev->present and instead simply check for gspca_dev->dev everywhere where we were checking for present. This should be race free since all users of gspca_dev->dev hold the usb_lock, or so I thought. But I was wrong, drivers which use a work-queue + synchronous bulk transfers to get the video data don't hold the usb_lock while doing so, their stop0 callbacks stop the workqueue, so they won't be using gspca_dev->dev anymore after the stop0 call, but they might be dereferincing it before, so we should not set gspca_dev->dev to NULL on disconnect before calling stop0. This also means that the workqueue functions in these drivers cannot use gspca_dev->dev to check if they need to stop because of disconnection, so we will need to keep gspca_dev->present around, and set that to 0 on disconnect, before calling stop0. Unfortunately as part of the plan to remove gspca_dev->present, these workqueues where already moved over to checking for gspca_dev->dev instead of gspca_dev->present as part of commit 254902b0, so this patch also reverts those parts of that commit.
