* [media] solo6x10: use v4l2_get_timestamp to fill in buffer timestampHans Verkuil2015-12-181-2/+1
| | | | | | | | | | The timestamp of a v4l2_buffer was advertised as being CLOCK_MONOTONIC, but instead a timestamp from a header field was used. This is inconsistent and not what applications expect. Use v4l2_get_timestamp to properly set the timestamp.

* [media] vb2: drop v4l2_format argument from queue_setupHans Verkuil2015-12-1879-497/+328
| | | | | | | | | | | | | | | | | | | | | The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | | | For those two devices the code wrote to addresses 0x115/6, but on those devices those addresses have nothing to do with power controls. So clearly this never worked.

| | | | | | | | | | | | | | | | | | | | | | The cx23888 also moves the following registers around: !cx23888 cx23888 -------- ------- 0x418, 0x41c 0x434, 0x438 0x420 0x418 (expect for bit 29 which has a different meaning) 0x478 0x454 Also drop the set_input code where the scaler is changed: this does not belong here, changing the input should not change the scaler. And that's besides the fact that that code is plain wrong. After this change the cx23888 behaves much better. In particular, calling set_input no longer changes the saturation to 0, causing a grayscale image.

* [media] cx23885: fix format/crop handlingHans Verkuil2015-12-182-6/+38
| | | | | | | | | | | | | | | | While testing the cx23885 driver with various TV standards I found a number of bugs: 1) norm_maxw() returned 768 instead of 720 for PAL formats. This should always be 720, so drop this inline function and just always use 720. 2) cropcap() was missing, so the pixelaspect was never known and qv4l2 would scale the image incorrectly. Add cropcap support. 3) cx23885_set_tvnorm() should just return 0 if the same standard was set again. If another standard is set, then reset the width/height and call set_fmt for the subdevs. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] staging: media: lirc: Replace timeval with ktime_t in lirc_parallel.cArnd Bergmann2015-12-031-20/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'struct timeval tv' and 'struct timeval now' is used to calculate the elapsed time. 'LIRC_SFH506_DELAY' is a delay t_phl in usecs. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the lirc_parallel.c file of media: lirc driver to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub is used to subtract two ktime variables. ktime_to_us() is used to convert ktime to microsecond. New ktime_t variable timeout, is added in lirc_off(),to improve clarity. Introduced a new ktime_t variable in lirc_lirc_irq_handler() function, to avoid the use of signal variable for storing seconds in the first part of this function as later it uses a time unit that is defined by the global "timer" variable. This makes it more clear. ktime_set() is used to set a value in seconds to a value in nanosecond so that ktime_compare() can be used appropriately. ktime_compare() is used to compare two ktime values. ktime_add_ns() is used to increment a ktime value by 1 sec. One comment is also shifted a line up, as it was creating a 80 character warning. Build tested it. Also tested it with sparse.

| | | | | | | | | | | | | | | | | | | | | 'struct timeval presstime' and 'struct timeval tv' is used to calculate the time since the last button press. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the media: lirc driver to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub() are used to subtract two ktime variables. 'ms' is only used to check how much time has passed by comparing to 250. So instead of using expensive ktime_to_ms() call, it has been changed to hold nanoseconds by using ktime_to_ns().

| | | | | | | | | | | | | | | | | | | | | | | | | | | 'struct timeval tv' is used to get current time. 'static struct timeval lasttv' is used to get last interrupt time. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. This patch changes the lirc_serial.c file of media: lirc to use ktime_t. ktime_get() is better than using do_gettimeofday(), because it uses the monotonic clock. ktime_sub is used to subtract two ktime variables. The check to test time going backwards is also removed. Intialization to static variable is also removed. ktime_to_us() is used to convert ktime_t to microsecond value. deltv is changed to delkt, a ktime_t type varibale from long to assign the ktime_sub value directly. ktime_compare is used to compare delkt with 15 seconds, which is changed to a nanosecond value by using ktime_set().

This set does not include those for issues introduced during the merge window. Fixes of those will follow in a future series. * ad5064 - Make sure the local i2c_write returns 0 on success rather than the number of bytes transfered. Otherwise we report an error on all writes. - Fix a shift for ad5629 and ad5669 which gives incorrect DAC output on these parts. * ad7793 - The product ID on the datasheet is wrong. Fix it in the driver. * IIO_DUMMY_EVGEN - select IRQ_WORK as a dependency. * lpc32xx - make sure clock is prepared before enabling. * si7020 - data byte order was reversed. Fix it. * vf610 - Internal temperature calculation was wrong if a different reference voltage was used. Now use a linear interpolation function to make it work over the full range. - Fix a division by zero in the case of a device tree property not being present (same issue two fixes). * xilinx XADC - VREFN scale was wrong - fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The scaling factor for VREFN is 3.0/4096 (not 1.0/4096), just as for VREFP. This is not immediately obvious from the specification (Xilinx UG480), but has been confirmed by Xilinx support.
