* [media] v4l: tvp5150: Don't override output pinmuxing at stream on/off timeLaurent Pinchart2016-12-211-14/+19
| | | | | | | | | | | | | | | | The s_stream() handler incorrectly writes the whole MISC_CTL register to enable or disable the outputs, overriding the output pinmuxing configuration. Fix it to only touch the output enable bits. The CONF_SHARED_PIN register is also written by the same function, resulting in muxing the INTREQ signal instead of the VBLK/GPCL signal on the INTREQ/GPCL/VBLK pin. As the driver doesn't support interrupts this is obviously incorrect, and breaks operation on other devices. Fix it by removing the write.

* [media] v4l: tvp5150: Fix comment regarding output pin muxingLaurent Pinchart2016-12-211-7/+17
| | | | | | | | | | | | | | | The FID/GLCO/VLK/HVLK and INTREQ/GPCL/VBLK pins are muxed differently depending on whether the input is an S-Video or composite signal. The comment that explains the logic doesn't reflect the code. It appears that the comment is incorrect, as disabling the output data bus in composite mode makes no sense. Update the comment to match the code. While at it define macros for the MISC_CTL register bits, the code is too confusing with numerical values.

* [media] v4l: tvp5150: Reset device at probe time, not in get/set format handlersLaurent Pinchart2016-12-211-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The tvp5150 doesn't support format setting through the subdev pad API and thus implements the set format handler as a get format operation. The single handler, tvp5150_fill_fmt(), resets the device by calling tvp5150_reset(). This causes malfunction as the device can be reset at will, possibly from userspace when the subdev userspace API is enabled. The reset call was added in commit ec2c4f3f93cb ("[media] media: tvp5150: Add mbus_fmt callbacks"), probably as an attempt to set the device to a known state before detecting the current TV standard. However, the get format handler doesn't access the hardware to get the TV standard since commit 963ddc63e20d ("[media] media: tvp5150: Add cropping support"). There is thus no need to reset the device when getting the format. However, removing the tvp5150_reset() from the get/set format handlers results in the function not being called at all if the bridge driver doesn't use the .reset() operation. The operation is nowadays abused and shouldn't be used, so shouldn't expect bridge drivers to call it. To make sure the device is properly initialize, move the reset call from the format handlers to the probe function.

| | | | | | | | | | | | | | | | Unfortunately, KERN_CONT doesn't work with dev_foo(), producing weird messages like: tvp5150 6-005c: tvp5150: read 0xf6 = 0xff ff So, we need to get rid of it.

* [media] tvp5150: use sd internal ops .registered instead .registered_asyncJavier Martinez Canillas2016-08-241-2/+6
| | | | | | | | | | | | | | | | | The driver is using the struct v4l2_subdev_core_ops .registered_async callback to register the connector entities and create the pad links after the subdev entity has been registered with the media device. But the .registered_async callback isn't needed since the v4l2 core already calls the struct v4l2_subdev_internal_ops .registered callback in v4l2_device_register_subdev(), after media_device_register_entity(). So, use the .registered() callback instead of the .registered_async() that is going to be removed in a following patch since isn't needed.

* [media] tvp5150: return I2C write operation failure to callersJavier Martinez Canillas2016-05-091-2/+4
| | | | | | | | | | | | | | | | | | | The tvp5150_write() function calls i2c_smbus_write_byte_data() that can fail but does not propagate the error to the caller. Instead it just prints a debug, so callers can't know if the operation failed. So change the function to return the error code to the caller so it knows that the write failed and also print an error instead of just printing a debug information. While being there remove the inline keyword from tvp5150_write() to make it consistent with tvp5150_read() and also because it's called in a lot of places, so making inline is in fact counter productive since it makes the kernel image size to be much bigger (~16 KiB).

| | | | | | | | | | | | | | | | | | | | | | | | | | The tvp5150 decoder has different input connectors. The actual list of HW inputs depends on the device version but all have at least these 3: 1) Composite0 2) Composite1 3) S-Video and some variants have a 4th possible input connector: 4) Signal generator The driver currently uses the .s_routing callback to switch the input connector but since these are separate HW blocks, it's better to use media entities to represent the input connectors and their source pads linked with the decoder's sink pad. This allows user-space to use the MEDIA_IOC_SETUP_LINK ioctl to choose the input connector. For example using the media-ctl user-space tool: $ media-ctl -r -l '"Composite0":0->"tvp5150 1-005c":0[1]' Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | | | | | | | | | | | | | | | After power-up, the tvp5150 decoder is in a unknown state until the RESETB pin is driven LOW which reset all the registers and restarts the chip's internal state machine. The init sequence has some timing constraints and the RESETB signal can only be used if the PDN (Power-down) pin is first released. So, the initialization sequence is as follows: 1- PDN (active-low) is driven HIGH so the chip is power-up 2- A 20 ms delay is needed before sending a RESETB (active-low) signal. 3- The RESETB pulse duration is 500 ns. 4- A 200 us delay is needed for the I2C client to be active after reset.

| | | | | | | | | | | | | | As discussed on the media summit 2013, there is no reason for the width and height to be signed.
