Remove a hack I had put in to force the firmware to be 8MHz, now setting the firmware properly based on the target standard. Signed-off-by:

Based on a reference trace under Windows, reverse engineer the PLL config. Note that the xtal is not yet setup, and the timf cannot be determined yet because my reference trace doesn't actually achieve a signal lock. Signed-off-by:

It was confirmed by DibCom that i2c stretching is broken in the i2c master on the dib7700. So we need to put a hack into the xc4000 driver to not complain in certain very specific cases where we know i2c stretching occurs. Signed-off-by:

Properly setup the standard firmware loading and scode loading, as well as getting rid of a ton of dead code. Note that I am getting a single i2c error when the standard firmware sets the video standard, but everything else seems to be loading properly now. Signed-off-by:

Add code to handle firmware blobs for the standard and scode. Note there appears to be some issue with loading the DTV8 standard firmware, probably related to direct/indirect mode. Signed-off-by:

Since we use the xc3028 version of the firmware file parsing routine (which includes support for scodes and separate blobs), we can drop the xc5000 version of the code. Signed-off-by:

Devin Heitmueller authored
The xc4000 driver is based on the original xc5000 driver, and while the xc5000 supports the XREG_BUSY register, the xc4000 does not. So remove the code in question. Signed-off-by:

We need to set the firmware type properly in order to locate the init1 firmware. Signed-off-by:

The xc3028 version does i2c splitting in a different manner than xc4000 and xc5000, so reuse the xc5000 version of the routine (the key here being that xc4000 expects the first *two* bytes to be the same for splitting transactions. Doing it the xc3028 way was resulting in i2c errors partially through the firmware load. With this change, it would appear that the entire base firmware is being loaded successfully (product id now properly shows 0x0FA0). Signed-off-by:

Switch over to using the firmware management routines from the tuner-xc2028, since that has support for scodes, etc. This code still requires signficant cleanup, and at this point the base firmware does not load properly (i2c write errors about 300 bytes in). Signed-off-by:

We need to set the dev.parent member on the dib7000p on its i2c master, or else calls to request_firmware() will hit an oops in 2.6.31. Signed-off-by:

Add a sleep since in some cases the dib7000p wasn't online when being probed. The optimal timing has not yet been determined. Signed-off-by:

Provide a frontend setup routine for the PCTV 340e which takes into account the specific GPIO setup of the board. Note that this patch does *not* take into account the xc4000 reset pin, which is attached to the dib7000. Signed-off-by:

This is initial code written by Davide Ferri for the PCTV 340e, including a new xc4000 driver. I am checking in all the code unmodified, and making no assertions about its quality (other than confirming it compiles). [mchehab@redhat.com: rebased on the top of the current tree] Signed-off-by:

The implementation of the gain calculation for this sensor is incorrect. It is only working for the first 127 values. The reason is, that the gain cannot be set directly by writing a value into the gain registers of the sensor. The gain register work this way (see datasheet page 24): bits 0 to 6 are called "initial gain". These are linear. But bits 7 and 8 ("analog multiplicative factors") and bits 9 and 10 ("digital multiplicative factors") work completely different: Each of these bits increase the gain by the factor 2. So if the bits 7-10 are 0011, 0110, 1100 or 0101 for example, the gain from bits 0-6 is multiplied by 4. The order of the bits 7-10 is not important for the resulting gain. (But there are some recommended values for low noise) The current driver doesn't do this correctly: If the current gain is 000 0111 1111 (127) and the gain is increased by 1, you would expect the image to become brighter. But the image is completly dark, because the new gain is 000 1000 0000 (128). This means: Initial gain of 0, multiplied by 2. The result is 0. This patch adds a new function which does the gain calculation and also fixes the same bug for red_balance and blue_balance. Additionally, the driver follows the recommendation from the datasheet, which says, that the gain should always be above 0x0020.

There are problems when you use this camera/sensor in a very bright room or outside. The image is completely white, because it is overexposed. The driver uses a default value which is not suitable for all environments. This patch makes it possible to adjust the exposure time by youself. I found out by logging the i2c-data, that the windows driver for this sensor is doing this, too. I tested the camera on a sunny day and after adjusting the exposure time, I was able to see a very good image. Tested-by:

According to the datasheet (page 8), the first optical clear pixel-column is not at position 14. The correct/recommended value is 20. Without this patch there is a dark line on the left side of the image. Tested-by:

If change_protocol() fails and we goto out_raw, then it calls unlock twice. I noticed that the other time we called change_protocol() we held the &dev->lock, so I changed it to hold it here too. Reviewed-by:

The function "rc5_scan" in "dvb_usb.h" is returning invalid value. The value should be returned "u16" but is returning "u8". See example below in "drivers/media/dvb/dvb-usb/opera1.c": send_key = (send_key & 0xffff) | 0x0100; for (i = 0; i < ARRAY_SIZE(rc_map_opera1_table); i++) { if (rc5_scan(&rc_map_opera1_table[i]) == (send_key & 0xffff)) { *state = REMOTE_KEY_PRESSED; *event = rc_map_opera1_table[i].keycode; opst->last_key_pressed = rc_map_opera1_table[i].keycode; break; } opst->last_key_pressed = 0; } Signed-off-by:Manoel Pinheiro <pinusdtv@hotmail.com> Signed-off-by:

Convert radio-sf16fmr2 to use generic TEA575x implementation. Most of the driver code goes away as SF16-FMR2 is basically just a TEA5757 tuner connected to ISA bus. The card can optionally be equipped with PT2254A volume control (equivalent of TC9154AP) - the volume setting is completely reworked (with balance control added) and tested. Signed-off-by:

Convert tea575x-tuner to use the new V4L2 control framework. Also add ext_init() callback that can be used by a card driver for additional initialization right before registering the video device (for SF16-FMR2). Also embed struct video_device to struct snd_tea575x to simplify the code. Signed-off-by:
