Antti Palosaari authored
Define tuner types V4L2_TUNER_ADC and V4L2_TUNER_RF for SDR usage. ADC is used for setting sampling rate (sampling frequency) to SDR device. Another tuner type, named as V4L2_TUNER_RF, is possible RF tuner. Is is used to down-convert RF frequency to range ADC could sample. Having RF tuner is optional, whilst in practice it is almost always there. Also add checks to VIDIOC_G_FREQUENCY, VIDIOC_S_FREQUENCY and VIDIOC_ENUM_FREQ_BANDS only allow these two tuner types when device type is SDR (VFL_TYPE_SDR). For VIDIOC_G_FREQUENCY we do not check tuner type, instead override type with V4L2_TUNER_ADC in every case (requested by Hans in order to keep functionality in line with existing tuners and existing API does not specify it). Prohibit VIDIOC_S_HW_FREQ_SEEK explicitly when device type is SDR, as device cannot do hardware seek without a hardware demodulator. Signed-off-by:

Add new video4linux device named /dev/swradio for Software Defined Radio use. V4L device minor numbers are allocated dynamically nowadays, but there is still configuration option for old fixed style. Add note to mention that configuration option too. Signed-off-by:

Currently, there's just one device using this frontend: PCTV 80e, and it works on serial mode. Change the default here to serial mode. If we add more devices, then this option should be set via config structure. Acked-by:

DJH_DEBUG only code path in drxbsp_i2c_write_read() dereferences w_dev_addr and subsequently w_dev_addr->user_data->i2c which results in failure during boot. This patch fixes the null pointer derefence bug as well as the following compile errors: LD arch/x86/built-in.o CC drivers/media/dvb-frontends/drx39xyj/drxj.o drivers/media/dvb-frontends/drx39xyj/drxj.c: In function ‘drxbsp_i2c_write_read’: drivers/media/dvb-frontends/drx39xyj/drxj.c:1558:25: error: redeclaration of ‘state’ with no linkage struct drx39xxj_state *state = w_dev_addr->user_data; ^ drivers/media/dvb-frontends/drx39xyj/drxj.c:1512:25: note: previous declaration of ‘state’ was here struct drx39xxj_state *state; ^ drivers/media/dvb-frontends/drx39xyj/drxj.c:1558:2: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement] struct drx39xxj_state *state = w_dev_addr->user_data; ^ drivers/media/dvb-frontends/drx39xyj/drxj.c:1560:17: error: redeclaration of ‘msg’ with no linkage struct i2c_msg msg[2] = { ^ drivers/media/dvb-frontends/drx39xyj/drxj.c:1513:17: note: previous declaration of ‘msg’ was here struct i2c_msg msg[2]; ^ Signed-off-by:Shuah Khan <shuah.kh@samsung.com> Acked-by:

There are no other I2C masters here. Also, the Windows driver uses this mode (and both drxd and drxk Kernel drivers). So, switch to it. That helps to compare the logs between the Linux driver and the Windows one. Acked-by:

This file contains an abstract layer for the I2C transfer functions. Get rid of it, merging it at drxj. This will allow to remove another abstraction layer there, making the code easier to read, and removing the functions that just return -EIO. Acked-by:

QAM/256 currently doesn't work, as the code is only called if channel->mirror is DRX_MIRROR_AUTO, but a prevous if prevents this condition to happen. While here, returns -EINVAL to not supported QAM modes and simplify the code, reducing the number of indents. Acked-by:

Checking if a time is after another one can have issues, as times are generally u32 wide. Use the proper macros for that at scu_command(). It should be noticed that other places also use jiffies calculus on an improper way. This should be fixed too, but the logic there is more complex. So, let's do it in separate patches. Acked-by:

Modulation and other parameters might have changed. So, better to call ctrl_set_standard() even if the device is already powered. That helps to put the device into a sane state, if something got wrong on a previous set_frontend call. Acked-by:
