* [media] si470x: don't use buffer on the stack for USB transfersHans Verkuil2013-12-18
| | | | | | | | You shouldn't use buffers allocated on the stack for USB transfers, always kmalloc them. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

* [media] radio-si470x: Fix band selectionHans de Goede2012-07-30
| | | | | | | | The mask was wrong resulting in band 0 and 1 always ending up as band 0 in the register. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] radio-si470x: Lower firmware version requirementsHans de Goede2012-07-30
| | | | | | | | | Testing with a firmware version 12 usb radio stick has shown version 12 to work fine too. Reported-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] radio-si470x: Lower firmware version requirementsHans de Goede2012-07-30
| | | | | | | | With the changes from the previous patches device firmware version 14 + usb microcontroller software version 1 works fine too. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] radio-si470x: Always use interrupt to wait for tune/seek completionHans de Goede2012-07-30
| | | | | | | | | | | | Since USB receives STATUS_RSSI updates through the interrupt endpoint, there is no need to poll with USB, so get rid of the polling. Note this also changes the order in which the probing of USB devices is done, to avoid si470x_set_chan getting called before the interrupt endpoint is being monitored.

* [media] radio-si470x: Don't unnecesarily read registers on G_TUNERHans de Goede2012-07-30
| | | | | | | | | | | | | | | | | | | | | | Reading registers from the pcear USB dongles with the si470x causes a loud pop (and an alsa buffer overrun). Since most radio apps periodically call G_TUNER to update mono/stereo, signal and afc status this leads to the music . pop . music . pop . music -> not good. On the internet there is an howto for flashing the pcear with a newer firmware from the silabs reference boardto fix this, but: 1) This howto relies on a special version of the driver which allows firmware flashing 2) We should try to avoid the answer to a bug report being upgrade your firmware, if at all possible 3) Windows does not suffer from the pop sounds After a quick look at the driver I found at that the register reads are not necessary at all, as the device gives us the necessary status through usb interrupt packets, and the driver already uses these!

* [media] si470x: Clean up, introduce the control frameworkHans Verkuil2012-05-14
| | | | | | | | | This cleans up the code and si470x now uses the proper v4l2 frameworks and passes most of the v4l2-compliance tests. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Acked-by: Tobias Lorenz <tobias.lorenz@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] radio: Use the subsystem version control for VIDIOC_QUERYCAPMauro Carvalho Chehab2011-07-27
| | | | | | | | Just like the video drivers, the right thing to do is to use the per-subsystem version control. Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] radio-si470x: support seek and tune interrupt enableJoonyoung Shim2011-05-20
| | | | | | | | | Currently we use busy waiting to seek and tune, it can replace to interrupt way. SI470X I2C driver supports interrupt way to week and tune via this patch. Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] saa6588: rename rds.h to saa6588.hHans Verkuil2010-12-29
| | | | | | | | | | | | | | | The naming of the media/rds.h header suggested that it was a generic RDS header, when in fact it is just a saa6588 module API that is internal to the kernel. Rename the header and the struct and defines in it to make this clear. Also removed the header include in radio-si470x.h (not used anymore) and from ioctl-number.txt (it's internal to the kernel and never called from userspace).

* BKL: remove extraneous #include <smp_lock.h>Arnd Bergmann2010-11-17
| | | | | | | | | | The big kernel lock has been removed from all these files at some point, leaving only the #include. Remove this too as a cleanup. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* V4L/DVB (13600): radio-si470x: support RDS on si470x i2c driverJoonyoung Shim2009-12-15
| | | | | | | | | | | This patch is to support RDS on si470x i2c driver. The routine of RDS operation is almost same with thing of usb driver, but this uses RDS interrupt.

| | | | | | | | | | The read and poll file operations of the si470x usb driver can be used also equally on the si470x i2c driver, so they go to the common file.

* V4L/DVB (12417): I2C cleanups and version checksTobias Lorenz2009-09-12
| | | | | | | | | | | The structure and comments of the I2C part have been adopted to fit to the USB part. Some additional cleanups and precisements have been made to the version detection and checking functionality to clearly separate HW/SW/FW version.

* V4L/DVB (12416): radio-si470x: add i2c driver for si470xJoonyoung Shim2009-09-12
| | | | | | | | | | | | | This patch supports i2c interface of si470x. The i2c specific part exists in radio-si470x-i2c.c file and the common part uses radio-si470x-common.c file. The '#if defined' is inserted inevitably because of parts used only si470x usb in the common file. The current driver version doesn't support the RDS.

* V4L/DVB (12413): radio-si470x: separate common and usb codeJoonyoung Shim2009-09-12
This patch is a preceding work to add the i2c interface of si470x. The si470x directory includes a common file and usb specific file and header file. The part unrelated with usb interface and i2c interface exists in radio-si470x-common.c file, and The usb specific part exists in radio-si470x-usb.c file.
