2008-01-25radio-si570x: Some fixes and new USB ID additionMauro Carvalho Chehab
From: Tobias Lorenz <tobias.lorenz@gmx.net> - avoid poss. locking when doing copy_to_user which may sleep - RDS is automatically activated on read now - code cleaned of unnecessary rds_commands - USB Vendor/Product ID for ADS/Tech FM Radio Receiver verified (thanks to Guillaume RAMOUSSE) Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-01-25radio-si470x: Some cleanupsMauro Carvalho Chehab
From: Tobias Lorenz <tobias.lorenz@gmx.net> - code reordered to avoid function prototypes - switch/case defaults are now more user-friendly - unified comment style - applied all checkpatch.pl v1.12 suggestions except the warning about the too long lines with bit comments - renamed FMRADIO to RADIO to cut line length (checkpatch.pl) Signed-off-by: Tobias Lorenz <tobias.lorenz@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-01-15Adds the proper compatibility code for radio-si470x and stk-webcamMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Make radio-si470x and stk-webcam backward compatible with older kernels. This patch adds compat.h header for those files, reorder include order and adds USB_DEVICE_AND_INTERFACE_INFO macro. Thiw way, stk-webcam is backward compatible with 2.6.22, and radio-si470x with kernel 2.6.20. The backports weren't tested, but compile fine.

2008-01-14USB radio driver for Silicon Labs Si470x FM Radio ReceiversMauro Carvalho Chehab
From: Tobias Lorenz <tobias.lorenz@gmx.net> this patch adds a new driver for the Silicon Labs Si470x FM Radio Receiver. It should also work for the identical ADS/Tech FM Radio Receiver (formerly Instant FM Music) as soon as I find out the USB Vendor and Product ID. The driver is inspired by several other USB and radio drivers, but mainly from the D-Link DSB-R100 USB radio (dsbr100.c). The USB stick currently has an Si4701 FM RDS radio receiver. But the other Si470x devices are pin and register compatible, so that in the future the driver can easily be patched to support these too. Therefore I named the driver radio-si470x and the configuration option usb-si470x. The driver itself just provides the control function over the radio. For getting audio back, the device support the USB audio class, which is implemented in the already existing driver. I tested the driver in the last days, until it now satisfies all my functionality and robustness requirements. The application I used for testing was kradio.
