The driver itself is implemented as an MFD devices comprised of three parts: 1. Core device that provides all the other devices with basic functionality and locking scheme. 2. Radio device that translates between V4L2 subsystem requests into Core device commands. 3. Codec device that does similar to the earlier described task, but for ALSA SoC subsystem. v3 of this driver has following changes: - All custom ioctls were moved to be V4L2 controls or debugfs files - Chip properties handling was moved to regmap API, so this should allow for cleaner code, and hopefully more consistent behaviour of the driver during switch between AM/FM(wich involevs power-cycling of the chip) I was hoping to not touch the code of the codec driver, since Mark has already appplied the previous version, but because of the last item I had to. Unfotunately, since my ARM setup runs only 3.1 kernel, I was only able to test this driver on a standalone USB-connected board that has a dedicated Cortex M3 working as a transparent USB to I2C bridge which was connected to a off-the-shelf x86-64 laptop running Ubuntu with custom kernel compile form git.linuxtv.org/media_tree.git. Which means that I was unable to test the change in the codec code, except for the fact the it compiles. Here is v4l2-compliance output for one of the tuners(as per Hans' request): sudo v4l2-compliance -r /dev/radio0 is radio Driver Info: Driver name : si476x-radio0 Card type : SI476x AM/FM Receiver Bus info : platform:si476x-radio0 Driver version: 3.6.0 Capabilities : 0x81050500 RDS Capture Tuner Radio Read/Write Device Capabilities Device Caps : 0x01050500 RDS Capture Tuner Radio Read/Write Compliance test for device /dev/radio0 (not using libv4l2): Required ioctls: test VIDIOC_QUERYCAP: OK Allow for multiple opens: test second radio open: OK test VIDIOC_QUERYCAP: OK test VIDIOC_G/S_PRIORITY: OK Debug ioctls: test VIDIOC_DBG_G_CHIP_IDENT: OK test VIDIOC_DBG_G/S_REGISTER: OK test VIDIOC_LOG_STATUS: OK (Not Supported) Input ioctls: test VIDIOC_G/S_TUNER: OK test VIDIOC_G/S_FREQUENCY: OK test VIDIOC_S_HW_FREQ_SEEK: OK test VIDIOC_ENUMAUDIO: OK (Not Supported) test VIDIOC_G/S/ENUMINPUT: OK (Not Supported) test VIDIOC_G/S_AUDIO: OK (Not Supported) Inputs: 0 Audio Inputs: 0 Tuners: 1 Output ioctls: test VIDIOC_G/S_MODULATOR: OK (Not Supported) test VIDIOC_G/S_FREQUENCY: OK test VIDIOC_ENUMAUDOUT: OK (Not Supported) test VIDIOC_G/S/ENUMOUTPUT: OK (Not Supported) test VIDIOC_G/S_AUDOUT: OK (Not Supported) Outputs: 0 Audio Outputs: 0 Modulators: 0 Control ioctls: test VIDIOC_QUERYCTRL/MENU: OK test VIDIOC_G/S_CTRL: OK test VIDIOC_G/S/TRY_EXT_CTRLS: OK test VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT: OK test VIDIOC_G/S_JPEGCOMP: OK (Not Supported) Standard Controls: 2 Private Controls: 8 Input/Output configuration ioctls: test VIDIOC_ENUM/G/S/QUERY_STD: OK (Not Supported) test VIDIOC_ENUM/G/S/QUERY_DV_PRESETS: OK (Not Supported) test VIDIOC_ENUM/G/S/QUERY_DV_TIMINGS: OK (Not Supported) test VIDIOC_DV_TIMINGS_CAP: OK (Not Supported) Format ioctls: test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK (Not Supported) test VIDIOC_G/S_PARM: OK (Not Supported) test VIDIOC_G_FBUF: OK (Not Supported) test VIDIOC_G_FMT: OK (Not Supported) test VIDIOC_TRY_FMT: OK (Not Supported) test VIDIOC_S_FMT: OK (Not Supported) test VIDIOC_G_SLICED_VBI_CAP: OK (Not Supported) Codec ioctls: test VIDIOC_(TRY_)ENCODER_CMD: OK (Not Supported) test VIDIOC_G_ENC_INDEX: OK (Not Supported) test VIDIOC_(TRY_)DECODER_CMD: OK (Not Supported) Buffer ioctls: test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK (Not Supported) Total: 38, Succeeded: 38, Failed: 0, Warnings: 0 Andrey Smirnov (6): Add header files and Kbuild plumbing for SI476x MFD core Add the main bulk of core driver for SI476x code Add commands abstraction layer for SI476X MFD Add chip properties handling code for SI476X MFD Add a V4L2 driver for SI476X MFD Add a codec driver for SI476X MFD drivers/media/radio/Kconfig | 17 + drivers/media/radio/Makefile | 1 + drivers/media/radio/radio-si476x.c | 1549 ++++++++++++++++++++++++++++++++++++ drivers/mfd/Kconfig | 14 + drivers/mfd/Makefile | 3 + drivers/mfd/si476x-cmd.c | 1546 +++++++++++++++++++++++++++++++++++ drivers/mfd/si476x-i2c.c | 966 ++++++++++++++++++++++ drivers/mfd/si476x-prop.c | 257 ++++++ include/linux/mfd/si476x-core.h | 539 +++++++++++++ include/media/si476x.h | 427 ++++++++++ sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/si476x.c | 259 ++++++ 13 files changed, 5584 insertions(+) create mode 100644 drivers/media/radio/radio-si476x.c create mode 100644 drivers/mfd/si476x-cmd.c create mode 100644 drivers/mfd/si476x-i2c.c create mode 100644 drivers/mfd/si476x-prop.c create mode 100644 include/linux/mfd/si476x-core.h create mode 100644 include/media/si476x.h create mode 100644 sound/soc/codecs/si476x.c -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
