2016-06-09[media] af9035: fix for MXL5007T devices with I2C read issuesAlessandro Radicati2-0/+22
The MXL5007T tuner will lock-up on some devices after an I2C read transaction. This patch works around this issue by inhibiting such operations and emulating a 0x00 response. The workaround is only applied to USB devices known to exhibit this flaw.

2016-05-28Merge branch 'hash' of git://ftp.sciencehorizons.net/linuxLinus Torvalds1-0/+2
Pull string hash improvements from George Spelvin: "This series does several related things: - Makes the dcache hash (fs/namei.c) useful for general kernel use. (Thanks to Bruce for noticing the zero-length corner case) - Converts the string hashes in <linux/sunrpc/svcauth.h> to use the above. - Avoids 64-bit multiplies in hash_64() on 32-bit platforms. Two 32-bit multiplies will do well enough. - Rids the world of the bad hash multipliers in hash_32. This finishes the job started in commit 689de1d6ca95 ("Minimal fix-up of bad hashing behavior of hash_64()") The vast majority of Linux architectures have hardware support for 32x32-bit multiply and so derive no benefit from "simplified" multipliers. The few processors that do not (68000, h8/300 and some models of Microblaze) have arch-specific implementations added. Those patches are last in the series. - Overhauls the dcache hash mixing. The patch in commit 0fed3ac866ea ("namei: Improve hash mixing if CONFIG_DCACHE_WORD_ACCESS") was an off-the-cuff suggestion. Replaced with a much more careful design that's simultaneously faster and better. (My own invention, as there was noting suitable in the literature I could find. Comments welcome!) - Modify the hash_name() loop to skip the initial HASH_MIX(). This would let us salt the hash if we ever wanted to. - Sort out partial_name_hash(). The hash function is declared as using a long state, even though it's truncated to 32 bits at the end and the extra internal state contributes nothing to the result. And some callers do odd things: - fs/hfs/string.c only allocates 32 bits of state - fs/hfsplus/unicode.c uses it to hash 16-bit unicode symbols not bytes - Modify bytemask_from_count to handle inputs of 1..sizeof(long) rather than 0..sizeof(long)-1. This would simplify users other than full_name_hash" Special thanks to Bruce Fields for testing and finding bugs in v1. (I learned some humbling lessons about "obviously correct" code.) On the arch-specific front, the m68k assembly has been tested in a standalone test harness, I've been in contact with the Microblaze maintainers who mostly don't care, as the hardware multiplier is never omitted in real-world applications, and I haven't heard anything from the H8/300 world" * 'hash' of git://ftp.sciencehorizons.net/linux: h8300: Add <asm/hash.h> microblaze: Add <asm/hash.h> m68k: Add <asm/hash.h> <linux/hash.h>: Add support for architecture-specific functions fs/namei.c: Improve dcache hash function Eliminate bad hash multipliers from hash_32() and hash_64() Change hash_64() return value to 32 bits <linux/sunrpc/svcauth.h>: Define hash_str() in terms of hashlen_string() fs/namei.c: Add hashlen_string() function Pull out string hash to <linux/stringhash.h>
2016-05-28Eliminate bad hash multipliers from hash_32() and hash_64()George Spelvin1-0/+2
The "simplified" prime multipliers made very bad hash functions, so get rid of them. This completes the work of 689de1d6ca. To avoid the inefficiency which was the motivation for the "simplified" multipliers, hash_64() on 32-bit systems is changed to use a different algorithm. It makes two calls to hash_32() instead. drivers/media/usb/dvb-usb-v2/af9015.c uses the old GOLDEN_RATIO_PRIME_32 for some horrible reason, so it inherits a copy of the old definition.

2016-05-04[media] rtl2832: change the i2c gate to be mux-lockedPeter Rosin1-4/+1
The root i2c adapter lock is then no longer held by the i2c mux during accesses behind the i2c gate, and such accesses need to take that lock just like any other ordinary i2c accesses do. So, declare the i2c gate mux-locked, and zap the regmap overrides that makes the i2c accesses unlocked and use plain old regmap accesses. This also removes the need for the regmap wrappers used by rtl2832_sdr, so deconvolute the code further and provide the regmap handle directly instead of the wrapper functions.

2016-02-04[media] dvb_frontend: pass the props cache to get_frontend() as argMauro Carvalho Chehab1-2/+2
Instead of using the DTV properties cache directly, pass the get frontend data as an argument. For now, everything should remain the same, but the next patch will prevent get_frontend to affect the global cache. This is needed because several drivers don't care enough to only change the properties if locked. Due to that, calling G_PROPERTY before locking on those drivers will make them to never lock. Ok, those drivers are crap and should never be merged like that, but the core should not rely that the drivers would be doing the right thing.

2016-02-01[media] rtl28xxu: retry failed i2c messagesAntti Palosaari1-0/+8
Sometimes i2c transfer fails. That happens especially when large amount of data is written sequentially eg. firmware download. Problem arises with both integrated rtl2832 demod and external mn88472 demod, which is clear indicator it is busy i2c bus issue. Use i2c core retry logic in order fix the issue by repeating failed message. Another solution which also works is to add ~100us delay between i2c messages - but repeating sounds more elegant and does not cause any extra delay for success cases.

2016-01-11[media] media-device: split media initialization and registrationJavier Martinez Canillas1-11/+12
The media device node is registered and so made visible to user-space before entities are registered and links created which means that the media graph obtained by user-space could be only partially enumerated if that happens too early before all the graph has been created. To avoid this race condition, split the media init and registration in separate functions and only register the media device node when all the pending subdevices have been registered, either explicitly by the driver or asynchronously using v4l2_async_register_subdev(). The media_device_register() had a check for drivers not filling dev and model fields but all drivers in mainline set them and not doing it will be a driver bug so change the function return to void and add a BUG_ON() for dev being NULL instead. Also, add a media_device_cleanup() function that will destroy the graph_mutex that is initialized in media_device_init().

2015-06-10[media] TS2020: Calculate tuner gain correctlyDavid Howells1-0/+2
The TS2020 and TS2022 tuners take an input from the demodulator indicating the AGC setting on that component that is then used to influence the tuner's own gain. This should be taken into account when calculating the gain and signal strength. Further, the existing TS2020 driver miscalculates the signal strength as the result of its calculations can exceed the storage capacity of the 16-bit word used to return it to userspace. To this end: (1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that the tuner can call to get the AGC PWM value from the demodulator. (2) Modify the TS2020 driver to calculate the gain according to Montage's specification with the adjustment that we produce a negative value and scale it to 0.001dB units (which is what the DVBv5 API will require): (a) Callback to the demodulator to retrieve the AGC PWM value and then turn that into Vagc for incorporation in the calculations. If the callback is unset, assume a Vagc of 0. (b) Calculate the tuner gain from a combination of Vagc and the tuner's RF gain and baseband gain settings. (3) Turn this into a percentage signal strength as per Montage's specification for return to userspace with the DVBv3 API. (4) Provide a function in the M88DS3103 demodulator driver that can be used to get the AGC PWM value on behalf of the tuner. (5) The ts2020_config.get_agc_pwm function should be set by the code that stitches together the drivers for each card. For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022, set the get_agc_pwm function to point to m88ds3103_get_agc_pwm. I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022. Thanks to Montage for providing access to information about the workings of these parts.

2015-06-09[media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab5-19/+20
The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.
