2018-08-21Merge branch 'i2c/for-4.19' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: - the core has now a lockless variant of i2c_smbus_xfer. Some open coded versions of this got removed in drivers. This also enables proper SCCB support in regmap. - locking got a more precise naming. i2c_{un}lock_adapter() had to go, and we know use i2c_lock_bus() consistently with flags like I2C_LOCK_ROOT_ADAPTER and I2C_LOCK_SEGMENT to avoid ambiguity. - the gpio fault injector got a new delicate testcase - the bus recovery procedure got fixed to handle the new testcase correctly - a new quirk flag for controllers not able to handle zero length messages together with driver updates to use it - new drivers: FSI bus attached I2C masters, GENI I2C controller, Owl family S900 - and a good set of driver improvements and bugfixes * 'i2c/for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (77 commits) i2c: rcar: implement STOP and REP_START according to docs i2c: rcar: refactor private flags i2c: core: ACPI: Make acpi_gsb_i2c_read_bytes() check i2c_transfer return value i2c: core: ACPI: Properly set status byte to 0 for multi-byte writes dt-bindings: i2c: rcar: Add r8a774a1 support dt-bindings: i2c: sh_mobile: Add r8a774a1 support i2c: imx: Simplify stopped state tracking i2c: imx: Fix race condition in dma read i2c: pasemi: remove hardcoded bus numbers on smbus i2c: designware: Add SPDX license tag i2c: designware: Convert to use struct i2c_timings i2c: core: Parse SDA hold time from firmware i2c: designware-pcidrv: Mark expected switch fall-through i2c: amd8111: Mark expected switch fall-through i2c: sh_mobile: use core to detect 'no zero length read' quirk i2c: xlr: use core to detect 'no zero length' quirk i2c: rcar: use core to detect 'no zero length' quirk i2c: stu300: use core to detect 'no zero length' quirk i2c: pmcmsp: use core to detect 'no zero length' quirk i2c: mxs: use core to detect 'no zero length' quirk ...

2018-08-08media: cleanup fall-through commentsMauro Carvalho Chehab
As Ian pointed out, adding a '-' to the fallthrough seems to meet the regex requirements at level 3 of the warning, at least when the comment fits into a single line. So, replace by a single line the comments that were broken into multiple lines just to make gcc -Wimplicit-fallthrough=3 happy.

The maximum and minimum frequency of MN88443x comes from ISDB-S and ISDB-T so frequency range is the following: - ISDB-S (BS/CS110 IF frequency, Local freq 10.678GHz) - Min: BS-1: 1032MHz - Max: ND24: 2070MHz - ISDB-T - Min: ch13: 470MHz - Max: ch62: 770MHz Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

2018-08-02media: dvb: represent min/max/step/tolerance freqs in HzMauro Carvalho Chehab
Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

Add a tsspeed config option to struct stv0910_cfg which can be used by users of the driver to set the (parallel) TS speed (higher speeds enable support for higher bitrate transponders). If tsspeed isn't set in the config, it'll default to a sane value. This commit also updates the two consumers of the stv0910 driver (ngene and ddbridge) to have a default tsspeed in their stv0910_cfg templates.

2018-05-04media: lgdt330x: add block error counts via DVBv5Mauro Carvalho Chehab
Show the UCB error counts via DVBv5. Please notice that there's no scale indication at the driver. As we don't have the datasheet, let's assume that it is receiving data at a rate of 10.000 packets per second. Ideally, this should be read or estimated. In order to avoid flooding I2C bus with data, the maximum polling rate for those stats was set to 1 second.

In preparation to implement DVBv5 stats on this driver, move the *read_status functions to happen after SNR and signal strength routines. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-05-04media: lgdt330x: constify several register init arraysMauro Carvalho Chehab
There are several register init arrays there that can be constified.

Simplify a few ifs there. While here, add debug messages for the 8-vsb and qam log status flags. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-05-04media: lgdt330x: convert it to the new I2C binding wayMauro Carvalho Chehab
Convert the driver to allow its usage with the new I2C binding way. Please notice that this patch doesn't convert the callers to bind to it using the new way. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-05-04media: lgdt330x: print info when device gets probedMauro Carvalho Chehab
It is useful to know if the driver load succeded. So, add a printk info there. While here, improve the .init debug printed message. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

2018-05-04media: dvb-frontends/stv0910: fix CNR reporting in read_snr()Daniel Scheller
The CNR value determined in read_snr() is reported via the wrong variable. It uses FE_SCALE_DECIBEL, which implies the value to be reported in svalue instead of uvalue. Fix this accordingly.
