ASoC: topology: Add missing clock gating parameter when parsing hw_configs

2018-08-03T05:48:02Z

[ Upstream commit 933e1c4a667103c4d10ebdc9505a0a6abd8c3fbd ] Clock gating parameter is a part of `dai_fmt`. It is supported by `alsa-lib` when creating a topology binary file, but ignored by kernel when loading this topology file. After applying this commit, the clock gating parameter is not ignored any more. This solution is backwards compatible. The existing behaviour is not broken, because by default the parameter value is 0 and is ignored. snd_soc_tplg_hw_config.clock_gated = 0 => no effect snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT For example, the following config, based on alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported: ~~~~ SectionHWConfig."CodecHWConfig" { id "1" format "I2S" # physical audio format. pm_gate_clocks "true" # clock can be gated } SectionLink."Codec" { # used for binding to the physical link id "0" hw_configs [ "CodecHWConfig" ] default_hw_conf_id "1" } ~~~~ Signed-off-by: Kirill Marinushkin Reviewed-by: Pierre-Louis Bossart Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: Mark Brown Cc: Pan Xiuli Cc: Liam Girdwood Cc: linux-kernel@vger.kernel.org Cc: alsa-devel@alsa-project.org Signed-off-by: Mark Brown Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

regulator: Don't return or expect -errno from of_map_mode()

2018-08-03T05:48:00Z

[ Upstream commit 02f3703934a42417021405ef336fe45add13c3d1 ] In of_get_regulation_constraints() we were taking the result of of_map_mode() (an unsigned int) and assigning it to an int. We were then checking whether this value was -EINVAL. Some implementers of of_map_mode() were returning -EINVAL (even though the return type of their function needed to be unsigned int) because they needed to signal an error back to of_get_regulation_constraints(). In general in the regulator framework the mode is always referred to as an unsigned int. While we could fix this to be a signed int (the highest value we store in there right now is 0x8), it's actually pretty clean to just define the regulator mode 0x0 (the lack of any bits set) as an invalid mode. Let's do that.

serial: core: Make sure compiler barfs for 16-byte earlycon names

2018-08-03T05:48:00Z

[ Upstream commit c1c734cb1f54b062f7e67ffc9656d82f5b412b9c ] As part of bringup I ended up wanting to call an earlycon driver by a name that was exactly 16-bytes big, specifically "qcom_geni_serial". Unfortunately, when I tried this I found that things compiled just fine. They just didn't work. Specifically the compiler felt perfectly justified in initting the ".name" field of "struct earlycon_id" with the full 16-bytes and just skipping the '\0'. Needless to say, that behavior didn't seem ideal, but I guess someone must have allowed it for a reason. One way to fix this is to shorten the name field to 15 bytes and then add an extra byte after that nobody touches. This should always be initted to 0 and we're golden. There are, of course, other ways to fix this too. We could audit all the users of the "name" field and make them stop at both null termination or at 16 bytes. We could also just make the name field much bigger so that we're not likely to run into this. ...but both seem like we'll just hit the bug again.

delayacct: Use raw_spinlocks

2018-08-03T05:47:57Z

[ Upstream commit 02acc80d19edb0d5684c997b2004ad19f9f5236e ] try_to_wake_up() might invoke delayacct_blkio_end() while holding the pi_lock (which is a raw_spinlock_t). delayacct_blkio_end() acquires task_delay_info.lock which is a spinlock_t. This causes a might sleep splat on -RT where non raw spinlocks are converted to 'sleeping' spinlocks. task_delay_info.lock is only held for a short amount of time so it's not a problem latency wise to make convert it to a raw spinlock.

brcmfmac: Add support for bcm43364 wireless chipset

2018-08-03T05:47:53Z

[ Upstream commit 9c4a121e82634aa000a702c98cd6f05b27d6e186 ] Add support for the BCM43364 chipset via an SDIO interface, as used in e.g. the Murata 1FX module. The BCM43364 uses the same firmware as the BCM43430 (which is already included), the only difference is the omission of Bluetooth. However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place triggers the brcmfmac driver to load, and then correctly use the firmware file 'brcmfmac43430-sdio.bin'.
