Merge tag 'module-implicit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

2015-07-02T17:25:22Z

Pull implicit module.h fixes from Paul Gortmaker: "Fix up implicit users that will break later. The files changed here are simply modular source files that are implicitly relying on being present. We fix them up now, so that we can decouple some of the module related init code from the core init code in the future. The addition of the module.h include to several files here is also a no-op from a code generation point of view, else there would already be compile issues with these files today. There may be lots more implicit includes of in tree, but these are the ones that extensive build test coverage has shown that must be fixed in order to avoid build breakage fallout for the pending module.h <---> init.h code relocation we desire to complete" * tag 'module-implicit-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: frv: add module.h to mb93090-mb00/flash.c to avoid compile fail drivers/cpufreq: include for modular exynos-cpufreq.c code drivers/staging: include for modular android tegra_ion code crypto/asymmetric_keys: pkcs7_key_type needs module.h sh: mach-highlander/psw.c is tristate and should use module.h drivers/regulator: include for modular max77802 code drivers/pcmcia: include for modular xxs1500_ss code drivers/hsi: include for modular omap_ssi code drivers/gpu: include for modular rockchip code drivers/gpio: include for modular crystalcove code drivers/clk: include for clk-max77xxx modular code

HSI: nokia-modem: use flags argument of devm_gpiod_get to set direction

2015-06-23T00:40:03Z

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Use this to simplify the driver. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.

HSI: nokia-modem: Reduce missing driver message to debug level

2015-06-23T00:40:03Z

Reduce message priority from dev_err to dev_dbg for missing cmt-speech or ssi-protocol drivers, since they will be probed again and it may result in spamming the boot log. Reported-by: Aaro Koskinen Signed-off-by: Sebastian Reichel

HSI: cmt_speech: fix timestamp interface

2015-06-23T00:40:03Z

The user interface for timestamps in the new cmt_speech driver is broken in multiple ways: - The layout is incompatible between 32-bit and 64-bit user space, because of the size differences in 'struct timespec'. This means that the driver can not work when used with 32-bit user space on a 64-bit kernel. - As there are plans to change 32-bit user space to use a 64-bit time_t type in the future, it will also be incompatible with new 32-bit user space. - It is using ktime_get_ts under it's deprecated alias (do_posix_clock_monotonic_gettime). To keep support for the user space tools written for this driver (which have lived many years out-of-tree), the interface has been hardened to unsigned 32-bit values.

drivers/hsi: include for modular omap_ssi code

2015-06-16T18:12:25Z

These files are built off of a tristate Kconfig option and also contain modular function calls so they should explicitly include module.h to avoid compile breakage during header shuffles done in the future. We change the one header file wich gives us coverage on both files: drivers/hsi/controllers/omap_ssi.c drivers/hsi/controllers/omap_ssi_port.c Cc: Sebastian Reichel Signed-off-by: Paul Gortmaker

HSI: cmt_speech: fix error return code

Return a negative error code on failure. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ identifier ret; expression e1,e2; @@ ( if (\(ret < 0\|ret != 0\)) { ... return ret; } | ret = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // Signed-off-by: Julia Lawall Signed-off-by: Sebastian Reichel

HSI: cmt_speech: Add cmt-speech driver

2015-03-31T20:14:04Z

Introduces the cmt-speech driver, which implements a character device interface for transferring speech data frames over HSI/SSI. The driver is used to exchange voice/speech data between the Nokia N900/N950/N9's modem and its cpu. Signed-off-by: Kai Vehmanen Signed-off-by: Carlos Chinea Signed-off-by: Joni Lapilainen Since the original driver has been written for 2.6.28 some build fixes and general cleanups have been added by me: * fix build for 4.0 kernel * replace GFP_ATOMIC with GFP_KERNEL in cs_alloc_cmds() * add sanity check for CS_SET_WAKELINE ioctl * cleanup driver initialisation * rename driver to cmt-speech to be consistent with ssi-protocol driver * move cs-protocol.h to include/uapi/linux/hsi, since it describes a userspace API * replace hardcoded channels numbers with values provided via the HSI framework (e.g. coming from DT) Acked-by: Aaro Koskinen Tested-by: Pavel Machek Signed-off-by: Sebastian Reichel
