* Allow i2c bus speed to be configured via hints, FDT data, and sysctl.Ian Lepore2014-11-181-12/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current support for controlling i2c bus speed is an inconsistant mess. There are 4 symbolic speed values defined, UNKNOWN, SLOW, FAST, FASTEST. It seems to be universally assumed that SLOW means the standard 100KHz rate from the original spec. Nothing ever calls iicbus_reset() with a speed of FAST, although some drivers would treat it as the 400KHz standard speed. Mostly iicbus_reset() is called with the speed set to UNKNOWN or FASTEST, and there's really no telling what any individual driver will do with those. The speed of an i2c bus is limited by the speed of the slowest device on the bus. This means that generally the bus speed needs to be configured based on the board/system and the components within it. Historically for i2c we've configured with device hints. Newer systems use FDT data and it documents a clock-frequency property for i2c busses. Hobbyists and developers are likely to want on the fly changes. These changes provide all 3 methods, but do not require any existing drivers to change to use the new facilities. This adds an iicbus method, iicbus_get_frequency(dev, speed) that gets the frequency for the requested symbolic speed. If the symbolic speed is SLOW or if there is no speed configured for the bus, the returned value is 100KHz, always. Otherwise, if bus speed is configured by hints, fdt, tunable, or sysctl, that speed is returned. It also adds a helper function, iicbus_init_frequency() that any bus driver subclassed from iicbus can initialize the frequency from some other source of info. Initial driver implementations are provided for Freescale and TI. Differential Revision: https://reviews.freebsd.org/D1174 PR: 195009 Notes: svn path=/head/; revision=274641

* Bugfixes for the imx5/imx6 iomux fdt_pinctrl driver.Ian Lepore2014-11-121-3/+21
| | | | | | | | | | | | | | | | I originally overlooked a couple flag bits defined in the fdt binding docs. One flag suppresses the pad configuration (pullup/pulldown/etc). The other one requires that the SION (set input on) flag be set in the mux register. Also, it appears from the data involved that if the input register address in the config tuple is zero, there is no input configuration. The old code was writing to register zero, which contains a collection of misc control bits (having nothing to do with input configuration) that probably shouldn't get overwritten arbitrarily. The bindings doc doesn't explictly mention this. Notes: svn path=/head/; revision=274412

| | | | | | | | | | | | unit 0. It seems that this 'simplification' was copied to all GPIO drivers in tree. This fix a bug where a GPIO controller could fail to attach its children (gpioc and gpiobus) if another GPIO driver attach first. Notes: svn path=/head/; revision=273799
* Install a temporary workaround to avoid problems in fdt data with linux'sIan Lepore2014-10-231-1/+35
| | | | | | | | | | | | | workaround for an imx6 chip erratum. Linux works around the bug with changes in fdt data that we can't currently handle, so to enable running with standard vendor-supplied fdt data, this watches for an attempt to map the gpio1_6 interrupt and remaps it back to the standard ethernet interrupt. This can be undone when the intrng project is completed and our gpio drivers can also be interrupt controllers. Notes: svn path=/head/; revision=273561

| | | | | | | | | timecounter resolution is available, so ask for a 1 GHz frequency. It won't actually get one that fast, but that'll get the fastest available clock and use a divisor of 1 (probably 132 or 66mhz on current hardware). Notes: svn path=/head/; revision=273352

This allows the anatop driver to outbid the generic simplebus driver (which the FDT data describes as compatible). Some day when we handle power regulators, this driver may actually become a functional simplebus and attach the regulators as children, as described in the FDT data.

* Extend the meaning of the CTLFLAG_TUN flag to automatically check ifHans Petter Selasky2014-06-271-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.
