* MFC r289704:ian2016-01-241-1/+5
| | | | | | | | | | | Fix parsing of I2C addresses properties in fdt data. I2C address is represented in 7-bits format in DT files, but system expect it in 8-bit format. Also, fix two drivers that locally hack around this bug. This includes a direct-commit change to the beaglebone dts data in the 10-stable branch to adjust the i2c slave addresses directly. In -current the equivelent change happened with a switch from homegrown to standard fdt data.

| | | | | | | | | | | Allow i2c bus speed to be configured via hints, FDT data, and sysctl. Implement bus speed setting for OMAP4, AM335x, and imx5/6. Fix the i2c bus speed divisors for TI OMAP4 and AM335x to give the advertised 100, 400, and 1000 KHz speeds. PR: 195009

Give a chance for GPIO devices that implement the device_identify method to attach. r259035: Remove unnecessary includes and an unused softc variable. While here apply two minor style(9) fixes. r259036: Move the GPIOBUS_SET_PINFLAGS(..., ..., pin, GPIO_PIN_OUTPUT) to led(4) control callback function. This makes gpioled(4) works even if the pin is accidentally set to an input. r259037: Fix the pin value reading on AM335x. Because of the inverted logic it was always returning '0' for all the reads, even for the outputs. It is now known to work with gpioiic(4) and gpioled(4). r261842: Add an OFW GPIO compatible bus. This allows the use of the DTS files to describe GPIO bindings in the system. Move the GPIOBUS lock macros to gpiobusvar.h as they are now shared between the OFW and the non OFW versions of GPIO bus. Export gpiobus_print_pins() so it can also be used on the OFW GPIO bus. r261843: Add OFW support to the in tree gpio compatible devices: gpioiic(4) and gpioled(4). Tested on RPi and BBB (using the hardware I2C controller and gpioiic(4) for the I2C tests). It was also verified for regressions on RSPRO (MIPS/ar71xx) used as reference for a non OFW-based system. Update the gpioled(4) and gpioiic(4) man pages with some details and examples about the FDT/OFW support. Some compatibility details pointed out by imp@ will follow in subsequent commits. r261844: Allow the use of OFW I2C bus together with iicbb(4) on OFW-based systems. This change makes ofw_iicbus attach to iicbb(4) controllers in addition to the already supported i2c host bridges (iichb). On iicbb(4) allow the direct access of the OFW parent node by its children, so they can be directly attached to iicbb(4) node on the DTS without the need of describing the i2c bus. r261845: Allow the use of the OFW GPIO bus for ti_gpio and bcm2835_gpio. With this change the gpio children can be described as directly connected to the GPIO controller without the need of describing the OFW GPIO bus itself on the DTS file. With this commit the OFW GPIO bus is fully functional on BBB and RPi. GPIO controllers which want to use the OFW GPIO bus will need similar changes. r261846: Make the gpioled(4) work out of the box on BBB. Add gpioled(4) to BEAGLEBONE kernel and add the description of the four on-board leds of beaglebone-black to its DTS file. r262194: Remove an unnecessary header. r262522: Fix make depend for iicbus. r262559: Inspired by r262522, fix make depend. This fixes the build of gpio modules.

| | | | | | | | | Add a new function (OF_getencprop()) that undoes the transformation applied by encode-int. Specifically, it takes a set of 32-bit cell values and changes them to host byte order. Most non-string instances of OF_getprop() should be using this function, which is a no-op on big-endian platforms. Use the new function all over the place.
