r355598: Do not attach children of owc_gpiobus until interrupts are working. The children of the bus need to do IO on the bus to probe for hardware presence. Doing IO means timing the bus states using sbinuptime(), and that requires working timecounters, which are not initialized until after device attachment has completed. PR: 242526 r355727 (by imp): Create new wrapper function: bus_delayed_attach_children() Delay the attachment of children, when requested, until after interrutps are running. This is often needed to allow children to run transactions on i2c or spi busses. It's a common enough idiom that it will be useful to have its own wrapper. Reviewed by: ian Differential Revision: https://reviews.freebsd.org/D21465 r355735 (by imp): Be consistent about checking return value from bus_delayed_attach_children. Most places checked, but a couple last minute changes didn't. Make them all use the return value. Noticed by: rpokala@ r355858: Update owc_gpiobus (one-wire over gpio) to the modern gpio_pin interface. It used to be required that a device be a child of gpiobus(4) to manipulate gpio pins. That requirement didn't work well for FDT-based systems with many cross-hierarchy users of gpio, so a more modern framework was created that removed the old hierarchy requirement. These changes adapt the owc_gpiobus driver to use the newer gpio_pin_* functions to acquire, release, and manipulate gpio pins. This allows a single driver to work for both hinted-attachment and fdt-based systems, and removes the requirement that any one-wire fdt nodes must appear at the root of the devicetree.

Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere().

2016-02-27T03:38:01Z

Most calls to bus_alloc_resource() use "anywhere" as the range, with a given count. Migrate these to use the new bus_alloc_resource_anywhere() API. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D5370
