由 Simon Arlott 提交于
The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt controller, and pinmux/control device. Original driver by Simon Arlott. Rewrite including GPIO chip device by Chris Boot. Upstreaming changes by Stephen Warren: * Wrote DT binding documentation. * Changed brcm,function to an integer to more directly match the datasheet, and to match brcm,pins being an integer. * Implemented pull-up/down pin config. * Removed read-only DT property and related code. The restriction this implemented are driven by the board, not the GPIO HW block, so don't really make sense of a HW block binding, were in general incomplete (since they could only know about the few pins hard-coded into the Raspberry Pi B board design and not the uncommitted GPIOS), and are better represented simply by not writing incorrect data into pin configuration nodes. * Don't set GPIO_IN function select in gpio_request_enable() to avoid glitches; defer this to gpio_set_direction(). Consequently, removed empty bcm2835_pmx_gpio_request_enable(). * Simplified enabled_irq_map[]; make it explicitly 1 entry per bank. * Lifted use of enabled_irq_map[] outside the per-interrupt loop in IRQ handler, thus fixing an issue where the code was indexing into enabled_irq_map[] by intra-bank GPIO ID, not global GPIO ID. * Removed locking in IRQ handler, since all other code uses spin_lock_irqsave() and so guarantees it doesn't run concurrently with the handler. * Moved duplicated BUILD_BUG_ON()s into probe(). Also check size of bcm2835_gpio_pins[]. * Remove range-checking from bcm2835_pctl_get_groups_count() since we've decided to trust the pinctrl core. * Made bcm2835_pmx_gpio_disable_free() call bcm2835_pinctrl_fsel_set() directly for simplicity. * Fixed body of dt_free_map() to match latest dt_node_to_map(). * Removed GPIO ownership check from bcm2835_pmx_enable() since the pinctrl core owns doing this. * Made irq_chip and pinctrl_gpio_range .name == MODULE_NAME so it's more descriptive. * Simplified remove(); removed call to non-existent pinctrl_remove_gpio_range(), remove early return on error. * Don't force gpiochip's base to 0. Set gpio_range.base to gpiochip's base GPIO number. * Error-handling cleanups in probe(). * Switched to module_platform_driver() rather than open-coding. * Made pin, group, and function names lower-case. * s/broadcom/brcm/ in DT property names. * s/2708/2835/. * Fixed a couple minor checkpatch warnings, and other minor cleanup.

由 Stephen Warren 提交于
When the bindings for the TPS6586x regulator were being proposed, I asserted that DT node naming rules for bus child nodes should also be applied to nodes inside the TPS6586x regulator node itself. In other words, that each node providing regulator init data should be named after the type of object it represented ("regulator") and hence that some other property was required to indicate which regulator the node described ("regulator-compatible"). In turn this led to multiple nodes having the same name, thus requiring node names to use a unit address to make them unique, thus requiring reg properties within the nodes and However, subsequent discussion indicates that the rules I was asserting only applies to standardized bus nodes, and within a device's own node, the binding can basically do anything sane that it wants. Hence, this change deprecates the register-compatible property, and instead uses node names to replace this functionality. This greatly simplifies the device tree content, making them smaller and more legible. The code is changed such that old device trees continue to work.

Even with devicetree support, we needed platform data to provide some data, leading to mixed device tree and platform data.
