Simplify this function so that it no longer depends on malloc() to execute. Rename device_delete_all_children() into device_delete_children(). Identify a few other places where it makes sense to use device_delete_children(). MFC r226173, r227843, r227848 and r227908: 2011-12-31T14:12:12Z Hans Petter Selasky hselasky@FreeBSD.org 2011-12-31T14:12:12Z urn:sha1:0105e7b57ec82d3d157edb9f4322f29f05d54f6e Use DEVMETHOD_END to mark end of device methods. Remove superfluous device methods. Add some missing __FBSBID() macros. Add a GPIO driver for the Gateworks Cambria platform. 2010-11-11T20:18:33Z Andrew Thompson thompsa@FreeBSD.org 2010-11-11T20:18:33Z urn:sha1:54873b4cd6c691e7135ac9647afc5d54875d8a2c The external gpio pins are connected to a PLD on the i2c bus, unfortunatley this device does not conform by failing to send an ack after each byte written. The iicbb driver will abort the transfer when the address is not ack'd and it would introduce a lot of churn to be able to pass a flag down to iicbb_start/iicbb_write. Instead we do bad things by grabbing the iicbus but then doing our own bit banging. Set the pin to output on attach, we can't assume it already is. 2010-11-08T03:08:01Z Andrew Thompson thompsa@FreeBSD.org 2010-11-08T03:08:01Z urn:sha1:cac6df751b207debda23d8f07e9a2e2e1d72dc2d Reviewed by: gonzo Fix legal staff in GPIO sources: 2010-09-29T20:53:33Z Oleksandr Tymoshenko gonzo@FreeBSD.org 2010-09-29T20:53:33Z urn:sha1:5f958b853422db235a67b8b8635d11e49ae67402 - license clause now contains "AUTHOR AND CONTRIBUTORS" instead of just "AUTHOR" - Add license/copyright to gpioc.c Spotted by: Edward Tomasz Napierala, Andrew Turner Initial GPIO bus support.
