* [POWERPC] PS3: Vuart reworkGeoff Levand2007-06-281-48/+23
| | | | | | | | | | | | | | | | | | | | | PS3 vuart updates to reflect the new PS3 unified device support. - Move vuart devices to the PS3 system bus. - Replace use of ps3_vuart_port_device with ps3_system_bus_device. - Make the PS3 vuart bus driver a loadable module. - Add remove() and shutdown() routines. - Move ps3_vuart_work into ps3_vuart_port_priv.tx_list. - Remove redundant spinlock ps3_vuart_work.lock. - No longer free ps3_vuart_port_device.priv on shutdown. - Cleanup Kconfig defs. - Export symbols needed for modular port drivers. - Arrange to use port numbers found in repository. - Fix bugs in ps3_vuart_read_async() and polled reading - Cleanup handling of shared interrupt with ps3_vuart_bus_interrupt_get() and ps3_vuart_bus_interrupt_put() - Add more comments to vuart.c.

* [POWERPC] PS3: Vuart add async readGeoff Levand2007-02-161-4/+25
| | | | | | | | Add asynchronous read support to the PS3 vuart driver. This is needed to support the PS3 system manager driver. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] PS3: Vuart cleanupsGeoff Levand2007-02-161-0/+30
| | | | | | | | | | | | | | | Cleanups for the PS3 vuart driver. - Hide driver private data from external interface with new structure ps3_vuart_port_priv. - Fix masking bug in ps3_vuart_get_interrupt_status(). - Add new helper routine ps3_vuart_clear_rx_bytes() to flush rx buffer. - Add new variable probe_mutex to serialize probe and destroy routines. - Rename some symbols. - Add platform check in ps3_vuart_bus_init().

* [POWERPC] ps3: Add vuart supportGeoff Levand2006-12-111-0/+94
Adds support for the PS3 virtual UART (vuart). The vuart provides a bi-directional byte stream data link between logical partitions. This is needed for the ps3 graphics driver and the ps3 power control support to be able to communicate with the lv1 policy module.
