* [POWERPC] PS3: Vuart reworkGeoff Levand2007-06-281-326/+487
| | | | | | | | | | | | | | | | | | | | | 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: Use __maybe_unusedGeoff Levand2007-06-281-2/+2

* [POWERPC] Remove dev_dbg redefinition in drivers/ps3/vuart.cPaul Mackerras2007-04-301-8/+0
| | | | | | | | | Commit 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 changed the definition of dev_dbg in the !DEBUG case from being a #define to being a static inline. There was code in drivers/ps3/vuart.c to do exactly that, which fails to compile now. This fixes it by removing the redefinition, as the redefinition is now superfluous.

* [POWERPC] ps3: always make sure were running on a PS3Geert Uytterhoeven2007-03-101-1/+1
| | | | | | | | | | | Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that we are actually running on a PS3 (pointed out by Arnd). Correct existing checks in other subsystems/drivers to return -ENODEV instead of zero.

* [POWERPC] PS3: Vuart add async readGeoff Levand2007-02-161-0/+53
| | | | | | | | 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 Levand2007-02-161-132/+215
| | | | | | | | | | | | | | | 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: bind interrupt to cpuGeoff Levand2007-02-071-2/+2
| | | | | | | | | | | | Change the PS3 irq allocation routines to take an argument indicating which cpu (processor thread) the interrupt should be serviced on. The current system configuration favors device interrupts that are serviced on cpu0, so that is used as the default.

* [POWERPC] ps3: Add vuart supportGeoff Levand2006-12-111-0/+965
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.
