[POWERPC] PS3: Vuart rework

2007-06-28T09:16:40+00:00

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] Remove dev_dbg redefinition in drivers/ps3/vuart.c

2007-04-30T03:03:39+00:00

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 PS3

2007-03-09T23:07:51+00:00

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 read

2007-02-16T03:00:19+00:00

[POWERPC] PS3: Vuart cleanups

2007-02-16T03:00:19+00:00

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 cpu

2007-02-07T03:03:18+00:00

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.
