2009-01-16powerpc/ps3: clear_bit()/set_bit() operate on unsigned longsStephen Rothwell
This fixes these compiler warning: arch/powerpc/platforms/ps3/interrupt.c:109: warning: passing argument 2 of 'clear_bit' from incompatible pointer type arch/powerpc/platforms/ps3/interrupt.c:130: warning: passing argument 2 of 'set_bit' from incompatible pointer type Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-01-16powerpc/ps3: The lv1_ routines have u64 parametersStephen Rothwell
We just fix up the reference parameters as the others are dealt with by arithmetic promotion rules and don't cause warnings. This removes warnings like this: arch/powerpc/platforms/ps3/interrupt.c:327: warning: passing argument 1 of 'lv1_construct_event_receive_port' from incompatible pointer type Also, these: drivers/ps3/ps3-vuart.c:462: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type drivers/ps3/ps3-vuart.c:592: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2008-05-02[POWERPC] PS3: Make ps3_virq_setup and ps3_virq_destroy staticGeert Uytterhoeven
The routines ps3_virq_setup() and ps3_virq_destroy() are used in only one file, so make them static. Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2007-09-14[POWERPC] Invert null match behaviour for irq_hostsMichael Ellerman
Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback. This in itself isn't very useful, but will allow us to provide a default match implementation in a subsequent patch.

2007-09-14[POWERPC] Add an optional device_node pointer to the irq_hostMichael Ellerman
The majority of irq_host implementations (3 out of 4) are associated with a device_node, and need to stash it somewhere. Rather than having it somewhere different for each host, add an optional device_node pointer to the irq_host structure.

2007-06-28[POWERPC] PS3: Vuart reworkGeoff Levand
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.

2007-06-28[POWERPC] PS3: System-bus reworkGeoff Levand
Rework the PS3 system bus to unify device support. - DMA region sizes must be a power of two - storage bus DMA updates: - Small fixes for the PS3 DMA core: o fix alignment bug o kill superfluous test o indentation o spelling o export ps3_dma_region_{create,free}() - ps3_dma_region_init(): o Add `addr' and `len' parameters, so you can create a DMA region that does not cover all memory (use `NULL' and `0' to cover all memory). This is needed because there are not sufficient IOMMU resources to have all DMA regions cover all memory. o Uninline - Added remove and shutdown routines to all drivers. - Added loadable module support to all drivers. - Added HV calls for iopte management (needed by sound driver).
