| | | * clocksource: Deprecate clock string across the SH drivers.Paul Mundt2010-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to get rid of the clock string from platform data entirely, depending on the clkdev-based clock lookup to do the right thing for us instead. This converts all of the SH drivers to request their associated function clocks directly, and if there is no match for that then we fall back on the legacy lookup while warning about it. After all of the outstanding CPUs have been converted to clkdev lookups the clock string will be killed off completely. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is just a simple refactoring patch on top of the early dev_name() support, converting from kstrdup() to kasprintf() as suggested by Kay. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | | * | serial: sh-sci: clkdev updates for MSTP gating.Paul Mundt2010-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes up some of the I/D/F clock ambiguity in the sh-sci driver. The interface clock in most cases just wraps back to the peripheral clock, while the function clock wraps in to the MSTP bits. As the logic was somewhat inverted, this cleans that up, and also enables all CPUs with SCI MSTP bits to match function clocks through clkdev lookup. As a result, this gets rid of the clk string abuse on the sh side, and the clock string will be killed off once the ARM code has had a chance to sync up. This also enables MSTP gating on CPUs like 7786 which had never wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785, and SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | * clocksource: Use dev_name() universally across the SH drivers.Paul Mundt2010-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need to copy in the name from the sh timer config now that dev_name() is available early. We prefer the dev_name() variant for consistent naming. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | | | * driver core: Early dev_name() support.Paul Mundt2010-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently early platform devices suffer from the fact they are unable to use dev_xxx() calls early on due to dev_name() and others being unavailable at the time ->probe() is called. This implements early init_name construction from the matched name/id pair following the semantics of the late device/driver match. As a result, matched IDs (inclusive of requested ones) are preserved when the handoff from the early platform code happens at kobject initialization time. Since we still require kmalloc slabs to be available at this point, using kstrdup() for establishing the init_name works fine. This subsequently needs to be tested from dev_name() prior to the init_name being cleared by the driver core. We don't kfree() since others will already have a handle on the string long before the kobject initialization takes place. This is also needed to permit drivers to use the clock framework early, without having to manually construct their own device IDs from the match id/name pair locally (needed by the early console and timer code on sh and arm).

This is done by moving common structures from sh asm/dmaengine.h to linux/sh_dma.h. DMA registers are also copied from sh asm/dma-register.h to make the code architecture independent. The sh header file asm/dmaengine.h is still kept with the slave id enum. This allows us to keep the old processor specific code as is and slowly move over to slave id enums in per-processor headers.

This patch improves SFF interrupt handler such that 1. Once BMDMA HSM is stopped, the condition is never considered spurious. As there's no way to resume stopped BMDMA HSM, if device status doesn't agree with BMDMA status, the only way out is aborting the command (otherwise, it will just end up timing out). 2. ap->ops->sff_check_status() can be safely called to clear spurious device IRQ as it atomically returns completion status but BMDMA IRQ status can't be cleared in safe way if command is in flight. After a spurious IRQ, call ap->ops->sff_irq_clear() only if the respective device is idle and retry completion if sff_check_status() indicates command completion. Please note that ata_piix uses bmdma_status for sff_irq_check() and #2 won't weaken spurious IRQ handling even with in-flight command because if bmdma_status indicates IRQ pending but device status is not on spurious check, the next IRQ handler invocation will abort the command due to #1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've been getting more and more quirk reports about this. It seems clear at this point that other OSes are not using this for determining whether the integrated panel should be turned on, and it is not reliable for doing so. Better to light up an unintended panel than to not light up the only usable output on the system. Signed-off-by: Eric Anholt <eric@anholt.net> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org>

Which happens on untiled->tiled transition quite often on 4th gen and later because there fencing does not have any special alignment constraints (as opposed to 2nd and 3rd gen on which I've tested the original commit).
