* mfd: twl6030-irq: Add interrupt mapping table for the twl6032Oleksandr Dmytryshyn2013-08-201-1/+47
| | | | | | | | | | The TWL6032 PMIC has different IRQ status bits meaning. Hence, add interrupt mapping table for the twl6032.

* mfd: twl6030-irq: Convert to use linear irq_domainGrygorii Strashko2013-08-201-50/+69
| | | | | | | | | | | | | | | | | Since the TWL6030 PMIC is used with OMAP4 SoCs only and OMAP4 legacy boot is dropped there are no needs to allocate the range of IRQ descriptors during system boot to support TWL6030 IRQs. Hence, convert it to use linear irq_domain and move IRQ configuration in .map()/.unmap() callbacks of irq_domain. So, IRQ mapping and descriptors allocation will be performed dynamically basing on DT configuration. The error message will be reported in case if unmapped IRQ is received by TWL6030 (virq==0).

* mfd: twl6030-irq: Migrate to IRQ threaded handlerNaga Venkata Srikanth V2013-08-201-100/+50
| | | | | | | | | | | | | | | | | | | | | | | 1) Removed request_irq() and replaced it with request_threaded_irq(). 2) Removed generic_handle_irq() and replaced it with handle_nested_irq(). Handling of these interrupts is nested, as we are handling an interrupt (for e.g rtc, mmc1) when we are still servicing TWL irq. 3) Removed I2C read-retry logic for the case when twl_i2c_read() is failed inside IRQ handler - there is no sense to do that, so just report an error and return. 4) Each nested IRQ is configured with corresponding parent_irq, which need to be retriggered in case if nested IRQ is marked as IRQS_PENDING.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch clears all the events received while powering up DA9055. While powering up DA9055, both power sequencer and gpio events are received. These events remain uncleared after boot up, due to which further event handling also fails. DA9055 has three event registers. The event register bits are set to '1' on receiving an event. The events can be cleared on writing a '1' to the set bit, which would then clear that bit to '0'. After applying this patch we have a clean state after boot up.

This CDB was being freed in sd_done, which results in a kernel crash if the command is retried due to a UNIT ATTENTION. This change moves the code to free the larger CDB into sd_unprep_fn instead, which is invoked after the request is complete. It is no longer necessary to call scsi_print_command separately for this case as the ->cmnd will no longer be NULL in the normal code path. Also removed conditional test for DIF type 2 when freeing the larger CDB because the protection_type could have been changed via sysfs while the command was executing. Signed-off-by: Ewan D.

The race is caused when an I/O termination in the SCU hardware is necessary because of an SSP target timeout condition, and the check of the I/O end state races against the HW-termination-driven end state. The failure of the race meant that no TMF was sent to the device to clean-up the pending I/O.

But a bug report and a closer look at the wrpll table showed that we've supported port clocks up to 300MHz. With the new code to dynamically compute wrpll limits we should have no issues going up to the full 340 MHz range of hdmi 1.4, so let's just use that to fix this regression. That'll allow 4k over hdmi for free! v2: Drop the random hunk that somehow slipped in. v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also patch up the mode filtering. To do so extract the dotclock limits into a little helper function. v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi 1.3), apparently hw is not required to be able to drive the highest dotclocks.

Some digging revealed that it was hanging in combios_parse_mmio_table() while parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card, it becomes obvious that there is no ASIC INIT 3 table in the BIOS. The code is just processing random garbage. No surprise it hangs! Why do I say that there is no ASIC INIT 3 table is the BIOS? This table is found through the MISC INFO table. The MISC INFO table can be found at offset 0x5e in the COMBIOS header. But the header is smaller than that. The COMBIOS header starts at offset 0x126. The standard PCI Data Structure (the bit that starts with 'PCIR') lives at offset 0x180. That means that the COMBIOS header can not be larger than 0x5a bytes and therefore cannot contain a MISC INFO table. I looked at a dozen or so BIOS images, some my own, some downloaded from: <http://www.techpowerup.com/vgabios/index.php?manufacturer=ATI&page=1> It is fairly obvious that the size of the COMBIOS header can be found at offset 0x6 of the header. Not sure if it is a 16-bit number or just an 8-bit number, but that doesn't really matter since the tables seems to be always smaller than 256 bytes. So I think combios_get_table_offset() should check if the requested table is present. This can be done by checking the offset against the size of the header. See the diff below. The diff is against the WIP OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this point. But I don't think this bit of the code changed much since then.
