2009-08-02pcf50633: revise locking for ADCPaul Fertser
Current implementation is prone to races, this patch attempts to remove all but one (in pcf50633_adc_sync_read). The idea is that we need to guard the queue access only on inserting and removing items. If we insert and there're no more items in the queue it means that the last irq already happened and we need to trigger ADC manually. If not, then the next conversion will be triggered by the irq handler upon completion of the previous. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-08-02pcf50633: use a dedicated workqueue for irq processingPaul Fertser
Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

2009-06-13gta02: move debugging messages to the appropriate levelsPaul Fertser
Clean up debugging messages so that we don't see any output with loglevel=4 (default for Qi). This avoids slowing down suspend/resume by slow fb output. Checkpatch barks on this patch but i guess most of that debugging would have to be changed prior to upstream submission anyway. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-04-05Fixed the LCM driver state transition delay and pixel clock issueNicolas Dufresne
Space transition between sleep-in and sleep-out of at least 120 ms as mentionned in the spec. Also, made sure the LCM is moved into sleep state before the pixel clock is turned off. To do so, I've modified glamo-fb to send FB_BLANK_POWERDOWN before turning off the pixel clock. Also fixed various violation of coding style. This patch should reduce the risk of white screen.

2009-02-01debug-add-more-glamo-mem-speed-options.patchAndy Green
People on bug https://docs.openmoko.org/trac/ticket/2217 experiencing problems with default emmory settings on Glamo reported that changing reg 0x200 <- 0xef0 as in 2.6.24 made the problem not reproducible any more. However this changes three bitfields, two are to do with waitstates before sampling read and write cycles off the bus, and the last is to do with which PLL provides the clock to the memory interface unit logic. The old settings has all three of these very conservative, 3 waitstates and using the 50MHz PLL instead of the 90MHz one; the new default setting has all of these at their fastest of 0 wait states and the 90MHz PLL. This patch adds some more granular tests to the same glamo3362.slow_memory= parameter to see if we can find some middle ground. For example the issue may be the waitstates and not the PLL source, in which case even users with the bad Glamo behaviour can have the advantage of the faster PLL / bus bandwidth. 0 90MHz PLL, no wait states (default) 1 50MHz PLL, 3 wait states 2 50MHz PLL, 2 wait states 3 50MHz PLL, 1 wait state 4 50MHz PLL, no wait states 5 90MHz PLL, 3 wait states 6 90MHz PLL, 2 wait states 7 90MHz PLL, 1 wait state Signed-off-by: Andy Green <andy@openmoko.com>

2009-01-15avoid using irq_desc in glamo-mci.cWerner Almesberger
When building the MMC subsystem as modules, drivers/mfd/glamo/glamo-mci.ko cannot access irq_desc, because it isn't exported by kernel/irq/handle.c All the functions that indirectly access irq_desc are inlined, so they cannot be used to avoid having to resolve irq_desc. Fortunately, we can solve the problem locally: we don't really need to access irq_desc anyway. This patch splits glamo_mci_irq into a small wrapper that implements the IRQ handler interface and the main code that doesn't need to know about the semantics of the latter. Then we simply call the main code with the information we already have. Signed-off-by: Werner Almesberger <werner@openmoko.org> Tested-by: Rafael Ignacio Zurita <rizurita@yahoo.com>
