2009-04-21glamo_fb: make Xglamo workaround conditionalNelson Castillo
Distributions that use Xorg will not need the workaround at all and now they can disable it. Updated configurations to enable it by default. Signed-off-by: Nelson Castillo <arhuaco@freaks-unidos.net>

2009-04-20Make Xglamo workaround opt-out. Fixes #2255.Nelson Castillo
To disable the workaround at run-time run: echo 0 > /sys/class/i2c-adapter/i2c-0/0-0073/pcf50633-regltr.9/glamo3362.0/glamo-fb.0/xglamo_hack I guess I should add a compile option now to completely disable the workaround but let's call this an enhancement and let's close the bug now. By default the workaround is enabled. Signed-off-by: Nelson Castillo <arhuaco@freaks-unidos.net> Reported-by: Timo Juhani Lindfors <timo.lindfors@iki.fi>

2009-04-19Revert "Fixed the LCM driver state transition delay and pixel clock issue"Nelson Castillo
This reverts commit bd4b7e8e84ab43a13a4620b001d52d373c2122b3 which brought WSOD back for some devices. It was reported that the problem does not happen with Qi and it seem it is good news. See: https://docs.openmoko.org/trac/ticket/2274 Conflicts: drivers/video/display/jbt6k74.c
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.

2009-03-26Add to Glamo-DRM initialisation routineThomas White
This adds some MMIO initialisation stuff to glamo-drm.c. Signed-off-by: Thomas White <taw@bitwiz.org.uk>
2009-03-26Fix MMC buffer locationsThomas White
This fixes the MMC buffer locations in glamo-mci.c, which were broken by the reorganisation of Glamo's memory. Signed-off-by: Thomas White <taw@bitwiz.org.uk>
2009-03-26Pass core Glamo device to DRM moduleThomas White
This adds a missing statement to let glamo-drm.c know the core Glamo handle, so it can manipulate registers such as the 2D and 3D clocks. Signed-off-by: Thomas White <taw@bitwiz.org.uk>
2009-03-26Tidy up Glamo memory map declarationsThomas White
This just cosmetically tidies up the declarations in glamo-core.h. We have to be very clear about what lives where in the memory. Signed-off-by: Thomas White <taw@bitwiz.org.uk>
2009-03-26Remove Glamo's 2D, 3D, JPEG and MPEG devicesThomas White
This patch removes the platform devices corresponding to Glamo's 2D, 3D, JPEG and MPEG engines. These will later be handled via DRM. Signed-off-by: Thomas White <taw@bitwiz.org.uk>

2009-02-20fix-glamo-mci-move-stop-out-of-isr.patchAndy Green
This patch moves the bulk transfer action outside of interrupt context, along with the STOP transmission action for multiblock transfers. It's prompted by https://docs.openmoko.org/trac/ticket/2180 But it can impact throughput to SD card, so it's for testing currently. Signed-off-by: Andy Green <andy@openmoko.com>

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>
