* imx233: fix sd windowed driveAmaury Pouly2013-01-15
| | | | | | | | | | The SD driver doesn't initialised drives at the beginning but upon request to handle removable drives. Since means that the init should call init_drive() and not init_sd_card() otherwise the check for WINDOW flag is bypasses. This breaks the zenxfi3 bootloader and has been overlooked for some time.

* imx233: rework frequency scalingAmaury Pouly2013-01-13
| | | | | | | | | | | Move to a table based approach (scales better) and distinguish between upward changes (increase frequency) and downward changes (decrease frequency). This provides a better ordering of operations and in particular it allows to avoid changing the regulator while running at low speed since it takes a long time ! This should result in a much smoother scaling. Change-Id: Iad7e5b61277e215f31c07877fbbad07ddde1171f

* fuze+: correctly handle settings (flip and invert) accross enableAmaury Pouly2013-01-12
| | | | | | | | | The flip and invert settings can potentially be reset to their value accross a disable/enable cycle, so save the value of the impacted registers and apply it after each enable. Also avoid poking registers when the lcd is not on. Change-Id: Ica98f166c060aade7eb205f5628b58aae692024f
* imx233: enable underflow recovery in lcdif (needed for freq scale)Amaury Pouly2013-01-12
| | | | | | | | | | | | | | When chaging the cpu and memory frequency we need to disable the external memory interface (EMI) for a small time. This can underflow the dma and cause some breakage. Hopefully the SSP controller handles this gracefully by stopping the clock and the I2C probably handles this naturally because the clock can be streched anyway. However the LCDIF has a special setting for this which needs to be enable, otherwise it will send garbage to the LCD. No other block is known to suffer from this currently but this issue might have more unexpected consequences. Change-Id: Ide154cad87929f2bf6cc419ac1d2ff33e30eec66

* imx233: modify arm cache timings on frequency switchAmaury Pouly2013-01-10
| | | | | | | | | The manual recommands to tweak the arm cache settings on frequency changes. The meaning of these values is undocumented but 0 seems to be a safe value for all frequencies whereas 3 seems to be valid only for low frequencies (<=64MHz ?)

* imx233: implement emi frequency scaling (disabled by default)Amaury Pouly2013-01-10
| | | | | | | | | | | | | | | | | | | | | | | CPU frequency scaling is basically useless without scaling the memory frequency. On the i.MX233, the EMI (external memory interface) and DRAM blocks are responsable for the DDR settings. This commits implements emi frequency scaling. Only some settings are implemented and the timings values only apply to mDDR (extracted from Sigmatel linux port) and have been checked to work on the Fuze+ and Zen X-Fi2/3. This feature is still disabled by default but I expected some battery life savings by boosting higher to 454MHz and unboosting lower to 64MHz. Note that changing the emi frequency is particularly tricky and to avoid writing it entirely in assembly we rely on the compiler to not use the stack except in the prolog and epilog (because it's in dram which is disabled when doing the change) and to put constant pools in iram which should always be true if the compiler isn't completely dumb and since the code itself is put in iram. If this proves to be insufficient, one can always switch the stack to the irq stack since interrupts are disabled during the change. Change-Id: If6ef5357f7ff091130ca1063e48536c6028f23ba

* imx233: use tick insteaf of msec to collect statisticsAmaury Pouly2012-12-26
| | | | | | | | | | The current code uses the msec irq to collect statistics and detect irq storms (debug). But this irq is triggered 1000 times per sec and we don't need that accuracy. This commit removes the msec irq and use the tick timer instead which is triggered only 100 times per second. Change-Id: If14b9503c89a3af370ef322678f10e35fafb4b8a

* fuze+: make sure lcd is ready before chaning a registerAmaury Pouly2012-12-26
| | | | | | | | | | The lcd driver does not wait for the refresh to be done to return from lcd_update(). This means that changing a register is unsafe if done in the middle of the redraw. This could happen when disabling the lcd for example. Make sure it doesn't happen by waiting for the lcdif to be ready. Change-Id: I43ec62a637dd61c3b2a3a6e131c1a9e8035524b1

* imx233: fix regulator voltage setting + always enable DCDC modeAmaury Pouly2012-12-26
| | | | | | | | | | | | | Make sure DCDC is running at boot (it is disabled by default when 5V is present and we don't want to rely on the bootloader to change this). When changing the voltage on a regulator, it usually takes 2ms for the voltage to stabilize. In DCDC mode, there is an irq to notify about the event so use it ! This is especially important when changing cpu frequency because increasing the cpu freq while the voltage is rising is unreliable. Change-Id: Icfe9ef3ee90156d1e17da0820d9041859f7f3bca

* usb: add support for hardware handled SET ADDR/CONFIGAmaury Pouly2012-12-07
| | | | | | | | | | | | | | | | | | | | | | | Some USB controllers like the one of the Rockchip 27xx handle some requests in pure hardware. This is especially a problem for two of them: - SET ADDR which is used by our core to track the DEFAULT/ADDRESS state and is required for the drivers to work properly - SET CONFIG which is used by our core to initialise the drivers by calling init_connection() In these cases we need a way to notify the core that such requests happened. We do this by exporting two functions which directly notify the core about these requests and perform the necessary init steps required without doing the actual USB transfers. Special care is needed because these functions could be called from an interrupt handler. For this reason we still use the usb_queue and introduce new IDs so that they are processed in order and safely. No functional change is intended, both in the usbstack and on targets without such quirks. Change-Id: Ie42feffd4584e88bf37cff018b627f333dca1140
* Add a true waveform display to the oscilloscope plugin.Michael Sevakis2012-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Adds some additional niftyness like a floating popup display that is implemented in an OSD library for use by other plugins. * Speed changes are now gradual for both views and follow a curve derived from some fiddling around to get a nice feel. * Refined a few behavioral things overall. It needs a bit of help from a direct PCM channel callback so it may capture PCM for waveform display. Also need a few other core routines to help out for the OSD. Messes with some keymaps. Some targets need keymaps to access the different views. Some devices can't support the additional view because it requires a large buffer ( > 1 s) for samples. If the plugin buffer is small, they can still use the popup display since the plugin is also much smaller in that case. Slow speed waveform needs some refining so it draws gradually like a real oscilloscope but I'll stick with what it is, for the moment.
