5f7f2b6461 STM32 DMA2D: Use helper function when freeing layers. From Marco Krahl 2015-04-16 11:16:14 -06:00

5d221fa356 Add support for the new DMA2D features to the STM32F429i-Disco LTDC configuration. From Marco Krahl. 2015-04-16 09:11:53 -06:00
Gregory Nutt
7a6a5b7bd0 Defines a second interface for the dma2d controller. Controlling both LTDC and DMA2D was unpractical from the programmers view because both controllers are to different. LTDC only controls the display visibility but the DMA2D controller changes the content of the frame buffer (buffer of the layer).
The main features are:

1. DMA2D interface
   Supports the nuttx pixel formats:
   - FB_FMT_RGB8
   - FB_FMT_RGB24
   - FB_FMT_RGB16_565
   Dynamic layer allocation during runtime for the supported formats
   - The number of allocatable layer can be configured.
   Supported dma2d operation:
   - blit (Copy content from source to destination layer) also works with
     selectable area.
   - blend (Blend two layer and copy the result to a destination layer wich can
     be a third layer or one of the source layer) also works with selectable
     area.
   - fillarea (Fill a defined area of the whole layer with a specific color)

As a result of that the dma2d controller can't transfer data from the core coupled memory, CCM is disabled but usable by the ccm allocator. Currently the ccm allocator is used for allocating the layer structurei only. For the dma memory (layers frame buffer) memory is allocated from heap 2 and 3.

2. LTDC interface

   I have changed the api for the currently non implemented operations:
   - blit (Copy content from a dma2d layer to an ltdc layer) also works with
     selectable area.
   - blend (Blend two dma2d layer and copy the result to a destination ltdc
     layer) also  works with selectable area.

     Note! ltdc layer is a layer referenced by the ltdc interface. dma2d layer
     is a layer referenced by the dma2d interface.

     One of the most important questions for me was, How can i flexible use an
     ltdc layer with the dma2d interface, e.g. as source layer for dma2d
     operations?
     Get the layer id of the related dma2d layer by a special flag when using
     getlid() function of the ltdc interface and use the layer id to reference
     the specific dma2d layer by the dma2d interface.

     The ltdc coupled dma2d layers are predefined and can't be dynamically
     allocated of freed. They use the same frame buffer memory and the same
     color lookup table.

   Changes:
   - layer internal format of the clut table
   - interrupt handling for register reload (vertical vblank) instead using
     waiting loop
   - small fixes and refactoring

From Marco Krahl.

27bb133294 SAM3/4 and SAMV7 Serial: Serial interrupts left disabled.
A side-effect of changing serial settings via TERMIOS (such as tcsetattr) is that serial interrupts were being left disabled.  This is not a problem if the serial configuration is changed when there are no open references to the serial device.  In that case, serial interrupts are disabled and will not be enabled enabled until the serial device is first opened.  But it is fatal if the serial device is already opened and if there is a task waiting to receive data.  In that case, the side-effect of disabling interrupts is fatal:  That task is then left hanging with interrupts disabled.

f073092fad The STM32F4Discovery board doesn't come with a Low speed external oscillator so the default LSE source for the RTC doesn't work.
In stm32_rtcc.c the up_rtcinitialize() logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call that rightfully enables the lsi clock; but the next times, when the rtc is already setup, the rtc_resume() call does NOT start the lsi clock!

The right place to put LSE/LSI initialisation is inside stm32_stdclockconfig() in stm32fxxxxx_rcc.c.  Doing this I checked the possible uses of the LSI and the LSE sources: the LSI can be used for RTC and/or the IWDG, while the LSE only for the RTC (and to output the MCO1 pin)..

This change is not verifed for any other platforms.

d3beea967d Cortex-M7: Add support for enabled the D-Cache in write only mode.
SAMV7 Ethernet:  I- and D-Cache are now enabled in the netnsh/ configuration.  D-Cache is enabled in write-though mode.  This mode is necessary because the DMA descriptors are each 8-bytes in size but the D-Cache cache line is 32-bits in size. So it is impossible make coherency for every 8-byte DMA descriptor without write-through.

fedc213eec - ADC driver has been re-organized; configuration is now handled in code
instead of Kconfig to help reduce bloat and confusion.
- Timer changed to remove ADC coupling in Kconfig to code and moved
configuration up from arch/arm/src/tiva to configs/tm4c123g-launchpad/src.
- GPIO driver needed small fixes in the configuration routines and
discovered false-positive bugs in interrupt testing: interrupts are now
verified to actually be working reliably.
- Attempt to apply some consistency in the tiva arch/ level's interface
to the config/board/ level driver configuration.
