db0cdfc407 Squashed commit of the following: 
arch/arm/src/imxrt:  May eDMA channel linking a configuration option.  Add support to select the DMA channel priority and pre-emption controls.
    arch/arm/src/imxrt:  Update some HowTo comments in the eDMA header file.
    arch/arm/src/imxrt:  Fix a logic error in parmater passing.  Caller does not know actual channel number when setting up linked channel, only the channel handler.

fe44948ea4 arch/arm/src/lpc17xx/lpc17_usbdev.c: Fix loss of RX initiatives. USB bulk endpoints are double buffered on LPC17xx MCUs. This means that up to two packets might be received on an OUT endpoint that can not be handled immediately if the receive request queue is empty. Thus, rxpending must be a counter not a boolean flag. 2018-05-20 12:42:30 -06:00

76f0e68812 arch/arm/src/stm32: Added Vbat measurement to adc driver for STM32F20xx and STM32F4xxx. 
As with the MCU temperature and VREFINT measurement, this patch requires user to enable the corresponding channel first. For Vbat channel the ioctl cmd is IO_ENABLE_DISABLE_VBAT_CH, and its arg should be a pointer to bool which must be true to enable and false to disable the Vbat channel.

Moreover, since Vbat input contains a built-in voltage divider, it is highly suggested to disable Vbat input channel after measurement is done in order to prevent battery drain through the divider.

    Add support for the second SDMMC device.

    The second SDMMC device was already supported but
    the clock was never enabled.  This fixes that.

4a9a421c34 Back out part of f4bcaa4fc2dc2f06d5632d3b74f43c25a6e7e845.If CONFIG_ARCH_IDLE_CUSTOM is defined, then it should not use the version of lc823450_idle.c in arch/arm/src/lc823450. That part was correct before the PR. If CONFIG_ARCH_IDLE_CUSTOM, then the build should use a custom IDLE loop in the board src/ directory. 2018-05-11 06:26:01 -06:00
