2016-08-01).
* drivers/sensors: Add KXJT9 Accelerometer driver from the Motorola
Moto Z MDK (2016-08-02).
* arch/arm/sim: Add a simulated I/O Expander driver (2016-08-03).
* configs/sim: Add logic to set the simulated I/O expander for testing
with apps/examples/gpio (2016-08-03).
* fs/fat: FAT performance improvement. In large files, seeking to a
position from the beginning of the file can be very time consuming.
ftell does lssek(fd, 0, SET_CURR). In that case, that is wasted time
since we are going to seek to the same position. This fix short-
circutes fat_seek() in all cases where we attempt to seek to current
position. Suggested by Nate Weibley (2016-08-03).
* tools/sethost.sh: Add sethost.sh. This is a script that you can use
to quickly change the host platform from Linux to Windows/Cygwin.
Might save you a lot of headaches (2016-08-03).
* arch/arm/src/tiva: Add tiva PWM lower-half driver implementation.
From Young (2016-08-05).
* drivers/spi/spi_transfer.c: Add a helper function that encapsulates
and manages a sequence of SPI transfers (2016-08-05).
* drivers/spi: Add an SPI character driver that will permit access to
the SPI bus for testing purposes. This driver is a simple wrapper
around spi_transfer() (2016-08-05).
* drivers/wireless: Add MFRC522 RFID ISO14443 and Mifare transceiver
driver. From Alan Carvalho de Assis (2016-08-06).
* configs/stm32f103-minimum: Add board support to MFRC522 driver. From
Alan Carvalho de Assis (2016-08-06).
* arch/renesas: Rename arch/sh to arch/renesas (2016-08-06).
* arch/arm/src/efm32, stm32, stm32l4: STM32 and EFM32 SPI drivers
adopted an incompatible conventions somewhere along the line. The
set the number of bits to negative when calling SPI_SETBITS which had
the magical side-effect of setting LSB first order of bit
transmission. This is not only a hokey way to pass control
information but is supported by no other SPI drivers. This change
three things: (1) It adds HWFEAT_LSBFIRST as a new H/W feature.
(2) It changes the implementations of SPI_SETBITS in the STM32 and
EFM32 derivers so that negated bit numbers are simply errors and it
adds the SPI_HWFEATURES method that can set the LSB bit order, and
(3) It changes all calls with negative number of bits from all
drivers: The number of bits is now always positive and SPI_HWFEATURES
is called with HWFEAT_LSBFIRST to set the bit order (2016-08-08).
* arch/arm/src/stm32: Add missing SPI2 and SPI3 support for STM32F3F3.
Add STM32F37XX DMA channel configuration. For STM32F37XX,
SYSCFG_EXTICR_PORTE defined twice. From Alan Carvalho de Assis
(2016-08-08).
* arch/arm/src/stm32: Make stm32_pwr_enablebkp thread safe. From
Max Neklyudov (2016-08-09).
* arch/arm/src/stm32: SAM3/4 GPIO: Enable peripheral clock for GPIO port
when GPIO is configured as input. The value of a GPIO input is only
sampled when the peripheral clock for the port controller the GPIO
resides in is enabled. Therefore we need to enable the clock even when
polling a GPIO. From Wolfgang Reissnegger (2016-08-09).
* arch/arm/src/tiva: Fix two bugs of tiva pwm lower-half driver
implementation. From Young (2016-08-10).
* sched/group: Explicitly initialize the group tg_exitsem with
sem_init(). The existing logic worked because the correct
initialization value is all zero, but it is better to initialize the
semaphore explicitly (2016-08-10).
* arch/arm/stm32: Fix bad pllmul values for STM32F1XX connectivity line.
STM32F1XX connectivity line supports only x4, x5, x6, x7, x8, x9 and
x6.5 values. From Michał Łyszczek (2016-08-11).
* include/nuttx/timers: Add oneshot timer lower half interface
(2016-08-11).
* arch/arm/src/stm32: Add a experimental oneshot, lower-half driver for
STM32 (2016-08-11).
* arch/arm/src/samv7: Add option to support oneshot timer without free-
running timer. Add oneshot lower half driver (2016-08-11).
* arch/arm/src/sama5: Add option to support oneshot timer without free-
running timer. Add oneshot lower half driver (2016-08-11).
* arch/arm/src/sam34: SAM4CM: Add option to support oneshot timer without
free-running timer. Add oneshot lower half driver (2016-08-11).
* arch/arm/src/stm32l4: Add oneshot lower half driver (2016-08-11).
* libc/stdlib: strtod() was not returning endptr on error conditions
(2016-08-11).
* libc/math: floor(), floorf(), and floorl(): Fix logic error. Was not
correctly handling negative integral value (2016-08-11).
* configs/sim: Add a configuration useful for testing Mini Basic
(2016-08-12).
* drivers/timers: Add an upper-half, oneshot timer character driver
(2016-08-12).
* arch/sim/src: Add a simulated oneshot lowerhalf driver (2016-08-12).
* arch/arm/src/stm32: STM32F3 SPI: Fix the number of bit setting for
the F3. It works differently than for other STM32 parts (2016-08-12).
* arch/arm/stm32 and stm32l4: Enabling SPI DMA loses other bits in CR2
(2016-08-13).
* arch/arm/src/stm32: STM32F3 SPI: Cannot write always 16-bit value to
DR register because of how the F3 implements data packing (2016-08-13).

* Description:
* Exchange a block of data on SPI without using DMA
*
* REVISIT: This function could be much more efficient by exploiting (1) RX and TX
* FIFOs and (2) the STM32 F3 data packing.
*
* Input Parameters:
* dev - Device-specific state data
* txbuffer - A pointer to the buffer of data to be sent
