For programs with the dependencies logic in pthread_once callback , using global locks may cause deadlock:
task A
pthread_once()
|
|-> nxrmutex_lock(&g_lock);
-> init_routine(); // callback to wait task B
task B
pthread_once()
|
->nxrmutex_lock(&g_lock); // Deadlock
->init_routine(); // hold resource to wake up task A

convert from body coordinate system to right-hand
coordinate system.
Example:
Compared to the standard coordinate system,
the x-axis and y-axis are interchanged and have opposite directions,
the z-axis remains normal.
body coordinate ----> right-hand coordinate
+x +y
| |
| |
| |
| |
-y<-------. .------>+x
/ /
/ /
/ /
/ /
+z +z
So for the above conversion, using "P3" to represent transformation relationships
The front is 1 0 2, which represents the y x z axis.
The standard order is 0 1 2, so y and x are interchanged.
The following -1 1 1 indicates the direction of the axis.
The standard is 1 1 1. Because the current y-axis is opposite to
the standard x-axis, it is -1.
static const struct sensor_axis_map_s g_remap_tbl[] =
{
{ 0, 1, 2, 1, 1, 1 }, /* P0 */
{ 1, 0, 2, 1, -1, 1 }, /* P1 */
{ 0, 1, 2, -1, -1, 1 }, /* P2 */
{ 1, 0, 2, -1, 1, 1 }, /* P3 */
{ 0, 1, 2, -1, 1, -1 }, /* P4 */
{ 1, 0, 2, -1, -1, -1 }, /* P5 */
{ 0, 1, 2, 1, -1, -1 }, /* P6 */
{ 1, 0, 2, 1, 1, -1 }, /* P7 */
};
you can call the function sensor_remap_vector_raw16 and pass P3 parameters
to perform the conversion.

Rename a function name to register SCU sensor driver
from ak09912_register to ak09912_scu_register.
Channel polarity can now be set with PWMIOC_SETCHARACTERISTICS ioctl
command as field cpol was added to pwm_info_s structure. This way the
polarity can be easily set from application layer for each channel
apart and also can be change on at runtime if required (although this is
not likely).
Helper defines were also added to simplify the definition of low and high
polarity level. Architecture level should take care of writing the
polarity to correct MCU registers.

Allows the debug behavior to be specified as part of the board, architecture or chip configuration. This is useful when using out-of tree custom board configurations.
Documentation for PWMIOC_SETCHARACTERISTICS ioctl command mentioned
that this command will neither start nor stop the pulsed output. This
however is incorrect as PWMIOC_SETCHARACTERISTICS command leads to
pwm_start() function which starts the pulsed output.
While this might not be the correct behaviour (I would probably welcome
the option to set PWM characteristics without starting the pulsed output)
it is the way the PWM driver is coded for many architectures. Future
enhancement might be to add function pwm_setchar() for example to just
set characteristics without starting the PWM output.
