Gregory Nutt 83cdb0c552 Squashed commit of the following: ... libc/semaphore: Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable. Changed all references to sem_getvalue in the OS to nxsem_getvalue(). sched/semaphore: Rename all internal private functions from sem_xyz to nxsem_xyz. The sem_ prefix is (will be) reserved only for the application semaphore interfaces. libc/semaphore: Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable. Changed all references to sem_init in the OS to nxsem_init(). sched/semaphore: Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function. sched/semaphoate: Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.		2017-10-03 12:52:31 -06:00

i2c_read.c	drivers: handle I2C_TRANSFER return value consistently. Some I2C peripherals transfers return zero on success, others number of completed transfers. Make drivers robust against this.	2017-08-04 07:31:36 -06:00
i2c_write.c	drivers: handle I2C_TRANSFER return value consistently. Some I2C peripherals transfers return zero on success, others number of completed transfers. Make drivers robust against this.	2017-08-04 07:31:36 -06:00
i2c_writeread.c	drivers: handle I2C_TRANSFER return value consistently. Some I2C peripherals transfers return zero on success, others number of completed transfers. Make drivers robust against this.	2017-08-04 07:31:36 -06:00
Kconfig	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 11:07:35 -06:00
