| | | | | | | | This add ths following ioctl calls to the sc16is752 driver: - TIOCMGET - TIOCMSET - TIOCMBIS - TIOCMBIC

* Xilinx AXI I2C driver IP race condition causes clock glitch.Chris Johns2018-02-011-1/+5
| | | | | | | Setting the PIRQ to 0 before reading the data produces a short clock pulse. Moving the write to after reading the data fixes the issue. Close #3173
* Remove make preinstallChris Johns2018-01-2517-2716/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.

| | | | Close #3163.
* i2c: Fix EEPROM driver program timeout handlingSebastian Huber2017-10-021-4/+13
| | | | | | | | The RTEMS_MILLISECONDS_TO_TICKS() macro doesn't round up. Do not use it to calculate the program timeout in ticks. Check program done condition after the timeout check to account for pre-emptions. Update #3162.

* Add I2C driver frameworkSebastian Huber2014-11-205-0/+1092
| | | | | | | | | | | | | | | | | This I2C driver framework has some major differences compared to libi2c. * It is compatible to the Linux I2C user-space API. * It uses generic IMFS nodes and thus reduces the levels of indirection. * The drivers don't have to mess around with minor numbers to get their state information. * No arbitrary bus controller model is assumed. The main task of an I2C bus controller driver is to process I2C messages. How this is done is private to the driver. * Scatter/gather operations are supported (I2C_M_NOSTART).
