* CRIS v32: Update signal handling in kernel/signal.cJesper Nilsson2008-02-081-88/+56
| | | | | | | | | | | - do_signal now returns void, and does not have the previous signal set as a parameter. - Remove sys_rt_sigsuspend, we can use the common one instead. - Change sys_sigsuspend to be more like x86, don't call do_signal here. - handle_signal, setup_frame and setup_rt_frame now return -EFAULT if we've delivered a segfault, which is used by callers to perform necessary cleanup. - Break long lines, correct whitespace and formatting errors.
* CRIS v32: Update boot/rescue/rescue.ldJesper Nilsson2008-02-081-7/+30
| | | | - Update to work for ETRAX FS and ARTPEC-3
* CRIS v10: Update drivers/gpio.c, fix locking and general improvements.Jesper Nilsson2008-02-081-359/+228
| | | | | | | | | | | | - Change all spin_lock/local_irq_save to spin_lock_irqsave. - Change multiple returns in functions where we have a lock to goto out. - Correct number of arguments to gpio_poll_timer_interrupt, gpio_pa_interrupt. - Break out gpio_write logic to smaller functions to make it readable. - In setget_input and setget_output, avoid extra if-indent level. - Change name LED_* -> CRIS_LED_* to avoid name clash. - Don't use braces around single statement ifs. - Fix whitespace errors. - Remove useless CVS id and log.
* CRIS v32: Change names of config variable and register field for data available.Jesper Nilsson2008-02-081-6/+6
| | | | | - CONFIG_ETRAXFS_SIM -> CONFIG_ETRAX_VCS_SIM - ser_intr_mask.data_avail -> ser_intr_mask.dav
* CRIS v32: Change debug and formatting in kernel/fasttimer.cJesper Nilsson2008-02-081-9/+7
| | | | | | | - Don't use SANITYCHECK(x) as a macro, test FAST_TIMER_SANITY_CHECKS with ifdef. This makes it possible for automatic indent etc to work. - Correct some whitespace errors. - Don't initialize static variable.
* CRIS v32: Update kernel/crisksyms.cJesper Nilsson2008-02-081-1/+6
| | | | | | - Include pinmux.h from machine specific directory. - Add some more symbols: crisv32_pinmux_alloc, crisv32_pinmux_dealloc_fixed, crisv32_io_get_name and crisv32_io_get

* CRIS v32: Update driver for RTC chip pcf8563.Jesper Nilsson2008-02-081-133/+163
| | | | | | | | | | | | - Moved all calls to register_chrdev to a function called by module_init. - Added mutex locking. - Added better error handling at start up. - Added BIN_TO_BCD of the month value before it is saved to the RTC. - Corrected the month value returned by pcf8563_readreg. - Cache the voltage low value at driver init so the battery status information does not get 'accidentally' cleared when setting the RTC time. - Removed obsolete CONFIG_ETRAX_RTC_READONLY - Voltage low ioctl():s RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR

* CRIS v10: Update kernel/io_interface_mux.cJesper Nilsson2008-02-081-107/+408
| | | | | | | | | | Fixed a bug where two interfaces using pins in the same pin group could not be allocated at the same time even if there where no pin collisions. Change all restore and returns into goto exit pattern. Also, remove useless CVS id and correct chapter reference for ETRAX100LX Designer's Reference in comment.
* CRIS v10: Setup serial port 2 to avoid accidental TXD pulse on startup.Jesper Nilsson2008-02-081-178/+43
| | | | | | | | | If serial port 2 is used, select it in R_GEN_CONFIG. If serial port 2 is used, setup the control registers for the port. This is done to avoid a pulse on the TXD line during start up, which could disturb some units. Also, remove useless CVS id and log.
