[POWERPC] CPM_UART: Removed __init from cpm_uart_init_portdesc to fix warning

2007-05-10T04:44:58+00:00

cpm_uart_init_portdesc is referenced from non-init code and thus we were getting the following warning: WARNING: drivers/built-in.o - Section mismatch: reference to .init.text:cpm_uart_init_portdesc from .text between 'cpm_uart_init' (at offset 0x18020) and 'cpm_uart_drv_remove' Signed-off-by: Kumar Gala

[POWERPC] CPM_UART: cpm_uart_set_termios should take ktermios, not termios

2007-05-10T04:05:48+00:00

This eliminates some warnings. Signed-off-by: Scott Wood Signed-off-by: Kumar Gala

[POWERPC] Change rheap functions to use ulongs instead of pointers

2007-05-10T04:01:43+00:00

The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

[POWERPC] Fix compile failure in cpm_uart_cpm2

2007-02-16T03:00:19+00:00

Fix bug that exists in kernel.org since 2.6.17rc4 - compiles fail if CONFIG_SERIAL_CPM_SMC is defined. Tested on a board using SMC1 console. Signed-off-by: Paul Gortmaker Signed-off-by: Paul Mackerras

[POWERPC] Fix kernel build errors for mpc8272ads and mpc8560ads

2007-02-07T03:03:20+00:00

Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

[POWERPC] cpm_uart: OF-related fix for CPM1

2007-02-07T01:00:32+00:00

This makes cpm uart able to work using OF-passed parameters in case of CPM stuff (found on most mpc8xx reference and custom boards). The idea is to keep ppc stuff working yet making it able to be used for powerpc. Signed-off-by: Vitaly Bordug Signed-off-by: Paul Mackerras

[POWERPC] CPM_UART: Fix inconsistency of function definition

2006-12-04T09:39:25+00:00

The below hunk was missed from the recent patch, and now, there are somewhat inconsistent definitions: in cpm_uart.h: int __init cpm_uart_init_portdesc(void); in cpm_uart_cpm1.c: int __init cpm_uart_init_portdesc(void) { } in cpm_uart_cpm2.c: int cpm_uart_init_portdesc(void) { } Signed-off-by: Kalle Pokki Signed-off-by: Vitaly Bordug Signed-off-by: Paul Mackerras

[POWERPC] CPM_UART: Fix non-console initialisation

2006-11-10T10:35:36+00:00

The cpm_uart driver is initialised incorrectly, if there is a frame buffer console, and CONFIG_SERIAL_CPM_CONSOLE is defined. The driver fails to call cpm_uart_init_portdesc() and set_lineif() in this case. Signed-off-by: Kalle Pokki Signed-off-by: Vitaly Bordug Signed-off-by: Paul Mackerras

[POWERPC] CPM_UART: Fix non-console transmit

2006-11-10T10:26:40+00:00

The SMC and SCC hardware transmitter is enabled at the wrong place. Simply writing twice to the non-console port, like $ echo asdf > /dev/ttyCPM1 $ echo asdf > /dev/ttyCPM1 puts the shell into endless uninterruptible sleep, since the transmitter is stopped after the first write, and is not enabled before the shutdown function of the second write. Thus the transmit buffers are never emptied. Signed-off-by: Kalle Pokki Signed-off-by: Vitaly Bordug Signed-off-by: Paul Mackerras
