cpm_uart: Pass actual dev ptr to dma_* in ucc and cpm_uart serial

2008-09-19T18:34:04+00:00

We're currently passing NULL, and really shouldn't be. Signed-off-by: Becky Bruce Acked-By: Timur Tabi Signed-off-by: Kumar Gala

cpm_uart: Remove !CONFIG_PPC_CPM_NEW_BINDING code

2008-06-26T06:49:04+00:00

Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING. Signed-off-by: Kumar Gala

[POWERPC] cpm_uart: Allocate DPRAM memory for SMC ports on CPM2-based platforms.

2008-04-17T06:01:36+00:00

This patch allocates parameter RAM for SMC serial ports without relying on previous initialisation by a boot loader or a wrapper layer. SMC parameter RAM on CPM2-based platforms can be allocated anywhere in the general-purpose areas of the dual-port RAM. The current code relies on the boot loader to allocate a section of general-purpose CPM RAM and gets the section address from the device tree. This patch modifies the device tree address usage to reference the SMC parameter RAM base pointer instead of a pre-allocated RAM section and allocates memory from the CPM dual-port RAM when initialising the SMC port. CPM1-based platforms are not affected. Signed-off-by: Laurent Pinchart Acked-by: Scott Wood Signed-off-by: Kumar Gala

[POWERPC] Move CPM command handling into the cpm drivers

2007-12-14T04:47:16+00:00

This patch moves the CPM command handling into commproc.c for CPM1 and cpm2_common.c. This is yet another preparation to get rid of drivers accessing the CPM via the global cpmp. Signed-off-by: Jochen Friedrich Acked-by: Scott Wood Acked-by: Arnd Bergmann Signed-off-by: Vitaly Bordug

[POWERPC] cpm_uart: sparse fixes

2007-10-04T01:36:35+00:00

Mostly a bunch of direct access to in/out conversions, plus a few cast removals, __iomem annotations, and miscellaneous cleanup. Signed-off-by: Scott Wood Signed-off-by: Kumar Gala

[POWERPC] cpm_uart: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING is set.

2007-10-04T01:36:35+00:00

The existing OF glue code was crufty and broken. Rather than fix it, it has been removed, and the serial driver now talks to the device tree directly. The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms are dropped from arch/ppc (which will hopefully be soon), and existing arch/powerpc boards that I wasn't able to test on for this patchset get converted (which should be even sooner).

[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] 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] 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
