This has updated comments against v2 of these patches. Two new clocks "master" and "slave" are defined for ccdc driver as per comments from Kevin Hilman. This adds platform code for ccdc driver on DM355 and DM6446.

The ccdc now uses a generic name for clocks. "master" and "slave". On individual platforms these clocks will inherit from the platform specific clock. This will allow re-use of the driver for the same IP across different SoCs. Following are the changes done:- 1) clocks are configured using generic clock names 2) converting the driver to a platform driver 3) cleanup - consolidate all static variables inside a structure, ccdc_cfg Reviewed-by: Kevin Hilman <khilman@deeprootsystems.com> Reviewed-by: Vaibhav Hiremath <hvaibhav@ti.com> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Muralidharan Karicheri <m-karicheri2@ti.com> --- Rebased to latest linux-next tree Applies to linux-next branch of v4l-dvb drivers/media/video/davinci/dm355_ccdc.c | 409 +++++++++++++++++++----------- 1 files changed, 256 insertions(+), 153 deletions(-) diff --git a/drivers/media/video/davinci/dm355_ccdc.c b/drivers/media/video/davinci/dm355_ccdc.c index 3143900..fc716ed 100644 --- a/drivers/media/video/davinci/dm355_ccdc.c +++ b/drivers/media/video/davinci/dm355_ccdc.c @@ -37,8 +37,11 @@ #include <linux/platform_device.h> #include <linux/uaccess.h> #include <linux/videodev2.h> +#include <linux/clk.h> + #include <media/davinci/dm355_ccdc.h> #include <media/davinci/vpss.h> + #include "dm355_ccdc_regs.h" #include "ccdc_hw_device.h" @@ -46,67 +49,75 @@ MODULE_LICENSE("GPL");

The ccdc now uses a generic name for clocks. master and slave. On individual platforms these clocks will inherit from the platform specific clock. This will allow re-use of the driver for the same IP across different SoCs. Following are the changes done:- 1) clocks are configured using generic clock names 2) converting the driver to a platform driver 3) cleanup - consolidate all static variables inside a structure, ccdc_cfg Reviewed-by: Kevin Hilman <khilman@deeprootsystems.com> Reviewed-by: Vaibhav Hiremath <hvaibhav@ti.com> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Muralidharan Karicheri <m-karicheri2@ti.com> --- Rebased to latest linux-next tree Applies to linux-next tree of v4l-dvb drivers/media/video/davinci/dm644x_ccdc.c | 360 ++++++++++++++++++----------- 1 files changed, 224 insertions(+), 136 deletions(-) diff --git a/drivers/media/video/davinci/dm644x_ccdc.c b/drivers/media/video/davinci/dm644x_ccdc.c index d5fa193..7e35269 100644 --- a/drivers/media/video/davinci/dm644x_ccdc.c +++ b/drivers/media/video/davinci/dm644x_ccdc.c @@ -37,8 +37,11 @@ #include <linux/platform_device.h> #include <linux/uaccess.h> #include <linux/videodev2.h> +#include <linux/clk.h> + #include <media/davinci/dm644x_ccdc.h> #include <media/davinci/vpss.h> + #include "dm644x_ccdc_regs.h" #include "ccdc_hw_device.h" @@ -46,32 +49,44 @@ MODULE_LICENSE("GPL");

This has updated comments against v1 of these patches. In this patch, the clock configuration is moved to ccdc driver since clocks are configured for ccdc. Also adding proper error codes for ccdc register function and removing the ccdc memory resource handling.

Here the clock configuration isn't moved, it's removed. You should mention it being removed here and added to platform-specific code in subsequent patches. Sorry to be so nit-picky about the comments, but having a well-written and descriptive changelog is extremely importanty. For the benefit of reading the git history later, and also for those of us less familiar with the details of these drivers, we rely heavily on a good changelog.

Following are the changes from v3 :- - replaced CLK entries with clk_add_alias() calls - removed unused vpss_master and vpss_slave entries This combines the two patches sent earlier to change the clock configuration and converting ccdc drivers to platform drivers. This has updated comments against v2 of these patches. Two new clocks "master" and "slave" are defined for ccdc driver as per comments from Kevin Hilman. This adds platform code for ccdc driver on DM355 and DM6446.

The ccdc now uses a generic name for clocks. "master" and "slave". On individual platforms these clocks will inherit from the platform specific clock. This will allow re-use of the driver for the same IP across different SoCs. Following are the changes done:- 1) clocks are configured using generic clock names 2) converting the driver to a platform driver 3) cleanup - consolidate all static variables inside a structure, ccdc_cfg Reviewed-by: Kevin Hilman <khilman@deeprootsystems.com> Reviewed-by: Vaibhav Hiremath <hvaibhav@ti.com> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Muralidharan Karicheri <m-karicheri2@ti.com> --- Applies to linux-next branch of v4l-dvb drivers/media/video/davinci/dm355_ccdc.c | 409 +++++++++++++++++++----------- 1 files changed, 256 insertions(+), 153 deletions(-) diff --git a/drivers/media/video/davinci/dm355_ccdc.c b/drivers/media/video/davinci/dm355_ccdc.c index 3143900..fc716ed 100644 --- a/drivers/media/video/davinci/dm355_ccdc.c +++ b/drivers/media/video/davinci/dm355_ccdc.c @@ -37,8 +37,11 @@ #include <linux/platform_device.h> #include <linux/uaccess.h> #include <linux/videodev2.h> +#include <linux/clk.h> + #include <media/davinci/dm355_ccdc.h> #include <media/davinci/vpss.h> + #include "dm355_ccdc_regs.h" #include "ccdc_hw_device.h" @@ -46,67 +49,75 @@ MODULE_LICENSE("GPL");

The ccdc now uses a generic name for clocks. master and slave. On individual platforms these clocks will inherit from the platform specific clock. This will allow re-use of the driver for the same IP across different SoCs. Following are the changes done:- 1) clocks are configured using generic clock names 2) converting the driver to a platform driver 3) cleanup - consolidate all static variables inside a structure, ccdc_cfg Reviewed-by: Kevin Hilman <khilman@deeprootsystems.com> Reviewed-by: Vaibhav Hiremath <hvaibhav@ti.com> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Muralidharan Karicheri <m-karicheri2@ti.com> --- Applies to linux-next tree of v4l-dvb drivers/media/video/davinci/dm644x_ccdc.c | 360 ++++++++++++++++++----------- 1 files changed, 224 insertions(+), 136 deletions(-) diff --git a/drivers/media/video/davinci/dm644x_ccdc.c b/drivers/media/video/davinci/dm644x_ccdc.c index d5fa193..7e35269 100644 --- a/drivers/media/video/davinci/dm644x_ccdc.c +++ b/drivers/media/video/davinci/dm644x_ccdc.c @@ -37,8 +37,11 @@ #include <linux/platform_device.h> #include <linux/uaccess.h> #include <linux/videodev2.h> +#include <linux/clk.h> + #include <media/davinci/dm644x_ccdc.h> #include <media/davinci/vpss.h> + #include "dm644x_ccdc_regs.h" #include "ccdc_hw_device.h" @@ -46,32 +49,44 @@ MODULE_LICENSE("GPL");

This has updated comments against v1 of these patches. In this patch, the clock configuration is moved to ccdc driver since clocks are configured for ccdc. Also adding proper error codes for ccdc register function and removing the ccdc memory resource handling.

I am trying to setup mercurial to send the pull request, but will take few more days to be fully functional. Meanwhile please merge the attached patches. The kernel upstream tree is at 2.6.33.rc3. We have a bunch of patches planned for 2.6.34. So please start merging these patches to the linux-next so that they can make to 2.6.34. You might have seen a bunch of patches from Vaibhav as well that is being reviewed on the list. Regarding the merge of arch patches, I would let Kevin to comment on how to handle the merge. I have re-created the arch patches against the Linus tree as per Kevin's suggestion. Thanks. Murali Karicheri Software Design Engineer Texas Instruments Inc.
