v4l: omap3isp: Fix sub-device power management code

2015-09-29T17:26:07Z

commit 9d39f05490115bf145e5ea03c0b7ec9d3d015b01 upstream. Commit 813f5c0ac5cc ("media: Change media device link_notify behaviour") modified the media controller link setup notification API and updated the OMAP3 ISP driver accordingly. As a side effect it introduced a bug by turning power on after setting the link instead of before. This results in sub-devices not being powered down in some cases when they should be. Fix it.

[media] media: omap3isp: remove unused clkdev

2015-04-10T13:25:30Z

No merged platform supplies xclks via platform data. As we want to slightly change the clkdev interface, rather than fixing this unused code, remove it instead. Signed-off-by: Russell King Signed-off-by: Laurent Pinchart Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Deprecate platform data support

2015-04-02T19:48:07Z

Print a warning when the driver is used with platform data. Existing platform data users should move to DT now. Signed-off-by: Sakari Ailus Acked-by: Laurent Pinchart Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Add support for the Device Tree

2015-04-02T19:47:48Z

Add the ISP device to omap3 DT include file and add support to the driver to use it. Also obtain information on the external entities and the ISP configuration related to them through the Device Tree in addition to the platform data.

[media] omap3isp: Replace many MMIO regions by two

2015-04-02T19:45:07Z

The omap3isp MMIO register block is contiguous in the MMIO register space apart from the fact that the ISP IOMMU register block is in the middle of the area. Ioremap it at two occasions, and keep the rest of the layout of the register space internal to the omap3isp driver.

[media] omap3isp: Move the syscon register out of the ISP register maps

2015-04-02T19:44:18Z

The syscon register isn't part of the ISP, use it through the syscom driver regmap instead. The syscom block is considered to be from 343x on ISP revision 2.0 whereas 15.0 is assumed to have 3630 syscon.

[media] omap3isp: Replace mmio_base_phys array with the histogram block base

2015-04-02T19:42:52Z

Only the histogram sub-block driver uses the physical address. Do not store it for other sub-blocks. Signed-off-by: Sakari Ailus Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Calculate vpclk_div for CSI-2

2015-04-02T19:42:04Z

The video port clock is l3_ick divided by vpclk_div. This clock must be high enough for the external pixel rate. The video port requires two clock cycles to process a pixel. Signed-off-by: Sakari Ailus Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: Refactor device configuration structs for Device Tree

2015-04-02T19:41:01Z

Make omap3isp configuration data structures more suitable for consumption by the DT by separating the I2C bus information of all the sub-devices in a group and the ISP bus information from each other. The ISP bus information is made a pointer instead of being directly embedded in the struct. In the case of the DT only the sensor specific information on the ISP bus configuration is retained. The structs are renamed to reflect that. After this change the structs needed to describe device configuration can be allocated and accessed separately without those needed only in the case of platform data. The platform data related structs can be later removed once the support for platform data can be removed.
