2014-12-23[media] smiapp-pll: include linux/device.h in smiapp-pll.c, not in smiapp-pll.hSakari Ailus1-0/+1
struct device has a forward declaration in the header already. The header is only needed in the .c file. Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2014-12-23[media] smiapp: Remove FSF's address from the license headerSakari Ailus1-6/+0
Remove FSF's address information from the license header in the smiapp driver and the smiapp-pll PLL calculator. This should no longer be needed, and would be rendered outdated in case the FSF chooses to relocate its office.

2014-10-28[media] smiapp-pll: Add pixel rate in pixel array as output parametersSakari Ailus1-0/+1
The actual pixel array pixel rate may be something else than vt_pix_clk_freq on some implementations. Add a new field which contains the corrected value.

2014-10-28[media] smiapp: Remove validation of op_pix_clk_divSakari Ailus1-5/+0
op_pix_clk_div is directly assigned and not calculated. There's no need to verify it. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2014-10-28[media] smiapp-pll: Don't validate OP clocks if there are noneSakari Ailus1-0/+8
For profile 0 sensors (which have no OP clocks), the OP limits are in fact VT limits. Do not verify them again. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2014-10-28[media] smiapp-pll: Calculate OP clocks only for sensors that have themSakari Ailus1-30/+52
Profile 0 sensors have no OP clock branck in the clock tree. The PLL calculator still calculated them, they just weren't used for anything.

2014-10-28[media] smiapp-pll: Unify OP and VT PLL structsSakari Ailus1-30/+30
Uniform representation for VT and OP clocks. This is preparation for calculating the VT clocks using the OP clock code.

2014-10-28[media] smiapp-pll: The clock tree values are unsigned --- fix debug printsSakari Ailus1-47/+47
These values are unsigned, so use %u instead of %d. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2013-08-22[media] smiapp-pll: Add a few comments to PLL calculationSakari Ailus1-0/+17
The PLL calculation heuristics is rather complicated and and is often difficult to understand to its original author. Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2012-10-29[media] smiapp-pll: Constify limits argument to smiapp_pll_calculate()Laurent Pinchart1-18/+17
The limits are input parameters and should not be modified by the smiapp_pll_calculate() function. Make them const. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-10-29[media] smiapp-pll: Create a structure for OP and VT limitsLaurent Pinchart1-27/+27
OP and VT limits have identical fields, create a shared structure for both. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Sakari Ailus <sakari.ailus@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-10-29[media] smiapp-pll: Parallel bus supportSakari Ailus1-4/+15
Support sensors with parallel interface. Make smiapp_pll.flags also 8-bit so it fits nicely into two 32-bit words with the other 8-bit fields.

2012-10-29[media] smiapp-pll: Try other pre-pll divisorsSakari Ailus1-58/+73
The smiapp pll calculator assumed that the minimum pre-pll divisor was perfect. That may not always be the case, so let's try the others, too. Typically there are just a few alternatives.
