2016-10-21[media] smiapp-pll: Don't complain aloud about failing PLL calculationSakari Ailus1-1/+2
Don't complain about a failure to compute the pre_pll divisor. The function is used to determine whether a particular combination of bits per sample value and a link frequency can be used, in which case there are lots of unnecessary driver messages. During normal operation the failure generally does not happen. Use dev_dbg() instead.

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 This should no longer be needed, and would be rendered outdated in case the FSF chooses to relocate its office.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-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>

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.
