Subject: [PATCH 1101/1135] ARM: dts: Fix camera sync parameters
|
||
|
|
|
||
|
|
The camera sync parameter declarations include are invalid in that they
|
||
|
|
have both embedded string values and following cell values. The
|
||
|
|
intention here was to use the cell values, but the embedded "0" was
|
||
|
|
not removed as it should have been.
|
||
|
|
|
||
|
|
The implication of this mistake is that inverted sync flags would be
|
||
|
|
ignored because the 0 value corresponds to GPIO_ACTIVE_HIGH. The
|
||
|
|
extra cell value would be treated as the start of another override,
|
||
|
|
but then ignored because the end of the parameter is reached.
|
||
|
|
|
||
|
|
These errors should have been picked up by the automated checks, but
|
||
|
|
the base dts files weren't subjected to the same validation. This has
|
||
|
|
now been corrected.
