[PATCH v5 1/4] dt-bindings: clock: versaclock3: Add description for #clock-cells property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add description for "#clock-cells" property to map indexes to the clock
output in the Table 3. ("Output Source") in the 5P35023 datasheet
(ie: {REF,SE1,SE2,SE3,DIFF1,DIFF2}. Also update the "assigned-clock-rates"
in the example.

While at it, replace clocks phandle in the example from x1_x2->x1 as
X2 is a different 32768 kHz crystal.

v4->v5:
 * Added description for "#clock-cells" property to map indexes to the
   clock output.
 * Updated commit header and description to reflect this change.
 * Dropped fixes tag.
 * Retained Ack tag from Conor and Krzysztof as it is trivial change.
v3->v4:
 * Dropped clock-output-names as there is no validation for it and people
   can get it wrong.
 * Updated commit header, description and example to reflect this change
 * Retained Ack tag from Conor and Krzysztof as it is trivial change.
v2->v3:
 * No change.
v1->v2:
 * Updated commit description to make it clear it fixes
   "assigned-clock-rates" in the example based on 5P35023 datasheet.
