-Subject: [PATCH] clk-bcm2835: Add claim-clocks property
-
-The claim-clocks property can be used to prevent PLLs and dividers
-from being marked as critical. It contains a vector of clock IDs,
-as defined by dt-bindings/clock/bcm2835.h.
-
-Use this mechanism to claim PLLD_DSI0, PLLD_DSI1, PLLH_AUX and
-PLLH_PIX for the vc4_kms_v3d driver.
-
-Signed-off-by: Phil Elwell <phil@raspberrypi.org>
