Subject: [PATCH 0/3] clk-raspberrypi: Add support for few more clocks

These patches inline functionality between driver available
on RaspberryPi repository and mainline.

Dave Stevenson (1):
clk: bcm: rpi: Add the BCM283x pixel clock.

Dom Cobley (2):
clk-raspberrypi: Also support HEVC clock
clk-raspberrypi: Support VEC clock

Subject: [PATCH 3/3] clk: bcm: rpi: Add the BCM283x pixel clock.

From: Dave Stevenson <[email protected]>

The clk-bcm2835 handling of the pixel clock does not function
correctly when the HDMI power domain is disabled.

The firmware supports it correctly, so add it to the
firmware clock driver.
