One is required for accessing LCD controller registers (peripheral clock), while other (AXI clock) can be optionally used as a pixel clock source for the panel. LCDC can alternatively use different clocks than the Display 1 AXI clock for generating the pixel clock: the second AXI clock (fixed in this commit too), the HDMI PLL, or the AXI bus clock. They should really be controlled independently.

I picked up the other one. It is. Sorry for not marking it as such -- I forgot I already sent it. The patches are indeed the same. Thanks for picking it up.

The dt-bindings patch assumes the SP clock is not there as it probably was a mistake to expose it (see the 'Revert "dt-bindings: marvell,mmp2: Add clock id for the SP clock' patch sent separately).
