[PATCH 0/3] drm/komeda: Unify mclk/pclk/pipeline->aclk to one ACLK

Current komeda driver uses three dedicated clks for a specific purpose:
- mclk: main engine clock
- pclk: APB clock
- pipeline->aclk: AXI clock.

But per spec the komeda HW only has three input clks:
- ACLK: used for AXI masters, APB slave and most pipeline processing
- PXCLK for pipeline 0: output pixel clock for pipeline 0
- PXCLK for pipeline 1: output pixel clock for pipeline 1

So one ACLK is enough, no need to split it to three mclk/pclk/axiclk.

Depends on:
