Subject: [PATCH v2 1/2] ARC: [plat-axs10x]: use pgu pll instead of fixed clock
Date: Wed, 20 Nov 2019 14:29:22 +0300	[thread overview]
Message-ID: <20191120112923.431-1-Eugeniy.Paltsev@synopsys.com> (raw)

Use PLL driver instead of fixed-clock for PGU pixel clock.
That allows us to support wider range of graphic modes.

Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>

Changes v1->v2:
 * add missing input_clk node to AXS101. No changes for AXS103 /
   AXS103 SMP.
