From c72c553249bb73705f594e292a8f8750027fbcbe Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Mon, 27 Oct 2014 17:40:44 +0100 Subject: ARM: imx: clk-vf610: define PLL's clock tree So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized by boot loader and the kernel code defined fixed rates according to those default configurations. Beginning with the USB PLL7 the code started to initialize the PLL's itself (using imx_clk_pllv3). However, since commit dc4805c2e78ba5a22ea1632f3e3e4ee601a1743b (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver) imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits, hence the USB PLL were not configured correctly anymore. This patch not only fixes those USB PLL's, but also makes use of the imx_clk_pllv3 for all PLL's and alignes the code with the PLL support of the i.MX6 series.

In order to keep the same behaviour as previous kernel versions and avoid regressions, let's add CONFIG_SPI option back.

Both define an AXI interface to the on-board Epiphany processor. Enable clocks FCLK0..FCLK3 for the Programmable Logic by default. Otherwise accessing, e.g., the ESYSRESET register freezes the board, as seen with the Epiphany SDK tools e-reset and e-hw-rev, using /dev/mem.
