From 7954dfaee386d45d6ec655e5153ad67edf311a56 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 26 Nov 2014 15:16:52 +0800 Subject: clk: sunxi: unify sun6i AHB1 clock with proper PLL6 pre-divider This patch unifies the sun6i AHB1 clock, originally supported with separate mux and divider clks. It also adds support for the pre-divider on the PLL6 input, thus allowing the clock to be muxed to PLL6 with proper clock rate calculation.

The only difference is wider mux register bits. As with earlier Allwinner SoCs, mmc module clocks are a special case of mod0 clocks, with phase controls for 2 child clocks, output and sample. This patch adds support for both.

There are four instances of the FAPLL on dm816x that each have three to seven child synthesizers. I've set up the FAPLL as a single fapll.c driver. Later on we could potentially have the PLL code generic. To do that, we would have to consider the following: 1. Setting the PLL to bypass mode also sets the child synthesizers into bypass mode. As the bypass rate can also be generated by the PLL in regular mode, there's no way for the child synthesizers to detect the bypass mode based on the parent clock rate. 2. The PLL registers control the power for each of the child syntheriser. Note that the clocks are currently still missing the set_rate implementation so things are still running based on the bootloader values. That's OK for now as most of the outputs have dividers and those can be set using the existing TI component clock code. I have verified that the extclk rates are correct for a few clocks, so adding the set_rate support should be fairly trivial later on.
