From 7d2129310b8c1f22850d56b1725447aef88d8b1f Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Tue, 4 Jun 2019 15:31:59 -0700 Subject: [PATCH] clk: rockchip: Remove 48 MHz PLL rate from rk3288 The 48 MHz PLL rate is not present in the downstream chromeos-3.14 tree. Looking at history, it was originally removed in ("CHROMIUM: clk: rockchip: expand more clocks support") with no explanation. Much of that patch was later reverted in ("CHROMIUM: clk: rockchip: Revert more questionable PLL rates"), but that patch left in the removal of 48 MHz. What I wrote in that patch: > Note that the original change also removed the rate (48000000, 1, > 64, 32) from the table. I have no idea why that was squashed in > there, but that rate was invalid anyway (it appears to have an out > of bounds NO). I'm not putting that rate in. Reading the TRM I see that NO is defined as - NO: 1, 2-16 (even only) ...and furthermore only 4 bits are assigned for NO-1, which means that the highest NO we could even represent is 16.
