-Subject: [PATCH 245/247] clk: at91: sama7g5: remove prescaler part of master
- clock
-
-On SAMA7G5 the prescaler part of master clock has been implemented as a
-changeable one. Everytime the prescaler is changed the PMC_SR.MCKRDY bit
-must be polled. Value 1 for PMC_SR.MCKRDY means the prescaler update is
-done. Driver polls for this bit until it becomes 1. On SAMA7G5 it has
-been discovered that in some conditions the PMC_SR.MCKRDY is not rising
-but the rate it provides it's stable. The workaround is to add a timeout
-when polling for PMC_SR.MCKRDY. At the moment, for SAMA7G5, the prescaler
-will be removed from Linux clock tree as all the frequencies for CPU could
-be obtained from PLL and also there will be less overhead when changing
-frequency via DVFS.
