X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=62d206dc3126914f187cfb72e8a7c6cf84c19b7c;p=project%2Fbcm63xx%2Fu-boot.git armv7: hw_data: change clock divider setting. Clock requirement for qspi clk is 192 Mhz. According to the below formulae, f dpll = f ref * 2 * m /(n + 1) clockoutx2_Hmn = f dpll / (hmn+ 1) fref = 20 Mhz, m = 96, n = 4 gives f dpll = 768 Mhz For clockoutx2_Hmn to be 768, hmn + 1 should be 4.
