ARM: dts: dra7xx-clocks: Fix the l3 and l4 clock rates Without the patch: /debug/.../dpll_core_x2_ck/dpll_core_h12x2_ck # cat clk_rate 532000000 /debug/.../dpll_core_x2_ck/dpll_core_h12x2_ck/l3_iclk_div # cat clk_rate 532000000 /debug/.../dpll_core_x2_ck/dpll_core_h12x2_ck/l3_iclk_div/l4_root_clk_div # cat clk_rate 532000000 With the patch: /debug/.../dpll_core_x2_ck/dpll_core_h12x2_ck # cat clk_rate 532000000 /debug/.../dpll_core_x2_ck/dpll_core_h12x2_ck/l3_iclk_div # cat clk_rate 266000000 /debug/.../dpll_core_x2_ck/dpll_core_h12x2_ck/l3_iclk_div/l4_root_clk_div # cat clk_rate 133000000 The l3 clock derived from core DPLL is actually a divider clock, with the default divider set to 2. l4 then derived from l3 is a fixed factor clock, but the fixed divider is 2 and not 1. Which means the l3 clock is half of core DPLLs h12x2 and l4 is half of l3 (as seen with this patch) Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Tero Kristo <t-kristo@ti.com>
