From d31ff5f7f3b142b8d1ebb3da89187c54cdf2bc71 Mon Sep 17 00:00:00 2001 From: "Damien.Horsley" Date: Wed, 26 Aug 2015 17:11:40 +0100 Subject: [PATCH] clk: pistachio: correct critical clock list Current critical clock list for pistachio enables only mips and sys clocks by default but there are also other clocks that are not claimed by anyone and needs to be enabled by default. This patch updates the critical clocks that need to be enabled by default. Add a separate struct to distinguish the critical clocks as listed: 1.) core clocks: a.) mips clock 2.) peripheral system clocks: a.) sys clock b.) sys_bus clock c.) DDR clock d.) ROM clock Fixes: b35d7c33419c("CLK: Pistachio: Register core clocks") Cc: # 4.1 Reviewed-by: Andrew Bresticker Signed-off-by: Ezequiel Garcia Signed-off-by: Damien.Horsley Signed-off-by: Govindraj Raja Signed-off-by: Stephen Boyd --- drivers/clk/pistachio/clk-pistachio.c | 19 ++++++++++++++----- 1 file changed, 14 insertions(+), 5 deletions(-) diff --git a/drivers/clk/pistachio/clk-pistachio.c b/drivers/clk/pistachio/clk-pistachio.c index 8c0fe8828f99..c4ceb5eaf46c 100644 --- a/drivers/clk/pistachio/clk-pistachio.c +++ b/drivers/clk/pistachio/clk-pistachio.c @@ -159,9 +159,15 @@ PNAME(mux_debug) = { "mips_pll_mux", "rpu_v_pll_mux", "wifi_pll_mux", "bt_pll_mux" }; static u32 mux_debug_idx[] = { 0x0, 0x1, 0x2, 0x4, 0x8, 0x10 }; -static unsigned int pistachio_critical_clks[] __initdata = { - CLK_MIPS, - CLK_PERIPH_SYS, +static unsigned int pistachio_critical_clks_core[] __initdata = { + CLK_MIPS +}; + +static unsigned int pistachio_critical_clks_sys[] __initdata = { + PERIPH_CLK_SYS, + PERIPH_CLK_SYS_BUS, + PERIPH_CLK_DDR, + PERIPH_CLK_ROM, }; static void __init pistachio_clk_init(struct device_node *np) @@ -193,8 +199,8 @@ static void __init pistachio_clk_init(struct device_node *np) pistachio_clk_register_provider(p); - pistachio_clk_force_enable(p, pistachio_critical_clks, - ARRAY_SIZE(pistachio_critical_clks)); + pistachio_clk_force_enable(p, pistachio_critical_clks_core, + ARRAY_SIZE(pistachio_critical_clks_core)); } CLK_OF_DECLARE(pistachio_clk, "img,pistachio-clk", pistachio_clk_init); @@ -261,6 +267,9 @@ static void __init pistachio_clk_periph_init(struct device_node *np) ARRAY_SIZE(pistachio_periph_gates)); pistachio_clk_register_provider(p); + + pistachio_clk_force_enable(p, pistachio_critical_clks_sys, + ARRAY_SIZE(pistachio_critical_clks_sys)); } CLK_OF_DECLARE(pistachio_clk_periph, "img,pistachio-clk-periph", pistachio_clk_periph_init); -- 2.39.5
