From ab90e6391bc3c86d052d954fe32c7526c6fcc947 Mon Sep 17 00:00:00 2001 From: Elaine Zhang Date: Tue, 2 May 2017 15:34:05 +0800 Subject: [PATCH] UPSTREAM: clk: rockchip: mark noc and some special clk as critical on rk3288 The atclk/dbg/jtag/hsic-xin12m/pclk_core clks no driver to handle them. But this clks need enable,so make it as ignore_unused for now. The ddrupctl0/ddrupctl1/publ0/publ1 clks no driver to handle them, Chip design requirements for these clock to always on, The pmu_hclk_otg0 is Chip design defect, must be always on, Signed-off-by: Elaine Zhang Signed-off-by: Heiko Stuebner (cherry picked from git.kernel.org mmind/linux-rockchip.git v4.13-clk/next commit 55bb6a633c33caf68ab470907ecf945289cb733d) Conflicts: drivers/clk/rockchip/clk-rk3288.c Change-Id: I6271a903deb9ca21b5e74fd2c1ad4cf69f7021e1 Signed-off-by: Elaine Zhang --- drivers/clk/rockchip/clk-rk3288.c | 19 +++++++++++++++---- 1 file changed, 15 insertions(+), 4 deletions(-) diff --git a/drivers/clk/rockchip/clk-rk3288.c b/drivers/clk/rockchip/clk-rk3288.c index 7140c84d81ec..5d9ec9c3feb0 100644 --- a/drivers/clk/rockchip/clk-rk3288.c +++ b/drivers/clk/rockchip/clk-rk3288.c @@ -291,13 +291,13 @@ static struct rockchip_clk_branch rk3288_clk_branches[] __initdata = { COMPOSITE_NOMUX(0, "aclk_core_mp", "armclk", CLK_IGNORE_UNUSED, RK3288_CLKSEL_CON(0), 4, 4, DFLAGS | CLK_DIVIDER_READ_ONLY, RK3288_CLKGATE_CON(12), 6, GFLAGS), - COMPOSITE_NOMUX(0, "atclk", "armclk", 0, + COMPOSITE_NOMUX(0, "atclk", "armclk", CLK_IGNORE_UNUSED, RK3288_CLKSEL_CON(37), 4, 5, DFLAGS | CLK_DIVIDER_READ_ONLY, RK3288_CLKGATE_CON(12), 7, GFLAGS), COMPOSITE_NOMUX(0, "pclk_dbg_pre", "armclk", CLK_IGNORE_UNUSED, RK3288_CLKSEL_CON(37), 9, 5, DFLAGS | CLK_DIVIDER_READ_ONLY, RK3288_CLKGATE_CON(12), 8, GFLAGS), - GATE(0, "pclk_dbg", "pclk_dbg_pre", 0, + GATE(0, "pclk_dbg", "pclk_dbg_pre", CLK_IGNORE_UNUSED, RK3288_CLKGATE_CON(12), 9, GFLAGS), GATE(0, "cs_dbg", "pclk_dbg_pre", CLK_IGNORE_UNUSED, RK3288_CLKGATE_CON(12), 10, GFLAGS), @@ -628,7 +628,7 @@ static struct rockchip_clk_branch rk3288_clk_branches[] __initdata = { INVERTER(SCLK_HSADC, "sclk_hsadc", "sclk_hsadc_out", RK3288_CLKSEL_CON(22), 7, IFLAGS), - GATE(0, "jtag", "ext_jtag", 0, + GATE(0, "jtag", "ext_jtag", CLK_IGNORE_UNUSED, RK3288_CLKGATE_CON(4), 14, GFLAGS), COMPOSITE_NODIV(SCLK_USBPHY480M_SRC, "usbphy480m_src", mux_usbphy480m_p, 0, @@ -637,7 +637,7 @@ static struct rockchip_clk_branch rk3288_clk_branches[] __initdata = { COMPOSITE_NODIV(SCLK_HSICPHY480M, "sclk_hsicphy480m", mux_hsicphy480m_p, 0, RK3288_CLKSEL_CON(29), 0, 2, MFLAGS, RK3288_CLKGATE_CON(3), 6, GFLAGS), - GATE(0, "hsicphy12m_xin12m", "xin12m", 0, + GATE(0, "hsicphy12m_xin12m", "xin12m", CLK_IGNORE_UNUSED, RK3288_CLKGATE_CON(13), 9, GFLAGS), DIV(0, "hsicphy12m_usbphy", "sclk_hsicphy480m", 0, RK3288_CLKSEL_CON(11), 8, 6, DFLAGS), @@ -809,9 +809,20 @@ static struct rockchip_clk_branch rk3288_clk_branches[] __initdata = { static const char *const rk3288_critical_clocks[] __initconst = { "aclk_cpu", "aclk_peri", + "aclk_peri_niu", + "aclk_vio0_niu", "aclk_vio1_niu", + "aclk_rga_niu", "hclk_peri", + "hclk_vio_niu", + "pclk_alive_niu", "pclk_pd_pmu", + "pclk_pmu_niu", + "pclk_core_niu", + "pclk_ddrupctl0", + "pclk_publ0", + "pclk_ddrupctl1", + "pclk_publ1", "pmu_hclk_otg0", }; -- 2.34.1
