From ced98628bf6ca7705b2d06df9c71a80cd1cd49bb Mon Sep 17 00:00:00 2001 From: Cyril Chemparathy Date: Wed, 20 Oct 2010 17:49:57 -0400 Subject: davinci: minor tnetv107x clock tree fixes This patch applies the following modifications to the tnetv107x clock tree: - reparent tnetv107x usb clocks to usbss - mark timer1 as always enabled - enable set_rate on pll divider output clocks - adjust tnetv107x tsc sysclk rate lower to fix invalid reset defaults Signed-off-by: Cyril Chemparathy Signed-off-by: Kevin Hilman --- arch/arm/mach-davinci/tnetv107x.c | 23 ++++++++++++----------- 1 file changed, 12 insertions(+), 11 deletions(-) (limited to 'arch/arm/mach-davinci/tnetv107x.c') diff --git a/arch/arm/mach-davinci/tnetv107x.c b/arch/arm/mach-davinci/tnetv107x.c index daeae06..6fcdece 100644 --- a/arch/arm/mach-davinci/tnetv107x.c +++ b/arch/arm/mach-davinci/tnetv107x.c @@ -131,12 +131,13 @@ define_pll_clk(tdm, 1, 0x0ff, 0x200); define_pll_clk(eth, 2, 0x0ff, 0x400); /* Level 2 - divided outputs from the PLLs */ -#define define_pll_div_clk(pll, cname, div) \ - static struct clk pll##_##cname##_clk = { \ - .name = #pll "_" #cname "_clk",\ - .parent = &pll_##pll##_clk, \ - .flags = CLK_PLL, \ - .div_reg = PLLDIV##div, \ +#define define_pll_div_clk(pll, cname, div) \ + static struct clk pll##_##cname##_clk = { \ + .name = #pll "_" #cname "_clk", \ + .parent = &pll_##pll##_clk, \ + .flags = CLK_PLL, \ + .div_reg = PLLDIV##div, \ + .set_rate = davinci_set_sysclk_rate, \ } define_pll_div_clk(sys, arm1176, 1); @@ -192,6 +193,7 @@ lpsc_clk_enabled(system, sys_half_clk, SYSTEM); lpsc_clk_enabled(ddr2_vrst, sys_ddr_clk, DDR2_EMIF1_VRST); lpsc_clk_enabled(ddr2_vctl_rst, sys_ddr_clk, DDR2_EMIF2_VCTL_RST); lpsc_clk_enabled(wdt_arm, sys_half_clk, WDT_ARM); +lpsc_clk_enabled(timer1, sys_half_clk, TIMER1); lpsc_clk(mbx_lite, sys_arm1176_clk, MBX_LITE); lpsc_clk(ethss, eth_125mhz_clk, ETHSS); @@ -205,16 +207,15 @@ lpsc_clk(mdio, sys_half_clk, MDIO); lpsc_clk(sdio0, sys_half_clk, SDIO0); lpsc_clk(sdio1, sys_half_clk, SDIO1); lpsc_clk(timer0, sys_half_clk, TIMER0); -lpsc_clk(timer1, sys_half_clk, TIMER1); lpsc_clk(wdt_dsp, sys_half_clk, WDT_DSP); lpsc_clk(ssp, sys_half_clk, SSP); lpsc_clk(tdm0, tdm_0_clk, TDM0); lpsc_clk(tdm1, tdm_1_clk, TDM1); lpsc_clk(vlynq, sys_vlynq_ref_clk, VLYNQ); lpsc_clk(mcdma, sys_half_clk, MCDMA); -lpsc_clk(usb0, sys_half_clk, USB0); -lpsc_clk(usb1, sys_half_clk, USB1); lpsc_clk(usbss, sys_half_clk, USBSS); +lpsc_clk(usb0, clk_usbss, USB0); +lpsc_clk(usb1, clk_usbss, USB1); lpsc_clk(ethss_rgmii, eth_250mhz_clk, ETHSS_RGMII); lpsc_clk(imcop, sys_dsp_clk, IMCOP); lpsc_clk(spare, sys_half_clk, SPARE); @@ -281,7 +282,9 @@ static struct clk_lookup clks[] = { CLK(NULL, "clk_tdm0", &clk_tdm0), CLK(NULL, "clk_vlynq", &clk_vlynq), CLK(NULL, "clk_mcdma", &clk_mcdma), + CLK(NULL, "clk_usbss", &clk_usbss), CLK(NULL, "clk_usb0", &clk_usb0), + CLK(NULL, "clk_usb1", &clk_usb1), CLK(NULL, "clk_tdm1", &clk_tdm1), CLK(NULL, "clk_debugss", &clk_debugss), CLK(NULL, "clk_ethss_rgmii", &clk_ethss_rgmii), @@ -289,8 +292,6 @@ static struct clk_lookup clks[] = { CLK(NULL, "clk_imcop", &clk_imcop), CLK(NULL, "clk_spare", &clk_spare), CLK("davinci_mmc.1", NULL, &clk_sdio1), - CLK(NULL, "clk_usb1", &clk_usb1), - CLK(NULL, "clk_usbss", &clk_usbss), CLK(NULL, "clk_ddr2_vrst", &clk_ddr2_vrst), CLK(NULL, "clk_ddr2_vctl_rst", &clk_ddr2_vctl_rst), CLK(NULL, NULL, NULL), -- cgit v1.1
