The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted. Also clean up the #includes since we are adding some here. Signed-off-by: David Lechner --- v10 changes: - fix copy/paste error s/dm355/dm644x/ v9 changes: - register PLL1 and PSC in dm644x_init_time() instead of as platform device so that we get the correct timer0 clock for davinci_timer_init() - Fixed size of PLL memory block v8 changes: - none v7 changes: - add clock platform device declarations - register platform devices instead of registering clocks directly - add davinci prefix to commit description v6 changes: - add blank lines between function calls arch/arm/mach-davinci/board-dm644x-evm.c | 2 + arch/arm/mach-davinci/board-neuros-osd2.c | 2 + arch/arm/mach-davinci/board-sffsdr.c | 2 + arch/arm/mach-davinci/davinci.h | 1 + arch/arm/mach-davinci/dm644x.c | 64 +++++++++++++++++++---- 5 files changed, 62 insertions(+), 9 deletions(-) diff --git a/arch/arm/mach-davinci/board-dm644x-evm.c b/arch/arm/mach-davinci/board-dm644x-evm.c index 48436f74fd71..738e443ab15f 100644 --- a/arch/arm/mach-davinci/board-dm644x-evm.c +++ b/arch/arm/mach-davinci/board-dm644x-evm.c @@ -773,6 +773,8 @@ static __init void davinci_evm_init(void) struct clk *aemif_clk; struct davinci_soc_info *soc_info = &davinci_soc_info; + dm644x_register_clocks(); + dm644x_init_devices(); ret = dm644x_gpio_register(); diff --git a/arch/arm/mach-davinci/board-neuros-osd2.c b/arch/arm/mach-davinci/board-neuros-osd2.c index 25ad9b0612be..353f9e5a1454 100644 --- a/arch/arm/mach-davinci/board-neuros-osd2.c +++ b/arch/arm/mach-davinci/board-neuros-osd2.c @@ -175,6 +175,8 @@ static __init void davinci_ntosd2_init(void) struct clk *aemif_clk; struct davinci_soc_info *soc_info = &davinci_soc_info; + dm644x_register_clocks(); + dm644x_init_devices(); ret = dm644x_gpio_register(); diff --git a/arch/arm/mach-davinci/board-sffsdr.c b/arch/arm/mach-davinci/board-sffsdr.c index e7c1728b0833..792bb84d5011 100644 --- a/arch/arm/mach-davinci/board-sffsdr.c +++ b/arch/arm/mach-davinci/board-sffsdr.c @@ -134,6 +134,8 @@ static __init void davinci_sffsdr_init(void) { struct davinci_soc_info *soc_info = &davinci_soc_info; + dm644x_register_clocks(); + dm644x_init_devices(); platform_add_devices(davinci_sffsdr_devices, diff --git a/arch/arm/mach-davinci/davinci.h b/arch/arm/mach-davinci/davinci.h index a799b5266d4b..16aca5853ab2 100644 --- a/arch/arm/mach-davinci/davinci.h +++ b/arch/arm/mach-davinci/davinci.h @@ -108,6 +108,7 @@ int dm365_gpio_register(void); void dm644x_init(void); void dm644x_init_devices(void); void dm644x_init_time(void); +void dm644x_register_clocks(void); void dm644x_init_asp(void); int dm644x_init_video(struct vpfe_config *, struct vpbe_config *); int dm644x_gpio_register(void); diff --git a/arch/arm/mach-davinci/dm644x.c b/arch/arm/mach-davinci/dm644x.c index 708df0ed8554..c3cd27c6cd70 100644 --- a/arch/arm/mach-davinci/dm644x.c +++ b/arch/arm/mach-davinci/dm644x.c @@ -8,28 +8,34 @@ * is licensed "as is" without any warranty of any kind, whether express * or implied. */ -#include -#include -#include + +#include +#include +#include #include -#include +#include #include #include +#include +#include #include +#include #include #include -#include "psc.h" #include -#include #include -#include +#include +#include "asp.h" #include "davinci.h" -#include "clock.h" #include "mux.h" -#include "asp.h" + +#ifndef CONFIG_COMMON_CLK +#include "clock.h" +#include "psc.h" +#endif /* * Device specific clocks @@ -43,6 +49,7 @@ #define DM644X_EMAC_CNTRL_RAM_OFFSET 0x2000 #define DM644X_EMAC_CNTRL_RAM_SIZE 0x2000 +#ifndef CONFIG_COMMON_CLK static struct pll_data pll1_data = { .num = 1, .phys_base = DAVINCI_PLL1_BASE, @@ -326,6 +333,7 @@ static struct clk_lookup dm644x_clks[] = { CLK("davinci-wdt", NULL, &timer2_clk), CLK(NULL, NULL, NULL), }; +#endif static struct emac_platform_data dm644x_emac_pdata = { .ctrl_reg_offset = DM644X_EMAC_CNTRL_OFFSET, @@ -934,8 +942,46 @@ void __init dm644x_init(void) void __init dm644x_init_time(void) { +#ifdef CONFIG_COMMON_CLK + void __iomem *pll1, *psc; + struct clk *clk; + + clk_register_fixed_rate(NULL, "ref_clk", NULL, 0, DM644X_REF_FREQ); + + pll1 = ioremap(DAVINCI_PLL1_BASE, SZ_1K); + dm644x_pll1_init(NULL, pll1, NULL); + + psc = ioremap(DAVINCI_PWR_SLEEP_CNTRL_BASE, SZ_4K); + dm644x_psc_init(NULL, psc); + + clk = clk_get(NULL, "timer0"); + + davinci_timer_init(clk); +#else davinci_clk_init(dm644x_clks); davinci_timer_init(&timer0_clk); +#endif +} + +static struct resource dm644x_pll2_resources[] = { + { + .start = DAVINCI_PLL2_BASE, + .end = DAVINCI_PLL2_BASE + SZ_1K - 1, + .flags = IORESOURCE_MEM, + }, +}; + +static struct platform_device dm644x_pll2_device = { + .name = "dm644x-pll2", + .id = -1, + .resource = dm644x_pll2_resources, + .num_resources = ARRAY_SIZE(dm644x_pll2_resources), +}; + +void __init dm644x_register_clocks(void) +{ + /* PLL1 and PSC are registered in dm644x_init_time() */ + platform_device_register(&dm644x_pll2_device); } int __init dm644x_init_video(struct vpfe_config *vpfe_cfg,
