Hi Manju, You have got a wrong address for linux-arm-kernel ML.
The right address is: linux-arm-ker...@lists.infradead.org Also, I think you need to subscribe to this list for your messages to get posted automatically. Subscription information is available here: http://lists.infradead.org/mailman/listinfo/linux-arm-kernel You can check that your patches are actually reaching ARM linux mailing list by checking the archives here: http://marc.info/?l=linux-arm-kernel On Tue, Jan 18, 2011 at 19:09:07, Hadli, Manjunath wrote: > Implemented a common and single mapping for DAVINCI_SYSTEM_MODULE_BASE > to be used by all davinci platforms. > > Signed-off-by: Manjunath Hadli <manjunath.ha...@ti.com> > Acked-by: Muralidharan Karicheri <m-kariche...@ti.com> > Acked-by: Hans Verkuil <hverk...@xs4all.nl> > --- > arch/arm/mach-davinci/common.c | 4 +++- > arch/arm/mach-davinci/devices.c | 10 ++++------ > arch/arm/mach-davinci/include/mach/hardware.h | 5 +++++ > 3 files changed, 12 insertions(+), 7 deletions(-) > > diff --git a/arch/arm/mach-davinci/common.c b/arch/arm/mach-davinci/common.c > index 1d25573..949e615 100644 > --- a/arch/arm/mach-davinci/common.c > +++ b/arch/arm/mach-davinci/common.c > @@ -111,7 +111,9 @@ void __init davinci_common_init(struct davinci_soc_info > *soc_info) > if (ret != 0) > goto err; > } > - > + davinci_sysmodbase = ioremap_nocache(DAVINCI_SYSTEM_MODULE_BASE, 0x800); > + if (!davinci_sysmodbase) > + goto err; This is actually not the right place to do this. davinci_common_init() is called for all 7 supported SoCs. This system module base address definitely not valid on the two DA8x SoCs. I suspect it is not valid on TNETV as well. That makes this call unnecessary on 3 of the 7 supported SoCs. I think the original approach of mapping it for each SoC that needed it was fine. > return; > > err: > diff --git a/arch/arm/mach-davinci/devices.c b/arch/arm/mach-davinci/devices.c > index 22ebc64..2bff2d6 100644 > --- a/arch/arm/mach-davinci/devices.c > +++ b/arch/arm/mach-davinci/devices.c > @@ -33,6 +33,8 @@ > #define DM365_MMCSD0_BASE 0x01D11000 > #define DM365_MMCSD1_BASE 0x01D00000 > > +void __iomem *davinci_sysmodbase; > + > static struct resource i2c_resources[] = { > { > .start = DAVINCI_I2C_BASE, > @@ -209,9 +211,7 @@ void __init davinci_setup_mmc(int module, struct > davinci_mmc_config *config) > davinci_cfg_reg(DM355_SD1_DATA2); > davinci_cfg_reg(DM355_SD1_DATA3); > } else if (cpu_is_davinci_dm365()) { > - void __iomem *pupdctl1 = > - IO_ADDRESS(DAVINCI_SYSTEM_MODULE_BASE + 0x7c); > - > + void __iomem *pupdctl1 = DAVINCI_SYSMODULE_VIRT(0x7c); > /* Configure pull down control */ > __raw_writel((__raw_readl(pupdctl1) & ~0xfc0), > pupdctl1); > @@ -243,9 +243,7 @@ void __init davinci_setup_mmc(int module, struct > davinci_mmc_config *config) > mmcsd0_resources[2].start = IRQ_DM365_SDIOINT0; > } else if (cpu_is_davinci_dm644x()) { > /* REVISIT: should this be in board-init code? */ > - void __iomem *base = > - IO_ADDRESS(DAVINCI_SYSTEM_MODULE_BASE); > - > + void __iomem *base = DAVINCI_SYSMODULE_VIRT(0); Please use DAVINCI_SYSMODULE_VIRT(DM64XX_VDD3P3V_PWDN) instead. > /* Power-on 3.3V IO cells */ > __raw_writel(0, base + DM64XX_VDD3P3V_PWDN); > /*Set up the pull regiter for MMC */ > diff --git a/arch/arm/mach-davinci/include/mach/hardware.h > b/arch/arm/mach-davinci/include/mach/hardware.h > index c45ba1f..5a105c4 100644 > --- a/arch/arm/mach-davinci/include/mach/hardware.h > +++ b/arch/arm/mach-davinci/include/mach/hardware.h > @@ -24,6 +24,11 @@ > /* System control register offsets */ > #define DM64XX_VDD3P3V_PWDN 0x48 > > +#ifndef __ASSEMBLER__ > + extern void __iomem *davinci_sysmodbase; > + #define DAVINCI_SYSMODULE_VIRT(x) (davinci_sysmodbase+(x)) Indenting the #defines is not required. Also, this will need to be placed in individual <soc>.h file. The currently defined DAVINCI_SYSTEM_MODULE_BASE and DM64XX_VDD3P3V_PWDN also violate the guidance provided in comments just before those defines. They should be moved to <soc>.h files too.
