From 59b479e0985f0b795d68331d6443a7f89c47768d Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 27 Jan 2011 16:39:40 -0800 Subject: omap: Start using CONFIG_SOC_OMAP We want to have just CONFIG_ARCH_OMAP2, 3 and 4. The rest are nowadays just subcategories of these. Search and replace the following: ARCH_OMAP2420 SOC_OMAP2420 ARCH_OMAP2430 SOC_OMAP2430 ARCH_OMAP3430 SOC_OMAP3430 No functional changes.

This means, both cpu_is_omap34xx() and cpu_is_ti816x() checks return success on TI816X. A kernel config option CONFIG_SOC_OMAPTI816X is added under OMAP3 to include support for TI816X build.

Changes involves: 1) Removing all base address macro defines. 2) Using omap-device layer to register device and utilizing data from hwmod data file for base address, dma channel number, Irq_number, device attribute(number of chipselect). 3) Appending base address with pdata reg_offset for omap4 boards. For omap4 all regs used in driver deviate with reg_offset_macros defined with an value of 0x100. So pass this offset through pdata and append the same to base address retrieved from hwmod data file and we are not mapping *_HL_* regs which are not used in driver.

Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz). ES2.2 additionally has a couple of power management fixes (to reduce leakage), an I2C1 SDA line state fix, and a floating point write corruption fix (cortex erratum). Even though the current mainline support doesn't need to distinguish between ES2.X versions, it's still useful to know the correct silicon rev when issues are reported. Moreover, these id checks can be used by power management code that selects suitable OPPs considering the memory speed limitation on ES2.0.

This patch generates the hwmod database for Display Sub System applicable for OMAP3430 and OMAP36xx. DSS is also considered as an IP as DISPC, RFBI and named as dss_core. For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in each IP. This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also the firewall regions are different between 3430es1 and later.

Support such functionality by adding two new function pointer allow_idle and deny_idle in the clkops structure. These function pointers can be populated for any clock node which supports hardware level autogating. Also add 2 new functions (omap_clk_enable_autoidle_all and omap_clk_disable_autoidle_all) which can be called from architecture specific PM core code, if hardware level autogating (for all supported clock nodes) is to be enabled or disabled.

The one on the OMAP2420 is closer to that on OMAP1 chips. Currently, the n8x0 is the only OMAP2420 platform supported in mainline which registers the MMC controller. Upcoming changes to register the controllers using hwmod data are potentially invasive. To reduce the risk, separate out the 2420 controller registration from the common init function and update its only user. Also seperating out mux settings for OMAP2420.

Removing all base address macro defines except keeping one for OMAP2420 and adapting only hsmmc device registration and driver to hwmod framework. Changes involves: 1) Remove controller reset in devices.c which is taken care of by hwmod framework. 2) Using omap-device layer to register device and utilizing data from hwmod data file for base address, dma channel number, Irq_number, device attribute. 3) Update the driver to use dev_attr to find whether controller supports dual volt cards Signed-off-by: Paul Walmsley Signed-off-by: Kishore Kadiyala Reviewed-by: Balaji T K Cc: Benoit Cousson CC: Kevin Hilman Cc: Tony Lindgren Signed-off-by: Tony Lindgren --- arch/arm/mach-omap2/devices.c | 168 ----------------- arch/arm/mach-omap2/hsmmc.c | 346 +++++++++++++++++++--------------- arch/arm/plat-omap/include/plat/mmc.h | 20 +- drivers/mmc/host/omap_hsmmc.c | 4 +- 4 files changed, 200 insertions(+), 338 deletions(-) (limited to 'arch/arm/plat-omap/include') diff --git a/arch/arm/mach-omap2/devices.c b/arch/arm/mach-omap2/devices.c index 2f4a598ba67e..31632ac1ca7c 100644 --- a/arch/arm/mach-omap2/devices.c +++ b/arch/arm/mach-omap2/devices.c @@ -544,112 +544,6 @@ static inline void omap_init_aes(void) { } /*-------------------------------------------------------------------------*/ -#if defined(CONFIG_ARCH_OMAP3) || defined(CONFIG_ARCH_OMAP4) - -#define MMCHS_SYSCONFIG 0x0010 -#define MMCHS_SYSCONFIG_SWRESET (1 << 1) -#define MMCHS_SYSSTATUS 0x0014 -#define MMCHS_SYSSTATUS_RESETDONE (1 << 0) - -static struct platform_device dummy_pdev = { - .dev = { - .bus = &platform_bus_type, - }, -}; - -/** - * omap_hsmmc_reset() - Full reset of each HS-MMC controller - * - * Ensure that each MMC controller is fully reset.

charset=UTF-8 Content-Transfer-Encoding: 8bit There's no reason for this header file to be in plat-omap/include/plat/smartreflex.h. The hardware devices are in OMAP2+ SoCs only. Leaving this header file in plat-omap causes problems due to cross-dependencies with other header files that should live in mach-omap2/. Thanks to Benoît Cousson for suggesting the removal of the smartreflex.h include from the OMAP3xxx hwmod data.

As far as I know, this code is never used, since it's been more important for callers of the DPLL round_rate()/set_rate() functions to obtain an exact rate than it is to save a relatively small amount of power.

To avoid such issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now come from the user throught 'flags' parameter when mapping memory. As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON can be removed. The driver will now check internally if IOVMF_DA_FIXED is set or not.
