* ARM: davinci: add runtime PM support for clock managementKevin Hilman2012-07-011-0/+1
| | | | | | | | | | | | | | | | | Add runtime PM core support to davinci by using the pm_clk infrastructure of the PM core. When runtime PM is enabled, the davinci runtime PM implementation will use the pm_clk layer to enable/disable clocks on demand. When runtime PM is disabled, the pm_clk core will automatically enable clocks when the driver is bound and disable clocks when the driver is unbound. Cc: Mark A.

* davinci: add support for aemif timing configurationSekhar Nori2010-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to configure the AEMIF interface with supplied timing values. Since this capability is useful both from NOR and NAND flashes, it is provided as a new interface and in a file of its own. AEMIF timing configuration is required in cases: 1) Where the AEMIF clock rate can change at runtime (a side affect of cpu frequency change). 2) Where U-Boot does not support NAND/NOR but supports other media like SPI Flash or MMC/SD and thus does not care about setting up the AEMIF timing for kernel to use. 3) Where U-Boot just hasn't configured the timing values and cannot be upgraded because the box is already in the field. Since there is now a header file for AEMIF interface, the common (non-NAND specific) defines for AEMIF registers have been moved from nand.h into the newly created aemif.h Signed-off-by: Sekhar Nori <nsekhar@ti.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

* Davinci: tnetv107x initial gpio supportCyril Chemparathy2010-06-211-0/+1
| | | | | | | | | | | | | | | | This patch adds support for the tnetv107x gpio controller. Key differences between davinci and tnetv107x controllers: - register map - davinci's controller is organized into banks of 32 gpios, tnetv107x has a single space with arrays of registers for in, out, direction, etc. - davinci's controller has separate set/clear registers for output, tnetv107x has a single direct mapped register. This patch does not yet add gpio irq support on this controller. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* Davinci: tnetv107x soc supportCyril Chemparathy2010-06-211-0/+1
| | | | | | | | | | | | | | | | | | TNETV107X is a Texas Instruments SOC that shares a number of common features with the Davinci architecture. Some of the key differences between traditional Davincis and this new SOC are as follow: 1. The SOCs clock architecture includes a new spread-spectrum PLL. Some elements of the clock architecture are reused from Davinci (e.g. LPSC), but the PLL related code is overridden using existing interfaces in "struct clk". 2. The MMR layout on this SOC is substantially different from Davinci. Consequently, the fixed I/O map is a whole lot more convoluted (more so than DA8xx). The net impact here is that IO_ADDRESS() will not work on this SoC, and therefore all mappings have to be through ioremap().

* davinci: add CDCE949 support on DM6467 EVMNageswari Srinivasan2010-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch adds the CDCE949 reference oscillator to the davinci clock list. On the DM6467T EVM, the CDCE949 is responsible for generating the pixel clock for display. On the DM6467 EVM, this pixel clock was being obtained from an internal source. This is not possible on the DM6467T EVM because of the presence of a 33MHz oscillator. The TSIF module also requires the CDCE949 to generate the data clocks. The actual clock definitions will be added by patches adding support for DM6467T VPIF and TSIF. This patch mearly lays the foundation for that work.

* davinci: add power management supportSekhar Nori2010-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds core power management (suspend-to-RAM) support for DaVinci SoCs. The code depends on the the "deepsleep" feature to suspend the SoC and saves power by gating the input clock. The wakeup can be based on an external event as supported by the SoC. Assembly code (in sleep.S) is added to aid gating DDR2 clocks. Code doing this work should not be accessing DDR2. The assembly code is relocated to SRAM by the code in pm.c The support has been validated on DA850/OMAP-L138 only though the code is (hopefully) generic enough that other SoCs supporting deepsleep feature simply requires SoC specific code to start using this driver. Note that all the device drivers don't support suspend/resume still and are being worked on. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

* davinci: add CPU idle driverSekhar Nori2009-11-251-0/+1
| | | | | | | | | | | | | | | | | | | The patch adds support for DaVinci cpu idle driver. Two idle states are defined: 1. Wait for interrupt 2. Wait for interrupt and DDR self-refresh (or power down) Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467) while others support putting DDR in self-refresh and power down (eg DM35x, DA8xx). Putting DDR (or mDDR) in power down saves more power than self-refresh. The patch has been tested on DA850/OMAP-L138 EVM.

The EVM schematics are not available publicly yet; but should be available soon. A new defconfig for this board has been added mainly because the DA830/OMAP-L137 defconfig forces writethrough cache mode which is not required on DA850/OMAP-L138.

* davinci: da8xx: Add base DA830/OMAP-L137 SoC supportMark A. Greer2009-08-261-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The da830/omap l137 is a new SoC from TI that is similar to the davinci line. Since its so similar to davinci, put the support for the da830 in the same directory as the davinci code. There are differences, however. Some of those differences prevent support for davinci and da830 platforms to work in the same kernel binary. Those differences are: 1) Different physical address for RAM. This is relevant to Makefile.boot addresses and PHYS_OFFSET. The Makefile.boot issue isn't truly a kernel issue but it means u-boot won't work with a uImage including both architectures. The PHYS_OFFSET issue is addressed by the "Allow for runtime-determined PHYS_OFFSET" patch by Lennert Buytenhek but it hasn't been accepted yet. 2) Different uart addresses. This is only an issue for the 'addruart' assembly macro when CONFIG_DEBUG_LL is enabled. Since the code in that macro is called so early (e.g., by _error_p in kernel/head.S when the processor lookup fails), we can't determine what platform the kernel is running on at runtime to use the correct uart address. These areas have compile errors intentionally inserted to indicate to the builder they're doing something wrong. A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added to distinguish between a true davinci architecture and the da830 architecture. Note that the da830 currently has an issue with writeback data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be enabled when building a da830 kernel.

* davinci: add SRAM allocatorDavid Brownell2009-05-281-1/+1
| | | | | | | | | | | | | | | | | | | Provide a generic SRAM allocator using genalloc, and vaguely modeled after what AVR32 uses. This builds on top of the static CPU mapping set up in the previous patch, and returns DMA mappings as requested (if possible). Compared to its OMAP cousin, there's no current support for (currently non-existent) DaVinci power management code running in SRAM; and this has ways to deallocate, instead of being allocate-only. The initial user of this should probably be the audio code, because EDMA from DDR is subject to various dropouts on at least DM355 and DM6446 chips.

* davinci: Support JTAG ID register at any addressMark A. Greer2009-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The Davinci cpu_is_davinci_*() macros use the SoC part number and variant retrieved from the JTAG ID register to determine the type of cpu that the kernel is running on. Currently, the code to read the JTAG ID register assumes that the register is always at the same base address. This isn't true on some newer SoCs. To solve this, have the SoC-specific code set the JTAG ID register base address in soc_info structure and add a 'cpu_id' member to it. 'cpu_id' will be used by the cpu_is_davinci_*() macros to match the cpu id. Also move the info used to identify the cpu type into the SoC-specific code to keep all SoC-specific code together. The common code will read the JTAG ID register, search through an array of davinci_id structures to identify the cpu type. Once identified, it will set the 'cpu_id' member of the soc_info structure to the proper value and the cpu_is_davinci_*() macros will now work. Signed-off-by: Mark A.

* davinci: Encapsulate SoC-specific data in a structureMark A. Greer2009-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Create a structure to encapsulate SoC-specific information. This will assist in generalizing code so it can be used by different SoCs that have similar hardware but with minor differences such as having a different base address. The idea is that the code for each SoC fills out a structure with the correct information. The board-specific code then calls the SoC init routine which in turn will call a common init routine that makes a copy of the structure, maps in I/O regions, etc. After initialization, code can get a pointer to the structure by calling davinci_get_soc_info(). Eventually, the common init routine will make a copy of all of the data pointed to by the structure so the original data can be made __init_data. That way the data for SoC's that aren't being used won't consume memory for the entire life of the kernel. The structure will be extended in subsequent patches but initially, it holds the map_desc structure for any I/O regions the SoC/board wants statically mapped. Signed-off-by: Mark A.
