Fix loop bailout off-by-one bugs reported by Juha Leppänen <juha_motorsportcom@luukku.com>. This second version incorporates comments from Russell King <linux@arm.linux.org.uk>. A new macro, 'omap_test_timeout', has been created, with cleaner code, and existing code has been converted to use it.

The code that reprograms the SDRC memory controller during CORE DVFS, mach-omap2/sram34xx.S:omap3_sram_configure_core_dpll(), does not ensure that all L3 initiators are prevented from accessing the SDRAM before modifying the SDRC AC timing and MR registers. This can cause memory to be corrupted or cause the SDRC to enter an unpredictable state. This patch places that code behind a Kconfig option, CONFIG_OMAP3_SDRC_AC_TIMING for now, and adds a note explaining what is going on. Ideally the code can be added back in once supporting code is present to ensure that other initiators aren't touching the SDRAM. At the very least, these registers should be reprogrammable during kernel init to deal with buggy bootloaders. Users who know that all other system initiators will not be touching the SDRAM can also re-enable this Kconfig option. This is a modification of a patch originally written by Rajendra Nayak <rnayak@ti.com> (the original is at http://patchwork.kernel.org/patch/51927/). Rather than removing the code completely, this patch just comments it out. Thanks to Benoît Cousson <b-cousson@ti.com> and Christophe Sucur <c-sucur@ti.com> for explaining the technical basis for this and for explaining what can be done to make this path work in future code. Thanks to Richard Woodruff <r-woodruff2@ti.com>, Nishanth Menon <nm@ti.com>, and Olof Johansson <olof@lixom.net> for their comments.

Avoid cluttering the Kconfig space with debug options that are rarely used. These can now be enabled and disabled by patching the "#undef DEBUG" in the source files with "#define DEBUG", conforming to the practice for the rest of the linux-omap code. Also, while we're here, some lines in plat-omap/Kconfig use sets of leading spaces when those lines should start with tabs. Convert most of them to use tabs.

The OMAP2 clock code currently #includes a large .h file full of static data structures. Instead, define the data in a .c file. Russell King <linux@arm.linux.org.uk> proposed this new arrangement: http://marc.info/?l=linux-omap&m=125967425908895&w=2 This patch also deals with most of the flagrant checkpatch violations. While here, separate the prcm_config data structures out into their own files, opp2xxx.h and opp24{2,3}0_data.c, and only build in the OPP tables for the target device. This should save some memory. In the long run, these prcm_config tables should be replaced with OPP code.

cpu_mask is reused in the OMAP2xxx clock code to match against both the CPU-specific rate flags (e.g., RATE_IN_2420) and the OMAP clkdev integration code CPU flags (e.g., CK_242X). This means that any patch that renumbers the CK_* macros, as the next patch does, will probably break. This patch separates the clkdev_omap and clksel_rate CPU type detection flags so the CK_* macros can be renumbered freely. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Similar to the previous patch, the APLL code relied on the presence of the static struct clks in its own namespace. The APLL code didn't use them for validation, however - it adjusted its own internal state depending on the struct clk * that called it. Now that static struct clks are leaving the clock24xx.c namespace, use a more durable method: split the omap2_clk_fixed_enable() function into omap2_clk_apll96_enable() and omap2_clk_apll54_enable(). They still share a disable function. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Some parts of the clock code took advantage of the fact that the statically allocated clock tree was in clock{,24xx,34xx}.c's local namespace to do some extra argument checks. These are overzealous and are more difficult to maintain when the clock tree is in a separate namespace, so, remove them. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used to allocate large continuous blocks of SDRAM or SRAM. The features VRAM manager has that are missing from dma_alloc_* functions are: - Support for OMAP2's SRAM - Allocate without ioremapping - Allocate at defined physical addresses - Allows larger VRAM area and larger allocations The upcoming DSS2 uses VRAM manager. VRAM area size can be defined in kernel config, board file or with kernel boot parameters. Board file definition overrides kernel config, and boot parameter overrides kernel config and board file.

The I2C-1 bus frequency on zoom2/zoom3/sdp3630 should be 2.4 MHz. The speed is limited by TWL5030/GAIA; a higher speed could lead to errors on the interface. The maximum I2C speed depends on the system clock for GAIA: 2.2 MHz (sys-clk = 19.2 MHz) 2.4 MHz (sys-clk = 26 MHz) 2.9 MHz (sys-clk = 38.4 MHz) For Zoom2/Zoom3/SDP3630 the system clock is 26Mhz and hence choose 2.4Mhz for I2C1 bus speed Signed-off-by: NVikram Pandita <vikram.pandita@ti.com> Signed-off-by: NTony Lindgren <tony@atomide.com>
