2009-10-20omap: headers: Create headers necessary for compile under mach-omap1 and ↵Tony Lindgren30-0/+100
mach-omap2 Create the headers needed for compiling under mach-omap1/include/mach and mach-omap2/include/mach. This was done with the following script: #!/bin/bash mach_files="clkdev.h gpio.h hardware.h io.h irqs.h memory.h \ smp.h system.h timex.h uncompress.h vmalloc.h" omaps="mach-omap1 mach-omap2" mach_dir_old="arch/arm/plat-omap/include/mach" plat_dir_new="arch/arm/plat-omap/include/plat" mkdir -p $plat_dir_new git add $plat_dir_new for dir in $omaps; do mach_dir_new="arch/arm/$dir/include/mach" for header in $mach_files; do file="$mach_dir_new/$header" if [ ! -f $file ]; then echo -ne "/*\n * $file\n */\n\n#include <plat/$header>\n" > $file git add $file if [ ! -f $plat_dir_new/$header ]; then git mv $mach_dir_old/$header $plat_dir_new/$header fi fi done done Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-10-20omap: Split vmalloc.h for mach-omap1 and mach-omap2Tony Lindgren2-5/+21
Earlier patch "omap: Remap L3, L4 to get more kernel io address space" changed the VMALLOC_END. However, this change causes problems on mach-omap1: BUG: mapping for 0xe0000000 at 0xe0000000 overlaps vmalloc space BUG: mapping for 0xe1000000 at 0xe1000000 overlaps vmalloc space Fix this by creating separate vmalloc.h files for mach-omap1 and mach-omap2.

2009-10-20omap: Remap L3, L4 to get more kernel io address spaceSantosh Shilimkar2-40/+64
This patch remap L3 and L4 io space to get more kernel address space. With this patch, 512 MB of IO space is reclaimed. Some more combinations are possible but to make it uniform across OMAP24XX, OMAP34XX and OMAP4430, these io combinations are chosen Once this is reviewed and tested sufficiently, a documentation entry can be created to ease up reading and debugging.

2009-10-20omap: Split OMAP2_IO_ADDRESS to L3 and L4Santosh Shilimkar13-66/+75
This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and OMAP2_L4_IO_ADDRESS to reclaim more IO space. The omap_read*() and omap_write*() functions will work only over L4 address space. Current omap kernel stack uses these functions only to access registers over L4 io address space Note that these macros should only be used when ioremap does not work.

clock24xx.c is missing a omap2_init_clk_clkdm() in its omap2_clk_init() function. Among other bad effects, this causes the OMAP hwmod layer to oops on boot.

2009-10-15OMAP: Fix race condition with autodepsKalle Jokiniemi1-30/+44
There is a possible race condition in clockdomain code handling hw supported idle transitions. When multiple autodeps dependencies are being added or removed, a transition of still remaining dependent powerdomain can result in false readings of the state counter. This is especially fatal for off mode state counter, as it could result in a driver not noticing a context loss. Fixed by disabling hw supported state transitions when autodeps are being changed.

2009-10-12ARM: force dcache flush if dcache_dirty bit setNitin Gupta1-6/+3
On ARM, update_mmu_cache() does dcache flush for a page only if it has a kernel mapping (page_mapping(page) != NULL). The correct behavior would be to force the flush based on dcache_dirty bit only. One of the cases where present logic would be a problem is when a RAM based block device[1] is used as a swap disk. In this case, we would have in-memory data corruption as shown in steps below: do_swap_page() { - Allocate a new page (if not already in swap cache) - Issue read from swap disk - Block driver issues flush_dcache_page() - flush_dcache_page() simply sets PG_dcache_dirty bit and does not actually issue a flush since this page has no user space mapping yet. - Now, if swap disk is almost full, this newly read page is removed from swap cache and corrsponding swap slot is freed. - Map this page anonymously in user space. - update_mmu_cache() - Since this page does not have kernel mapping (its not in page/swap cache and is mapped anonymously), it does not issue dcache flush even if dcache_dirty bit is set by flush_dcache_page() above. <user now gets stale data since dcache was never flushed> } Same problem exists on mips too. [1] example: - brd (RAM based block device) - ramzswap (RAM based compressed swap device) Signed-off-by: Nitin Gupta <ngupta@vflare.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-10-10ARM: 5756/1: ep93xx: introduce clk parentHartley Sweeten1-47/+119
The clock generation system in the ep93xx uses two external oscillator's and two internal PLLs to derive all the internal clocks. Many of these internal clocks can be stopped to save power. This introduces a "parent" hierarchy for the clocks so that the users count can be correctly tracked for power management. The "parent" for the video clock can either be one of the PLL outputs or the external oscillator. In order to correctly track the "parent" for the video clock calc_clk_div() needed to be modified. It now returns an error code if the desired rate cannot be generated.

2009-10-10ARM: 5754/1: ep93xx: update i2c supportHartley Sweeten4-16/+51
Update the ep93xx i2c support: 1) The platform init code passes the configuration data for the i2c-gpio driver. This allows any gpio pin do be used for the sda and scl pins. It also allows the platform to specify the udelay and timeout. 2) Program the gpio configuration register to enable/disable the open drain drivers. Note that this really only works if the sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and EP93XX_GPIO_LINE_EECLK. 3) Update the edb93xx.c platform init to use the new support.
