2009-06-19OMAP3 SRAM: convert SRAM code to use macros rather than magic numbersPaul Walmsley

2009-06-19OMAP3 clock/SDRC: program SDRC_MR register during SDRC clock changePaul Walmsley
Program the SDRC_MR_0 register as well during SDRC clock changes. This register allows selection of the memory CAS latency. Some SDRAM chips, such as the Qimonda HYB18M512160AF6, have a lower CAS latency at lower clock rates. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2009-06-19OMAP3 clock: add a short delay when lowering CORE clk ratePaul Walmsley
When changing the SDRAM clock from 166MHz to 83MHz via the CORE DPLL M2 divider, add a short delay before returning to SDRAM to allow the SDRC time to stabilize. Without this delay, the system is prone to random panics upon re-entering SDRAM. This time delay varies based on MPU frequency. At 500MHz MPU frequency at room temperature, 64 loops seems to work okay; so add another 32 loops for environmental and process variation. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2009-06-19OMAP3 clock: initialize SDRC timings at kernel startPaul Walmsley
On the OMAP3, initialize SDRC timings when the kernel boots. This ensures that the kernel is running with known, optimized SDRC timings, rather than whatever was configured by the bootloader. Signed-off-by: Paul Walmsley <paul@pwsan.com>
2009-06-19OMAP3 clock: remove wait for DPLL3 M2 clock to stabilizePaul Walmsley
The original CDP kernel that this code comes from waited for 0x800 loops after switching the CORE DPLL M2 divider. This does not appear to be necessary. Signed-off-by: Paul Walmsley <paul@pwsan.com>

2009-06-19[ARM] Add old Feroceon support to compressed/head.SJoonyoung Shim
This patch supports the cache handling for some old Feroceon cores for which the CPU ID is like 0x41159260. This is a complement to commit ab6d15d50637fc25ee941710b23fed09ceb28db3. Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Nicolas Pitre <nico@marvell.com>
2009-06-19[ARM] 5559/1: Limit the stack unwinding caused by a kthread exitCatalin Marinas
When a kthread function returns, it branches to do_exit(). However, the unwinding information isn't valid anymore and any stack trace caused by do_exit() may be incorrect. This patch adds a kernel_thread_exit() function and annotated with '.cantunwind' so that the unwinder stops when reaching it.

2009-06-19[ARM] 5558/1: Add extra checks to ARM unwinder to avoid tracing corrupt stacksCatalin Marinas
There are situations where the unwinder goes beyond stack boundaries and unwinds random data. This patch moves the stack boundaries check after the unwind_exec_insn() call and adds an extra check for possible infinite loops (like "mov pc, lr" with pc == lr). The patch also fixes a bug in the unwind instructions interpreter. The 0xb0 instruction can only set PC to LR if this wasn't already set by a previous instruction (this is used on exceptions taken while in kernel mode where svc_entry is annotated with ".save {r0 - pc}").

2009-06-16[ARM] GTA02/FreeRunner: Add machine definitionAndy Green
This patch introduces the Openmoko GTA02 machine definition. Much of the code is based on Harald Welte's work, although it has been largely rewritten several times. This is intended to be the minimum machine definition to boot and be able to run a rootfs from NAND on GTA02 / FreeRunner. It does not bring up the framebuffer / Glamo and lacks many other peripheral drivers from outside the SoC. But once we have this basis in mainline kernel, we will be able to introduce the other drivers and add them here.

2009-06-16[ARM] S3C64XX: Initial support for DVFSMark Brown
This patch provides initial support for CPU frequency scaling on the Samsung S3C ARM processors. Currently only S3C6410 processors are supported, though addition of another data table with supported clock rates should be sufficient to enable support for further CPUs. Use the regulator framework to provide optional support for DVFS in the S3C cpufreq driver. When a software controllable regulator is configured the driver will use it to lower the supply voltage when running at a lower frequency, giving improved power savings. When regulator support is disabled or no regulator can be obtained for VDDARM the driver will fall back to scaling only the frequency.

2009-06-16V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_linkGuennadi Liakhovetski
Currently pcm990 camera bus-width management functions request a GPIO and never free it again. With this approach the GPIO extender driver cannot be unloaded once camera drivers have been loaded, also unloading theb i2c-pxa bus driver produces errors, because the GPIO extender driver cannot unregister properly. Another problem is, that if camera drivers are once loaded before the GPIO extender driver, the platform code marks the GPIO unavailable and only a reboot helps to recover. Adding an explicit free_bus method and using it in mt9m001 and mt9v022 drivers fixes these problems.
