* ARM: OMAP2+: PRM: create PRM reset source API for the watchdog timer driverPaul Walmsley2012-10-2111-4/+306
| | | | | | | | | | | | | | | | | | The OMAP watchdog timer driver needs to determine what caused the SoC to reset for its GETBOOTSTATUS ioctl. So, define a set of standard reset sources across OMAP SoCs. For OMAP2xxx, 3xxx, and 4xxx SoCs, define mappings from the SoC-specific reset source register bits to the standardized reset source IDs. Create SoC-specific PRM functions that read the appropriate per-SoC register and use the mapping to return the standardized reset bits. Register the SoC-specific PRM functions with the common PRM code via prm_register(). Create a function in the common PRM code, prm_read_reset_sources(), that calls the SoC-specific function, registered during boot. This patch does not yet handle some SoCs, such as AM33xx. Those SoCs were not handled by the code this will replace. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* ARM: OMAP1: create read_reset_sources() function (for initial use by watchdog)Paul Walmsley2012-10-212-0/+40
| | | | | | | | | | | | | | | | | | | On OMAP1, the existing OMAP watchdog driver reads a register directly from a non-watchdog IP block. It also does not convert the register's contents into the standard WDIOF_* bits expected from the GETBOOTSTATUS ioctl(). To move towards fixing these problems, create an function in arch/arm/mach-omap1 to return the reset source data. A subsequent patch will provide this function to the watchdog driver via platform_data. In the long term, the best approach would be to move this function to a new OMAP1 driver that handles access to the OMAP1 Clock Generation and Reset Management IP block. Then no platform_data would be needed. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* ARM: OMAP2+: CM: prepare for use of cm_ll_data function pointersPaul Walmsley2012-10-213-1/+84
| | | | | | | | | | | | | | | | | There are several CM operations which behave similarly across OMAP2+ SoCs, but which have slight differences in their underlying implementations. This patch creates the support code for this function pointer registration process. No function pointers are included yet, but a subsequent patch will create these for the module IDLEST registers. This patch allows other code to use CM-provided data and operations without needing to know which SoC is currently in use. A further description of the concept is provided in the patch entitled "ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointers". Signed-off-by: Paul Walmsley <paul@pwsan.com>
* ARM: OMAP2+: PRM: prepare for use of prm_ll_data function pointersPaul Walmsley2012-10-212-0/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are several PRM operations which behave similarly across OMAP2+ SoCs, but which have slight differences in their underlying implementations. For example, to fetch the SoC's last reset sources, different registers are read across OMAP2xxx, 3xxx, and 44xx, and different bits are used on each SoC. But the information returned is so similar that a single, common interface for drivers is useful. This patch creates the support code for this function pointer registration process. No function pointers are included yet, but a subsequent patch will create one for the reset source API. To illustrate the end goal with the above reset source example, each per-SoC driver will use its own low-level implementation function -- e.g., prm2xxx.c would contain omap2xxx_prm_read_reset_sources(). This function would read the appropriate register and remap the register bits to a standard set of reset source bits. When the prm2xxx.c driver is loaded, it would register this function with the common PRM driver, prm.c. prm.c would then export a common function, omap_prm_read_reset_sources(). Calling it would call through to the function pointer for the currently-registered SoC PRM driver. This will allow other drivers to use PRM-provided data and operations without needing to know which SoC is currently in use. Signed-off-by: Paul Walmsley <paul@pwsan.com>
* ARM: OMAP2/3: clockdomain/PRM/CM: move the low-level clockdomain functions ↵Paul Walmsley2012-10-2113-574/+543

For example, OMAP2xxx low-level clockdomain functions go into cm2xxx.c. Then remove the unnecessary clockdomain*xxx*.c files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An interesting effect of using the generic version of linkage.h is that the padding is defined in terms of x86 NOPs, which can have even more interesting effects when the assembly code looks like this: ENTRY(func1) mov x0, xzr ENDPROC(func1) // fall through ENTRY(func2) mov x0, #1 ret ENDPROC(func2) Admittedly, the code is not very nice. But having code from another architecture doesn't look completely sane either. The fix is to add arm64's version of linkage.h, which causes the insertion of proper AArch64 NOPs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If a debugger tries to zero a hardware debug control register, the kernel will try to infer both the type and length of the breakpoint in order to sanity-check against the requested regset type.

| * arm64: No need to set the x0-x2 registers in start_thread()Catalin Marinas2012-10-181-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For historical reasons, ARM used to set r0-r2 in start_thread() to the first values on the user stack when starting a new user application. The same logic has been inherited in AArch64. The x0 register is overridden by the sys_execve() return value so it's always zero on success. The x1 and x2 registers are ignored by AArch64 and EABI AArch32 applications, so we can safely remove the register setting for both native and compat user space. This also fixes a potential fault with the kernel accessing user space stack directly. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Reported-by: Al Viro <viro@zeniv.linux.org.uk>

I have verified that the only code path into s3c2440_clk_add() is from "int __init s3c2440_init(void)", so s3c2440_clk_add can be marked __init_refok instead. Without this patch, building mini2440_defconfig results in: WARNING: vmlinux.o(.text+0x9848): Section mismatch in reference from the function s3c2440_clk_add() to the function .init.text:clkdev_add_table() The function s3c2440_clk_add() references the function __init clkdev_add_table().

But it's not true. These pins are shared by usdhc3 and gpmi-nand. We should have the pins functional for gpmi-nand when usdhc3 is disabled.
