| |\ | | | | | | | | | | | | | | | | | | Fixes a merge conflict against the x86 tree caused by a fix to atomic.h which I renamed to atomic_long.h. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
| * | asm-generic: rename page.h and uaccess.hArnd Bergmann2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current asm-generic/page.h only contains the get_order function, and asm-generic/uaccess.h only implements unaligned accesses. This renames the file to getorder.h and uaccess-unaligned.h to make room for new page.h and uaccess.h file that will be usable by all simple (e.g. nommu) architectures.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing asm-generic/atomic.h only defines the atomic_long type. This renames it to atomic-long.h so we have a place to add a truly generic atomic.h that can be used on all non-SMP systems.

| * | asm-generic: introduce asm/bitsperlong.hArnd Bergmann2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing asm-generic versions are incomplete and included by some architectures. New architectures should be able to use a generic version, so rename the existing files and change all users, which lets us add the new files.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the mode pin code to keep the pin definitions in one place. The mode pins values are now the value of the bit instead of bit number. With this patch in place the sh7785 header file contains mode pin comments.

| * flat: fix data sections alignmentOskar Schirmer2009-05-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flat loader uses an architecture's flat_stack_align() to align the stack but assumes word-alignment is enough for the data sections. However, on the Xtensa S6000 we have registers up to 128bit width which can be used from userspace and therefor need userspace stack and data-section alignment of at least this size. This patch drops flat_stack_align() and uses the same alignment that is required for slab caches, ARCH_SLAB_MINALIGN, or wordsize if it's not defined by the architecture. It also fixes m32r which was obviously kaput, aligning an uninitialized stack entry instead of the stack pointer.

With this patch applied the board code can add their own function to export the cpu mode pin configuration. In most cases this will be a constant bitmap, but boards that allow reading this from a register can instead read out the pin state from hardware.

| | | | | | | | | | | | | | | | | | | | | | | | This adopts the OMAP clock framework debugfs bits and replaces the aging procfs bits.

| * | sh: clkfwk: rate table construction and rounding for SH7785.Paul Mundt2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for constructing a rate table by looking at potential divisors for a specified clock. Each FQRMR clock is given its own table. Presently each table is rebuilt when the parent propagates down a new rate, so some more logic needs to be added to do this more intelligently. Additionally, a fairly generic round_rate() implementation is then layered on top of it, which subsequently provides us with cpufreq support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the SH7785 CPU code as well as the SH7785LCR board support code for making use of the newly refactored clock framework. Support for the legacy CPG clocks is dropped at this point, with the extal frequency fed in from the board code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: clkfwk: Rework legacy CPG clock handling.Paul Mundt2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | This moves out the old legacy CPG clocks to their own file, and converts over the existing users. With these clocks going away and each CPU dealing with them on their own, CPUs can gradually move over to the new interface. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only user for this is the SH-Mobile r_clk, which is now added as a root clock and can be kicked via propagate_rate() as usual. Given that, there is no longer any need for the special clk_recalc_rate(), so we kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This causes the generic clk_set_parent() implementation to be a bit more intelligent. A clk_reparent() is added to move the clock over to the new parent's sibling list, which then allows the generic rate propagation code to succeed. This also becomes a nop if the new and old parents are unchanged. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a couple of instances where a clk_enable() can fail, which the SH-Mobile code presently handles, but doesn't get reported all the way back up. This fixes up the return type so the errors make it all the way down to the drivers. Additionally, we now also error out properly if the parent enable fails.

| * | | sh: clkfwk: Consolidate the ALWAYS_ENABLED / NEEDS_INIT mess.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no real distinction here in behaviour, either a clock needs to be enabled on initialiation or not. The ALWAYS_ENABLED flag was always intended to only apply to clocks that were physically always on and could simply not be disabled at all from software. Unfortunately over time this was abused and the meaning became a bit blurry. So, we kill off both of all of those paths now, as well as the newer NEEDS_INIT flag, and consolidate on a CLK_ENABLE_ON_INIT. Clocks that need to be enabled on initialization can set this, and it will purposely enable them and bump the refcount up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
