* [MIPS] Alchemy common code style cleanupSergei Shtylyov2008-05-121-43/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix many errors and warnings given by checkpatch.pl: - use of C99 // comments; - missing space between the type and asterisk in a variable declaration; - space between the asterisk and function/variable name; - leading spaces instead of tabs; - space after opening and before closing parentheses; - initialization of a 'static' variable to 0; - missing spaces around assignement/comparison operator; - brace not on the same line with condition (or 'else') in the 'if'/'switch' statement; - missing space between 'if'/'for'/'while' and opening parenthesis; - use of assignement in 'if' statement's condition; - printk() without KERN_* facility level; - EXPORT_SYMBOL() not following its function immediately; - unnecessary braces for single-statement block; - adding new 'typedef' (where including <linux/types.h> will do); - use of 'extern' in the .c file (where it can be avoided by including header); - line over 80 characters. In addition to these changes, also do the following: - insert missing space after opening brace and/or before closing brace in the structure initializers; - insert spaces between operator and its operands; - put the function's result type and name/parameters on the same line; - properly indent multi-line expressions; - remove commented out code; - remove useless initializers and code; - remove needless parentheses; - fix broken/excess indentation; - add missing spaces between operator and its operands; - insert missing and remove excess new lines; - group 'else' and 'if' together where possible; - make au1xxx_platform_init() 'static'; - regroup variable declarations in pm_do_freq() for prettier look; - replace numeric literals with the matching macros; - fix printk() format specifiers mismatching the argument types; - make the multi-line comment style consistent with the kernel style elsewhere by adding empty first line and/or adding space on their left side; - make two-line comments that only have one line of text one-line; - fix typos/errors, capitalize acronyms, etc. in the comments; - fix/remove obsolete references in the comments; - reformat some comments; - add comment about the CPU:counter clock ratio to calc_clock(); - update MontaVista copyright; - remove Pete Popov's and Steve Longerbeam's old email addresses...

* [MIPS] Alchemy: don't unmask timer IRQ earlySergei Shtylyov2008-04-281-6/+2
| | | | | | | | | | | | | | | | | | Defer the unmasking of the count/compare interrupt (IRQ5) till the clockevent driver initialization: - only enable the cascaded IRQs 0 thru 4 in arch_init_irq(); kill the ALLINTS macro -- this change is blessed by AMD as I saw it in their own patch; :-) - do not force IRQ5 enabled in plat_time_init() if PM is enabled and there's no 32 KHz crystal.

* [MIPS] Alchemy: work around clock misdetection on early Au1000Sergei Shtylyov2008-04-011-10/+14
| | | | | | | | | | | | | | | Work around the CPU clock miscalculation on Au1000DA/HA/HB due the sys_cpupll register being write-only, i.e. actually do what the comment before cal_r4off() function advertised for years but the code failed at. This is achieved by just giving user a chance to define the clock explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option, defaulting to 396 MHz if the option is not given... The patch is based on the AMD's big unpublished patch, the issue seems to be an undocumented errata (or feature :-)...

* [MIPS] Fixup migration to GENERIC_TIMEAtsushi Nemoto2006-10-311-98/+0
| | | | | | | | | | | | | | | | | | | | | Since we already moved to GENERIC_TIME, we should implement alternatives of old do_gettimeoffset routines to get sub-jiffies resolution from gettimeofday(). This patch includes: * MIPS clocksource support (based on works by Manish Lachwani). * remove unused gettimeoffset routines and related codes. * remove unised 64bit do_div64_32(). * simplify mips_hpt_init. (no argument needed, __init tag) * simplify c0_hpt_timer_init. (no need to write to c0_count) * remove some hpt_init routines. * mips_hpt_mask variable to specify bitmask of hpt value. * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read. * convert ip27_do_gettimeoffset to ip27_hpt_read. * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read. * simplify sb1250 hpt functions.

* [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)Atsushi Nemoto2006-09-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
