2012-09-10usb/core: use bin2bcd() for bcdDevice in RHSebastian Andrzej Siewior
The kernel's version number is used as decimal in the bcdDevice field of the RH descriptor. For kernel version v3.12 we would see 3.0c in lsusb. I am not sure how important it is to stick with bcd values since this is this way since we started git history and nobody complained (however back then we reported only 2.6).

2008-10-20include/linux/bcd.h: remove commentsAdrian Bunk
- the macros are gone - there's no more code in this file, LGPL + GPL = GPL, and the code that was moved to lib/bcd.c is anyway trivial Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-07-24rtc: BCD codeshrinkDavid Brownell
This updates <linux/bcd.h> to define the key routines as constant functions, which the macros will then call. Newer code can now call bcd2bin() instead of SCREAMING BCD2BIN() TO THE FOUR WINDS. This lets each driver shrink their codespace by using N function calls to a single (global) copy of those routines, instead of N inlined copies of these functions per driver. These routines aren't used in speed-critical code. Almost all callers are in the RTC framework. Typical per-driver savings is near 300 bytes.

2002-12-29[PATCH] BIN_TO_BCD consolidationAndrew Morton
Cleanup patch from Hollis Blanchard <hollis@austin.ibm.com> We have a large number of private implementations of BIN_TO_BCD and BCD_TO_BIN, which are all the same. And a lot of them are inflexible because they modify their arg: #define BIN_TO_BCD(val) ((val)=(((val)/10)<<4) + (val)%10) - Create (in <linux/bcd.h> a generic BIN2BCD/BCD2BIN which does not modify its arg - Create generic BIN_TO_BCD/BCD_TO_BIN which uses the above - Update lots of callers to use the new generic version.
