2020-10-13dt: Remove booting-without-of.rstRob Herring
booting-without-of.rst is an ancient document that first outlined Flattened DeviceTree on PowerPC initially. The DT world has evolved a lot in the 15 years since and booting-without-of.rst is pretty stale. The name of the document itself is confusing if you don't understand the evolution from real 'OpenFirmware'. Most of what booting-without-of.rst contains is now in the DT specification (which evolved out of the ePAPR). The few things that weren't documented in the DT specification are now. All that remains is the boot entry details, so let's move these to arch specific documents. The exception is arm which already has the same details documented.

2019-08-08doc: Add doc for the Ingenic TCU hardwarePaul Cercueil
Add documentation about the Timer/Counter Unit (TCU) present in the Ingenic JZ47xx SoCs. The Timer/Counter Unit (TCU) in Ingenic JZ47xx SoCs is a multi-function hardware block. It features up to to eight channels, that can be used as counters, timers, or PWM. - JZ4725B, JZ4750, JZ4755 only have six TCU channels. The other SoCs all have eight channels. - JZ4725B introduced a separate channel, called Operating System Timer (OST). It is a 32-bit programmable timer. On JZ4770 and above, it is 64-bit. - Each one of the TCU channels has its own clock, which can be reparented to three different clocks (pclk, ext, rtc), gated, and reclocked, through their TCSR register. * The watchdog and OST hardware blocks also feature a TCSR register with the same format in their register space. * The TCU registers used to gate/ungate can also gate/ungate the watchdog and OST clocks. - Each TCU channel works in one of two modes: * mode TCU1: channels cannot work in sleep mode, but are easier to operate. * mode TCU2: channels can work in sleep mode, but the operation is a bit more complicated than with TCU1 channels. - The mode of each TCU channel depends on the SoC used: * On the oldest SoCs (up to JZ4740), all of the eight channels operate in TCU1 mode. * On JZ4725B, channel 5 operates as TCU2, the others operate as TCU1. * On newest SoCs (JZ4750 and above), channels 1-2 operate as TCU2, the others operate as TCU1. - Each channel can generate an interrupt. Some channels share an interrupt line, some don't, and this changes between SoC versions: * on older SoCs (JZ4740 and below), channel 0 and channel 1 have their own interrupt line; channels 2-7 share the last interrupt line. * On JZ4725B, channel 0 has its own interrupt; channels 1-5 share one interrupt line; the OST uses the last interrupt line. * on newer SoCs (JZ4750 and above), channel 5 has its own interrupt; channels 0-4 and (if eight channels) 6-7 all share one interrupt line; the OST uses the last interrupt line.

2018-09-09Drop all 00-INDEX files from Documentation/Henrik Austad
This is a respin with a wider audience (all that get_maintainer returned) and I know this spams a *lot* of people. Not sure what would be the correct way, so my apologies for ruining your inbox. The 00-INDEX files are supposed to give a summary of all files present in a directory, but these files are horribly out of date and their usefulness is brought into question. Often a simple "ls" would reveal the same information as the filenames are generally quite descriptive as a short introduction to what the file covers (it should not surprise anyone what Documentation/sched/sched-design-CFS.txt covers) A few years back it was mentioned that these files were no longer really needed, and they have since then grown further out of date, so perhaps it is time to just throw them out. A short status yields the following _outdated_ 00-INDEX files, first counter is files listed in 00-INDEX but missing in the directory, last is files present but not listed in 00-INDEX. List of outdated 00-INDEX: Documentation: (4/10) Documentation/sysctl: (0/1) Documentation/timers: (1/0) Documentation/blockdev: (3/1) Documentation/w1/slaves: (0/1) Documentation/locking: (0/1) Documentation/devicetree: (0/5) Documentation/power: (1/1) Documentation/powerpc: (0/5) Documentation/arm: (1/0) Documentation/x86: (0/9) Documentation/x86/x86_64: (1/1) Documentation/scsi: (4/4) Documentation/filesystems: (2/9) Documentation/filesystems/nfs: (0/2) Documentation/cgroup-v1: (0/2) Documentation/kbuild: (0/4) Documentation/spi: (1/0) Documentation/virtual/kvm: (1/0) Documentation/scheduler: (0/2) Documentation/fb: (0/1) Documentation/block: (0/1) Documentation/networking: (6/37) Documentation/vm: (1/3) Then there are 364 subdirectories in Documentation/ with several files that are missing 00-INDEX alltogether (and another 120 with a single file and no 00-INDEX). I don't really have an opinion to whether or not we /should/ have 00-INDEX, but the above 00-INDEX should either be removed or be kept up to date. If we should keep the files, I can try to keep them updated, but I rather not if we just want to delete them anyway. As a starting point, remove all index-files and references to 00-INDEX and see where the discussion is going. Signed-off-by: Henrik Austad <> Acked-by: "Paul E.

2006-10-31[MIPS] Fixup migration to GENERIC_TIMEAtsushi Nemoto
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.

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!
