dt: Remove booting-without-of.rst

2020-10-13T18:33:16Z

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.

Pull MIPS updates from Paul Burton: "Main MIPS changes: - boot_mem_map is removed, providing a nice cleanup made possible by the recent removal of bootmem. - Some fixes to atomics, in general providing compiler barriers for smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or MIPS32 systems using cmpxchg64(). - Conversion to the new generic VDSO infrastructure courtesy of Vincenzo Frascino. - Removal of undefined behavior in set_io_port_base(), fixing the behavior of some MIPS kernel configurations when built with recent clang versions. - Initial MIPS32 huge page support, functional on at least Ingenic SoCs. - pte_special() is now supported for some configurations, allowing among other things generic fast GUP to be used. - Miscellaneous fixes & cleanups. And platform specific changes: - Major improvements to Ingenic SoC support from Paul Cercueil, mostly enabled by the inclusion of the new TCU (timer-counter unit) drivers he's spent a very patient year or so working on.

doc: Add doc for the Ingenic TCU hardware

2019-08-08T22:30:05Z

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.
