2012-08-01MIPS: Loongson 2: Sort out clock managment.Ralf Baechle3-1/+147
For unexplainable reasons the Loongson 2 clock API was implemented in a module so fixing this involved shifting large amounts of code around. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2011-12-07MIPS: irq: Remove IRQF_DISABLEDYong Zhang1-1/+1
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed.

Loongson builds have an ad-hoc cmdline default of "console=ttyS0,115200 root=/dev/hda1". These settings come from a vendor; I remember builds from Lemote branch requiring a "console=tty" override in order to get a working console. At least on Yeeloong, they're particularly useless: there's no external serial port, and the IDE drive is now recognised as /dev/sda.

2010-04-30MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jumpWu Zhangjin1-1/+19
The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.

2010-02-27MIPS: Loongson: Cleanup the halt and poweroff actionWu Zhangjin1-2/+11
In the old source code, I have let halt and poweroff do the same action, but in reality, they have different meanings. As the manpage of shutdown shows: -r Reboot after shutdown. -H Halt action is to halt or drop into boot monitor on systems that support it. -P Halt action is to turn off the power. and in the real world, some machines(e.g. NAS) did not provide a power button and the shutdown works as reset, so, we need to provide a mechanism to let the users turn off the power safely without breaking the system, such a mechanism is "halt", which only put the system into a dead loop or a power-save mode and print some information to the screen to tell the users to turn off the power safely. $ shutdown -hH now /* loongson_halt, not turn off the power */ $ shutdown -hP now /* loongson_poweroff, work as poweroff */ Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Tested-by: Liu Shiwei <liushiwei@gmail.com> Cc: Liu Shiwei <liushiwei@gmail.com> Cc: linux-mips <linux-mips@linux-mips.org> Patchwork: http://patchwork.linux-mips.org/patch/883/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-12-17MIPS: Loongson 2F: Add CPU frequency scaling supportWu Zhangjin4-3/+37
Loongson 2F supports CPU clock scaling. When put it into wait mode by setting the frequency as ZERO it will stay in this mode until an external interrupt wakes the CPU again. To enable clock scaling support, an external timer of a known stable rate is required.

2009-12-17MIPS: Lemote 2F: Add cs5536 MFGPT timer supportWu Zhangjin4-0/+236
CPUFreq support for Loongson 2F requires an external timer. Because the frequency of the MIPS Timer is related to the CPU frequency which itself is variable another timer of constant frequency is required. Export the mfgpt0 counter disable / enable operations for the coming suspend support to suspend / resume the timer.
