* MIPS: Alchemy: clock framework integration of onchip clocksManuel Lauss2014-07-302-2/+1098
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces common clock framework integration for all configurable on-chip clocks on Alchemy chips: - 2 or 3 PLLs which generate integer multiples of the root rate 12MHz, - 6 dividers which take one of the 3 PLLs as input and divide their rate by either multiples of 2 or 1 (Au1300). - another bank of up to 6 muxes which take either one of the 6 above dividers or one of the PLLs directly and divide their rate further by 1, 2, 3 or 4. - a few other sources which are used by onchip peripherals and are informational. This implementation will take the clock tree as it was set up by boot firmware: all in-kernel boards should continue to work without having to set up the clock tree in board code. CLK_IGNORE_DISABLED will be removed once all drivers have been converted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With binutils 2.24 the attempt to switch with microMIPS mode to MIPS III mode through .set mips3 results in *lots* of warnings like {standard input}: Assembler messages: {standard input}:397: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension during a kernel build. Fixed by using .set arch=r4000 instead. This breaks support for building the kernel with binutils 2.13 which was supported for 32 bit kernels only anyway and 2.14 which was a bad vintage for MIPS anyway.

* MIPS: remove obsolete Kconfig macrosPaul Bolle2013-05-081-20/+2
| | | | | | | | | | | | | | | | | | The support for PB1100, PB1500, and PB1550 got merged into the code for DB1000 and DB1550 code in v3.7. When that was done the three related Kconfig symbols were dropped. But not all related Kconfig macros were removed. Do so now. Note that the PB1100 code in the Au1100 LCD driver is removed entirely and not converted to use its current Kconfig macro. That is done because the macros it uses (PB1100_G_CONTROL, PB1100_G_CONTROL_BL, and PB1100_G_CONTROL_VDD) are never defined. Actually only one of these was ever defined (PB1100_G_CONTROL) but that define was removed in v2.6.34. So, as far as I can tell, this code could have never compiled.

* MIPS: Alchemy: Make 32kHz and r4k timer coexist peacefullyManuel Lauss2012-12-271-20/+5
| | | | | | | | | | | | | | | | Now that the r4k timer is registered no matter what, bump the rating of the Alchemy 32kHz timer so that it gets used when it is working, and fall back on the r4k when it isn't. This fixes a timer-related hang on platform with a working 32kHz timer (the better rated c0 timer stops while executing 'wait' leading to (almost) eternal sleep) and an oops on boot on platforms without a working 32kHz timer (due to double registration of the r4k timer).

| | | | | | | | | | | | A previous patch converted the Alchemy platform to use the OHCI and EHCI platform drivers. As a result, all the common logic to handle USB present in drivers/usb/host/alchemy-common.c has no reason to remain here, so we move it to arch/mips/alchemy/common/usb.c which is a more appropriate place.

What I cannot explain is why this behaviour shows up now and not in earlier kernel versions before. Maybe older PCI code was slower?

* MIPS: Alchemy: Increase minimum timeout for 32kHz timer.Manuel Lauss2012-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | Since a clocksource change post 3.2-rc1, tasks on my DB1500 board hang after random amounts of time (from a few minutes to a few hours), regardless of load. Debugging showed that the compare-match register value is a few seconds lower than the current counter value. The minimum value of 8 was initialy determined by a trial-and-error approach. Currently it is sufficient for all Alchemys (without PCI apparently), independent of CPU clock; only the DB1500 and DB1550 boards experience these timer-related tasks hangs now. This patch increases the minimum timeout by 1 (to 9 counter ticks) which seems sufficient since the systems are still working perfectly fine after over 24 hours.
