* MIPS: Kconfig: remove "config MIPS_DISABLE_OBSOLETE_IDE"Paul Bolle2013-05-081-3/+0
| | | | | | | | | | | | | | | | | | The Kconfig symbol MIPS_DISABLE_OBSOLETE_IDE was added in v2.6.10. It has never been used. Let's remove it. The symbol was originally introduced by the following commit commit 2bfa662b64a7ee593f3039c1d3fd81a7766a63cd Author: Pete Popov <ppopov@embeddedalley.com> Date: Tue Oct 12 06:24:19 2004 +0000 - Db1550 bug fixes - updated defconfig - updated Kconfig to use DMA_COHERENT since new silicon is coherent Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Patchwork: http://patchwork.linux-mips.org/patch/5064/ Acked-by: John Crispin <blogic@openwrt.org>
* 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).

* USB: move common alchemy USB routines to arch/mips/alchemy/common.cFlorian Fainelli2012-10-222-1/+615
| | | | | | | | | | | | 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. This change was suggested by Manuel Lauss.

* MIPS: Alchemy: use the OHCI platform driverFlorian Fainelli2012-10-221-2/+33
| | | | | | | | | | | | | | | | | Convert the Alchemy platform to register the ohci-platform driver, now that the ohci-platform driver properly handles the specific ohci-au1xxx resume from suspend case. This also greatly simplifies the power_{on,off} callbacks and make them work on platform device id instead of checking the OHCI controller base address like what was done in ohci-au1xxx.c. Impacted defconfigs are also updated accordingly to select the OHCI platform driver.

| | | | | | | | | | | | | | The PB1550 is more or less a DB1550 without the PCI IDE controller, a more complicated (read: configurable) Flash setup and some other minor changes.

* MIPS: MTX-1: Add udelay to mtx1_pci_idselBruno Randolf2012-08-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this udelay(1) PCI idsel does not work correctly on the "singleboard" (T-Mobile Surfbox) for the MiniPCI device. The result is that PCI configuration fails and the MiniPCI card is not detected correctly. Instead of PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [mem 0x40000000-0x4fffffff] pci_bus 0000:00: root bus resource [io 0x1000-0xffff] pci 0000:00:03.0: BAR 0: assigned [mem 0x40000000-0x4000ffff] pci 0000:00:00.0: BAR 0: assigned [mem 0x40010000-0x40010fff] pci 0000:00:00.1: BAR 0: assigned [mem 0x40011000-0x40011fff] We see only the CardBus device: PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [mem 0x40000000-0x4fffffff] pci_bus 0000:00: root bus resource [io 0x1000-0xffff] pci 0000:00:00.0: BAR 0: assigned [mem 0x40000000-0x40000fff] pci 0000:00:00.1: BAR 0: assigned [mem 0x40001000-0x40001fff] Later the device driver shows this error: ath5k 0000:00:03.0: cannot remap PCI memory region ath5k: probe of 0000:00:03.0 failed with error -5 I assume that the logic chip which usually supresses the signal to the CardBus card has some settling time and without the delay it would still let the Cardbus interfere with the response from the MiniPCI card. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PB1200 has the CPLD located at an address which on the DB1200 is RAM; reading the Board-ID sometimes results in a PB1200 being detected instead (especially during reboots after long uptimes). On the other hand, the address of the DB1200's CPLD is hosting Flash chips on the PB1200. Test for the DB1200 first and additionally do a quick write-test to the hexleds register to make sure we're writing to the CPLD.

| | | | | | | | | | | | | | | | | | | | | | | | Initially I had to write to both the MASK and ENABLE registers, otherwise the CPLD would generate tons of spurious interrupts. With the change to the demux handler to disable the muxed line, it is now sufficient to disable the interrupt by writing either the enable or mask register.

| | | | | | | | | | | | | | | | | | | | | | | | No test hardware and no (apparent) users. These boards seem very similar to the DB1500, so if required support can be brought back again (I have datasheets) but then with dedicated board code, not tacked on to DB1000 support.

|/ | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols, it's time to get rid of them: Move some of the platform devices to the boards which can use them, Rename a few (unused) constants in the header, Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally delete them altogether from the Alchemy Kconfig file.
