2005-12-12[ARM] 3201/1: PXA27x: Prevent hangup during resume due to inadvertedly ↵Lothar Wassmann
enabling MBREQ (replaces: 3198/1) Patch from Lothar Wassmann The patch makes sure, that the ouptut functions of pins are restored before restoring the Alternat Function settings, preventing pins from being intermediately configured for undefined or unwanted alternate functions. Here is the original comment: I've got a PXA270 system that uses GPIO80 as nCS4. This system did hang on resume. Digging into the problem I found that the processor stalled immediately when restoring the GAFR2_U register which restored the alternate function for GPIO80. Since the GPDR registers were restored after the GAFR registers, the offending GPIO was configured as input at this point. Thus the alternate function that was in effect after restoring the GAFR was in fact the input function "MBREQ" instead of the output function "nCS4". The "PXA27x Processor Family Developer's Manual" (Footnote in Table 6-1 on page 6-3) states that: "The MBREQ alternate function must not be enabled until the PSSR[RDH] bit field is cleared. For more details, see Table 3-15, "PSSR Bit Definitions" on page 3-71." There is another note in the Developer's Manual (chapter 24.4.2 "GPIO operation as Alternate Function" on page 24-4) stating that: "Configuring a GPIO for an alternate function that is not defined for it causes unpredictable results." Since some GPIOs have no input function defined, and to prevent inadvertedly programming the MBREQ function on some pin, the GAFR registers should be restored after the GPDR registers have been restored. Additional provisions have to be made when the MBREQ function is actually required. The corresponding GAFR bits should not be restored with the regular GAFR restore, but must be set only after the PSSR bits have been cleared.

2005-11-13[ARM] 3160/1: SharpSL: Add driver for Akita specific GPIOsRichard Purdie
Patch from Richard Purdie Add a driver for the extra GPIOs found on the Sharp SL-C1000 (Akita). These GPIOs are found on a Maxim MAX7310 I2C i/o expander chip. A generic GPIO driver for the MAX7310 was attempted but this mini driver is a much simpler and much more effective solution avoiding several issues and complexity the generic driver had (as discussed on LKML). The platform device is required so the device parent can be set correctly which ensures the device is one of the last to suspend and first to resume. Whilst the i2c suspend/resume calls can be influenced, nothing guarantees this is easlier/later than the subsystems the gpios are used on which are all independent of i2c (sound, irda, video/backlight etc.).

2005-11-10[ARM] 3098/1: pxa2xx disable ssp irqLiam Girdwood
Patch from Liam Girdwood This patch allows users of the pxa SSP driver to register their own irq handlers instead of using the default SSP handler. It also cleans up the CKEN clock and irq detection as the values are now stored in a table. This patch replaces 2845/1 Changes:- o Added flags parameter to ssp_init() o Added SSP_NO_IRQ flag to disable registering of ssp irq handler (for drivers that want to register their own handler) o Cleaned up clock and irq detection, values are now stored in table. o Added build changes to allow other drivers (e.g audio) to select the ssp driver. o corgi_ssp.c changed to use new interface.

2005-11-10[ARM] 3096/1: Add SharpSL Zaurus power and battery management core driverRichard Purdie
Patch from Richard Purdie This patch adds a power and battery management core driver which with the addition of the right device files, supports the c7x0 and cxx00 series of Sharp Zaurus handhelds. The driver is complex for several reasons. Battery charging is manually monitored and controlled. When suspended, the device needs to periodically partially resume, check the charging status and then re-suspend. It does without bothering the higher linux layers as a full resume and re-suspend is unnecessary. The code is carefully written to avoid interrupts or calling code outside the module under these circumstances. It also vets the various wake up sources and monitors the device's power situation. Hooks to limit the backlight intensity and to notify the battery monitoring code of backlight events are connected/added as the backlight is one of the biggest users of power on the device.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

Patch from Todd Poynor Add symbols for PXA2xx PWRMODE register M field that selects low-power mode, replace unadorned constants. Honor power mode parameter of pxa_cpu_suspend(mode), no longer force to 3 (sleep). Full Deep Sleep low-power mode support for PXA27x is pending generic PM interfaces to select more than 2 suspend-to-RAM-style power modes, but this is expected soon. This can be hardcoded in the meantime by replacing the pxa_cpu_suspend() parameter value. From David Burrage and Todd Poynor. Try #2 removes one of the register copies and moves the code to save the pxa_cpu_suspend parameter to immediately surround the call that requires the parameter value be preserved.
