module are inactive (clock gating forced at module level) and
enables the module when any gpio in the module is requested.

The module is enabled only when "mod_usage" indicates that no GPIO
in that  module is currently active and the GPIO being requested
is the 1st one to be active in that module.

Each module would be disabled in omap_gpio_free() API when all
GPIOs in a particular module becomes inactive. The module is
re-enabled in omap_gpio_request() API when a GPIO is requested
from the module that was previously disabled.

Since individual GPIO's bookkeeping is added in this patch
via "mod_usage", the same is used in omap_set_gpio_debounce()

Bug fixes to various modules feature additions, notably with ISP,
sDMA etc.

Details about the chip is available here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606

Strategy used:
Strategy to introduce this device into Linux was discussed here:
Ref: http://marc.info/?t=125343303400003&r=1&w=2

Two approaches were available:
a) Consider 3630 generation of devices as a new family of silicon
b) Consider 3630 as an offshoot of 3430 family of devices

As a common consensus, (b) seems to be more valid for 3630 as:
* There are changes which are easily handled by using "FEATURES"
  infrastructure.
  For details how to do this, see thread:
  http://marc.info/?t=125050998500001&r=1&w=2
* Most of existing 34xx infrastructure can be reused(almost 90%+)
- so no ugly if (cpu_is_omap34xx() || cpu_is_omap36xx())
  all over the place
- lesser chance of bugs due to reuse of proven code flow
- 36xx specific handling can still be done where required
  within the existing infrastructure

NOTE:
* If additional 34xx series are added, OMAP3430_REV_ESXXXX can be
  added on top of the existing 3630 ones are renumbered

serial_platform_data needs to be now removed to avoid
oopsing.

Note that mach-omap1 uses struct plat_serial8250_port
array, which requires a null terminator at the end,
and that's why we need to use ARRAY_SIZE - 1. This
is not needed on mach-omap2 as the array used is
struct omap_uart_state, and does not use a null

Reason for the twl4030_codec MFD: the vibra control is actually in the codec
part of the twl4030. If both the vibra and the audio functionality is needed

and APLL at the same time without breaking the other driver.
Also these two has to be able to work without the need for the other driver.

This MFD device will be used by the drivers, which needs resources
from the twl4030 codec like audio and vibra.

The platform specific configuration data is passed along to the

14 years agoFix handling of the HP/Acer 'DMAR at zero' BIOS error for machines with <4GiB RAM.
David Woodhouse [Thu, 19 Nov 2009 02:18:44 +0000 (02:18 +0000)]
Fix handling of the HP/Acer 'DMAR at zero' BIOS error for machines with <4GiB RAM.

Commit 86cf898e1d0fca245173980e3897580db38569a8 ("intel-iommu: Check for
'DMAR at zero' BIOS error earlier.") was supposed to work by pretending
not to detect an IOMMU if it was actually being reported by the BIOS at
physical address zero.

However, the intel_iommu_init() function is called unconditionally, as
are the corresponding functions for other IOMMU hardware.

So the patch only worked if you have RAM above the 4GiB boundary. It
caused swiotlb to be initialised when no IOMMU was detected during early
boot, and thus the later IOMMU init would refuse to run.

But if you have less RAM than that, swiotlb wouldn't get set up and the
IOMMU _would_ still end up being initialised, even though we never
claimed to detect it.

This patch also sets the dmar_disabled flag when the error is detected
during the initial detection phase -- so that the later call to
intel_iommu_init() will return without doing anything, regardless of
whether swiotlb is used or not.

[CPUFREQ] Fix stale cpufreq_cpu_governor pointer

Dave,

Attached is an update of my patch against the cpufreq fixes branch.

Before applying the patch I compiled and booted the tree to see if the panic
was still there -- to my surprise it was not.  This is because of the conversion
of cpufreq_cpu_governor to a char[].

While the panic is kaput, the problem of stale data continues and my patch is
still valid.  It is possible to end up with the wrong governor after hotplug
events because CPUFREQ_DEFAULT_GOVERNOR is statically linked to a default,
while the cpu siblings may have had a different governor assigned by a user.

ie) the patch is still needed in order to keep the governors assigned
properly when hotplugging devices
