ARM: davinci: dm365 evm: align nand partition table to u-boot

2011-12-05T11:17:19+00:00

Current partition information maintained in kernel does not match with
u-boot, this leads to corruption of u-boot env when we update uImage
from kernel. Patch fixes it to match with u-boot partition information.

ARM: davinci: da850 evm: change audio edma event queue to EVENTQ_0

2011-12-05T11:17:18+00:00

On OMAP-L138 platform, EDMA event queue 0 should be used for audio
transfers so that they are not starved by video data moving on event queue 1.

Commit 48519f0ae03bc7e86b3dc93e56f1334d53803770 (ASoC: davinci: let platform
data define edma queue numbers) had a side-effect of changing this behavior
by making the driver actually honor the platform data passed.

Fix this now by passing event queue 0 as the queue to be used for audio
transfers.

ARM: davinci: dm646x evm: wrong register used in setup_vpif_input_channel_mode

2011-12-05T11:17:17+00:00

The function setup_vpif_input_channel_mode() used the VSCLKDIS register
instead of VIDCLKCTL. This meant that when in HD mode videoport channel 0
used a different clock from channel 1.

Clearly a copy-and-paste error.

ARM: davinci: dm646x does not have a DSP domain

2011-12-05T11:17:16+00:00

Fix the incorrect classification of DSP clock into a
seperate DSP domain on DM646x.

Per the reference guide (http://www.ti.com/lit/ug/spruep9e/spruep9e.pdf)
there is only one "AlwaysON" power domain on DM6467.

ARM: davinci: psc: fix incorrect offsets

2011-12-05T11:17:15+00:00

Seperate PDSTAT and PDCTL registers are defined for
domain 0 and domain 1 where as the code always reads
the domain 0 PDSTAT register and domain 1 PDCTL register.

Fix this issue. While at it, introduce usage of macros
for register masks to improve readability.

ARM: davinci: psc: fix incorrect mask

2011-12-05T11:17:14+00:00

There are 5 LSB bits defined in PDSTAT and the code
currently uses a mask of 1 bit to check the status.

Use a proper mask per the hardware specification.
While at it, use a #define for the mask to improve
readability.

cpuidle: Single/Global registration of idle states

2011-11-07T02:13:58+00:00

This patch makes the cpuidle_states structure global (single copy)
instead of per-cpu. The statistics needed on per-cpu basis
by the governor are kept per-cpu. This simplifies the cpuidle
subsystem as state registration is done by single cpu only.
Having single copy of cpuidle_states saves memory. Rare case
of asymmetric C-states can be handled within the cpuidle driver
and architectures such as POWER do not have asymmetric C-states.

Having single/global registration of all the idle states,
dynamic C-state transitions on x86 are handled by
the boot cpu. Here, the boot cpu  would disable all the devices,
re-populate the states and later enable all the devices,
irrespective of the cpu that would receive the notification first.
