> This patchset will clean, fix, optimize and add multiple devices,

> Platform data for the pasic3-leds driver has been removed, as this

> in the future with an incompatible platform data structure.
> Default setting of the Samsung LCD pixel clock period has been
> increased, so resulting frequency is 50Hz (original 117Hz). Period
> can be possibly incresed even more. At this moment there is no video
> player with IWMMXT support and software only versions cannot make it
> to 30fps. Frequency decreasing has a good impact to memory troughtput
> as LCD controller does not do as many memory bursts as at original
> speed. This was verified with the lat_mem_rd from the lmbench3.
> The Omnivision OV9640 camera has a problem with running on 400kHz
> of the I2C clock. It seems it freezes the bus until PXA I2C driver
> reload. Datasheet says it OK on 400kHz though. There may be some
> compatibility bug in the PXA I2C driver as Omnivision cameras often
> uses special I2C protocol (SCCB).
> Using the CPU frequency scaling (with help of an MAX1587A regulator)
> sometimes causes an SoC failure. It is probably related to the PXA27x
> erratum E37, E36, E80 or E89. Infreqent changes mostly works.
> STUART removal is a prepare for:

> Function was tested on the board_id 0x3a version (specifically on
> the T-Mobile MDA compact).

I am sorry, if you got some of the mails twice. It seems there was a combination of bad timing and filling of my email box (some emails was sent OK, some seemed to be sent OK, but not and some was not sent at all). And I had list of mails from the patchset version 2, MFD/LEDs subsystem relevant patch is only:

	ARM: pxa: magician: Remove pdata for pasic3-leds

On the other hand if you got only a part of the patchset and you want to see missing parts, mail me and I will send you.

Best regards,
Petr Cvek
