Re: latest kernel for am35xx
Hey Mark! I don't like to look stupid, but I don't find v3.4 tag here: http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap.git;a=tags please have a look at. There are only a few candidates there for the v3.4 2012/6/1 Mark A.

There are several issues with the am35x code in the current community. However, if you checkout k.o. v3.4, use omap2plus_defconfig, enable CONFIG_TI_DAVINCI_EMAC, and add 'nohlt' to the cmdline, you will be able to boot the am3517evm. Don't try a Suspend-to-RAM though.

tps65910
Hey guys! Who knows how to initialize and use tps65910 driver in linux with am3517? I designed a board using the Craneboard schematic as a reference. Mistral provides the kernel 2.6.32 and it works fine. Now I'm porting the BSP to kernel 3.0.17 and don't know how to implement voltage regulator features with the tps65910 driver (it appeared in kernel 3.0 ) under kernel 3.0 environment. I'm watching board-omap3beagle.c as a reference and tps65910.c driver and can't find any correlation. Any suggestions? Any help is appreciated!

Re: tps65910
Hi Mohammed! Thanks a lot! This code certainly can be used as a reference. I just wonder why it was not possible to rewrite tps65910 driver to comply with current twl interface? For example tps65910 API for the Craneboard is 100% the same as for OMAP3 and therefore porting features from Beagleboard to any board with tps65910 would be like 1-2-3. am33xx BSP is supported by TI, omap3evm is supported by TI, though both BSPs have absolutely different PMIC API in spite of they implement the same features..

tps65930 microphone fails in 3.0.17
Hi colleagues! I'm working with Angstrom Linux where the kernel 3.0.17-115c is currently used. I use a Beagleboard clone with TPS65930 installed instead of TPS65950 on Beagle. Recently I've been using 2.6.32 and a Microphone feature worked fine after applied patches for Devkit8000 to the registers set for TPS65930 in twl4030.c. The problem appeared in the latest kernel 3.0.17 where setting registers to correct values does not enable a Microphone recording. Specifically I don't see the MIC BIAS functioning while I enabled in MICBIAS_CTL (voltage level is zero at allmicrophone pins). The default alsamixer supplied with Angstrom distribution does not let to manage the Microphone bias. Please suggest a direction to follow.. best wishes, Max -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
ks8851 speed regression in kernel 3.0.17-115c
Hi! Current kernel: linux-3.0.17-r115c Download speed: 745kB/sec Previous kernel: 2.6.32-r78 Download speed: 1MB/sec I noticed the regression in speed for ks8851 driver (Micrel KSZ8851-SNL). I used this part with kernel 2.6.32 and the speed was 1MB/s. Then the driver code was changed and for current Linux version linux-3.0.17-r115c the speed is 745kB/s. 25% speed reduce is indeed noticeable. I use Angstrom Linux built in OE environment. Target board is Beagleboard C4. -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
tps65930: MIC does not work
Hi! I use Angstrom Linux with devkit8000 where TPS65930 is installed. Current kernel version is linux-3.0.17-r115c. I can't enable MIC working while it worked in 2.6.28-omap and 2.6.32-r78. I suspect the MIC Bias control does not function because I can't see any voltage level at a microphone jack. Trying to use alsamixer does not let me achieve the goal. I already set registers to necessary values (borrowed from working 2.6.28-omap) but no sound is still captured from a mic by arecord utility. Please suggest how to fix this issue. Thanks in advance.

Problem to set fb timings for a new display
Hi!
I'm using Beagleboard clone with TFT display connected. The display is 3.5
320x240.
I created a new driver for this display for the kernel 2.6.32 (beagleboard
BSP) obtained from the OE environment. When u-boot starts I set the
following variables:
setenv defaultdisplay pt35
setenv dvimode 320x240MR-16@60
All I need is to have timings specified in my driver:
static struct omap_video_timings pt35_timings = {
.x_res = 320,
.y_res = 240,
.pixel_clock= 8000,
.hsw= 30,
.hfp= 40,
.hbp= 0,
.vsw= 5,
.vfp= 13,
.vbp= 4,
};
But with dvimode set to 320x240MR-16@60 an image is rather good, but is
shifted a little. As I understand the timings is calculated by CVT and I
can't change them.
If I set dvimode to 320x240-16@60 then I get timings from
drivers/video/modedb.c:
}, {
/* 320x240 @ 60 Hz, 31.5 kHz hsync, 4:3 aspect ratio */
NULL, 60, 320, 240, 79440, 16, 16, 16, 5, 48, 1,
0, FB_VMODE_DOUBLE
}, {
I want to set margins (porches) for the image but don't know how. Please
advise!
best regards,
Max
