V3 changes: 1. New comments updated as Kevin mentioned in the third patch; 2. 3530evm works well, AM33xx seems work well with the following changes: + if (cpu_is_am335x()) + return omap2_prm_read_mod_reg(AM33XX_PRM_DEVICE_MOD, + AM33XX_PRM_RSTST_OFFSET)& 0x7f; But since some definitions not ready for am33xx, so I don't give the patch, if they have been updated, feel free to take these.Did you test it on any of AM33xx platform?
Yes. I ever did in v2 as follows shown: The same case works well on am335xevm but with a new patch in mach-omap2/prcm.c I'll send it later. root@ti-omap3:~# uname -a Linux ti-omap3 3.4.3-00635-g82d1d26-dirty #32 Wed Jul 11 16:02:12 CST 2012 armv7l GNU/Linux root@ti-omap3:~# dmesg|grep WDT [ 1.921173] omap_wdt: OMAP WDTimer Rev 0x01: Initial timeout 0sec status= 0x1 root@ti-omap3:~# ./a.out -i 20; for i in `seq 1 20`; do echo $i ; sleep 1;done Set watchdog interval to 20 Current watchdog interval is 20 Last boot is caused by : Watchdog Use: <w> to kick through writing over device file <i> to kick through IOCTL <x> to exit the program x 1 2 [snip] U-Boot SPL 2011.09 (Feb 09 2012 - 15:38:59) Texas Instruments Revision detection unimplemented U-Boot 2011.09 (Feb 09 2012 - 15:11:31) I2C: ready DRAM: 256 MiB WARNING: Caches not enabled Found a daughter card connected NAND: HW ECC Hamming Code selected 256 MiB MMC: OMAP SD/MMC: 0 Net: cpsw Hit any key to stop autoboot: 0 U-Boot#
If you use linux-omap/master pr linux-next branch as a baseline you should have basic things (except hwmod data) available. I will test it and send a patch for this on your behalf (if you are ok with it).
I'm OK for this, thanks Vaibhav.
Note: Change in convention, cpu_is_am335x() => soc_is_am335x()
Yes, agreed. Regards, Zumeng
Thanks, Vaibhav
