OMAP3 DM3730 1GHz mainline support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



HI,

I would like to know about the status for supporting 1GHz of DM3730
processor (omap3) in the kernel mainline.

I have found the omap3-n950-n9.dtsi is supporting opperating-points up
to 1GHz in DT but, is it working?
I have tried to use DT patch for an omap3-igep0030 board but it does
not boot with kernel 4.7-rc1 or higher where N950-1GHz support is
present
http://elinux.org/N950
DT patch: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?h=v4.7-rc1&id=0f4f1542ea0928f4840d308e411797c0dacac239

I have also find that TI have tried to add support in the past for
'enable' this feature in kernels with DT:
http://linux-omap.vger.kernel.narkive.com/WWXOjLOy/repost-patch-2-2-regulator-twl-use-platform-data-in-the-dt-based-boot-also

In addition, adding opperating-points table to the omap3-igep0030 dts
seems that cpufreq generic driver works (kernel 4.3 and 4.5) but
twl4030 is not
handling required voltages and it is always selecting 1.2V voltage
instead of 1.375 for 1GHz or 1.325 for 800MHz.


As it is said in thead: "[REPOST PATCH 2/2] regulator: twl: use
platform data in the DT based boot also"
"NO. 1GHz cannot not be supported by the chip until we have avs
class1.5 and ABB integrated into a proper cpufreq/dvfs solution.

we have tried multiple times in upstream to present a solution"

Do you now about the current status of this or if there is a patch for
testing it?
I tried to apply the patch (regulator: twl: use...) in a kernel 4.3
but it does not work and the same kernel traces still appear:

[    2.766998] omap2_set_init_voltage: unable to find boot up OPP for
vdd_mpu_iva
[    2.774688] omap2_set_init_voltage: unable to set vdd_mpu_iva
[    2.780761] omap2_set_init_voltage: unable to find boot up OPP for vdd_core
[    2.788177] omap2_set_init_voltage: unable to set vdd_core

Thanks,
Daniel
