Hello,
Trying to get my SMSC9221 working on OMAP4 with DT,
I faced a misconfigured gpmc_fck (dummy clock set to 0)
resulting in serveral division-by-zero, misconfigured
timings and driver lost in the La La Land.
To solve this, patch 1 removes gpmc_fck from the dummy
clocks, and patch 2 adds the gpmc_fck DT node and
reference it from the gpmc node.
Tested on DuoVero/Parlor (OMAP4430) with SMSC9221.
I can't test GPMC myself, but other than that, this set looks good to go.
Thank you. Would you like more test coverage by other people? I would
like to see this in -rc if possible, as it is needed to boot my OMAP4
system.
What OMAP4 system is this? Is this a regression for board that already
has support merged into mainline?
No, it is not yet merged into mainline. I was planning to post the DTS
this week, when most issues are cleared. Looking at the current mainline
boards, no one seems to use the GPMC, so I am just the first one to hit
this issue.
OK, well typically the later -rc's are for fixing observed regressions.
Since your platform is not yet merged in then it's probably fine to push
this for 3.15.
Fair enough. 3.15 is fine.
This also gives time to test the fix for other OMAP-ish processors.
I can do the v3, including OMAP5 and DRA7. But for DRA7, I will need
someone with the TRM telling me where is connected gpmc_fclk (Suman?).
For DRA7, GPMC is connected off L3MAIN1_L3_GICLK (compared to
L3MAIN2_L3_GICLK on OMAP5), both of which are actually just L3_ICLK.
This is the l3_iclk_div in both the omap54xx-clocks.dtsi and
dra7xx-clocks.dtsi files.
regards
Suman
