The split into multiple structures of the "ll" register bank is
impractical. It makes it hard to add ll_lfps_timers_2 which is
at offset 0x794, which is outside of the existing "lfps" structure
and would require us to add yet another one.

Instead, move all the "ll" registers into a single usb338x_ll_regs
structure, and add ll_lfps_timers_2 while at it. It will be used
in a subsequent patch.

I tried applying your patches but it resulted in build break. Can you
collect all the dependencies and send a single series? I'm applying on
top of my testing/next branch.

cheers

You mean the 2 net2280 patches ? Or something else ?

What break did you get ? It's just one series of 2 patches.... I'll try
rebasing them against your branch tomorrow.

Cheers,
Ben.

allmodconfig broke with missing fields in whatever structure. I didn't
dig too much, sorry.

After applying [patch 1/2] & [patch 2/2] I could build on  
https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git/ branch  
usb-next. Please note that [PATCH 1/2] was sent twice.

The split into multiple structures of the "ll" register bank is
impractical. It makes it hard to add ll_lfps_timers_2 which is
at offset 0x794, which is outside of the existing "lfps" structure
and would require us to add yet another one.

Instead, move all the "ll" registers into a single usb338x_ll_regs
structure, and add ll_lfps_timers_2 while at it. It will be used
in a subsequent patch.
