[PATCH 0/3] nvmem: patches (set 2) for 5.18

[Srinivas Kandagatla]

Hi Greg,

Here is final set of nvmem patches for 5.18 which includes

- Add new Sunplus nvmem provider and bindings.
- fix in qfprom to increase blow timeout.

Can you please queue them up for 5.18.

thanks for you help,
srini

[PATCH 1/3] nvmem: qfprom: Increase fuse blow timeout to prevent write fail

[Srinivas Kandagatla]

From: Knox Chiou <knoxchiou@chromium.org>

sc7180 blow fuses got slightly chances to hit qfprom_reg_write timeout.
Current timeout is simply too low. Since blowing fuses is a
very rare operation, so the risk associated with overestimating this
number is low.
Increase fuse blow timeout from 1ms to 10ms.

Sorry for inconvenience, but can you please ignore this set if you have 
not already applied them.

There seems to be a issue with yaml file which fails dt-bindings check 
and there are few more patches that can go for 5.18.

I will a send new set soon.

Thanks for your help

Opps, It looks like these were just applied.

I can send other patches along with fix to yaml as next set, if that 
works for you?
