Subsystems (2)
PATCH 1/1 MTD: NAND: Select timings for Kioxia TH58NVG3S0HBAI4
From: Rickard x Andersson <[email protected]>
Add timings for Kioxia/Toshiba TH58NVG3S0HBAI4. Timings for this memory matches the timings selected for TH58NVG2S3HBAI4.
This patch increases eraseblock write speed from 5248 KiB/s to 6864 KiB/s and erase block read speed from 8542 KiB/s to 18360 KiB/s
Tested on i.MX6SX.

Please change the title to something like:
"mtd: rawnand: kioxia: Add support for TH58NVG3S0HBAI4"
And we'll be good.
