Import pending patches to set pinconf settings for SPI-NAND pins on MT7622 identical to what the old proprietary preloader did. Should further increase the reliability of some SNFI-attached SPI-NAND flash chips.

Subject: [PATCH 3/3] mediatek: snfi: adjust drive strength to 12mA like old
|
|
loader does
|
|
|
|
In addition to FM35X1GA, also change the driver strength to 12mA for
|
|
all chips where this is done by the old/legacy U-Boot:
|
|
* Winbond 512Mb
|
|
* Winbond 1Gb
|
|
* Winbond 2Gb
|
|
* GD5F4GQ4UBYIG
|
|
* GD5F4GQ4UAYIG
|
|
* GD5F1GQ4UX
|
|
* GD5F1GQ4UE
|
|
* GD5F2GQ4UX
