Any thoughts on that patchset? I kind of hoped that it would make it

Can you check the amount of channels returned? The returned list is
explicitly terminated with a null entry, you can rely on that. Something

Enable NAND access by adding pinmux and NAND flash controller node
to device tree. The NAND chips currently used on the Colibri VF61
requires 8-bit ECC per 512 byte page, hence specify 32-bit ECC
strength per 2k page size.

however raw reads are not possible since the hardware ECC mode need
to be enabled at command time.

- Support ECC with 60-bytes to correct up to 32 bit errors
- Changed to in-band BBT (NAND_BBT_NO_OOB) which also allows ECC modes
which uses up to 60 bytes on 64 byte OOB
- Removed custom (downstream) BBT pattern since BBT table won't be
compatible anyway (due to the change above)

Hi Dmitry,
As the original author of the driver I have some remarks to your review

Define Vybrid's UART0, connected to the Colibri pinout UART_A, as
standard output.

This is a cover letter which provid
which distorts the next measurements. We noticed this when
using the touch screen while measuring the SoC temperature.
The required sampling time is partly given by the SoC, but depends on
the connected analog source too. A device tree property is the right
approach here.

Hi Sanchayan,
I wrote the driver some while ago, so reading it today again feels like
reading someone else's code again :-)
