Hi Tudor,
if (nor->spimem) {
struct spi_mem_op op =
SPI_MEM_OP(SPI_MEM_OP_CMD(SPINOR_OP_WRSR, 1),
SPI_MEM_OP_NO_ADDR,
SPI_MEM_OP_NO_DUMMY,
- SPI_MEM_OP_DATA_IN(1, nor->bouncebuf, 1));
This be SPI_MEM_OP_DATA_OUT() in the current mainline code also, right?
I'm testing my under development driver on top of v5.4-rc1, and
flash_lock -u is broken.
Cheers,
John
