Cover letter [PATCH v3 0/2] ARM: MXC: mxc_nand: support i.MX21
Quoted 13 lines · Ivo Clarysse

Allow mxc_nand.c to function on i.MX21 SoCs, since:

1) On i.MX21, if the NFC_INT_MASK bit in NFC_CONFIG1 is set, the NFC_INT bit of NFC_CONFIG2 always reads out zero, even if an operation is completed.

2) On i.MX21, sending a RESET command to the NAND flash controller does not trigger an interrupt, nor does it cause the NFC_INT bit of NFC_CONFIG2 to get set.

3) After reset is performed, NFC registers are again in their default values.

Quoted 6 lines

This patch series:

- (Re-)sets all NFC registers after reset

- Uses enable_irq / disable_irq_nosync instead of NFC_INT_MASK to mask NFC interrupts (allowing NFC_CONFIG2:NFC_INT to used on i.MX21)
