As the talk is going in SPI framework direction, therefore requesting again.. please do not clutter the *generic* SPI framework to pass on opcodes from flash-driver (like m25p80). (Q)SPI framework should remain generic and independent of any upper layer drivers. Therefore I proposed DT based approach, as an alternative. http://lists.infradead.org/pipermail/linux-mtd/2013-September/048552.html But as Shijie's patches are centric to FSL use-case and qspi-controller, so I cannot pursue my suggestions further. > The driver needs to > write the commands to the device but it's not clear to me if it really > needs to know the specific commands. with regards, pekon ��.n��������+%������w��{.n����z�{��ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
