This patch adds qspi nodes for am43xx SOC devices. Signed-off-by: Sourav Poddar <sourav.poddar@ti.com> --- Note, checpatch gives 1 warning on flash compatible string "mx66l51235l". This flash is supported in m25p80 driver and the driver is used for other flash devices also. Hence, each flash compatible is not described in[1], but a genric example is shown using spansion flash device.
