Cover letter [PATCH v2 0/3] mxs: add driver for On Chip OTP
From: "Christoph G. Baumann" <[email protected]>
This patch brings read/write support for the On Chip OTP cells in the i.MX23 and i.MX28 processor. The driver uses files (one for each cell) in /sys/fsl_otp as interface. The original code from Freescale was stripped down to the required minimum and ported to 3.x kernels.
