| |
From: Steffen Trumtrar <s.trumtrar@pengutronix.de>
Add binding documentation for the Freescale RNGC found on some i.MX2/3 SoCs.
Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by: Martin Kaiser <martin@kaiser.cx> --- Changes in v6: - be more precise about rngc and rngb - get rid of mxc, rename the file to imx-rngc.txt - reformat the compatible strings - use RNGC instead of RNG - clarify that clock is not optional (remove "should contain")
Changes in v5: none
Changes in v4: none
Changes in v3: - add compatible string for imx35 - remove imx5 from the commit message, I couldn't find an i.MX SOC that has RNGC
Changes in v2: none
