Commit 52060836f79 ("dt-bindings: omap-rng: Document SafeXcel IP-76
device variant") update the omap_rng Device Tree binding to add support
for the IP-76 variation of the IP. As part of this change, a "clocks"
property was added, but is indicated as "Required", while it is in fact
"Optional": some
Commit 383212425c926 ("hwrng: omap - Add device variant for SafeXcel
IP-76 found in Armada 8K") added support for the SafeXcel IP-76 variant
of the IP. This modification included getting a reference and enabling a
clock. Unfortunately, this was done *after* writing to the
RNG_INTMASK_REG register.
The omap-rng driver currently uses of_clk_get() to get a reference to
the clock, but never releases that reference. This commit fixes that by
using devm_clk_get() instead.

The INTMASK_REG register does not exist on EIP76. Due to this, the call:
omap_rng_write(priv, RNG_INTMASK_REG, RNG_SHUTDOWN_OFLO_MASK);
ends up, through the reg_map_eip76[] array, in accessing the register at
offset 0, which is the RNG_OUTPUT_0_REG. This by itself doesn't cause
any problem, bu
Hello,
This small patch series brings a few fixes and improvements to the
omap_rng driver. The first fix is particularly important, as it fixes
using the driver built as a module on SoCs that require a clock for
the IP to work properly.
Thanks,
Thomas

hwrng: omap - write
Currently, the code that takes a reference to the clock and enables it
is located inside of_get_omap_rng_device_details(), called only when
probing through the Device Tree.
However, there is nothing that makes this clock logic dependent on the
Device Tree, so it makes more sense to have it in omap
