kernel/drivers/crypto/qcom-rng.c, branch linux-5.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.1.y2018-07-27T11:04:32Zcrypto: qcom-rng - Add ACPI support2018-07-27T11:04:32ZTimur Tabitimur@codeaurora.org2018-07-16T05:50:27Zurn:sha1:d96542ac1020ecd47d2a1668384694789b65cb91
Add support for probing on ACPI systems, with ACPI HID QCOM8160.
On ACPI systems, clocks are always enabled, the PRNG should
already be enabled, and the register region is read-only.
The driver only verifies that the hardware is already
enabled never tries to disable or configure it.

crypto: qcom-rng - Add support for prng-ee2018-07-27T11:04:32ZVinod Koulvkoul@kernel.org2018-07-16T05:50:26Zurn:sha1:ba3ab6371cdda214bf3d416edae62809a68d0b73
Qcom 8996 and later chips features multiple Execution Environments
(EE) and secure world is typically responsible for configuring the
prng.
Add driver data for qcom,prng as 0 and qcom,prng-ee as 1 and use
that to skip initialization routine.

This ports the Qcom prng from older hw_random driver.
No change of functionality and move from hw_random to crypto
APIs is done.
