[Naresh Kamboju]

[If it is already reported please ignore]

LKFT test reported regression on TI BeagleBoard-X15 arm32 bit platform as
The device was not able to detect SATA drive.

dmesg short log:
----------------------
jitterentropy: Initialization failed with host not compliant with
requirements: 2
ata1: SATA max UDMA/133 mmio [mem 0x4a140000-0x4a1410ff] port 0x100 irq 101
wkupaon-clkctrl:0068:0: failed to disable
ata1: SATA link down (SStatus 0 SControl 300)
ata1: softreset failed (1st FIS failed)

Our bisect script pointed this as the first bad commit on linux
mainline master branch.

    ARM: OMAP2+: Drop legacy platform data for dra7 sata

    We can now probe devices with ti-sysc interconnect driver and dts data.
    Let's drop the related platform data and custom ti,hwmods dts property.

    As we're just dropping data, and the early platform data init is based on
    the custom ti,hwmods property, we want to drop both the platform data and
    ti,hwmods property in a single patch.

steps to reproduce:
-------------------------
- Build arm zImage/dtb/modules on mainline tree and configs
- connect SATA drive and boot x15 device
- check the dmesg for failed logs
 - check to find /dev/sda

Steps to build:
--------------------
# TuxMake is a command line tool and Python library that provides
# portable and repeatable Linux kernel builds across a variety of
# architectures, toolchains, kernel configurations, and make targets.
#
# TuxMake supports the concept of runtimes.
# See https://docs.tuxmake.org/runtimes/, for that to work it requires
# that you install podman or docker on your system.
#
# To install tuxmake on your system globally:
# sudo pip3 install -U tuxmake
#
# See https://docs.tuxmake.org/ for complete documentation.
