Subject: [PATCH v2 2/2] ARM: AM43XX: HWMOD: Add rtc hwmod
The patch adds rtc hwmod. RTC module The RTC module is physically
present on the AM438x SoC used on AM43X-EPOS-EVM, but it is permanently
disabled. A secure RTC is used instead on these devices, where needed.
. Hence adding it selectively using a seprate list to get RTC Module
functional on the other am43x SoCs used on am437x-gp-evm and
am437x-sk-evm.
Signed-off-by: Keerthy <j-keerthy@...com>

Changes in v2:
Inverted the checking logic to accommodate registering for all
the SoCs compatible to am4372 and removed the negating am438x logic
to register rtc hwmods as suggested by Paul.
