da850.dtsi Naming convention Question

I am confused by the naming convention of the da850.dtsi file, and I
am hoping someone can clarify how this works.
Specifically, is defined int he device tree as "gpio: gpio at 226000"
Other TI boards (like omap3.dtsi) use a convention with the address
after the @ symbol.
(in omap3.dtsi, the gpio bank1 is configured as gpio1: gpio at 48310000
where 48310000 is the address of the register)
An attempt was made to correct this in:
c2a3b4bca53a ("ARM: dts: davinci: use proper address after @") where
an fix was made to make gpio: gpio at 1e26000 which would match the
address in the TRM. Unfortunately, it looks as if it was undone
almost right away.
My question is this: Where did the 226000 number originate, and why
would we not want to use the actual address of the 1e26000 as defined
in the Techincal Reference manual?
