Subject: [RFC 2/5] of: Move of_dma_get_range to of_address.h
Date: Fri, 23 Jul 2021 14:40:28 -0700	[thread overview]
Message-ID: <20210723214031.3251801-3-atish.patra@wdc.com> (raw)
In-Reply-To: <20210723214031.3251801-1-atish.patra@wdc.com>

Currently, of_dma_get_range is kept in of_private.h as it is used by only
OF support code.

Move it to of_address.h so that it can be used by the code outside OF
support code.
