Subject: [PATCH 5/9] dm: core: Add a new API devfdt_get_addr_index_ptr()
Date: Sun, 12 Sep 2021 11:15:12 +0800 [thread overview]
Message-ID: <20210912031516.24885-5-bmeng.cn@gmail.com> (raw)
In-Reply-To: <20210912031516.24885-1-bmeng.cn@gmail.com>
At present there is only devfdt_get_addr_ptr() which only returns
the first <addr, size> pair in the 'reg' property. Add a new API
devfdt_get_addr_index_ptr() to return the indexed pointer.
