Subject: [PATCH v9 26/27] PCI: bt1: Set 64-bit DMA-mask
Date: Fri, 13 Jan 2023 20:14:08 +0300 [thread overview]
Message-ID: <20230113171409.30470-27-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20230113171409.30470-1-Sergey.Semin@baikalelectronics.ru>
The DW PCIe RC IP-core is synthesized with the 64-bits AXI address bus.
Since the device is also equipped with the eDMA engine we need to
explicitly set the device DMA-mask so the DMA-engine clients would be able
to allocate the data buffers from the DMA-able memory space.
Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru>

Changelog v7:
- This is a new patch added on v7 stage of the series. (@Robin)
