Subject: [PATCH 41/46] ARM: pxa: move it8152 PCI support into machine
Date: Fri, 18 Oct 2019 17:41:56 +0200 [thread overview]
Message-ID: <20191018154201.1276638-41-arnd@arndb.de> (raw)
In-Reply-To: <20191018154052.1276506-1-arnd@arndb.de>
The driver was written as a "common" driver that could
be shared between platforms, but it was never actually shared
and now written in a completely portable way either, so just
move it into the platform to avoid header file dependencies.
Unfortunately, this driver uses the DMABOUNCE feature, which
is likely to cause problems in a multiplatform configuration,
need to investigate further. Apparently the cm-x255 only
has 64MB of RAM and does not need bouncing, but the cm-x270
can have anywhere between 32MB and 128MB, which is where
we exceed the 64 MB of address space in the chip.
Another problem is the ARCH_HAS_DMA_SET_COHERENT_MASK flag,
which messes up other PCI implementations.
