Subject: [PATCH] amd/addrlib: add Addr2IsValidDisplaySwizzleMode
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Some "standard" (_S) swizzle modes are displayable on Raven,
even though the micro tile mode says it's not displayable.
Expose the addrlib function to the driver.
