MIPS: Detect DSP v3 support
DSPv3 is supported on all MIPSr6 systems which indicate support for DSPv2. This doesn't require any changes to the kernel's handling of DSP resources. The patch is to detect support and indicate it in /proc/cpuinfo DSP v3 introduces a new instruction BPOSGE32C Signed-off-by: Zubair Lutfullah Kakakhel <Zubair.Kakakhel@imgtec.com> Reviewed-by: Paul Burton <paul.burton@imgtec.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/12918/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
