[PATCH 1/2] ASoC: tlv320aic3x: Add compatible strings for specific devices

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The driver supports a range of devices but currently doesn't allow those device names to be used for enumeration on DT. Add the currently listed I2C IDs as compatible strings.

[PATCH] arm64: KVM: Support X-Gene guest VCPU on APM X-Gene host

by Anup Patel

This patch allows us to have X-Gene guest VCPU when using KVM arm64 on APM X-Gene host. We add KVM_ARM_TARGET_XGENE_V8 for X-Gene compatible guest VCPU and we return KVM_ARM_TARGET_XGENE_V8 in kvm_target_cpu() when running on X-Gene host.

[PATCH] mfd: sec: Add register cache for interrupt mask registers

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The performance of regmap-irq is improved if the interrupt mask registers can be cached since it does read/modify/update cycles so start using the register cache infrastructure for those registers. We should use this more widely but I don't have a datasheet and this is a nice, conservative starting point.
