Merge tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrlgrafted

Pull pin control updates from Linus Walleij:
 "Core changes:

   - Use the non-blocking mux_state_try_select() in the generic MUX pin
     control back-end

   - Free pin maps on pinctrl_generic_to_map() failure in the core
     helpers

  New hardware pin control:

   - Qualcomm Maili TLMM SoC, PMG1110 PMIC, and Eliza LPASS LPI TLMM SoC
     (this is for the low power audio, LPASS = Low Power Audio SubSystem
     portions)

   - Upboard support on top of the Intel pin controller

   - Apple T6030 and T6031 support (just compatible strings)

   - Samsung Exynos 8855 SoC

   - Mediatek MT6858 SoC

   - Rockchip RK3308B and RV1106 SoCs

   - Airoha EN7523 and AN7563 SoCs

  Improvements:

   - Qualcomm TLMM GPIOs are unconditionally marked as wakeup capable

   - Qualcomm improvements on top of the Qualcomm PDC (power domain
     controller) irqchip improvements from tglx:s tree

   - Qualcomm IPQ806x and IPQ9650 non-urgent pin grop fixups

   - The NPCM8xx driver has been put into shape fixing many pin and
     group definitions

   - Some non-urgent Tegra 264 pin assignments are fixed up

   - Some non-urgent fixups to Airoha AN7581 and AN7583 registers and
     pin assignments, missing features etc"

+Description:
+		This file is used to control and show counts of
+		execution time ranges for various types per DMAR.
+
+		Firstly, write a value to
+		/sys/kernel/debug/iommu/intel/dmar_perf_latency
+		to enable sampling.
+
+		The possible values are as follows:
+
+		* 0 - disable sampling all latency data
+
+		* 1 - enable sampling IOTLB invalidation latency data
+
+		* 2 - enable sampling devTLB invalidation latency data
+
+		* 3 - enable sampling intr entry cache invalidation latency data
+
+		Next, read /sys/kernel/debug/iommu/intel/dmar_perf_latency gives
+		a snapshot of sampling result of all enabled monitors.
+
+		Examples in Kabylake:
+
+		::
+
+		 1) Disable sampling all latency data:
+
+		 $ sudo echo 0 > /sys/kernel/debug/iommu/intel/dmar_perf_latency
+
+		 2) Enable sampling IOTLB invalidation latency data
+
+		 $ sudo echo 1 > /sys/kernel/debug/iommu/intel/dmar_perf_latency
+
