And -+a specific power sequence belongs to device, so its description -+is under the device node, please refer to: -+Documentation/devicetree/bindings/power/pwrseq/pwrseq-generic.txt -+ -+Custom power sequence library allocates one power sequence instance at -+bootup periods using postcore_initcall, this static allocated instance is -+used to compare with device-tree (DT) node to see if this library can be -+used for the node or not. When the result is matched, the core API will -+try to get resourses (->get, implemented at each library) for power -+sequence, if all resources are got, it will try to allocate another -+instance for next possible request from host driver. -+ -+Then, the host controller driver can carry out power sequence on for this -+DT node, the library will do corresponding operations, like open clocks, -+toggle gpio, etc. The power sequence off routine will close and free the -+resources, and is called when the parent is removed. And the power -+sequence suspend and resume routine can be called at host driver's -+suspend and resume routine if needed. -+ -+The exported interfaces -+.. kernel-doc:: drivers/power/pwrseq/core.c -+ :export: -diff --git a/MAINTAINERS b/MAINTAINERS -index 845fc25812f1..c0925efb554c 100644 ---- a/MAINTAINERS -+++ b/MAINTAINERS -@@ -10898,6 +10898,15 @@ F: drivers/firmware/psci*.c - F: include/linux/psci.h - F: include/uapi/linux/psci.h - -+POWER SEQUENCE LIBRARY -+M: Peter Chen <Peter.Chen@nxp.com> -+T: git git://git.kernel.org/pub/scm/linux/kernel/git/peter.chen/usb.git -+L: linux-pm@vger.kernel.org -+S: Maintained -+F: Documentation/devicetree/bindings/power/pwrseq/ -+F: drivers/power/pwrseq/ -+F: include/linux/power/pwrseq.h -+ - POWER SUPPLY CLASS/SUBSYSTEM and DRIVERS - M: Sebastian Reichel <sre@kernel.org> - L: linux-pm@vger.kernel.org -diff --git a/drivers/power/Kconfig b/drivers/power/Kconfig -index 63454b5cac27..c1bb0465f956 100644 ---- a/drivers/power/Kconfig -+++ b/drivers/power/Kconfig -@@ -1,3 +1,4 @@ - source "drivers/power/avs/Kconfig" - source "drivers/power/reset/Kconfig" - source "drivers/power/supply/Kconfig" -+source "drivers/power/pwrseq/Kconfig" -diff --git a/drivers/power/Makefile b/drivers/power/Makefile -index ff35c712d824..7db80354b691 100644 ---- a/drivers/power/Makefile -+++ b/drivers/power/Makefile -@@ -1,3 +1,4 @@ - obj-$(CONFIG_POWER_AVS) += avs/ - obj-$(CONFIG_POWER_RESET) += reset/ - obj-$(CONFIG_POWER_SUPPLY) += supply/ -+obj-$(CONFIG_POWER_SEQUENCE) += pwrseq/ -diff --git a/drivers/power/pwrseq/Kconfig b/drivers/power/pwrseq/Kconfig -new file mode 100644 -index 000000000000..c6b356926cca ---- /dev/null -+++ b/drivers/power/pwrseq/Kconfig -@@ -0,0 +1,20 @@ -+# -+# Power Sequence library -+# -+ -+menuconfig POWER_SEQUENCE -+ bool "Power sequence control" -+ help -+ It is used for drivers which needs to do power sequence -+ (eg, turn on clock, toggle reset gpio) before the related -+ devices can be found by hardware, eg, USB bus. -+ -+if POWER_SEQUENCE -+ -+config PWRSEQ_GENERIC -+ bool "Generic power sequence control" -+ depends on OF -+ help -+ This is the generic power sequence control library, and is -+ supposed to support common power sequence usage. -+endif -diff --git a/drivers/power/pwrseq/Makefile b/drivers/power/pwrseq/Makefile -new file mode 100644 -index 000000000000..ad82389028c2 ---- /dev/null -+++ b/drivers/power/pwrseq/Makefile -@@ -0,0 +1,2 @@ -+obj-$(CONFIG_POWER_SEQUENCE) += core.o -+obj-$(CONFIG_PWRSEQ_GENERIC) += pwrseq_generic.o -diff --git a/drivers/power/pwrseq/core.c b/drivers/power/pwrseq/core.c -new file mode 100644 -index 000000000000..6b78a6691683 ---- /dev/null -+++ b/drivers/power/pwrseq/core.c -@@ -0,0 +1,293 @@ -+/* -+ * core.c power sequence core file -+ * -+ * Copyright (C) 2016 Freescale Semiconductor, Inc. -+ * Author: Peter Chen <peter.chen@nxp.com> -+ * -+ * This program is free software: you can redistribute it and/or modify -+ * it under the terms of the GNU General Public License version 2 of -+ * the License as published by the Free Software Foundation. -+ * -+ * This program is distributed in the hope that it will be useful, -+ * but WITHOUT ANY WARRANTY; without even the implied warranty of -+ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
