-Subject: [PATCH] reset: Add driver for gpio-controlled reset pins
-
-This driver implements a reset controller device that toggle a gpio
-connected to a reset pin of a peripheral IC. The delay between assertion
-and de-assertion of the reset signal can be configured via device tree.

-+GPIO reset controller
-+=====================
-+
-+A GPIO reset controller controls a single GPIO that is connected to the reset
-+pin of a peripheral IC. Please also refer to reset.txt in this directory for
-+common reset controller binding usage.
-+
-+Required properties:
-+- compatible: Should be "gpio-reset"
-+- reset-gpios: A gpio used as reset line. The gpio specifier for this property
-+ depends on the gpio controller that provides the gpio.
-+- #reset-cells: 0, see below
-+
-+Optional properties:
-+- reset-delay-us: delay in microseconds. The gpio reset line will be asserted for
-+ this duration to reset.
-+- initially-in-reset: boolean. If not set, the initial state should be a
-+ deasserted reset line. If this property exists, the
-+ reset line should be kept in reset.
-+
-+example:
-+
-+sii902x_reset: gpio-reset {
-+ compatible = "gpio-reset";
-+ reset-gpios = <&gpio5 0 GPIO_ACTIVE_LOW>;
-+ reset-delay-us = <10000>;
-+ initially-in-reset;
-+ #reset-cells = <0>;
-+};
-+
-+/* Device with nRESET pin connected to GPIO5_0 */
-+sii902x@39 {
-+ /* ... */
-+ resets = <&sii902x_reset>; /* active-low GPIO5_0, 10 ms delay */
-+};

- DMAEngine request API
-
-Formerly these resources were coming HWMOD on OMAP-like SoCs. With the
-impending removal of HWMOD data, drivers are being converted to use the
-"of-dma" method of requesting DMA channels which from DT and can be obtained
-using the dma_request_slave_channel API. Add support to the soc-dmaengine-pcm
-helpers so that we can fetch and open channels using this method.
