2018-08-23reset: Add driver for gpio-controlled reset pinsPhilipp Zabel
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.

2018-08-23MLK-9708 arm: imx: add low power idle support for i.mx6sxAnson Huang
Enable low power idle for i.MX6SX: WFI -> first level idle; WAIT mode -> second level idle; Low power idle -> third level idle, only when system is in low bus mode. In low powe idle mode, below operations will be done: ARM power off; AHB freq lower to 3MHz; PERCLK freq lower to 6MHz; MMDC freq lower to 1MHz; Anatop will be put into low power mode, and regular band-gap will be off and low power band-gap will be enabled instead. Also, in low power idle mode, 24MHz XTAL power will be off and 24MHz clk source will be switched to RC-OSC to save power, this feature is only enabled on i.MX6SX TO1.2. This patch is cherry-picked from L3.14.y, it is the latest version, below conflicts are fixed.

For some bus mux, need to remove CLK_SET_PARENT_GATE flag as they can NOT be disabled, and they are only used by bus-freq and the asm code already follow the correct sequence of changing parent, so we can remove CLK_SET_PARENT_GATE flag to avoid set parent fail after bus-freq transition done.

Merged from 49108fcf7b79ed77d34be33b53a3964b2ac27204 1. Watermark level in sdma use byte as its unit. but asrc driver use word, there is mismatch between them. Here fix this issue and sdma can work more efficiency. 2. Enlarge the larst_period_size, when use small size, for some case, the dma task will timeout, because sdma has no much data for output.
