1 | Freescale i.MX System Reset Controller | ||
2 | ====================================== | ||
3 | |||
4 | Please also refer to reset.txt in this directory for common reset | ||
5 | controller binding usage. | ||
6 | |||
7 | Required properties: | ||
8 | - compatible: Should be "fsl,<chip>-src" | ||
9 | - reg: should be register base and length as documented in the | ||
10 | datasheet | ||
11 | - interrupts: Should contain SRC interrupt and CPU WDOG interrupt, | ||
12 | in this order. | ||
13 | - #reset-cells: 1, see below | ||
14 | |||
15 | example: | ||
16 | |||
17 | src: src@020d8000 { | ||
18 | compatible = "fsl,imx6q-src"; | ||
19 | reg = <0x020d8000 0x4000>; | ||
20 | interrupts = <0 91 0x04 0 96 0x04>; | ||
21 | #reset-cells = <1>; | ||
22 | }; | ||
23 | |||
24 | Specifying reset lines connected to IP modules | ||
25 | ============================================== | ||
26 | |||
27 | The system reset controller can be used to reset the GPU, VPU, | ||
28 | IPU, and OpenVG IP modules on i.MX5 and i.MX6 ICs. Those device | ||
29 | nodes should specify the reset line on the SRC in their resets | ||
30 | property, containing a phandle to the SRC device node and a | ||
31 | RESET_INDEX specifying which module to reset, as described in | ||
32 | reset.txt | ||
33 | |||
34 | example: | ||
35 | |||
36 | ipu1: ipu@02400000 { | ||
37 | resets = <&src 2>; | ||
38 | }; | ||
39 | ipu2: ipu@02800000 { | ||
40 | resets = <&src 4>; | ||
41 | }; | ||
42 | |||
43 | The following RESET_INDEX values are valid for i.MX5: | ||
44 | GPU_RESET 0 | ||
45 | VPU_RESET 1 | ||
46 | IPU1_RESET 2 | ||
47 | OPEN_VG_RESET 3 | ||
48 | The following additional RESET_INDEX value is valid for i.MX6: | ||
49 | IPU2_RESET 4 | ||

2 | * Address map functions for Marvell EBU SoCs (Kirkwood, Armada | ||
3 | * 370/XP, Dove, Orion5x and MV78xx0) | ||
4 | * | ||
5 | * This file is licensed under the terms of the GNU General Public | ||
6 | * License version 2. This program is licensed "as is" without any | ||
7 | * warranty of any kind, whether express or implied. | ||
8 | * | ||
9 | * The Marvell EBU SoCs have a configurable physical address space: | ||
10 | * the physical address at which certain devices (PCIe, NOR, NAND, | ||
11 | * etc.) sit can be configured. The configuration takes place through | ||
12 | * two sets of registers: | ||
13 | * | ||
14 | * - One to configure the access of the CPU to the devices. Depending | ||
15 | * on the families, there are between 8 and 20 configurable windows, | ||
16 | * each can be use to create a physical memory window that maps to a | ||
17 | * specific device. Devices are identified by a tuple (target, | ||
18 | * attribute). | ||
19 | * | ||
20 | * - One to configure the access to the CPU to the SDRAM. There are | ||
21 | * either 2 (for Dove) or 4 (for other families) windows to map the | ||
22 | * SDRAM into the physical address space. | ||
23 | * | ||
24 | * This driver: | ||
25 | * | ||
26 | * - Reads out the SDRAM address decoding windows at initialization | ||
27 | * time, and fills the mvebu_mbus_dram_info structure with these | ||
28 | * informations. The exported function mv_mbus_dram_info() allow | ||
29 | * device drivers to get those informations related to the SDRAM | ||
30 | * address decoding windows. This is because devices also have their | ||
31 | * own windows (configured through registers that are part of each | ||
32 | * device register space), and therefore the drivers for Marvell | ||
33 | * devices have to configure those device -> SDRAM windows to ensure | ||
34 | * that DMA works properly. | ||
35 | * | ||
36 | * - Provides an API for platform code or device drivers to | ||
37 | * dynamically add or remove address decoding windows for the CPU -> | ||
38 | * device accesses. This API is mvebu_mbus_add_window(), | ||
39 | * mvebu_mbus_add_window_remap_flags() and | ||
40 | * mvebu_mbus_del_window(). Since the (target, attribute) values | ||
41 | * differ from one SoC family to another, the API uses a 'const char | ||
42 | * *' string to identify devices, and this driver is responsible for | ||
43 | * knowing the mapping between the name of a device and its | ||
44 | * corresponding (target, attribute) in the current SoC family. | ||
45 | * | ||
46 | * - Provides a debugfs interface in /sys/kernel/debug/mvebu-mbus/ to | ||
47 | * see the list of CPU -> SDRAM windows and their configuration | ||
48 | * (file 'sdram') and the list of CPU -> devices windows and their | ||
49 | * configuration (file 'devices'). | ||
