rockchip: reset: support a (common) rockchip reset drivers

2018-01-09T10:13:32+00:00

Create driver to support the soft reset (i.e. peripheral)
of all Rockchip SoCs.

Example of usage:
i2c driver:
	ret = reset_get_by_name(dev, "i2c", &reset_ctl);
	if (ret) {
		error("reset_get_by_name() failed: %d\n", ret);
	}

	reset_assert(&reset_ctl);
	udelay(50);
	reset_deassert(&reset_ctl);

i2c dts node:
resets = <&cru SRST_P_I2C1>, <&cru SRST_I2C1>;
reset-names = "p_i2c", "i2c";

treewide: replace with error() with pr_err()

2017-10-04T15:59:44+00:00

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// 
@@@@
-error
+pr_err
 (...)
//

dm: reset: add stm32 reset driver

2017-09-22T11:40:01+00:00

This driver is adapted from linux drivers/reset/reset-stm32.c
It's compatible with STM32 F4/F7/H7 SoCs.

This driver doesn't implement .of_match as it's binded
by MFD RCC driver.

To add support for each SoC family, a SoC's specific
include/dt-binfings/mfd/stm32xx-rcc.h file must be added.

This patch only includes stm32h7-rcc.h dedicated for STM32H7 SoCs.
Other SoCs support will be added in the future.

reset: uniphier: refactor reset data and add NAND/eMMC reset lines

2017-08-20T14:06:20+00:00

  - Merge sys_reset data of LD4, Pro4, sLD8 and Pro5

  - Merge sys_reset data of LD11 and LD20

  - Use primitive UNIPHIER_RESETX() macro because bit assignments for
    system reset will be changed for every SoC in the future

  - Add NAND and eMMC resets
