watchdog: aspeed: restore default value of reset_mask

2018-10-22T13:18:49Z

This is required for the current Linux kernel to reboot. It should also probably be fixed in Linux. Signed-off-by: Cédric Le Goater Reviewed-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

aspeed: Refactor SCU to use consistent mask & shift

2017-05-08T15:57:35Z

Refactor SCU header to use consistent Mask & Shift values. Now, consistently, to read value from SCU register, mask needs to be applied before shift. Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass

aspeed: Add support for Clocks needed by MACs

2017-05-08T15:57:35Z

Add support for clocks needed by MACs to ast2500 clock driver. The clocks are D2-PLL, which is used by both MACs and PCLK_MAC1 and PCLK_MAC2 for MAC1 and MAC2 respectively. The rate of D2-PLL is hardcoded to 250MHz -- the value used in Aspeed SDK. It is not entirely clear from the datasheet how this clock is used by MACs, so not clear if the rate would ever need to be different. So, for now, hardcoding it is probably safer. The rate of PCLK_MAC{1,2} is chosen based on MAC speed selected through hardware strapping. So, the network driver would only need to enable these clocks, no need to configure the rate.

aspeed: Add P-Bus clock in ast2500 clock driver

Add P-Bus Clock support to ast2500 clock driver. This is the clock used by I2C devices. Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass

aspeed: AST2500 Pinctrl Driver

2017-05-08T15:57:33Z

This driver uses Generic Pinctrl framework and is compatible with the Linux driver for ast2500: it uses the same device tree configuration. Not all pins are supported by the driver at the moment, so it actually compatible with ast2400. In general, however, there are differences that in the future would be easier to maintain separately.

aspeed: Refactor AST2500 RAM Driver and Sysreset Driver

2017-05-08T15:57:32Z

This change switches all existing users of ast2500 Watchdog to Driver Model based Watchdog driver. To perform system reset Sysreset Driver uses first Watchdog device found via uclass_first_device call. Since the system is going to be reset anyway it does not make much difference which watchdog is used. Instead of using Watchdog to reset itself, SDRAM driver now uses Reset driver to do that. These were the only users of the old Watchdog API, so that API is removed. This all is done in one change to avoid having to maintain dual API for watchdog in between.

aspeed: Reset Driver

2017-05-08T15:57:32Z

Add Reset Driver for ast2500 SoC. This driver uses Watchdog Timer to perform resets and thus depends on it. The actual Watchdog device used needs to be configured in Device Tree using "aspeed,wdt" property, which must be WDT phandle, for example: rst: reset-controller { compatible = "aspeed,ast2500-reset"; aspeed,wdt = <&wdt1>; } Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass

aspeed: Make SCU lock/unlock functions part of SCU API

2017-05-08T15:57:31Z

Make functions for locking and unlocking SCU part of SCU API. Many drivers need to modify settings in SCU and thus need to unlock it first. This change makes it possible. Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass

aspeed: Watchdog Timer Driver

2017-05-08T15:57:31Z

This driver supports ast2500 and ast2400 SoCs. Only ast2500 supports reset_mask and thus the option of resettting individual peripherals using WDT. Signed-off-by: Maxim Sloyko Reviewed-by: Simon Glass
