* misc: Add simple driver for some Nuvoton NCT6102D devicesStefan Roese2016-08-16-0/+65
| | | | | | | | | | | This simple driver provides some functions to control some of the integrated devices. The watchdog is enabled per default. This driver adds a function to disable the watchdog. Also the internal legacy UART (io address 0x3f8/0x2f8) is enabled per default. Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Cc: Simon Glass <sjg@chromium.org>
* misc: add Tegra BPMP driverStephen Warren2016-08-15-0/+270
| | | | | | | | | | | | | | | The Tegra BPMP (Boot and Power Management Processor) is a separate auxiliary CPU embedded into Tegra to perform power management work, and controls related features such as clocks, resets, power domains, PMIC I2C bus, etc. This driver provides the core low-level communication path by which feature-specific drivers (such as clock) can make requests to the BPMP. This driver is similar to an MFD driver in the Linux kernel. It is unconditionally selected by CONFIG_TEGRA186 since virtually any Tegra186 build of U-Boot will need the feature.

| | | | | | | | | | | | | | | | | | | | The call op requests that the callee pass a message to the underlying HW or device, wait for a response, and then pass back the response error code and message to the callee.

* | Rename reset to sysresetStephen Warren2016-05-26-123/+124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current reset API implements a method to reset the entire system. In the near future, I'd like to introduce code that implements the device tree reset bindings; i.e. the equivalent of the Linux kernel's reset API. This controls resets to individual HW blocks or external chips with reset signals. It doesn't make sense to merge the two APIs into one since they have different semantic purposes. Resolve the naming conflict by renaming the existing reset API to sysreset instead, so the new reset API can be called just reset.

We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file.

* | allow LED initialization without STATUS_LED_BOOTBernhard Nortmann2015-10-24-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For current U-Boot to initialize status LEDs via status_led_init(), it is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined. This may be a particular concern with GPIO LEDs, where __led_init() is required to correctly set up the GPIO (gpio_request and gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't called, which could leave the user with a non-functional "led" command - due to the fact that the LED routines in gpio_led.c use gpio_set_value() just fine, but the GPIO never got set up properly in the first place. I think having CONFIG_STATUS_LED is sufficient to justify a corresponding call to status_led_init(), even with no STATUS_LED_BOOT defined. To do so, common/board_r.c needs call that routine, so it now is exposed via status_led.h.

* | add generic stubs for GPIO LEDsBernhard Nortmann2015-10-23-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED), it may be useful to have some generic stubs (wrapper functions) for the "colored" LEDs. This allows defining STATUS_LED_* values directly to GPIO numbers, e.g.: #define STATUS_LED_GREEN 248 /* = PH24 */ To keep those optional, it's probably best to introduce an additional configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that. Placing the code in drivers/misc/gpio_led.c also ensures that it automatically depends on CONFIG_GPIO_LED too.

Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading the fuses, we should account for this hole in address space. Similar hole exists between bank 14 and bank 15 of size 0x80 on iMX6QP, iMX6DQ, iMX6SDL and iMX6SX. Note: iMX6SL has only 0-7 banks and there is no hole. Note: iMX6UL doesn't have this one. When reading, we use register offset, so need to account for holes to get the correct address. When writing, we use bank/word index, there is no need to account for holes, always use bank/word index from fuse map.
