* watchdog: i.MX: Fix internal/external resetSascha Hauer2017-01-201-2/+14
| | | | | | | | | | | The watchdog can either reset only the SoC or assert the WDOG_B output signal instead. On some boards it's necessary to use the external WDOG_B output to make sure that external devices like the PMIC are also properly resetted. This has been fixed in the Linux driver which honours a fsl,ext-reset-output device tree property to select between both ways. Do the same in the barebox driver.

* watchdog: i.MX: add soc_reset operationSascha Hauer2017-01-201-15/+25
| | | | | | | | On i.MX21 watchdog type the reset operation is really different from the watchdog enable/set timeout operation, so create an extra callback for this instead of folding both things together. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mci: imx-esdhci: remove wrong write protection testSascha Hauer2017-01-191-12/+2
| | | | | | | | | | | Testing for the write protection bit to determine if a card is write protected or not is wrong. The bit may have the wrong value for permanently plugged cards (eMMC) or for boards using a GPIO for write protection detection. Since the core will test for write protection before actually calling into the driver this test can just be removed. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: Allow to partition eMMC boot partitionsSascha Hauer2017-01-192-23/+56
| | | | | | | | | So far the eMMC boot partitions cannot be partitioned from the device tree. Since they are often 4MiB in size they are big enough to hold a barebox image and the environment. Add partition parsing to the boot partitions to allow this usecase. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: partitions: force "partitions" subnodeSascha Hauer2017-01-191-6/+6
| | | | | | | | | The binding states that a subnode containing partition subnodes should have the name "partitions". Enforce this so that we do not parse nodes with other names which may have partition descriptions for other disks. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* i.MX: imx-usb-phy: Add VF610 OF compatiblity stringAndrey Smirnov2017-01-121-0/+2
| | | | | | | | | | From looking at analogous Linux driver code it seems that all of the differences between code "imx23-usbphy" and "vf610-usbphy" pertain to suspend/resume functionality, which shouldn't affetct Barebox.

All i.MX6 devices, with exception of i.MX6SL have a 0x100 byte gap between banks 5 and 6 (or addresses 0x2f and 0x30), so we need to account for that when reading data from shadow memory.
