* net: fec_imx: fix timeout off by *1000 errorAhmad Fatoum2018-12-171-5/+5
| | | | | | | | | | | | | read*_poll_timeout's final timeout parameter is in microseconds, but the supplied arguments in fec_imx.c were in nanoseconds, which might lead to barebox getting seemingly stuck in fec_halt (loops for a thousand seconds instead of one). I've tested this still works on an i.MX6D by copying a file over TFTP and verifying the hash is correct.

* video: mtl017: Make sure errno is not used as a regulator pointerAndrey Smirnov2018-12-171-0/+3
| | | | | | | | | | | | Since regulator_get() can return an errno via regulator pointer, we need to make sure we handle that case without passing bogus pointers around. Add code to convert mtl017->regulator to a dummy regulator if regulator_get() fails. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mci: Rely on NULL being a dummy regulatorAndrey Smirnov2018-12-171-10/+9
| | | | | | | | | Since NULL, is a dummy regulator, we can drop a bit of error checking logic and simplify the code if we assing host->supply to NULL in case we can't find an appropriate regulator during probing.

* serial: amba-pl011: Fix regulator_get() return checkAndrey Smirnov2018-12-171-1/+1
| | | | | | | | | | | | NULL is used to designate a dummy regulator, so it it should be safe to use against regulator_enable(). Any value that would retrun true for IS_ERR(), OTOH, is not. Such value would also pass "if (r)" check without any problems. Fix the code to use !IS_ERR() instead.

* of: Add .of suffix to device names from devicetreeSascha Hauer2018-12-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | Previous implementation used to add a number to the device names for devices registered from the device tree which did not have a 'reg' property, thus a device node named "state" resulted in a device name "state.<x>". Current implementation skips that number and we get a device named "state". This conflicts with our barebox state implementation which tries to register a device named "state" itself. We could rename the state device nodes of all our device trees, but it causes less trouble to rename the devices. This adds a ".of" suffix to the device names for devices registered from the device tree which also has the nice effect that they now can easily be recognized.

This leads to an EINVAL return from mtd_erase_align() whenever a partial erase is attempted. At least on the MRAM I tested, a full flash erase did not return an error, but it did not have any effect on the flash either. As erase seems to be entirely unsupported on this class of devices, and it is not necessary anyways, it's better to return early with EOPNOTSUPP. This fixes envfs_save() on a partitioned MRAM.

If we want to check the WP# low or high through STATUS READ and check bit 7, we must reset the device, other operation (eg.erase/program a locked block) can also clear the bit 7 of status register. As we know the status register can be refreshed, if we do some operation to trigger it, for example if we do erase/program operation to one block that is locked, then READ STATUS, the bit 7 of READ STATUS will be 0 indicate the device in write protect, then if we do erase/program operation to another block that is unlocked, the bit 7 of READ STATUS will be 1 indicate the device is not write protect. Suppose we checked the bit 7 of READ STATUS is 0 then judge the WP# is low (write protect), but in this case the WP# maybe high if we do erase/program operation to a locked block, so we must reset the device if we want to check the WP# low or high through STATUS READ and check bit 7.

It can be enabled by selecting CRYPTO_DEV_FSL_CAAM_RNG_SELF_TEST in Kconfig. The original patch included a command line utility to run the self-test, but we choose a different approach here, and run the software self-test automatically when the respective HAB events indicating a RNG ROM self-test failure are found when running habv4_get_status(). Note that habv4_get_status() must be called by the board code before the CAAM device driver is probed for this mechanism to work. Until now there are at least two such known events. The first event was observed on an i.MX6Solo, silicon revision 1.4; the second event is mentioned in the original patch description given above. When an event occured, habv4_get_status() tests if it is one of those known events, and if so, indicates to the CAAM driver to run the software self-test. In this case, printing the respective HAB warning is suppressed to prevent confusion; the software self-test itself will error out in case of recurring RNG self-test failure.
