2018-12-10drivers: core: Add the option SPL_DM_DEVICE_REMOVE to the KconfigJean-Jacques Hiblot
It is currently not possible to include the support to remove devices in the SPL. This is however needed by platforms that re-select their dtb after DM is initialized; they need to remove all the previously bound devices before triggering a scan of the new DT. Add a Kconfig option to be able to include the support for device removal in the SPL.

2018-12-10power: make most tps drivers and the twl4030 driver compatible with DM_I2CJean-Jacques Hiblot
Those driver are not DM drivers per se (not using the PMIC/regulator framework) and are using the legacy I2C API. Make them compatible with the DM_I2C API.

2018-12-07power: axp209: Limit inrush current for broken boardsOlliver Schinagl
Some boards feature a capacitance on LDO3's output that is too large, causing inrush currents which as a result, shut down the AXP209. This has been reported before, without knowing the actual cause. A fix appeared to be done with commit 0e6e34ac8dbb ("sunxi: Olimex A20 boards: Enable LDO3 and LDO4 regulators"). The description there is a bit misleading, the kernel does not hang during AXP209 initialization, the PMIC shuts down, causing voltages to drop and thus the whole system freezes. While the AXP209 does have the ability to ramp up the voltage slowly, to reduce these inrush currents, the voltage rate control (VRC) however is not applicable when switching on the LDO3 output. Only when going from an enabled lower voltage setting, to a higher voltage setting is the VRC in effect. To work around this problem, we set LDO3 to the lowest possible setting of 0.7 V if it was not yet enabled, and then let the VRC (if enabled) do its thing. It should be noted, that for some undocumented reason, there is a short delay needed between setting the LDO3 voltage register and enabling the power. One would expect that this delay ought to be just after enabling the output power at 0.7 V, but this did not work.

2018-12-07power: axp209: Add support for voltage rate control on LDO3Olliver Schinagl
The AXP209 LDO3 regulator supports voltage rate control, or can set a slew rate. This allows for the power to gradually rise up to the desired voltage, instead of spiking up as fast as possible. Reason to have this can be to reduce the inrush currents for example. There are 3 slopes to choose from, the default, 'none' is a voltage rise of 0.0167 V/uS, a 1.6 mV/uS and a 0.8 mV/uS voltage rise. In ideal world (where vendors follow the recommended design guidelines) this setting should not be enabled by default. Unless of course AXP209 crashes instead of reporting overcurrent condition as it normally should do in this case.

2018-12-06clk: Allow clock defaults to be set during re-reloc state for SPL onlyPhilipp Tomsich
In commit e5e06b65ad65 ("clk: Allow clock defaults to be set also during re-reloc state") the earlier guard against setting clock defaults in pre-reloc state was removed. While it is easy to filter 'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS, no such mechanism exists for the pre-reloc stage of the full U-Boot. With the default defconfig for the RK3399-Q7 (which filter the 'assigned-clocks' property for the DTS used by SPL anyway), this caused a pause during startup of the full U-Boot stage that lasted for almost 10s (due to the CPU not having been clocked up yet). This reintroduces the guard from commit f4fcba5c5baa ("clk: Allow clock defaults to be set also during re-reloc state") and extends it to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will now run in pre-reloc state for SPL, but only after reloc for the full U-Boot.

2018-12-06mtd: sf: Make sf_mtd.c more robustBoris Brezillon
SPI flash based MTD devs can be registered/unregistered at any time through the sf probe command or the spi_flash_free() function. This commit does not try to fix the root cause as it would probably require rewriting most of the code and have an mtd_info object instance per spi_flash object (not to mention that the the spi-flash layer is likely to be replaced by a spi-nor layer ported from Linux). Instead, we try to be as safe as can be by checking the code returned by del_mtd_device() and complain loudly when there's nothing we can do about the deregistration failure. When that happens we also reset sf_mtd_info.priv to NULL, and check for NULL pointer in the mtd hooks so that -ENODEV is returned instead of hitting a NULL pointer dereference exception when the MTD instance is later accessed by a user.

2018-12-06mtd: sf: Unregister the MTD device prior to removing the spi_flash objBoris Brezillon

Implement ->remove() and call spi_flash_mtd_unregister() from there.

2018-12-06mtd: Don't stop MTD partition creation when it fails on one deviceBoris Brezillon
MTD partition creation code is a bit tricky. It tries to figure out when things have changed (either MTD dev list or mtdparts/mtdids vars) and when that happens it first deletes all the partitions that had been previously created and then creates the new ones based on the new mtdparts/mtdids values. But before deleting the old partitions, it ensures that none of the currently registered parts are being used and bails out when that's not the case. So, we end up in a situation where, if at least one MTD dev has one of its partitions used by someone (UBI for instance), the partitions update logic no longer works for other devs. Rework the code to relax the logic and allow updates of MTD parts on devices that are not being used (we still refuse to updates parts on devices who have at least one of their partitions used by someone).
