| * mfd: pcf50633: Reconnect -ENOMEM error pathLee Jones2014-07-09
| | | | | | | | | | | | | | | | | | | | If platform_device_alloc() or platform_device_add_data() fail during pcf50633_probe(), the current code ignores the return error code and continues to attempt to allocate new platform devices for each of the supported regulators. Instead, if any failures occur we should fail out gracefully by cleaning up after ourselves and return the error. Signed-off-by: Lee Jones <lee.jones@linaro.org>

| * mfd: arizona: Don't use devres for DCVDDCharles Keepax2014-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the Arizona core uses a devm_regulator_get against its own device node to obtain DCVDD. The Arizona core is an MFD device and DCVDD is usually supplied by a child node (arizona-ldo1) of the core. As devres destruction for the MFD device will run after all its children have been destroyed, the regulator will be destroyed before devres calls regulator_put. This causes a warning from both the destruction of the child node, as the regulator is still open, and from the put of the regulator as the regulator device has already been destroyed. This patch handles the regulator get and put without devres to avoid this issue. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cros_ec_spi makes the assumption that a 0-length message will put the spi chip select back to normal (non cs_toggle mode). This used to be the case back on kernel-3.8 on the spi-s3c64xx driver but doesn't appear to be true anymore. It seems like it was a pretty questionable assumption to begin with, so let's fix the code to be more robust. We know that a message with a single 0-length segment _will_ put things back in order. Change cros_ec_spi to handle this. This wasn't a problem on the main user of cros_ec_spi upstream (tegra) because it specified 'google,cros-ec-spi-msg-delay'.

The settings assume most of the regulators are under control of Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as Linux cannot do it. For any board specific changes to these, let's patch them in as changes to the generic data in the follow-up patches. This keeps the board specific changes small. Note that this does not consider the twl5030 errata 27 and 28. That can be added later on after it has been tested. For more information about errata 27 and 28.

Earlier we have configured twl4030 using platform data, but we want to do it for device tree based booting also. In some cases configuring twl4030 is needed for things to work. For example, when rebooting an OMAP3530 at 125 MHz, it hangs. With this patch, TWL4030 will be reset when a warm reset occures, and OMAP3530 does not hang on reboot. Let's add device tree support and configure things for warm reset as the default when compatible = "ti,twl4030-power". More complicated configurations can be added to the driver based on other compatible flags. Note we now also make the pdata const like it should be. This allows use it for match->data with the device tree related functions. Based on earlier patch by Matthias Brugger <matthias.bgg@gmail.com> and Lesly A M <leslyam@ti.com>.

If we have a sleep configuration loaded, and do a warm reset, the device can hang while initializing the wakeup12 sequence. We do have a warning message about wrong order of twl4030 configuration, but in this case it does not help as the sleep configuration was loaded during the previous boot and the state of twl4030 is maintained throughout the warm reset. Fix the issue by clearing any existing sleep configuration before we load the warm reset configuration. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
