2019-05-14mfd: axp20x: Add USB power supply mfd cell to AXP803Chen-Yu Tsai1-0/+5
The AXP803 has a VBUS power input. Its functionality is the same as the one found in the AXP813. Now that the axp20x_usb_power driver supports this variant, we can add an mfd cell for it to use it. Signed-off-by: Chen-Yu Tsai <[email protected]> Signed-off-by: Lee Jones <[email protected]>

2019-05-14platform/chrome: Add support for v1 of host sleep eventEvan Green3-5/+42
Add support in code for the new forms of the host sleep event. Detects the presence of this version of the command at runtime, and use whichever form the EC supports. At this time, always request the default timeout, and only report the failing response via a WARN_ONCE(). Future versions could accept the sleep parameter from outside the driver, and return the response information to usermode or elsewhere.

2019-05-14mfd: cros_ec: Add host_sleep_event_v1 commandEvan Green1-0/+57
Introduce the command and response structures for the second revision of the host sleep event. These structures are part of a new EC change that enables detection of failure to enter S0ix. The EC waits a kernel-specified timeout (or a default amount of time) for the S0_SLP pin to change, and wakes the system if that change does not occur in time.

The AXP223 can be used both using the RSB proprietary bus, or a more traditional I2C bus. The RSB is a faster bus and provides more features (like some integrity checks on the messages), so it's usually preferrable to use it, but since it's proprietary, when we want to use the PMIC in a multi-master setup, the i2c might make sense as well.

2019-05-14mfd: twl6040: Fix device init errors for ACCCTL registerTony Lindgren1-1/+12
I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero: twl6040 0-004b: Failed to write 2d = 19: -121 And then any following register access will produce errors. There 2d offset above is register ACCCTL that gets written on twl6040 powerup. With error checking added to the related regcache_sync() call, the -EREMOTEIO error is reproducable on twl6040 powerup at least duovero. To fix the error, we need to wait until twl6040 is accessible after the powerup. Based on tests on omap4 duovero, we need to wait over 8ms after powerup before register write will complete without failures. Let's also make sure we warn about possible errors too. Note that we have twl6040_patch[] reg_sequence with the ACCCTL register configuration and regcache_sync() will write the new value to ACCCTL.
