2018-12-18PCI: imx: Add imx6sx suspend/resume supportLeonard Crestez1-0/+1
Enable PCI suspend/resume support on imx6sx SOCs. This is similar to imx7d with a few differences: * The PM_Turn_Off bit is exposed through an IOMUX GPR, like all other pcie control bits on 6sx. * The pcie_inbound_axi clk needs to be turned off in suspend. On resume it is restored via resume -> deassert_core_reset -> enable_ref_clk. Most of the resume logic is shared with the initial reset after probe.

2018-12-17mmc: host: tmio: Use GPIO descriptorsLinus Walleij1-7/+2
The TMIO MMC driver was passing global GPIO numbers around for card detect. It turns out only one single board in the kernel was actually making use of this feature so it is pretty easy to convert the driver to use only GPIO descriptors. The lines are flagged as GPIO_ACTIVE_[LOW|HIGH] as that is what they are, and since we can now rely on the descriptors to have the right polarity, we set the "override_active_level" to false in mmc_gpiod_request_cd() and mmc_gpiod_request_ro().

2018-11-15regulator: wm8994: Pass descriptor instead of GPIO numberLinus Walleij1-3/+0
Instead of passing a global GPIO number for the enable GPIO, pass a descriptor looked up from the device tree node or the board file decriptor table for the regulator. There is a single board file passing the GPIOs for LDO1 and LDO2 through platform data, so augment this to pass descriptors associated with the i2c device as well. The special GPIO enable DT property for the enable GPIO is nonstandard but this was accomodated in commit 6a537d48461deacc57c07ed86d9915e5aa4b3539 "gpio: of: Support regulator nonstandard GPIO properties".

2018-11-13platform/chrome: straighten out cros_ec_get_{next,host}_event() error codesBrian Norris1-2/+4
cros_ec_get_next_event() is documented to return 0 for success and negative for errors. It currently returns negative for some errors, and non-negative (number of bytes received) for success (including some "no data available" responses as zero). This mostly works out OK, because the callers were more or less ignoring the documentation, and only treating positive values as success (and indepdently checking the modification of 'wakeup'). Let's button this up by avoiding pretending to handle event/wakeup distinctions when no event info was retrieved (i.e., returned 0 bytes). And fix the documentation of cros_ec_get_host_event() and cros_ec_get_next_event() to accurately describe their behavior.

2018-10-15mmc: tmio: remove TMIO_MMC_HAVE_HIGH_REG flagMasahiro Yamada1-7/+0
TMIO_MMC_HAVE_HIGH_REG is confusing due to its counter-intuitive name. All the TMIO MMC variants (TMIO MMC, Renesas SDHI, UniPhier SD) actually have high registers. It is just that each of them implements its own registers there. The original IP from Panasonic only defines registers 0x00-0xff in the bus_shift=1 review. The register area above them is platform-dependent. In fact, TMIO_MMC_HAVE_HIGH_REG is set only by tmio-mmc.c and used to test the accessibility of CTL_SDIO_REGS. Because it is specific to the TMIO MFD variant, the right thing to do is to move such registers to tmio_mmc.c and delete the TMIO_MMC_HAVE_HIGH_REG flag.

Few regulators in BD71837 and BD71847 can output voltages from different voltage ranges. Register interface is arranged so that used range is selected by toggling bits which are not next to actual voltage selection bits. Then the voltage inside selected range is determined by voltage selection bits (as usual). Support BD71837 and BD71847 selectible range voltages using new pickable ranges helpers.

As the irqchip child driver already has a pointer to the parent struct madera it can use that to store the pointer.

2018-08-31regulator: da9063: fix DT probing with constraintsPhilipp Zabel1-7/+9
Commit 1c892e38ce59 ("regulator: da9063: Handle less LDOs on DA9063L") reordered the da9063_regulator_info[] array, but not the DA9063_ID_* regulator ids and not the da9063_matches[] array, because ids are used as indices in the array initializer. This mismatch between regulator id and da9063_regulator_info[] array index causes the driver probe to fail because constraints from DT are not applied to the correct regulator: da9063 0-0058: Device detected (chip-ID: 0x61, var-ID: 0x50) DA9063_BMEM: Bringing 900000uV into 3300000-3300000uV DA9063_LDO9: Bringing 3300000uV into 2500000-2500000uV DA9063_LDO1: Bringing 900000uV into 3300000-3300000uV DA9063_LDO1: failed to apply 3300000-3300000uV constraint(-22) This patch reorders the DA9063_ID_* as apparently intended, and with them the entries in the da90630_matches[] array.

2018-08-29regulator: bd71837: Disable voltage monitoring for LDO3/4Matti Vaittinen1-3/+30
There is a HW quirk in BD71837. The shutdown sequence timings for bucks/LDOs which are enabled via register interface are changed. At PMIC poweroff the voltage for BUCK6/7 is cut immediately at the beginning of shut-down sequence. This causes LDO5/6 voltage monitoring to detect under voltage and force PMIC to emergency state instead of poweroff. Disable voltage monitoring for LDO5 and LDO6 at probe to avoid this.
