Most of the SoC updates in this cycle are cleanups and moves to more
modern infrastructure:
- Davinci was moved to common clock framework
- OMAP1-based Amstrad E3 "Superphone" saw a bunch of cleanups to the
keyboard interface (bitbanged AT keyboard via GPIO).
- Removal of some stale code for Renesas platforms
- Power management improvements for i.MX6LL

The PMIC_DA9063 is a complete misnomer, it denotes the value of the DA9063 chip ID register, so rename it as such. It is also the value of chip ID register of DA9063L though, so drop the enum as all the DA9063 "models" share the same chip ID and thus the distinction will have to be made using DT or otherwise.

Two framebuffer device-node names were looked up during probe, but were
only used as flags to indicate the presence of two framebuffer device.
Drop the unused framebuffer name along with a likewise unused device
pointer from the driver data, and update the platform data to pass in
booleans instead of the framebuffer strings. This allows us do drop the
node references acquired during probe, which would otherwise leak.
Note that there are no other in-kernel users of the modified
platform-data fields.

Quite a lot of core work this time around, though not 100% successful. We gained support for runtime mode changes thanks to David Collins and improved support for write only regulators (ones where we can't read back the configuration) from Douglas Anderson. There's been quite a bit of work from Linus Walleij on converting from specfying GPIOs by numbers to descriptors. Sadly the testing turned out to be less good than we had hoped and so a lot of this had to be reverted. We also have the start of updates to use coupled regulators from Maciej Purski, unfortunately there are further problems there so the last couple of patches have been reverted. We also have new drivers for BD71837 and SY8106A devices, SAW regulators on Qualcomm SPMI and dropped support for some preproduction chips that never made it to market from the AB8500 driver. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAlsarcETHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0B4HB/9MFV/MK7Hw2hsVCX3qWTiH4tJ/X0MG tGz1PfmbH0CJ9ly5g+rvCoT+1/s7BydKzi1cd1RHnimBv2U1XagwSny3LNEcJs2Q pmhpGViakkQI/Y2h+u/j0Jk1nE+jTiKk+1ozUB7YnPekrGyQlf7TMhvKOLTvLKyX 56jdNxcW0MgSnXV2N6y4NpWhgvrQwvKjacTxV5iX7WP2rnK2WNFeG7Q859buhtI0 znRi+tO5hZsw5T44ickdPfotZn+i5o7MYLCkkaA2h1EwtpbYwVINfUjp3KtuyFhH 3B9GmCsjjN2Z2eInnkpzWfVXK2S1Vlp6+ka2FSs+U/4rVdd3Bw2KkblS =Ftua -----END PGP SIGNATURE----- Merge tag 'regulator-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "Quite a lot of core work this time around, though not 100% successful.

This adds the generic core support for Cirrus Logic "Madera" class codecs. These are complex audio codec SoCs with a variety of digital and analogue I/O, onboard audio processing and DSPs, and other features. These codecs are all based off a common set of hardware IP so can be supported by a core of common code (with a few minor device-to-device variations).

This patch adds a header file of register definitions for Cirrus Logic "Madera" class codecs. These codecs are all based off a common set of hardware IP so have a common register map (with a few minor device-to-device variations). The registers.h file is tool-generated directly from the hardware design but has been manually stripped down to reduce size (full register map is >44000 lines). All names are kept the same as datasheet names so that they can be cross-referenced between source and datasheet without confusion. The register map layout is kept fully-defined rather than factored into macros and/or block-indexing code. The major reasons for this are: - #1 is that it makes the source highly greppable, which is important. "What does the driver do with register bits XYZ" or "Where does it use register bits XYZ" are commonly types of questions. These can be quickly answered by a grep. Squashing definitions into generator macros or block- indexing code is a way of defeating grep. - most of the register definitions are used in tables, so a constant value is required. Using generator macros make the table definition clunky and obscure. - the code is clearer when it's there in the source exactly what register and field it is using - it is easier to diff the register map of a new (unsupported) codec against what is already supported and merge in differences - it makes the register map available in source for maintenance/debugging instead of having to refer back to the datasheet for a register map Signed-off-by: Richard Fitzgerald <rf@opensource.cirrus.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Also adds the Chromebook Tablet switch driver, which is useful for x86 convertible Chromebooks. Other misc. cleanup.

Instead of passing a global GPIO number, pass a descriptor looked up with the standard devm_gpiod_get_index_optional() call. This driver has supported passing a LDO enable GPIO for years, yet this facility has never been put to use in the upstream kernel. If someone desires to put in place GPIO control for the LDOs, this can be done by adding a GPIO descriptor table in the MFD nexus in drivers/mfd/lp8788.c for the LDO device when spawning the MFD children, or using a board file.

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

When AXP806 support was added, POK was incorrectly expanded to PWROK. However, the datasheet lists them as POK[LSNP], which is the same as on the AXP288. Furthermore, the registers associated with POK functions are the same as the PEK on the other AXP PMICs. This suggests that "POK" means "Power On Key", much like "PEK" means "Power Enable Key", instead of "Power OK". This patch changes the "PWROK" prefix to "POK" for these interrupts.

Now GPIOD has support for both pdata systems and for non-standard DT bindings the Arizona reset GPIO can be converted to use it. Worth noting gpiod_set_raw_value_cansleep is used to match the behaviour of the old GPIOs. This is because the part is fairly widely used and it is unknown how many DTs are correctly setting active low through device tree, so to avoid breaking any existing users it is best to match the previous behaviour.

Using input prescaler, capture unit will trigger DMA once every configurable /2, /4 or /8 events (rising edge). This helps improve period (only) capture accuracy at high rates.

Add support for PMW input mode on pwm-stm32. STM32 timers support period and duty cycle capture as long as they have at least two PWM channels. One capture channel is used for period (rising-edge), one for duty-cycle (falling-edge). When there's only one channel available, only period can be captured. Duty-cycle is simply zero'ed in such a case. Capture requires exclusive access (e.g. no pwm output running at the same time, to protect common prescaler). Timer DMA burst mode (from MFD core) is being used, to take two snapshots of capture registers (upon each period rising edge).

STM32 Timers can support up to 7 DMA requests: - 4 channels, update, compare and trigger. Optionally request part, or all DMAs from stm32-timers MFD core. Also add routine to implement burst reads using DMA from timer registers. This is exported. So, it can be used by child drivers, PWM capture for instance (but not limited to).

The AB8540 was an evolved version of the AB8500, but it was never mass produced or put into products, only reference designs exist. The upstream support was never completed and it is unlikely that this will happen so drop the support for now to simplify maintenance of the AB8500.
