The preferred way to implement SPI-NOR controller drivers is through SPI subsubsystem utilizing the SPI MEM core functions. This converts the Intel SPI flash controller driver over the SPI MEM by moving the driver from SPI-NOR subsystem to SPI subsystem and in one go make it use the SPI MEM functions.

2022-02-01mfd: intel_soc_pmic_chtwc: Add cht_wc_model data to struct intel_soc_pmicHans de Goede1-0/+8
Tablet / laptop designs using an Intel Cherry Trail x86 main SoC with an Intel Whiskey Cove PMIC do not use a single standard setup for the charger, fuel-gauge and other chips surrounding the PMIC / charging+data USB port. Unlike what is normal on x86 this diversity in designs is not handled by the ACPI tables. On 2 of the 3 known designs there are no standard (PNP0C0A) ACPI battery devices and on the 3th design the ACPI battery device does not work under Linux due to it requiring non-standard and undocumented ACPI behavior. So to make things work under Linux we use native charger and fuel-gauge drivers on these devices, re-using the native drivers used on ARM boards with the same charger / fuel-gauge ICs. This requires various MFD-cell drivers for the CHT-WC PMIC cells to know which model they are exactly running on so that they can e.g. instantiate an I2C-client for the right model charger-IC (the charger is connected to an I2C-controller which is part of the PMIC). Rather then duplicating DMI-id matching to check which model we are running on in each MFD-cell driver, add a check for this to the shared drivers/mfd/intel_soc_pmic_chtwc.c code by using a DMI table for all 3 known models: 1. The GPD Win and GPD Pocket mini-laptops, these are really 2 models but the Pocket re-uses the GPD Win's design in a different housing: The WC PMIC is connected to a TI BQ24292i charger, paired with a Maxim MAX17047 fuelgauge + a FUSB302 USB Type-C Controller + a PI3USB30532 USB switch, for a fully functional Type-C port. 2. The Xiaomi Mi Pad 2: The WC PMIC is connected to a TI BQ25890 charger, paired with a TI BQ27520 fuelgauge, using the TI BQ25890 for BC1.2 charger type detection, for a USB-2 only Type-C port without PD. 3. The Lenovo Yoga Book YB1-X90 / Lenovo Yoga Book YB1-X91 series: The WC PMIC is connected to a TI BQ25892 charger, paired with a TI BQ27542 fuelgauge, using the WC PMIC for BC1.2 charger type detection and using the BQ25892's Mediatek Pump Express+ (1.0) support to enable charging with up to 12V through a micro-USB port.

2021-12-15clk: Introduce clk-tps68470 driverHans de Goede1-0/+11
The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in the kernel the Regulators and Clocks are controlled by an OpRegion driver designed to work with power control methods defined in ACPI, but some platforms lack those methods, meaning drivers need to be able to consume the resources of these chips through the usual frameworks. This commit adds a driver for the clocks provided by the tps68470, and is designed to bind to the platform_device registered by the intel_skl_int3472 module. This is based on this out of tree driver written by Intel: https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/clk/clk-tps68470.c with various cleanups added.

2021-11-24regulator: rohm-generic: remove unused dummiesMatti Vaittinen1-14/+0
Function rohm_regulator_set_voltage_sel_restricted() and rohm_regulator_set_dvs_levels() had inlined dummy implementations for cases when the real implementation was not configured in. All of the drivers who issue the call to these functions do SELECT the real implementation from the Kconfig. There should be no cases where the real implementation was not selected by the drivers using these functions - such a situation is likely to be an error which deserves to be noticed at compile-time. These dummies could in theory be used for compile-testing the drivers only (without the generic rohm regulator pieces). However, for such compile testing we should manually drop the selection from KConfig - and I guess that if it does not work out-of-the-box, then it is not going to happen. Especially when there should be no reason to omit compile-testing the generic rohm_regulator part. Crash test dummies.

2021-10-21mfd: ti_am335x_tscadc: Introduce a helper to deal with the type of hardwareMiquel Raynal1-0/+6
One way of knowing which hardware we are dealing with is to check the compatible string. When this must be done at several places, it's best and certainly more clear to use a helper for that. Introduce ti_adc_with_touchscreen() to indicate if there is a touchscreen controller available (meaning it's an am33xx-like ADC). This helper does not indicate if it is actually used (that is the purpose of the use_tsc boolean). Introducing this helper helps making a difference in the code between what is generic to both types of ADCs and what is specific to the am33xx hardware before introducing support for the am437x hardware.

2021-10-21mfd: ti_am335x_tscadc: Drop useless definitions from the headerMiquel Raynal1-28/+16
Drop useless definitions from the header like the "masks" definitions which are only used by the following definition. It could be possible to got even further by removing these definitions entirely and use FIELD_PREP() macros from the code directly, but while I have no troubles making these changes in the header, changing the values in the code directly could darkening a bit the logic and hardening future git-blames for very little added value IMHO (but this is of course a personal taste). Certain macros are using GENMASK() to define the value of a particular field, while this is purely "by chance" that the value and the mask have the same value. In this case, drop the "mask" definition, use FIELD_PREP() and GENMASK() in the macro defining the field, and use the new macro to define the particular value by feeding directly the actual number advertised in the datasheet into that macro, as in: -#define STEPCONFIG_RFM_VREFN GENMASK(24, 23) -#define STEPCONFIG_RFM(val) FIELD_PREP(STEPCONFIG_RFM_VREFN, (val)) +#define STEPCONFIG_RFM(val) FIELD_PREP(GENMASK(24, 23), (val)) +#define STEPCONFIG_RFM_VREFN STEPCONFIG_RFM(3) Signed-off-by: Miquel Raynal <[email protected]> Reviewed-by: Jonathan Cameron <[email protected]> Signed-off-by: Lee Jones <[email protected]> Link: https://lore.kernel.org/r/[email protected]

Also included in here are the counter driver subsystem updates as the IIO drivers needed them. Lots of churn in some staging drivers, we dropped the "old" rtl8188eu driver and replaced it with a newer version of the driver that had been maintained out-of-tree by Larry with the end goal of actually being able to get this driver out of staging eventually. Despite that driver being "newer" the line count of this pull request is going up. Some drivers moved out of staging as well, which is always nice to see, that is why there are additions to the mfc and misc driver subsystems. All of these were acked by the various subsystem maintainers involved. But by far, as normal, it's coding style cleanups all over the drivers/staging/ tree in here. Full details of these changes are in the shortlog. All of these have been in linux-next for a while with no reported problems" [ Note: the r8188eu merge clashed with commit 89939e890605 ("staging: rtlwifi: use siocdevprivate") from the networking tree.
