* | regulator: mt6358: Add missing regulators for MT6366Chen-Yu Tsai2023-10-021-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When support for the MT6366 PMIC regulators was added, it was assumed that it had the same functionality as MT6358. In reality there are differences. A few regulators have different ranges, or were renamed and repurposed, or removed altogether. Add the 3 regulators that were missing from the original submission. These are added for completeness. VSRAM_CORE is not used in existing projects. VM18 and VMDDR feed DRAM related consumers, and are not used in-kernel.

* | regulator: mt6358: Add output voltage fine tuning to fixed regulatorsChen-Yu Tsai2023-09-251-0/+6
|/ | | | | | | | | | | | | | | | | The "fixed" LDO regulators found on the MT6358 and MT6366 PMICs have either no voltage selection register, or only one valid setting. However these do have a fine voltage calibration setting that can slightly boost the output voltage from 0 mV to 100 mV, in 10 mV increments. Add support for this by changing these into linear range regulators. Some register definitions that are missing are also added.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some configurations differ between chip variants, e,g. the register to control the on of state of LDOA1 and SWB2. Thus, it is necessary to choose the correct configuration for a dedicated device. If the wrong configuration was used, the LDOA1 output that was disabled by the bootloader was enabled in Kernel again. Each chip variant gets its dedicated configuration selected by the chip ID previously collected from MFD probe function. The VTT enum value (tps65086_regulators) is shifted because not all chip variants have a separate SWB2 switch. Sometimes they are merged. So the configuration possibilities differ, thus the regulator configuration arrays have a different length.

| * mfd: intel-m10-bmc: Manage access to MAX 10 fw handshake registersIlpo Järvinen2023-06-151-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some MAX 10 cards, the BMC firmware is not available to service handshake registers during secure update erase and write phases at normal speeds. This problem affects at least hwmon driver. When the MAX 10 hwmon driver tries to read the sensor values during a secure update, the reads are slowed down (e.g., reading all D5005 sensors takes ~24s which is magnitudes worse than the normal <0.02s). Manage access to the handshake registers using a rw semaphore and a FW state variable to prevent accesses during those secure update phases and return -EBUSY instead. If handshake_sys_reg_nranges == 0, don't update bwcfw_state as it is not used. This avoids the locking cost.

The high impedance mask RT5033_RT_HZ_MASK is actually value 0x02 [3] and is assosiated to the RT5033 CHGCTRL1 register [4]. Accordingly also change RT5033_CHARGER_HZ_ENABLE to 0x02 to avoid the need of a bit shift upon application. For input current limiting AICR mode, the define for the 1000 mA step was missing [5]. Additionally add the define for DISABLE option. Concerning the mask, remove RT5033_AICR_MODE_MASK because there is already RT5033_CHGCTRL1_IAICR_MASK further up. They are redundant and the upper one makes more sense to have the masks of a register colleted there as an overview.

It appears this happens because the OMAP driver now allocates GPIO numbers dynamically, so all that is references by number is a bit up in the air. Let's bite the bullet and try to just move the gpio_chip in the tps65010 MFD driver over to using dynamic allocations. Alter everything in the OSK1 board file to use a GPIO descriptor table and lookups. Utilize the NULL device to define some board-specific GPIO lookups and use these to immediately look up the same GPIOs, convert to IRQ numbers and pass as resources to the devices. This is ugly but should work. The .setup() callback for tps65010 was used for some GPIO hogging, but since the OSK1 is the only user in the entire kernel we can alter the signatures to something that is helpful and make a clean transition.

There were no code changes, just some tiny context differences due to the rebase, plus I added the newly gained tags.

The name AXP1530 seems to appear as well, and this is what is used in the BSP driver. From all we know it's the same chip, just a different name. However we have only seen AXP313a chips in the wild, so go with this name. Compared to the other AXP PMICs it's a rather simple affair: just three DCDC converters, three LDOs, and no battery charging support. Describe the regmap and the MFD bits, along with the registers exposed via I2C. Aside from the various regulators, also describe the power key interrupts, and adjust the shutdown handler routine to use a different register than the other PMICs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PWM capture assumes that the input selector is set to default input and that the slave mode is disabled. Force reset state for TISEL and SMCR registers to match this requirement. Note that slave mode disabling is not a pre-requisite by itself for capture mode, as hardware supports it for PWM capture. However, the current implementation of the driver does not allow slave mode for PWM capture. Setting slave mode for PWM capture results in wrong capture values.

Describe the regmap and the MFD bits, along with the registers exposed via I2C. Eventually advertise the device using a new compatible string and add support for power off the system. The driver would disable PEK function if IRQ is not configured in device tree, since some boards (For example, Starfive Visionfive 2) didn't connect IRQ line of PMIC to SOC. GPIO function isn't enabled in this commit, since its configuration operation is different from any existing AXP PMICs and needs logic modification on existing driver. GPIO support might come in later patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RZ/G2L multi-function timer pulse unit 3 (MTU3a) is embedded in the Renesas RZ/G2L family SoCs. It consists of eight 16-bit timer channels and one 32-bit timer channel. It supports the following functions - Counter - Timer - PWM The 8/16/32 bit registers are mixed in each channel. Add MTU3a core driver for RZ/G2L SoC. The core driver shares the clk and channel register access for the other child devices like Counter, PWM and Clock event.
