The BD72720 is designed to support using the BUCK10 as a supply for the LDOs 1 to 4. When the BUCK10 is used for this, it can be set to a LDON_HEAD mode. In this mode, the BUCK10 voltage can't be controlled by software, but the voltage is adjusted by PMIC to match the LDO1 .. LDO4 voltages with a given offset. Offset can be 50mV .. 300mV and is changeable at 50mV steps. Add 'ldon-head-microvolt' property to denote a board which is designed to utilize the LDON_HEAD mode. All other properties are already existing. Add dt-binding doc for ROHM BD72720 regulators to make it usable.

There are two different use-cases for this type of charging. At least some Li-Ion batteries can benefit from very slow, constant current, pre-pre phase 'trickle-charging', if a battery is very empty. Some other batteries use top-off phase 'trickle-charging', which is different from the above case. The battery bindings use the term 'trickle-charge' without specifying which of the use-cases properties are addressing. This has already caused some confusion. Clarify that the 'trickle-charge-current-microamp' refers to the first one, the "pre-pre" -charging use-case.

This relies on battery specific "VDR" (voltage drop rate) tables, which are measured from the battery, and which describe the voltage drop rate. More thorough explanation about the "zero correction" and "VDR" parameters is here: https://lore.kernel.org/all/676253b9-ff69-7891-1f26-a8b5bb5a421b@fi.rohmeur= ope.com/ Document the VDR zero-correction specific battery properties used by the BD71815, BD71828, BD72720 and some other ROHM chargers.

(Add table of temperatures and use number matching the right temperature index in the VDR table name). - Fix typoed 'algorithm' in commit message. The parameters are describing the battery voltage drop rates - so they are properties of the battery, not the charger. Thus they do not belong in the charger node. The right place for them is the battery node, which is described by the generic "battery.yaml". There were some discussion whether these properties should be in their own file, or if they should be added to battery.yaml. Discussion can be found from: https://lore.kernel.org/all/52b99bf7-bfea-4cee-aa57-4c13e87eaa0d@gmail.com/ This patch implements the volt-drop properties as generic (not vemdor specific) properties in the battery.yaml. It's worth noting that these properties are: - Meaningful only for those charger drivers which have the VDR algorithm implemented. (And even though the algorithm is not charger specific, AFAICS, it is currently only used by some ROHM PMIC drivers). - Technique of measuring the VDR tables for a battery is not widely known. AFAICS, only folks at ROHM are measuring those for some customer products. We do have those tables available for some of the products, like Kobo e-readers though. --- .../bindings/power/supply/battery.yaml | 22 +++++++++++++++++++ 1 file changed, 22 insertions(+) diff --git a/Documentation/devicetree/bindings/power/supply/battery.yaml b/= Documentation/devicetree/bindings/power/supply/battery.yaml index d1a2080557a0..8ebf05d9497c 100644 --- a/Documentation/devicetree/bindings/power/supply/battery.yaml +++ b/Documentation/devicetree/bindings/power/supply/battery.yaml @@ -128,6 +128,21 @@ properties: - description: alert when battery temperature is lower than this val= ue - description: alert when battery temperature is higher than this va= lue =20 + # The volt-drop* -properties describe voltage-drop for a battery, descri= bed + # as VDROP in: + # https://patentimages.storage.googleapis.com/6c/f5/17/c1d901c220f6a9/US= 20150032394A1.pdf + volt-drop-thresh-microvolt: + description: Threshold for starting the VDR correction + maximum: 48000000 + + volt-drop-soc-bp: + description: Table of capacity values matching the values in VDR table= s. + The value should be given as basis points, 1/100 of a percent. + + volt-drop-temperatures-millicelsius: + description: An array containing the temperature in milli celsius, for= each + of the VDR lookup table. + required: - compatible =20 @@ -146,6 +161,13 @@ patternProperties: - description: battery capacity percent maximum: 100 =20 + '^volt-drop-[0-9]-microvolt': + description: Table of the voltage drop rate (VDR) values.

These are handled identically to the existing bd71828-grnled and bd71828-ambled and should be removed from the driver. Thus they are not documented in the binding document. Furthermore, the BD72720 Linux driver does not use the compatible property from the LED node. The Linux driver is load and probed based on the PMIC compatible in the MFD node.

Similarly to the BD71815 and BD71828, the BD72720 integrates regulators, charger, RTC, clock gate and GPIOs. The main difference to the earlier PMICs is that the BD72720 has two different I2C slave addresses. In addition to the registers behind the 'main I2C address', most of the charger (and to some extent LED) control is done via registers behind a 'secondary I2C slave address', 0x4c. Signed-off-by: Matti Vaittinen --- Revision history: v5 =3D> v6: - Plenty of styling fixes as suggested by Lee - Add a define for the register offset 0x100 - use ERR_CAST() v2 =3D>: - no changes RFCv1 =3D> v2: (Mostly addressed comments from Lee and Andreas) - Use stacked regmaps to avoid platform data and the tango with multiple regmaps in the power-supply driver - Use regmap_reg_range() - make it clear bd72720_irq_type_base is an array - tab-out definitions in the bd72720 header - minor styling Note: This patch depends on the series: "power: supply: add charger for BD71828" by Andreas: https://lore.kernel.org/all/20250918-bd71828-charger-v5-0-851164839c28@kemn= ade.info/ There are some new variants being planned. Most notably, the BD73900 should be almost identical to the BD72720 - for everything else except the charger block. --- drivers/mfd/Kconfig | 18 +- drivers/mfd/rohm-bd71828.c | 490 +++++++++++++++++++++++- include/linux/mfd/rohm-bd72720.h | 634 +++++++++++++++++++++++++++++++ include/linux/mfd/rohm-generic.h | 1 + 4 files changed, 1129 insertions(+), 14 deletions(-) create mode 100644 include/linux/mfd/rohm-bd72720.h diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index 6cec1858947b..80c5d1753908 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -2211,20 +2211,22 @@ config MFD_ROHM_BD718XX and emergency shut down as well as 32,768KHz clock output. =20 config MFD_ROHM_BD71828 - tristate "ROHM BD71828 and BD71815 Power Management IC" + tristate "ROHM BD718[15/28/79], BD72720 and BD73900 PMICs" depends on I2C=3Dy depends on OF select REGMAP_I2C select REGMAP_IRQ select MFD_CORE help - Select this option to get support for the ROHM BD71828 and BD71815 - Power Management ICs.

It makes sense to support the regulator control for both PMICs using the same driver. It is often more clear to have the IC specific functions and globals named starting with the chip-name. So, as a preparatory step, prefix the BD71828 specific functions and globals with the bd71828. It would be tempting to try also removing the chip ID from those functions which will be common for both PMICs. I have bad experiences on this as it tends to lead to problems when yet another IC is being supported with the same driver, and we will have some functions used for all, some for two of the three, and some for just one. At this point I used to start inventing wildcards like BD718XX or BD7272X. This approach is pretty much always failing as we tend to eventually have something like BD73900 - where all the wildcard stuff will break down. So, my approach these days is to: - keep the original chip-id prefix for anything that had it already (and avoid the churn). - use same prefix for all things that are used by multiple ICs - typically the chip-ID of the first chip. This typically matches also the driver and file names. - use specific chip-ID as a prefix for anything which is specific to just one chip. As a preparatory step to adding the BD72720, add bd71828 prefix to all commonly usable functions and globals.

This PMIC has plenty of commonalities with the BD71828 and BD71879. The BD72720 does also have similar 'run-level'-concept as the BD71828 had. It allows controlling the regulator's 'en masse', although only BUCK1 and LDO1 can utilize this in BD72720. Similar to BD71828, this 'en masse' -control is not supported by this driver. Support the voltage and enable/disable state control for the BD72720. Signed-off-by: Matti Vaittinen Reviewed-by: Mark Brown --- Revision history: v3 =3D>: - No changes v2 =3D> v3: - The ldon-head dt-property was changed to microvolts. Adapt the driver to that RFCv1 =3D> v2: - No changes There are some new variants planned. Most notably, the BD73900 should be similar to the BD72720 what comes to the regulator control logic. If the run-level control is needed, there are some downstream extensions available at: https://rohmsemiconductor.github.io/Linux-Kernel-PMIC-Drivers/BD72720/ --- drivers/regulator/Kconfig | 8 +- drivers/regulator/bd71828-regulator.c | 993 +++++++++++++++++++++++++- 2 files changed, 992 insertions(+), 9 deletions(-) diff --git a/drivers/regulator/Kconfig b/drivers/regulator/Kconfig index d84f3d054c59..660863f096e3 100644 --- a/drivers/regulator/Kconfig +++ b/drivers/regulator/Kconfig @@ -241,13 +241,13 @@ config REGULATOR_BD71815 will be called bd71815-regulator. =20 config REGULATOR_BD71828 - tristate "ROHM BD71828 Power Regulator" + tristate "ROHM BD71828, BD72720 and BD73900 Power Regulators" depends on MFD_ROHM_BD71828 select REGULATOR_ROHM help - This driver supports voltage regulators on ROHM BD71828 PMIC. - This will enable support for the software controllable buck - and LDO regulators. + This driver supports voltage regulators on ROHM BD71828, + BD71879, BD72720 and BD73900 PMICs.

The GPIO1 ... GPIO5 and EPDEN pins. The configuration is done to OTP at the manufacturing, and it can't be read at runtime. The device-tree is required to tell the software which of the pins are used as GPIOs. Keep the pin mapping static regardless the OTP. This way the user-space can always access the BASE+N for GPIO(N+1) (N =3D 0 to 4), and BASE + 5 for the EPDEN pin. Do this by setting always the number of GPIOs to 6, and by using the valid-mask to invalidate the pins which aren't configured as GPIOs. First two pins can be set to be either input or output by OTP. Direction can't be changed by software. Rest of the pins can be set as outputs only. All of the pins support generating interrupts. Support the Input/Output state getting/setting and the output mode configuration (open-drain/push-pull).

The new BD72720 will use stacked register maps to hide paging which is done using secondary I2C slave address. This requires use of 9-bit register addresses in the power-supply driver (added offset 0x100 to the 8-bit hardware register addresses). The cost is slightly used memory consumption as the members in the struct pwr_regs will be changed from u8 to unsigned int, which means 3 byte increase / member / instance. This is currently 14 members (expected to possibly be increased when adding new variants / new functionality which may introduce new registers, but not expected to grow much) and 2 instances (will be 3 instances when BD72720 gets added). So, even if the number of registers grew to 50 it'd be 150 bytes / instance. Assuming we eventually supported 5 variants, it'd be 5 * 150 bytes, which stays very reasonable considering systems we are dealing with. As a side note, we can reduce the "wasted space / member / instance" from 3 bytes to 1 byte, by using u16 instead of the unsigned int if needed. I rather use unsigned int to be initially prepared for devices with 32 bit registers if there is no need to count bytes.

Due to the similarities it makes sense to support also the BD72720 with the same driver. Add basic support for the charger logic on ROHM BD72720.
