The registers header file adds two new chip variant IDs defined in DA9061 and DA9062 hardware. The core header file adds new software enumerations for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration for distinguishing between DA9061/62 devices in software. The core source code adds a new .compatible of_device_id entry. This is extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The .data entry now holds a reference to the enumerated device type. A new regmap_irq_chip model is added for DA9061 and this supports the new list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the new sub system components for DA9061. Support is added for a new DA9061 regmap_config which lists the correct readable, writable and volatile ranges for this chip. The probe function uses the device tree compatible string to switch on the da9062_compatible_types and configure the correct mfd cells, irq chip and regmap config. Kconfig is updated to reflect support for DA9061 and DA9062 PMICs. Signed-off-by: Steve Twiss --- This patch applies against linux-next and v4.9 v4 -> v5 - NO CODE CHANGE - Rebased from v4.8 to v4.9 v3 -> v4 - Patch renamed from [PATCH V3 5/9] to [PATCH V4 4/8] - Removed DEFINE_RES_NAMED() macros for DA9061 resources and replaced them with DEFINE_RES_IRQ_NAMED(). - Removed whitespace - Reverted change for badly defined mfd_cell da9062_devs of_compatible string from "dlg,da9062-watchdog" back to "dlg,da9062-wdt" v2 -> v3 - NO CODE CHANGE - Patch renamed from [PATCH V2 05/10] to [PATCH V3 5/9] v1 -> v2 - Patch renamed from [PATCH V1 01/10] to [PATCH V2 05/10] -- these changes were made to fix checkpatch warnings caused by the patch set dependency order - Fixed typo in the commit message "readble" to "readable" - Removed the explicit cross-check to decide if there is a conflict between the device tree compatible string and the hardware definition. This patch assumes the device tree is correctly written and therefore removes the need for a hardware/DT sanity check. - Removed extra semicolon in drivers/mfd/da9062-core.c:877 - Re-write compatible entries into numerical order Lee, Changes as described in the version history above. As previously: This patch adds support for the DA9061 PMIC. This is done as part of the existing DA9062 device driver by extending the of_device_id match table. This in turn allows new MFD cells, irq chip and regmap definitions to support DA9061.
