This is hardware layout for access PMIC MT6397 from AP SoC MT8135. Between PMIC MT6397 and MT8135, the physical signal channel is SPI bus. A specific hardware called PMIC Wrapper or PWRAP to handle access protocols in both PMIC and AP side. +-----------------+ +---------------+ | | | | | Mediatek AP SoC | | | | (ex. MT8135) | | MT6397 | | | | | | +--------+ | (SPI bus) | +--------+ | | | | |-----------| | | | | | PMIC | |-----------| | PMIC | | | | Wrapper| |-----------| | Wrapper| | | | | |-----------| | | | | +--------+ | | +--------+ | | | | | +-----------------+ +---------------+ Changes since v2 ================ (1) Patch 1/8: Update kernel config of MT8135 PMIC Wrapper. It needs to select REGMAP. (2) Patch 2/8: Update patch of MT6397 MFD driver to fix defeat of coding styles. (3) Patch 3/8: Update MT6397 regulator driver - use standard helpers for ops ".set_voltage_sel", ".get_voltage_sel" and ".is_enabled" - remove regulator's DT matching codes in the driver. - fix defeat of coding styles. (4) Patch 4/8: Update document for MT8135 PMIC wrapper. (5) Patch 5/8: Update document for MT6397 MFD. (6) Patch 6/8: Update document for MT6397 regulators. (7) Patch 7/8: Update device tree for MT8135 PMIC wrapper in mt8135.dtsi. (8) Patch 8/8: Add device tree for MT6397 MFD and regulators in mt8135-evbp1.dts board file. Second version (v2): http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/307069.html Changes since v1 ================ (1) Patch 1/8: Add MT8135 PMIC wrapper driver for SoC's proprietary hardware. (2) Patch 2/8: Update patch of MT6397 MFD driver to contain only MFD related codes and fix defeat of coding styles. (3) Patch 3/8: Update MT6397 regulator driver - use helpers and standard ways for specifying data in regulator description. - add more comments to explaining why the driver implement its own regulator_ops for ".is_enabled", ".set_voltage_sel" and ".get_voltage_sel". - update driver implement for coding styles. (4) Patch 4/8: Add document for MT8135 PMIC wrapper. (5) Patch 5/8: Update document for MT6397 MFD. (6) Patch 6/8: Update document for MT6397 regulators. (7) Patch 7/8: Add device tree for MT6397 MFD in mt8135.dtsi. (8) Patch 8/8: Update device tree for MT6397 regulators in mt8135.dtsi. Initial version (v1): http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/302984.html This driver is based on 3.18-rc1.
