| bool "Qualcomm Single-wire Serial Bus Interface (SSBI)" |
| help |
| If you say yes to this option, support will be included for the |
| built-in SSBI interface on Qualcomm MSM family processors. |
| |
| This is required for communicating with Qualcomm PMICs and |
| other devices that have the SSBI interface. |

| config SPS |
| bool "SPS support" |
| select GENERIC_ALLOCATOR |
| help |
| The SPS (Smart Peripheral Switch) is a DMA engine. |
| It can move data in the following modes: |
| 1. Peripheral-to-Peripheral. |
| 2. Peripheral-to-Memory. |
| 3. Memory-to-Memory. |

| config USB_BAM |
| boolean "USB BAM Driver" |
| depends on SPS && USB_GADGET |
| help |
| Enabling this option adds USB BAM Driver. |
| USB BAM driver was added to supports SPS Peripheral-to-Peripheral |
| transfers between the USB and other peripheral. |
| |
| config SPS_SUPPORT_BAMDMA |
| bool "SPS support BAM DMA" |
| depends on SPS |
| default n |
| help |
| The BAM-DMA is used for Memory-to-Memory transfers. |
| The main use cases is RPC between processors. |
| The BAM-DMA hardware has 2 registers sets: |
| 1. A BAM HW like all the peripherals. |
| 2. A DMA channel configuration (i.e. channel priority). |
| |

| help |
| No-Data-Path BAM is used to improve BAM performance. |

| depends on SPMI |
| depends on OF_SPMI |
| tristate "Qualcomm QPNP LPG/PWM support" |
| help |
| This driver supports PWM/LPG devices in Qualcomm PMIC chips which |
| comply with QPNP. QPNP is a SPMI based PMIC implementation. These |
| devices support Pulse Width Modulation output with user generated |
| patterns. They share a lookup table with size of 64 entries. |
| |
| config QPNP_POWER_ON |
| tristate "QPNP PMIC POWER-ON Driver" |
| depends on OF_SPMI && SPMI && MSM_QPNP_INT |
| help |
| This driver supports the power-on functionality on Qualcomm |
| PNP PMIC. It currently supports reporting the change in status of |
| the KPDPWR_N line (connected to the power-key). |
| |
| config QPNP_CLKDIV |
| tristate "QPNP PMIC clkdiv driver" |
| depends on OF_SPMI && SPMI |
| help |
| This driver supports the clkdiv functionality on the Qualcomm |
| PNP PMIC. It configures the frequency of clkdiv outputs on the |
| PMIC. These clocks are typically wired through alternate functions |
| on gpio pins. |
| |
| config IPA |
| tristate "IPA support" |
| depends on SPS |
| help |
| This driver supports the Internet Packet Accelerator (IPA) core. |
| IPA is a programmable protocol processor HW block. |
| It is designed to support generic HW processing of UL/DL IP packets |
| for various use cases independent of radio technology. |
| The driver support client connection and configuration |
| for the IPA core. |
| Kernel and user-space processes can call the IPA driver |
| to configure IPA core. |
