From 817bb7fbfb0a1ad5f9d475cef0752d4ec5fdeac2 Mon Sep 17 00:00:00 2001 From: AnilKumar Ch Date: Mon, 13 Aug 2012 20:36:05 +0530 Subject: mfd: Move tps65217 regulator plat data handling to regulator Regulator platform data handling was mistakenly added to MFD driver. So we will see build errors if we compile MFD drivers without CONFIG_REGULATOR. This patch moves regulator platform data handling from TPS65217 MFD driver to regulator driver. This makes MFD driver independent of REGULATOR framework so build error is fixed if CONFIG_REGULATOR is not set. drivers/built-in.o: In function `tps65217_probe': tps65217.c:(.devinit.text+0x13e37): undefined reference to `of_regulator_match' This patch also fix allocation size of tps65217 platform data. Current implementation allocates a struct tps65217_board for each regulator specified in the device tree. But the structure itself provides array of regulators so one instance of it is sufficient.

Fix it by removing all the checks for iTCO_wdt to keep the same behavior as 3.4 kernel. https://bugzilla.kernel.org/show_bug.cgi?id=44991 Actually the same check could be removed for the gpio-ich in lpc_ich.c, but I'm not sure if it will cause problems.

This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

It can happen that the ACPI BIOS wants to make use of pins in one group, preventing the OS to access these. This does not prevent the OS from accessing the other group(s). This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS wants to control GPIO 18 (group 1), while I (the OS) need to control GPIO 52 and 53 (group 2) for SMBus multiplexing. So instead of checking for ACPI resource conflict on the whole I/O range, check on a per-group basis, and consider it a success if at least one of the groups is available for the OS to use.

However, the IRQ base is not always used anymore since we can make use of Linear domains. It's better to use the AB8500 hwirq -> virq mapping helper function to convert them instead. That's what we do here.

For sharing information such like the virtual IRQ number, MFD core driver uses the resource structure. Then each module can retrieve the specific IRQ number and detect it in the IRQ thread.

The device supports a keyboard +scan matrix of 23x8. The device is connected to a Master +via the SMSC BC-Link interface or via the SMBus. +Keypad scan Input(KSI) and Keypad Scan Output(KSO) signals +are multiplexed with GPIOs. + +Interrupt generation +-------------------- + +Interrupts can be generated by an edge detection on a GPIO +pin or an edge detection on one of the bus interface pins. +Interrupts can also be detected on the keyboard scan interface. +The bus interrupt pin (BC_INT# or SMBUS_INT#) is asserted if +any bit in one of the Interrupt Status registers is 1 and +the corresponding Interrupt Mask bit is also 1. + +In order for software to determine which device is the source +of an interrupt, it should first read the Group Interrupt Status Register +to determine which Status register group is a source for the interrupt. +Software should read both the Status register and the associated Mask register, +then AND the two values together. Bits that are 1 in the result of the AND +are active interrupts. Software clears an interrupt by writing a 1 to the +corresponding bit in the Status register. + +Communication Protocol +---------------------- + +- SMbus slave Interface + The host processor communicates with the ECE1099 device + through a series of read/write registers via the SMBus + interface. SMBus is a serial communication protocol between + a computer host and its peripheral devices. The SMBus data + rate is 10KHz minimum to 400 KHz maximum + +- Slave Bus Interface + The ECE1099 device SMBus implementation is a subset of the + SMBus interface to the host. The device is a slave-only SMBus device. + The implementation in the device is a subset of SMBus since it + only supports four protocols. + + The Write Byte, Read Byte, Send Byte, and Receive Byte protocols are the + only valid SMBus protocols for the device. + +- BC-LinkTM Interface + The BC-Link is a proprietary bus that allows communication + between a Master device and a Companion device. The Master + device uses this serial bus to read and write registers + located on the Companion device. The bus comprises three signals, + BC_CLK, BC_DAT and BC_INT#. The Master device always provides the + clock, BC_CLK, and the Companion device is the source for an + independent asynchronous interrupt signal, BC_INT#. The ECE1099 + supports BC-Link speeds up to 24MHz. diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index 6bfa2a1ec9df..ae511b738441 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -375,6 +375,18 @@ config MFD_T7L66XB help Support for Toshiba Mobile IO Controller T7L66XB +config MFD_SMSC + bool "Support for the SMSC ECE1099 series chips" + depends on I2C=y + select MFD_CORE + select REGMAP_I2C + help + If you say yes here you get support for the + ece1099 chips from SMSC. + + To compile this driver as a module, choose M here: the + module will be called smsc. + config MFD_TC6387XB bool "Support Toshiba TC6387XB" depends on ARM && HAVE_CLK diff --git a/drivers/mfd/Makefile b/drivers/mfd/Makefile index 33c0e49f7e60..d8ccb630ddb0 100644 --- a/drivers/mfd/Makefile +++ b/drivers/mfd/Makefile @@ -76,6 +76,7 @@ obj-$(CONFIG_EZX_PCAP) += ezx-pcap.o obj-$(CONFIG_MCP) += mcp-core.o obj-$(CONFIG_MCP_SA11X0) += mcp-sa11x0.o obj-$(CONFIG_MCP_UCB1200) += ucb1x00-core.o +obj-$(CONFIG_MFD_SMSC) += smsc-ece1099.o obj-$(CONFIG_MCP_UCB1200_TS) += ucb1x00-ts.o ifeq ($(CONFIG_SA1100_ASSABET),y) diff --git a/drivers/mfd/smsc-ece1099.c b/drivers/mfd/smsc-ece1099.c new file mode 100644 index 000000000000..24ae3d8421c5 --- /dev/null +++ b/drivers/mfd/smsc-ece1099.c @@ -0,0 +1,113 @@ +/* + * TI SMSC MFD Driver + * + * Copyright (C) 2012 Texas Instruments Incorporated - http://www.ti.com + * + * Author: Sourav Poddar + * + * This program is free software;
