Document a new Device Tree property 'samsung,s2mps11-wrstbi-ground' indicating that WRSTBI pin of S2MPS13 PMIC is pulled down so corresponding buck warm reset function should be disabled. Signed-off-by:

The WRSTBI bit (disabled by default but enabled by bootloader), when set, is responsible for resetting voltages to default values of certain bucks on falling edge of Warm Reset Input pin from AP. However on some boards (with S2MPS13) the pin is pulled down so any suspend will effectively trigger the reset of bucks supplying the power to the little and big cores. In the same time when resuming, these bucks must provide voltage greater or equal to voltage before suspend to match the frequency chosen by cpufreq. If voltage (default value of voltage after reset) is lower than one set by cpufreq before suspend, then system will hang during resuming. Signed-off-by:

There are different revisions of the same chipset. For example S2MPS13 has more than 2 revisions. They differ slightly in regulator constraints. Print the revision number to easily find which PMIC is used on the board. Signed-off-by:

In the case of a device tree config the code uses the device ID from the DT entry to check which codec is required but when storing the ID into struct arizona it was always using the non-DT SPI device table to get an ID. This patch changes the code to store the correct ID into struct arizona. Signed-off-by:

Remove the use of #ifdefs around each case statement of the chip ID and type validation switches. We must ensure that the contained code still compiles to nothing if support for that codec was not built into the kernel, to prevent creation of link references to missing functions. So the ifdefs are replaced with a use of the IS_ENABLED() macro. Signed-off-by:

The code was using a switch on the code type to execute one of several mfd_add_devices() calls. We're already switching on the code type earlier in the function to select the correct patch function so we can roll selection of the mfd device table into the same switch. Signed-off-by:

If the declared codec type doesn't match the detected type we issue a log message but carry on registering the device, so a dev_warn() is appropriate rather than a dev_err() Signed-off-by:

Currently runtime_suspend will fully power off the codec if the jack detection is not enabled. Not all future codecs will have jack detection so to prepare for these codecs this patch factors out the check so that it be called as needed in the existing codec-specific switch cases. Signed-off-by:

Currently DCVDD isolation is enabled and disabled for runtime_suspend and runtime_resume. Future codecs will not have the isolation control so to prepare for these codecs this patch factors out the isolation control allowing it to be called as needed in the existing codec-specific switch cases.

The driver depends on ARCH_NOMADIK but there isn't a build dependency so it's a good idea to allow the driver to always be built when the COMPILE_TEST option is enabled. That way, the driver can be built with a config generated by make allyesconfig and check if a patch would break the build. Signed-off-by:

Definitions for GPIO registers 8, 9, 10, 11, 12 and 13 are added into the register header file. - DA9052_GPIO_8_9_REG 25 - DA9052_GPIO_10_11_REG 26 - DA9052_GPIO_12_13_REG 27 A modification is also made to the MFD core code to define these registers as readable and writable. The functions for da9052_reg_readable() and da9052_reg_writeable() have had their case statements altered to include these new registers. Signed-off-by:

This driver supports the new Atmel Flexcom. The Flexcom is a wrapper which integrates one SPI controller, one I2C controller and one USART. Only one function can be enabled at a time. This driver selects the function once for all, when the Flexcom is probed, according to the value of the new "atmel,flexcom-mode" device tree property. This driver has chosen to present the Flexcom to the system as a MFD so the implementation is seamless for the existing Atmel SPI, I2C and USART drivers. Also the Flexcom embeds FIFOs: the latest patches of the SPI, I2C and USART drivers take advantage of this new feature. Signed-off-by:

The call to kstrtoul() will corrupt memory on 64 bit systems because an int is 4 bytes and a long is 8. Also it's not a good idea to let users trigger a dev_err() because it just ends up flooding /var/log/messages so I removed the printk.

tps6105 driver provides two cells. One is for GPIO and another one is for selected mode depending on platform data. When tps6105x is used in GPIO-only mode, this driver calls mfd_add_devices() with mfd_cell .name == NULL. This value causes an oops in platform_device_register() later. The following patch adds a mfd_cell for each possible mode thereby excluding .name assignment in runtime. Signed-off-by:

The lpc_ich_cells array gives the wrong impression about the relationship between the watchdog and GPIO devices. They are completely distinct devices, so this patch separates the array into distinct mfd_cell structs per device. A side effect of removing the array, is that the lpc_cells enum is no longer needed.
