The mfd/s2mpa01.txt duplicates some of the information about bindings with old mfd/s2mps11.txt. Now common part exists entirely in mfd/samsung,sec-core.txt so: - add company prefix to file name (regulator/samsung,s2mpa01.txt), - remove duplicated information, - reorganize the contents to match style of regulator/samsung,s2mps11.txt.

Bindings for Samsung S2M and S5M family PMICs are in mess. They are spread over different files and subdirectories in a non-consistent way. The devices and respective drivers for them share a lot in common so everything could be organized in a more readable way. Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the drivers for this family of devices: - move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD driver (common for entire family), - split clock block to clock/samsung,s2mps11.txt, - split regulator block to regulator/samsung,s2mps11.txt.

As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1].

We do this by using the ret = !!(val) design pattern. This also start to propagate the negative error code from the smbus call if there is one, as the last commit of this series will make the gpiolib core deal with that properly. Signed-off-by:

Currently the driver requests the boot done and control interface IRQs before it has requested its own IRQ line. This can cause problems on edge triggered IRQ systems as if an edge occurs before the parent IRQ is enabled it will be missed. Whilst we are changing the error handling remove an unused label as well. Signed-off-by:

The newly introduced as3722_i2c_suspend/resume functions are built unconditionally, but only used when power management is enabled, so we get a warning otherwise: drivers/mfd/as3722.c:427:12: warning: 'as3722_i2c_suspend' defined but not used [-Wunused-function] drivers/mfd/as3722.c:438:12: warning: 'as3722_i2c_resume' defined but not used [-Wunused-function] This marks them both as __maybe_unused, which avoids an ugly #ifdef and gives us best compile-time coverage. When they are unused, the compiler will silently drop the functions from its output. Signed-off-by:

wm831x_unique_id_show currently displays an interesting pattern of '0' and '3' characters which isn't very useful (figuring out why is left as an exercise for the reader). Presumably "buf[i]" should have been "id[i] & 0xff". But while there, it is much simpler to simply use %phN and do all the formatting at once. Signed-off-by:

Currently syscon has a fixed configuration of 32 bits for register and values widths. In some cases, it would be desirable to be able to customize the value width. For example, certain boards (like the ones manufactured by Technologic Systems) have a FPGA that is memory-mapped, but its registers are only 16-bit wide. This patch adds an optional "reg-io-width" DT binding for syscon that allows to change the width for the data bus (i.e. val_bits). If this property is provided, it will also set the register stride to reg-io-width's value. If not provided, the default configuration is used. Signed-off-by:

cros_ec_cmd_xfer_spi and cros_ec_pkt_xfer_spi generally work like this: - Pull CS down (active), wait a bit, then send a command - Wait for response (multiple requests) - Wait a while, pull CS up (inactive) These operations, individually, lock the SPI bus, but there is nothing preventing the SPI framework from interleaving messages intended for other devices as the bus is unlocked in between. This is a problem as the EC expects CS to be held low for the whole duration. Solution: Lock the SPI bus during the whole transaction, to make sure that no other messages can be interleaved.

The as3722 device is registered as an irqchip and the as3722-rtc interrupt is one of it's interrupt sources. When using the as3722-rtc as a wake-up device from suspend, the following is seen: PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.001 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done. Suspending console(s) (use no_console_suspend to debug) PM: suspend of devices complete after 161.119 msecs PM: late suspend of devices complete after 1.048 msecs PM: noirq suspend of devices complete after 0.756 msecs Disabling non-boot CPUs ... CPU1: shutdown CPU2: shutdown CPU3: shutdown Entering suspend state LP1 Enabling non-boot CPUs ... CPU1 is up CPU2 is up CPU3 is up PM: noirq resume of devices complete after 0.487 msecs as3722 4-0040: Failed to read IRQ status: -16 as3722 4-0040: Failed to read IRQ status: -16 as3722 4-0040: Failed to read IRQ status: -16 as3722 4-0040: Failed to read IRQ status: -16 ... The reason why the as3722 interrupt status cannot be read is because the as3722 interrupt is not masked during suspend and when the as3722-rtc interrupt occurs, to wake-up the device, the interrupt is seen before the i2c controller has been resumed in order to read the as3722 interrupt status. The as3722-rtc driver sets it's interrupt as a wake-up source during suspend, which gets propagated to the parent as3722 interrupt. However, the as3722-rtc driver cannot disable it's interrupt during suspend otherwise we would never be woken up and so the as3722 must disable it's interrupt instead. Fix this by disabling the as3722 interrupt during suspend. To ensure that a wake-up event from the as3722 is not missing, enable the as3722 interrupt as a wake-up source before disabling the interrupt on entering suspend. Signed-off-by:

The MFD part of wm8994 consists of three files wm8994-core.c, wm8994-irq.c and wm8994-regmap.c only wm8994-core.c has a MODULE_DESCRIPTION / LICENSE. These were clearly intended to be built as a single module, but currently are not. This will lead to a tainted kernel when loading modules for wm8894-irq.c and wm8994-regmap.c because are missing a license. This patch fixes this issue by grouping the three files together into a single module. Reported-by:

Currently S2MPSXX multifunction device is named as *-pmic, and these MFDs also supports regulator as a one of its MFD cell which has the same name, because current name is confusing and we want to sort it out. We did discussed different approaches about how the MFD and it cells need to be named here [1]. Based in the discussion this patch rename MFD regulator name as *-regulator instead of current *-pmic. This patch also changes the corresponding entries in the regulator driver to keep git-bisect happy. [1]-> https://lkml.org/lkml/2015/10/28/417Suggested-by:
