Currently the driver requests the boot done and control interface IRQs before it has requested its own IRQ line.

2016-01-11mfd: as3722: Mark PM functions as __maybe_unusedArnd Bergmann1-2/+2
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.

2016-01-11mfd: syscon: Add a DT property to set value widthDamien Riegel1-0/+13
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.

2016-01-11mfd: cros ec: Lock the SPI bus while holding chipselectNicolas Boichat1-12/+18
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.

2015-12-04mfd: as3722: Handle interrupts on suspendJon Hunter1-0/+30
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.

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.

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.

2015-11-20serial: export fsl8250_handle_irqArnd Bergmann1-0/+1
fsl8250_handle_irq is now used by the of_serial driver, and that fails if it is a loadable module: ERROR: "fsl8250_handle_irq" [drivers/tty/serial/of_serial.ko] undefined!
