2017-04-27memory: atmel-ebi: Simplify SMC config codeBoris Brezillon2-303/+128
New helpers/macros have been to atmel-smc.h introduced to simplify SMC regs manipulation. Rework the code to use those helpers, and simplify the ->xlate_config(), ->get_config() and ->apply_config() implementations. SMC configs are now stored in a struct atmel_smc_cs_conf object that directly contains registers values, which should help implementing ->suspend()/->resume() hooks. We can also get rid of those regmap fields (and the associated ->init() hook) which are not longer needed thanks to the atmel_[h]smc_cs_conf_{apply,get}() helpers.

2017-04-27mfd: syscon: atmel-smc: Add new helpers to ease SMC regs manipulationBoris Brezillon4-0/+406
These new helpers + macro definitions are meant to replace the old ones which are unpractical to use. Note that the macros and function prefixes have been intentionally changed to ATMEL_[H]SMC_XX and atmel_[h]smc_ to reflect the fact that this IP is also embedded in avr32 SoCs (and not only in at91 ones).

2017-04-27mfd: palmas: Reset the POWERHOLD mux during power offKeerthy1-0/+14
POWERHOLD signal has higher priority over the DEV_ON bit. So power off will not happen if the POWERHOLD is held high. Hence reset the MUX to GPIO_7 mode to release the POWERHOLD and the DEV_ON bit to take effect to power off the PMIC. PMIC Power off happens in dire situations like thermal shutdown so irrespective of the POWERHOLD setting go ahead and turn off the powerhold. Currently poweroff is broken on boards that have powerhold enabled. This fixes poweroff on those boards. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2017-04-27mfd: tc6393xb: Make use of raw_spinlock variantsJulia Cartwright1-26/+26
The tc6393xb mfd driver currently implements an irq_chip for handling interrupts; due to how irq_chip handling is done, it's necessary for the irq_chip methods to be invoked from hardirq context, even on a a real-time kernel. Because the spinlock_t type becomes a "sleeping" spinlock w/ RT kernels, it is not suitable to be used with irq_chips. A quick audit of the operations under the lock reveal that they do only minimal, bounded work, and are therefore safe to do under a raw spinlock.

2017-04-27mfd: arizona: Refactor arizona_poll_regCharles Keepax1-20/+16
Currently, we specify the timeout in terms of the number of polls but it is more clear from a user of the functions perspective to specify the timeout directly in milliseconds, as such update the function to these new semantics. Additionally, arizona_poll_reg essentially hard-codes regmap_read_poll_timeout, update the implementation to use regmap_read_poll_timeout. We still keep arizona_poll_reg around as regmap_read_poll_timeout is a macro so rather than expand this for each caller keep it wrapped in arizona_poll_reg. Whilst we are doing this make the timeouts a little more generous as the previous system had a bit more slack as it was done as a delay per iteration of the loop whereas regmap_read_poll_timeout compares ktime's.

2017-04-27mfd: cros ec: spi: Increase wait time to 200msDoug Anderson1-3/+6
This is a sucky change to bump up the time we'll wait for the EC. Why is it sucky? If 200ms for a transfer is a common thing it will have a massively bad impact on keyboard responsiveness. It still seems like a good idea to do this, though, because we have a gas gauge that claims that in an extreme case it could stretch the i2c clock for 144ms. It's not a common case so it shouldn't affect responsiveness, but it can happen. It's much better to have a single slow keyboard response than to start returning errors when we don't have to. In newer EC designs we should probably implement a virtual battery to respond to the kernel to insulate the kernel from these types of issues.

2017-04-27mfd: Add TI LMU driverMilo Kim5-0/+640
TI LMU (Lighting Management Unit) driver supports lighting devices below. LM3532, LM3631, LM3632, LM3633, LM3695 and LM3697. LMU devices have common features. - I2C interface for accessing device registers - Hardware enable pin control - Backlight brightness control - Notifier for hardware fault monitoring - Regulators for LCD display bias It contains fault monitor, backlight, LED and regulator driver. LMU fault monitor ----------------- LM3633 and LM3697 provide hardware monitoring feature. It enables open or short circuit detection. After monitoring is done, each device should be re-initialized. Notifier is used for this case. Separate patch for 'ti-lmu-fault-monitor' will be sent later. Backlight --------- It's handled by TI LMU backlight consolidated driver and chip dependent data. Separate patchset will be sent later. LED indicator ------------- LM3633 has 6 indicator LEDs. Programmable dimming pattern is also supported. Separate patch for 'leds-lm3633' will be sent later. Regulator --------- LM3631 has 5 regulators for the display bias. LM3632 supports 3 regulators. One consolidated driver enables it. The lm363x regulator driver is already upstreamed.

commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot") was intended to fix the case where a board uses an AXP806 in slave mode, but the boot loader leaves it in master mode for lack of AXP806 support. But now the driver breaks on boards where the PMIC is operating in master mode. This patch lets the driver use the new device tree property "xpowers,master-mode" to set the correct operating mode for the board.
