      mfd: davinci: Voicecodec needs regmap_mmio · 9e888487
      由 Arnd Bergmann 提交于 
      Without REGMAP_MMIO, building that driver results in a link error:

drivers/built-in.o: In function `davinci_vc_probe':
:(.init.text+0x3c1c): undefined reference to `devm_regmap_init_mmio_clk'

This adds a Kconfig 'select' statement as the usual way to ensure
that REGMAP_MMIO is enabled.

      mfd: STw481x: Allow modular build · f41716dc
      由 Arnd Bergmann 提交于 
      This driver depends on I2C, which may be a loadable module.
While you'd probably want both to be built-in in practice,
allowing a modular build avoids possible randconfig link
errors.

      mfd: UCB1x00: Enable modular build · 1c93c725
      由 Arnd Bergmann 提交于 
      The UCB1200 / UCB1300 driver uses the MCP_SA11X0 driver, which
can be a loadable module, but this results in a link error
when UCB1200 itself is built-in:

drivers/built-in.o: In function `ucb1x00_io_set_dir':
:(.text+0x4a364): undefined reference to `mcp_reg_write'
drivers/built-in.o: In function `ucb1x00_io_write':
:(.text+0x4a3dc): undefined reference to `mcp_reg_write'
drivers/built-in.o: In function `ucb1x00_io_read':
:(.text+0x4a400): undefined reference to `mcp_reg_read'
drivers/built-in.o: In function `ucb1x00_adc_enable':
:(.text+0x4a460): undefined reference to `mcp_enable'
...

This can easily be resolved by making CONFIG_MCP_UCB1200 itself
a tristate option, since that causes Kconfig to track the
dependency correctly.

      ARM: vexpress: refine dependencies for new code · b33cdd28
      由 Arnd Bergmann 提交于 
      The versatile express changes for 3.16 introduced a number of
build regressions for randconfig kernels by not tracking dependencies
between the components right.

This patch tries to rectify that:

* the mach-vexpress code cannot link without the syscfg driver,
  which in turn needs MFD_VEXPRESS_SYSREG
* various drivers call devm_regmap_init_vexpress_config(), which
  has to be exported so it can be used by loadable modules
* the configuration bus uses OF DT helper functions that are not
  available to platforms disable CONFIG_OF
* The sysreg driver exports GPIOs through gpiolib, which can
  be disabled on some platforms.
* The clocksource code cannot be built on platforms that don't
  use modern timekeeping but rely on gettimeoffset.

      mfd: vexpress: Define the device as MFD cells · 974cc7b9
      由 Pawel Moll 提交于 
      This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:

* LEDs code has been completely removed and replaced with
  "gpio-leds" nodes in the tree (referencing dedicated
  GPIO subnodes in sysreg - bindings documentation updated);
  this also better fits the reality as some variants of the
  motherboard don't have all the LEDs populated

* syscfg bridge code has been extracted into a separate
  driver (placed in drivers/misc for no better place)

* all the ID & MISC registers are defined as sysconf
  making them available for other drivers should they need
  to use them (and also to the user via /sys/kernel/debug/regmap
  which can be helpful in platform debugging)

      mfd: max77836: Add MAX77836 support to max14577 driver · aee2a57c
      由 Krzysztof Kozlowski 提交于 
      Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC
component so the extcon, charger and regulators are almost the same. The
MAX77836 however has also PMIC and Fuel Gauge.

The MAX77836 uses three I2C slave addresses and has additional interrupts
(related to PMIC and Fuel Gauge). It has also Interrupt Source register,
just like MAX77686 and MAX77693.

The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the
PMIC block. The PMIC block has different I2C slave address and uses own
regmap so another regmap_irq_chip is needed.

Since we have two regmap_irq_chip, use shared interrupts on MAX77836.

This patch adds additional defines and functions to the max14577 MFD core
driver so the driver will handle both chipsets. Also this patch replaces
"0x1 << N" with BIT(N) in defines for register masks.
