Lars-Peter Clausen 6fcb8a3a3a mfd: Fix generic irq chip ack function name for jz4740-adc
In commit 659fb32d1b6("genirq: replace irq_gc_ack() with {set,clr}_bit
variants"), irq_gc_ack was renamed to irq_gc_ack_set_bit. The jz4740-adc
driver still uses the old name which results in a compile error.

Andres Salomon 6a54ac2149 mfd: mfd_cell is now implicitly available to jz4740 drivers
No need to explicitly set the cell's platform_data/data_size.

Modify clients to use mfd_get_cell helper function instead of
accessing platform_data directly.

Mark Brown 5af3bde8b2 mfd: Convert jz4740-adc to new irq_ methods
Convert the jz4740-adc driver to use the recently introduced IRQ API
variants which are passed struct irq_data rather than an IRQ number.

Lars-Peter Clausen 91f4debf5e mfd: Add JZ4740 ADC driver
This patch adds a MFD driver for the JZ4740 ADC unit. The driver is used to
demultiplex IRQs and synchronize access to shared registers between the
battery, hwmon and (future) touchscreen driver.
