* mfd: rc5t583: Use devm_mfd_add_devices and devm_request_threaded_irqLaxman Dewangan2016-05-091-9/+2
| | | | | | | | | | | Use devm_mfd_add_devices() for adding MFD child devices and devm_request_threaded_irq() for IRQ registration. This reduces the need of remove callback for removing MFD child devices and unregistering IRQ. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: Kill off set_irq_flags usageRob Herring2015-08-111-3/+1
| | | | | | | | | | | | | | | | | | | | | set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

* mfd: Delete non-required instances of include <linux/init.h>Paul Gortmaker2014-03-191-1/+0
| | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* mfd: rc5t583: Fix array subscript is above array boundsAxel Lin2012-11-261-1/+1
| | | | | | | | | | | | | | | | | | | I got below build warning while compiling this driver. It's obviously RC5T583_MAX_INTERRUPT_MASK_REGS is 9 but irq_en_add array only has 8 elements. CC drivers/mfd/rc5t583-irq.o drivers/mfd/rc5t583-irq.c: In function 'rc5t583_irq_sync_unlock': drivers/mfd/rc5t583-irq.c:227: warning: array subscript is above array bounds drivers/mfd/rc5t583-irq.c: In function 'rc5t583_irq_init': drivers/mfd/rc5t583-irq.c:349: warning: array subscript is above array bounds Since the number of interrupt enable registers is 8, this patch adds define for RC5T583_MAX_INTERRUPT_EN_REGS to fix this bug.

* mfd: rc5t583: Fix warning messagesVenu Byravarasu2012-09-231-1/+1
| | | | | | | | | | | | | | | Two variables named master_int and sleepseq_val, were just declared without initialization. Pointers to these variables were passed to mfd read function. After that these variables were used for some of the logical operations. Though logically there is nothing wrong, compiler is complaining that the variables may be used uninitialized. Hence fixing these warning messages by initializing them. Signed-off-by: Venu Byravarasu <vbyravarasu@nvidia.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Ricoh power management IC RC5T583 contains is multi functional device having multiple sub devices inside this. This device has multiple dcdc/ldo regulators, gpios, interrupt controllers, on-key, RTCs, ADCs. This device have 4 DCDCs, 8 LDOs, 8 GPIOs, 6 ADCs, 3 RTCs etc. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
