* bus: arm-ccn: Fix error handling at event allocationPawel Moll2014-08-011-4/+5
| | | | | | | | | | | | | The bitfield allocation function returns error condition as a negative value, but in two cases its result was assigned to an unsigned member of the hw_perf_event structure, thus the error would not be ever detected. Fixed by using an intermediate, signed variable. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Pawel Moll <pawel.moll@arm.com> Signed-off-by: Olof Johansson <olof@lixom.net>

Mostly to remove broken legacy code for omap1 and move things towards device tree. These patches were posted a while back, but I did not realize I was supposed to merge the driver related parts too.

| * mailbox/omap: add a parent structure for every IP instanceSuman Anna2014-07-291-58/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new structure, omap_mbox_device, is added to contain the global variables pertinent to a mailbox h/w IP block. This enables the support for having multiple instances of the same h/w IP block in the SoC. This is in preparation to support the DRA7 SoC, which is the first SoC in the OMAP family to have multiple mailbox IP instances. The changes include enhancements to the sub-mailbox registration logic and mbox startup sequencing, removing the usage of single global configuration variables for all h/w instances, and storing the registered sub-mailboxes with the parent mailbox device structure.

| * mailbox/omap: remove the private mailbox structureSuman Anna2014-07-291-63/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The structure omap_mbox_priv is used previously to store arch specific (OMAP1 vs OMAP2+) data, and is no longer required to be maintained separately. Instead, absorb its elements into either the sub-mailbox device structure, omap_mbox, or the individual fifo descriptor structure, omap_mbox_fifo. The newmsg_bit and notfull_bit used on Rx and Tx fifos respectively are represented by the new intr_bit field in the fifo descriptor structure. The interrupt configuration registers are also moved into the fifo descriptor structure to allow the Rx and Tx fifos to use different interrupt lines/users.

| * mailbox/omap: consolidate OMAP mailbox driverSuman Anna2014-07-295-455/+283Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need for a separate common OMAP mailbox module now that the OMAP1 mailbox driver has been removed. So, consolidate the two individual OMAP mailbox modules into a single driver. This streamlines the driver for converting to mailbox framework. The following are the main changes: - collapse mailbox-omap2.c into omap-mailbox.c - remove omap_mbox_ops and replace the ops calls with the equivalent functionality. - simplify the sub-mailbox startup/shutdown functionality, the one-time operations are moved into probe, and the pm_runtime_get_sync and pm_runtime_put_sync can be invoked without using a configuration counter. - move all definitions from private omap_mbox.h into the source code, and eliminate this internal header. - rename some variables that used the omap2_mbox prefix with a generic omap_mbox prefix.

Add the DT nodes for all these 13 mailboxes. Except for mailbox 1, all other mailboxes do not have interrupts mapped into the MPU GIC by default. All the mailboxes have been disabled and the interrupts property information is left out intentionally for now, because of the dependencies against the crossbar driver.

All concerned maintainer gave their acknowledgement to the relevant patches. At the end, it removes three obsolete drivers and the diffstat looks pretty nice as well." Atmel PWM driver update for 3.17 - move to the new PWM driver which uses PWM framework - remove 3 obsolete drivers (atmel-pwm-bl.c, leds-atmel-pwm.c and atmel_pwm.c) * tag 'at91-drivers' of git://github.com/at91linux/linux-at91: misc: atmel_pwm: remove obsolete driver leds: atmel-pwm: remove obsolete driver backlight: atmel-pwm-bl: remove obsolete driver avr32: update defconfig to use the generic PWM framework avr32: favr-32: use generic pwm_bl driver avr32: merisc: use generic leds_pwm driver avr32: MRMT: use generic leds_pwm driver avr32/at32ap: switch to the generic PWM framework PWM: atmel: allow building for AVR32 ARM: at91: remove useless at91_pwm_leds() ARM: at91: at91sam9rl: switch to generic PWM framework ARM: at91: sam9263ek: use generic leds_pwm driver ARM: at91: at91sam9263: switch to generic PWM framework ARM: at91: sam9m10g45ek: use generic leds_pwm driver ARM: at91: at91sam9g45: switch to generic PWM framework Signed-off-by: Olof Johansson <olof@lixom.net>
